2019 Mazda Cx 5: Recalls, Complaints & California Lemon Law

I own a 2019 Mazda CX-5 with approximately 36,000 miles. The vehicle developed a strong burning oil smell while driving, particularly through the HVAC/vent system. I initially reported the odor to a Mazda dealership, but no issue was identified. Approximately two months later, the smell returned and worsened. The vehicle was later diagnosed by a Mazda dealership with an oil leak originating from the cylinder head near the exhaust manifold. According to the repair documentation, oil was accumulating on the exhaust due to seepage from the cylinder head. The repair required full cylinder head replacement. This created significant safety concerns because leaking oil was contacting hot engine/exhaust components while the vehicle was being operated. Burning fumes entered the passenger cabin through the vents while driving. I was concerned about the risk of fire, smoke inhalation, sudden oil loss, and possible engine failure while on the road. There were no warning lights prior to the failure. The primary symptom was the persistent burning smell. The dealership replaced the cylinder head. The original repair estimate was approximately $6,000. Mazda later provided partial goodwill assistance, but I was still required to pay approximately $2,500 out of pocket. After researching this issue further, I found numerous similar NHTSA complaints involving 2019 Mazda CX-5 vehicles experiencing cylinder head leaks/cracking near the exhaust manifold, burning smells, smoke or fumes entering the cabin, and major engine repairs at relatively low mileage. Mazda has acknowledged similar cylinder head concerns in CSP11 and TSB 01-002/23 for certain VIN ranges but denied coverage for my vehicle because the leak involved oil rather than coolant and because my VIN was outside the covered range. I am requesting that NHTSA investigate whether this represents a broader cylinder head defect affecting additional 2019 Mazda CX-5 vehicles outside the currently covered VIN range.

NHTSA #11736171

A Mazda Dealership should me a Mazda cx5 2019, in 2023, at nearly 38k miles, right about where many have reported a cracked cylinder issue due to a manufacturing issue in age, and in milage. There is a lawsuit ongoing regarding the turbo version, however many reporting the same issue in the non turbo versions. My engine started smoking while on the highway causing a highly dangerous scenario to which I was barely able to make it to a mechanic where all the oil spilled out upon arrival. I got a diagnostic from a reputable mechanic confirming the cracked cylinder.

NHTSA #11734157

The cylinder head cracked, causing a coolant leak, which then lead to the car overheating. My car was taken into Mazda dealership because there is a warranty extension for this specific part CSP111. The Mazda dealership, corporate, and warranty department all stated the known widespread defect cracked cylinder head will not be replaced on their behalf due to an overheating code. Mazda is using a symptom as an excuse to the problem. Due to the overheating code, Mazda recommended replacing the whole engine for $10,000 with 20 hours of labor. This defect part and Mazda’s unwillingness to provide a proper solution caused my car engine to fail, posing a safety risk. No symptoms other than low coolant were present, which my car was then parked, not driven, and towed to the dealership, in hopes the warranty would be honored.

NHTSA #11734784

We began occasionally smelling an acrid smell, but didn't think much of it due to lack of visible leaks or warning lights. During a routine oil change at the mazda dealer, we asked about the smell, and the tech almost immediately found the issue, saying he had seen it a few times before. The oil is leaking from the head down onto the manifold due to what seems to be a recurring defective casting issue. quote from mazda dealer service department "During the vehicle's inspection, found oil leaking from the engine. A further inspection found the oil to be leaking from behind the cylinder head near the exhaust manifold. oil is leaking through the casting of the cylinder head it appears. will recommend replacing the cylinder head due to the oil leak."

NHTSA #11743725

My 2019 Mazda CX-5 started to smoke from the engine and I could smell oil burning. My car was due for an oil change so I brough it to a mechanic. After a diagnostic, they determined that there was a major oil leak and that the cylinder head was cracked and suggested I take it to the dealership. I did and they confirmed that there was a cracked cylinder head causing the massive oil leak. The technician even said in a video sent to me that the oil is leaking "in the same place as the others". I was then quoted 5,960.75 to make this repair. I did research and found that this is a manufacturing defect that is long known to Mazda. There is a TSB and a CPS that extends the warranty for this issue but only for turbo engines, not my non-turbo engine. My car is 2 years past the warranty but I only have 32K miles on it. I asked if Mazda could cover all or some of the cost since it is a defect, not caused by anything I did or didn't do. I was then told that because I didn't take my car there regularly for service, that they wouldn't cover it. I regularly took my car in for oil changes and other maintenance to a local shop as the nearest dealership was almost 30 miles away so it was very inconvenient. It's outrageous that Mazda won't issue a recall or extend the warranty for the same issue in the non-turbo engines. Asking me to pay 6K for a defect they caused is unconscionable.

NHTSA #11722301

My 2019 Mazda CX-5 with approximately 78,000 miles developed a sudden major engine oil leak. The Mazda dealership diagnosed the issue as a cracked cylinder head and quoted approximately $5,600 for repair. The vehicle was properly maintained and this failure occurred without warning. A cylinder head failure at this mileage appears premature and may represent a defect. The oil leak created a large puddle under the vehicle and could pose a potential safety hazard due to loss of engine oil.

NHTSA #11723326

Cylinder head is cracked and leaking oil. The Cylinder head has an active warranty extension but Mazda only applies this to coolant leaks and not oil leaks. The root cause is a casting defect along with a exhaust manifold design issue that imparts undue stress onto the cylinder head causing cracks. The limitation of the warranty to the type of fluid that leaks rather than the failure due to design issues with the exhaust manifold and cylinder head does not make sense given that both components have been redesigned due to the prevalance of both coolant and oil leaks from cylinder head cracks. Problem has been confirmed by Quality Mazda Service departmetn on April 4, 2026 but no warranty coverage extended to repair the failure due to the fluid leak being oil and not coolant. No warnings or messages given prior to leaks. Leaks began at roughly 76,400 miles.

NHTSA #11735831

I am reporting a premature engine failure on my 2019 Mazda CX-5 with approximately 55,000 miles. The vehicle developed a significant engine oil leak that was diagnosed by a repair facility as a casting failure in the cylinder head behind the timing cover. Due to the location of the leak and the nature of the defect, the entire cylinder head assembly had to be replaced. The total repair cost was $5,262.32, which I paid out of pocket. The repair documentation indicates that Mazda has issued a Technical Service Bulletin addressing this condition, but there is currently no recall or warranty extension covering the issue for my vehicle. A cylinder head casting failure at such low mileage appears premature and not consistent with normal wear and tear on a properly maintained engine. An engine oil leak of this nature could potentially create safety risks, including oil contamination of engine components or the possibility of oil leaking onto hot engine parts. Because this issue appears to be documented by Mazda through technical service guidance and has resulted in a costly major engine repair at relatively low mileage, I believe it should be investigated to determine whether a broader manufacturing defect exists that could affect other vehicles. I am submitting this complaint so that the issue is documented and can be evaluated for potential safety concerns or a future recall if similar failures are occurring in other vehicles.

NHTSA #11722147

The engine cylinder head cracked and is leaking engine oil. This component is available for inspection at Liberty Mazda or by an independent certified mechanic upon request. The cracked cylinder head caused significant engine oil leakage, which created the following safety risks: Sudden loss of engine power or stalling while driving Smoke emission from the engine bay Potential fire hazard if leaking oil contacted hot engine components These conditions placed both the driver, passengers, and others on the road at risk. The cracked cylinder head and associated oil leak were diagnosed and confirmed by Liberty Mazda, the authorized dealership that performed prior repairs on this vehicle. The dealership documented the issue and provided a repair estimate of approximately $5,400. No independent service center has inspected the vehicle at this time. The vehicle and cylinder head have only been inspected by Liberty Mazda. Mazda Corporate has not physically inspected the vehicle, but all service records and documentation of prior repairs have been submitted to them during the warranty dispute process. There has been no inspection by police, insurance representatives, or other third parties May 2025: The vehicle intermittently struggled to accelerate. At that time, no dashboard warning lamps illuminated, and the dealership initially reported no issues. June 2025: Following the timing cover repair, the vehicle experienced engine oil leakage due to incorrect sealant installation, which was documented. February 10, 2026: The dealership repaired the oil pan seal and replaced the sealant, refilling engine oil. February 14–15, 2026: Approximately four to five days after the February 10 service, the cylinder head cracked, causing a significant oil leak. All symptoms and related service events are documented in Liberty Mazda’s service records.

NHTSA #11720489

The head on the 2.4L engine of the 2019 Mazda CX5 has shown a manufacturing defect that Mazda has addressed in certain models, but not all of the models with this engine. This leaves a large amount of vehicle owners with the financial liability to pay out of pocket for Mazda's engineering and manufacturing defect that they know about. The oil leaks onto the exhaust manifold creating a fire hazard. When driving our car, we cannot use outside air on the vents, A/C because the intake pulls in smoke coming from the engine compartment. I brought the car in today to Mazda and was denied any help in the repair, I am continuing with Mazda corporate to try and reach a resolution. Currently this will be roughly a $7000 repair. I do not have an estimate yet from the dealership.

NHTSA #11721866

I am being told there is a crack in the cylinder head that is a known issue for these vehicles. I have done some research online and it says that they installed defective cylinders in vehicles that were made between the years 2018-2020 leaving vehicle owners to pay thousands of dollars out of pocket due to a manufacturing defect. My car was smoking and smelling like something burnt even inside the car causing the driver to inhale those fumes, I took it to the shop and it turns out that the cylinder head is cracked and leaking the oil.

NHTSA #11709228

The vehicle has suffered a crack of the Cylinder Head Assembly which leads to engine oil leaking onto hot exhaust and fire hazard. This defect is officially documented by the manufacturer in Service Alert SA-031/21, which identifies a trend of aluminum heads cracking and leaking pressurized oil directly onto the hot exhaust manifold. Although Mazda has issued a 10-year/120,000-mile warranty extension (Program CSP11) for the exact same casting failure in its Turbo-equipped models, it has refused to provide similar "Goodwill" relief for my vehicle, despite it suffering from the identical engineering flaw. Mazda’s refusal to cover a verified latent manufacturing defect that poses a significant fire hazard is arbitrary and unfair. I am requesting that Mazda North American Operations provide full reimbursement for the $6,788.51 repair

NHTSA #11709993

While driving a short distance, my engine overheated and there was a strong burning smell. The cylinder head was cracked, causing a significant oil leak. The car is currently at the dealership but is available for inspection upon request. The defective cylinder head is leaking engine oil directly onto hot exhaust components. This creates an immediate risk of engine fire and causes smoke to enter the vehicle cabin, impairing visibility and driver health. The vehicle was diagnosed by an authorized Mazda dealership. They confirmed the cylinder head is cracked and requires replacement. My mechanic advised this type of leak could lead to engine overheating, sudden power loss, or potential fire risk and should not be driven. Mazda has issued prior Technical Service Bulletins and warranty extensions for similar cylinder head/manifold cracking issues on the 2.5L turbo engine, but no program exists for the non-turbo engine, despite identical problems. Mazda should be held responsible for this safety issue. Mazda is aware of this manufacturing defect but has not recalled these engines to be repaired or replaced if they are outside of their warranty period, placing costly repairs and potentially life-threatening situations on their customers. The repair is replacement of the cylinder head/sleeve or replacement of the engine block, which has since been modified by Mazda to resolve this issue. Mazda’s refusal to extend reimbursement to non-turbo owners is unfair and leaves affected customers with no support for a known manufacturing flaw. I urge NHTSA to investigate this recurring engine defect in non-turbo 2019–2020 Mazda CX-5 models and encourage Mazda to offer equal reimbursement.

NHTSA #11703943

The Cyclinder Head cracked. This could cause the engine to fail, and leaving the driver on the highway or other unsafe locations of travel. The certified repair shop along with the insurance adjuster advised it was a manufacturing defect. The warning sign was an oil burning smell inside the vehicle while stationary and inside the garage.

NHTSA #11700305

Question 1 - What component or system failed or malfunctioned, and is it available for inspection upon request? Answer 1 - The Engine Cylinder Head. The cylinder head developed a crack, causing a significant oil leak. The car is currently at the dealership but is available for inspection upon request. Question 2 - How was your safety or the safety of others put at risk? Answer 2 - The defective cylinder head is leaking engine oil directly onto hot exhaust components. This creates an immediate risk of engine fire and causes smoke to enter the vehicle cabin, impairing visibility and driver health.

Question 3 - Has the problem been reproduced or confirmed by a dealer or independent service center Answer 3 - Yes. The vehicle was diagnosed by an authorized Mazda dealership. They confirmed the cylinder head is cracked and requires replacement. The dealership acknowledged the failure and offered a partial repair discount, confirming their diagnosis of the defect. Question 4 - Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Answer 4 - Yes. The vehicle has been inspected by an authorized Mazda dealership technician acting as a representative for the manufacturer. I have also escalated the issue to Mazda Corporate (case number can be provided upon request), who reviewed the dealership's findings but refused to cover the full repair cost. Question 5 - Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Answer 5 - I noticed an oil leak on my driveway. I noticed it and brought it in to be looked at the first week of November 2025.

NHTSA #11702658

2019 Mazda CX5 has a cracked cylinder head. This is causing oil to leak out. The oil is leaking out onto the exhaust manifold which is causing the manifold to smoke and has the possibility to catch fire. Mazda is aware of this issue and issued CSP 11( customer service program). This does not cover the oil leak, only coolant leak. Several Class Action Lawsuits have been filed. Local Mazda dealership has inspected the car and confirmed the issue. The issue occurred suddenly with no warning. Again, Mazda is aware of this issue but has failed to issue a recall or service program to fix it, this is a dangerous issue as it can lead to a fire with the oil leaking onto the exhaust manifold.

NHTSA #11723140

In August 2025, we brought our Mazda CX-5 (non-turbo engine) to a Mazda service center and paid nearly $3,000 for repairs, including replacement of belts and other related service. Despite this, we continued to experience a burning smell from the vehicle. Shortly thereafter, the problem escalated — the burning smell persisted and smoke began to appear. Mazda is now demanding an additional $4,500 to replace a cracked cylinder head. This defect must have been present when the car was serviced in August, and the initial repairs failed to identify or correct it. While there is an NHTSA Technical Service Bulletin for the turbo version of this engine, there are numerous complaints online about the same defect in the non-turbo model, which is what we own. This indicates that the problem is not isolated. Mazda should be held responsible for this safety issue. A cracked cylinder head that leads to burning smells and smoke is a serious hazard that could cause engine failure or even fire. Consumers should not be forced to spend thousands of dollars on repairs for what appears to be a widespread defect and when our vehicle has only $50k miles and it should last for the life of the vehicle.

NHTSA #11691028

Confirmed cracked cylinder by dealership, led to dumping of oil while vehicle was in motion on the highway. Vehicle/engine could have caught fire at any moment. There were no engine warnings that appeared on the dash. This is consistent with other CX-5 complaints on NHTSA. Vehicle had 55,000 miles on it at time of incident, and needed $8,000 worth of repair. Please recall!!

NHTSA #11693919

Cracked/Leaking Cylinder Head on my 2019 Mazda CX5. It is understood that Mazda has extended warranty for the Turbo Model (CSP11) of this car, but not the standard engine, even though they both are displaying the same issue in many 2019 CX5s. Quoted at $6000 for a vehicle under 90K Miles. Issue needs to be escalated.

NHTSA #11687965

No engine warning lights or other messages appeared. My car is a 2019 mazda CX-5 and has 31,954 miles. This problem has been confirmed by both an independent mechanic and the dealer service center. On 08/22/2025, I took my vehicle to dealer service for the repair. I also submitted a ticket to Mazda care for review of the case.

NHTSA #11682520

The engine has an oil leak from the head. It is a common problem with this year and make. It is a manufacturer's defect called a porous head where oil leaks through the casting not a seal. I've already spent $2000 to repair but still leaks. Oil leaks onto the exhaust and smokes causing fumes in the inside of the car and can be a fire hazard. Mazda is well aware of the problem but has yet to address it.

NHTSA #11744167

My vehicle has 64k miles and has had regular maintenance - oil changes, etc. it has recently developed an oil leak. I took it to the dealer today & they said the cylinder head and gasket needs to be replaced. My car has not overheating or even run warm. I understand there are 2019 CX-5S that have had a casting issue with cylinder heads. I feel sure that’s what the issue is here yet they want almost $6k to repair my vehicle!

At 30,000 miles car began leaking oil severely and was told that the engine block was cracked and needed to be replaced. There are numerous complaints of this same issue online happening just after the warranty has expired. The cost of repair is $6000.

NHTSA #11657420

Cracked cylinder head. Major oil leak. Oil light came on but then turned off. No other warning light. No engine light came on. The vehicle was taken to the dealer for diagnosis.

NHTSA #11647768

The engine cylinder head cracked before the vehicle hit 50,000 miles. This caused oil to leak and burn in the engine compartment, leading to a burning smell coming into the cabin. Once enough oil had been lost, I got a low oil pressure light. I immediately pulled over and noticed white smoke was coming out from under my hood, and the smell of burning oil was quite strong. The problem has been confirmed by my mazda dealer. The vehicle has not been inspected by manufacturer, police, insurance. Just the dealer. The vehicle is currently at the dealer, and the cylinder head would need to be removed for inspection if requested. The smell of burning oil was the only early symptom, though I did not recognize it at the time.

NHTSA #11654488

I had my vehicle looked at and found a cracked cylinder head on #3 and did some research of people having the same issues. I was driving when the vehicle started smoking it turns out the oil coming out of cylinder #3 flows down the driver and passenger side behind the exhaust manifold which can lead to a fire. My car only has a little over 80,000 miles and this should not happen around that low of a mile vehicle. I believe this is an issue that needs attention.

NHTSA #11650383

The contact owns a 2019 Mazda CX-5. The contact stated that while driving up on incline at 45 MPH, the engine shut off with the check engine warning light flashing on the instrument panel. Despite the failure, the contact was able to pull the vehicle off to the shoulder of the road. Due to the failure, the vehicle was towed to the residence. The following day the vehicle was towed to an independent mechanic; however, the mechanic was unable to duplicate the failure. The mechanic replaced the spark plugs and the ignition coil. The mechanic referred the contact to the dealer for additional assistance. The contact drove the vehicle to the dealer with an abnormal rumbling sound coming from the vehicle. While at the dealer, the dealer was unable to determine the cause of the failure. The contact was provided an estimate for repairs unrelated to the failure. The manufacturer was notified of the failure and provided a case number. The vehicle was not repaired. The failure mileage was a 129,000.

NHTSA #11652845

The cylinder head on my 2019 Mazda CX-5 failed prematurely due to a known defect. The vehicle is currently at Fred Beans Mazda in Mechanicsburg, PA, where the issue has been diagnosed and confirmed. The defective component is available for inspection upon request. This failure created a serious safety risk due to an oil leak, which led to smoking from the engine bay and a potential fire hazard. If the oil had ignited, this could have caused severe vehicle damage or injury. Additionally, the failure could lead to a sudden loss of power while driving, increasing the risk of an accident. The problem has been reproduced and confirmed by the dealership, and Mazda has been contacted regarding assistance. They have acknowledged the issue but have not provided full coverage for the repair. Prior to the failure, there were no warning lights or messages. The only symptom was an oil leak, which led to smoke coming from the engine. This issue appears to be a common problem with this model, and Mazda should take responsibility for addressing it properly before it causes serious harm.

NHTSA #11646253

This concerns a 2019 Mazda CX5 with approximately 52,000 miles - the engine of this vehicle is the 2.5L naturally aspirated version. Driving the vehicle with the HVAC system on resulted in a burning oil smell coming through to the cabin. Upon owner inspection, engine oil was seen as coating the underside of the vehicle in various areas. The oil pan drain plug and oil filter were both found to be tight and not leaking oil. The vehicle was taken to a nearby Mazda dealership for inspection on 2/26/2025. On 2/27/2025, Mazda technicians state that the cylinder head on the vehicle engine requires replacement. Replacement is quoted to be in excess of $5000. Reviewing the issue online shows numerous similar cases of engine cylinder head failure. This vehicle comes equipped with cylinder deactivation which seems to have a higher rate of failure regarding cylinder heads and a potential design flaw with cylinder heads manufactured in a time frame of 2018-2020. Leaking oil could potentially start a fire as the oil drips onto the exhaust manifold when the car is at operating temperature.

NHTSA #11645329

The cylinder head in the engine cracked while I was driving. The vehicle was leaking oil profusely and was down a quart after the oil had been changed the week prior. There were no warning lights or indication and I had just had the vehicle in the dealership the week before. I'm a disabled driver that requires hand controls so if I needed to exit the vehicle and move away from it it would not be possible. It's been at the dealership since 2/24/25. I have found numerous other people that have experienced the same issue online.

NHTSA #11646912

Valve cover develops crack causing significant loss of oil resulting in seizing of engine with the potential of serious accident and potential loss of life.

NHTSA #11651964

While driving the vehicle, I started smelling a burning smell about 10 days ago (2/17). I also felt a slightly reduced engine performance and could see the car emitting smoke from the engine bay. I had no warning lights on my dash. For all I know, the engine could've blown while I was driving on the road. Upon taking the vehicle to the dealership 2 days ago (2/25), they informed that my car has a cracked cylinder head, and there was no apparent reason why this would happen. The vehicle has only been inspected by the dealership thus far and I was quoted $5,700 to fix the issue. Upon looking up the problem, I see this is a common issue, with many having experienced it before, but no TSBs issued for this. There is a CSP issued for vehicles of the same year, but limited to the Turbo version on the engine. Unfortunately, I do not have any warranty on the car currently.

NHTSA #11645265

Engine has a crack in the head, well under 100,000 miles. It's a known defect but Mazda refuses to do anything about it. It is currently a very expensive paperweight sitting under our carport.

NHTSA #11723966

Oil started leaking while car was idling causing smoke to enter the cabin as well as all under the hood. Car was undriveable at this point. She was lucky there was no traffic. Car had to be towed and cylinder head was cracked. Mazda has a known faulty cylinder head problem they have refused to fix and this caused a safety issue. Vehicle will not be able to be inspected as we had it towed to get fixed immediately. The service center did confirm this is the issue and there were no prior issues before this.

NHTSA #11637185

I own a 2019 Mazda cx 5 and it has 78,000 miles. I noticed smoke coming from the engine and a lot of oil leaking on the ground. I brought the car into my independent service center and they confirmed that there was a crack in the engine cylinder head. There is a TSA # SA-031-21 on this problem. I feel that my safety was at risk, since the engine could have seized while driving. This vehicle is available for inspection upon request. No warning lamps or messages were displayed, however there was a strong odor of burning oil. This problem occurred on 1/9/25 and it has been in the service center since.

NHTSA #11635920

My 2019 Mazda CX-5 suddenly developed a major oil leak within the last 7 days. My car has only 44,350 miles and I have had all scheduled and required maintenance completed timely, including oil/filter changes, coolant level checking and maintenance, etc. I took the car to an independent mechanic who diagnosed the problem as a cracked cylinder head. I then took the car to a local Mazda dealer who confirmed the diagnosis and informed me that there would be no warranty coverage as my 60,000 mile/60 month powertrain warranty had expired 60 days earlier. Some two years earlier my car's check engine light came on and overheated. I took it to the same local dealer, who replaced the coolant control valve & related components. In November 2024 I received a "Warranty Extension Program" letter from Mazda about the same fail-safe thermostat problem. I believe this is relevant and related to the cracked cylinder head since almost all instances of a cracked cylinder head are due to engine overheating. This issue put me at risk as I was close to driving the car with no oil and oil leaking heavily onto very hot engine components that could have resulted in a fire. I am now facing repairs to this car between $4,800 and $6,000 and given the faulty/defective cylinder head from Mazda, I could face this safety issue again, as it will be replaced with a similar cylinder head from Mazda!

NHTSA #11633924

As I was driving, a burning smell emanated from the car. There were no check engine lights on. When I pulled over, I saw a lot of smoke coming from the engine. I checked the oil level and it was above the minimum line bit just barely, even though my husband had just done an oil change on it. I refilled the oil and continued on my trip. The problem repeated for several dqays until I got home and took it to the Mazda dealership. They reported the following: "Cylinder Head Assembly: oil leaking out of back of head, recommend replacing cylinder head and related gaskets. The cylinder head sits above the cylinders on top of the cylinder block. It closes in the top of the cylinder, forming the combustion chamber. This joint is sealed by a head gasket. In most engines, the head also provides space for the passages that feed air and fuel to the cylinder, and that allow the exhaust to escape." This service is $5600! My car only has 80K miles on it. This is a safety issue because there was no warning. No check engine light appeared and there was no warning.

NHTSA #11635981

NHTSA #11631605

My Mazda CX-5 was found to have a cracked cylinder in the engine and was profusely leaking oil. When I spoke to the dealership they denied seeing this regularly, however, upon doing research on reddit, it is found to be more pronounced than indicated. There was no known cause indicated, however, on reddit it appears that the original casting done in Mexico maybe the culprit because it is so thin and causes it to crack between 40-50k miles. There is no other sign or warnings, besides an obscene amount of oil leaking. The failure of this could cause the engine to fail while driving. This is a significant risk.

NHTSA #11631310

Vehicle has 40k after a oil change noticed oil spots on pavement took it back to the garage that did the task, was told that the leak was near cylinder #2. Called Mazda customer service and was informed that my warranty expired in May of 2024. my mechanic called Mazda parts to get the price of cylinder head and was told that they had a run on cylinder heads due to defective heads coming from the Factory, SHOULD BE A RECALL ON THE MAZDA.

NHTSA #11629000

This car has less than 37,000 miles on it it has significant oil leaks from the valve cover gasket, it’s timing cover gasket and now it had been determined it has a cracked cylinder head. This was covered by 3 Service alerts with the cracked cylinder head being SA-031/21. None of the dealers notified us of the issue when serviced Galpin Mazda and New Century Mazda. But Big O Tires did. The two oil leak gasket repairs cost over $1600. The car is 8 months past warranty. The car is burning oil when driven. Due to the leak and the smoke particles and smell enter the cabin. The engine smokes when shut down instill it cold down. The smoke particles in the cabin are dangerous. The engine oil light appeared in late November (my daughter’s car, she is away at college). We found out the depth of the oil leak issues the second and fourth week of December. The fact that the dealers did not notice us or do preemptive repairs is a major failure by the Mazda organization.

NHTSA #11632866

Brought 2019 Cx-5 to local dealer with complaint of strong smell and smoke coming from hood. Cracked cylinder head at only 21k miles. Known flaw for this particular make and model. Only 6 months out of warranty. Mazda refuses to make it right and only extended warranty for turbo engines. Mazda needs to make this right for ALL engines with this issue.

Car was purchased in June 2019. Car started smelling like burning oil and started finding oil pooling under the car around November 2024. At time the incident was discovered, car only had 38k miles. There was no warning lights or indication there was an issue other than the smell and small pool of oil under car. The Mazda service manager immediately knew what the issue was and told me they were going to confirm with a full inspection and diagnosis. I was told that I have a cracked cylinder head and I will need to have it replaced. Warranty ended few months prior so they will not cover. I was told it would cost $4589.76. The Mazda service department told me that this is a common issue and to hold off on repair and contact Mazda corporate since warranty just ended. They topped off my oil and told me to keep an eye on the oil level and to wait to hear back from Mazda corporate.I submitted a case with Mazda and the customer care specialist told me that they cannot guarantee they will cover this. Within a week, the temperatures got colder and issue got worse. Low oil light came on, topped off with oil. Lost 4 quarts in one day. Called Mazda service and they told me to top off oil and come drop car off immediately. Upon researching this issue, the cracking of cylinder heads in Mazda CX-5 vehicles, particularly those with the 2.5-liter (NA) engine were widespread and discussed in online forum. The contributing factors of the issue point to a design flaw of the cylinder head due to the cylinder deactivation technology and a manufacturing defect due to the cylinder head casting process based on reports and discussions within the automotive community. A TSB (SA-013/22) has been released for the affected cylinder head with a modified replacement. This seems to be a significant and widespread issue that can cause entire engine to fail and require full replacement. Oil leaking on to the hot exhaust near other engine parts could ignite and put myself or others at risk.

I have 115k miles on my 2019 CX5. Never has any issues. Now all of a sudden I have a cracked cylinder head leaking oil. I was smelling smoke but mot seeing it. I took into dealership they noticed oil dripping thus why smell. Its a $4500-5000 job. I cannot afford this. This should not happen at this kind of mileage. My warranty just expired too. Mazda needs to cover these type of repairs

At 49k miles and 4 months out of warranty, the car began leaking oil and smelling like smoke. The dealer diagnosed with a cracked cylinder head and repaired it.

NHTSA #11619514

While driving, I received a warning that the engine in my car was overheating. Upon arriving home and parking, I noticed pooling under the car. My car was due for an oil change so the next day I dropped off the car for the oil change and mentioned the overheating message and leak to the technician thinking the fix would be routine. To my surprise, I was told my vehicle had a serious coolant leak related to a cracked cylinder. I was advised to take the vehicle to a Mazda dealer. Morrie's Mazda in Minnetonka, MN confirmed the cracked cylinder head which required a full engine replacement despite the car being only ~5 years old and having ~63,000 miles. Mazda had issued a technical service bulletin on this issue but had not issued a recall. As a result, I was left with a large repair bill to replace the engine in a relatively new car. This is a serious issue and I feel Mazda put my life and others in jeopardy by not recalling vehicles and letting customers drive with the risk of the engine overheating.

NHTSA #11617780

Coolant leaks at cylinder head on 2019 Mazda CX-5 Grand Touring Reserve. Mazda North American Operations released a technical service bulletin (01-013/21) regarding 2016-2020 Mazda CX-5, CX-9, and Mazda6 with SKYACTIV-G 2.5T engines. This issue can cause the engine to leak coolant, overheat, and stall, potentially leaving the driver and passengers stranded in an unsafe location. Mazda is aware of this manufacturing defect but has not recalled these engines to be repaired or replaced if they are outside of their manufacturers warranty period and placing costly repairs and potentially life-threatening situations as the responsibility to their customers. The diagnosis to repair this issue is a replacement of the cylinder head/sleeve or replacement of the engine block, which has since been modified by Mazda to resolve this issue. This is a costly repair for diagnostics, labor hours, and parts and Mazda is refusing to be held responsible for these defects outside of the power train warranty period. Mazda customer support advised this will only be potentially covered if diagnostics are completed at a Mazda dealership and does not provide any assistance if the customer uses a non-Mazda affiliated repair shop. Messaging on the dash console advised excessive heat and thermostat was nearing 260°F

NHTSA #11616241

Started smelling smoke randomly and discovered an apparent oil leak in the engine. Mechanic inspected and noted that it appears to be an issue relating to the cylinder head/head gasket, which is in line with a technical services bulletin put out by Mazda several years ago for this make/model/year for a known design flaw that can result in catastrophic engine failure. I am just outside the five year warranty but well under the 60,000 miles, so expecting them to tell me they won't cover the repair even though this should have been a recall due to the potential outcome. I cannot drive the vehicle until this is repaired because it can cause engine fires (or worse).

NHTSA #11616035

My vehicle started smoking and I smelled a oil burning smell coming through the vents. I took it to the Mazda dealership and they diagnosed it with a cracked cylinder head. The repair estimate is $4,900. It is a 2019 with less than 60,000 miles, but it is a few months out of the powertrain warranty. However, this is a KNOWN issue to Mazda. As I have been researching online, many Mazda CX-5 owners have reported the same issue and I believe Mazda has traced it back to defective manufacturing in a batch of these parts. My local mechanic has also told us that he has seen this issue with 2019 Mazda CX-5s and recommended we report them. Mazda SHOULD issue a recall, but I understand that is expensive for them. At the very least, they should alerting drivers to this possibility and voluntarily repairing these cylinders without cost to unsuspecting drivers who could end up with an engine fire. I have submitted a complaint to Mazda customer service and I am awaiting a response.

NHTSA #11613576

There is a coolant leak at the cylinder head. We have been told that the cylinder is cracked at the back of the cylinder head where the exhaust ports meet. The dealer's technician said there is a "redesign" in the cylinder head. This is a known issue that is a defect apparently due to Mazda's design of securing the turbo on exhaust studs that are not designed to hold the weight. Why has there not been a recall? There is a Mazda TSB - 01-013/21, issued 10/15/2021 Verbal estimate from dealer for repair - over $7,000

NHTSA #11614947

This report is for a 2019 Mazda CX-5 with the Naturally Aspirated/Non-Turbo engine. This vehicle only has 26,500 miles and has developed a major oil leak from a cracked Cylinder Head. The continued safety of the vehicle has been degraded. The engine could seize while driving making the vehicle inoperable while on roadways. The vehicle has been inspected and confirmed by both an independent service center and by an authorized dealer service center. The only warning lamp that appeared was a low oil light. I immediately pulled over for safety and inspected the oil levels of the engine. I determined the engine oil levels were just below the fill line on the dip stick. I then added approximately half a quart of recommended oil and the oil warning light turned off. I then contacted a local service center for diagnostics of the problem. They determined the cause of the oil leak which was a Cracked Cylinder Head on the Engine. I then drove the vehicle to an authorized Mazda service center at the dealership. They also diagnosed the problem as a Cracked Cylinder Head on the Engine. Both the independent service center and the authorized Mazda service center recommended a full Engine replacement.

NHTSA #11610809

The 2019 Mazda CX5 GT started to make a clicking noise coming from the engine. After much investigation online, sharing multiple resources of videos and sound this seems to be the hydraulic lash adjusters for this specific year and model. Unfortunately this is outside the normal warranty and wasn't noticed until now. The car was inspected by local independent service center. This would pose risk to my family and others if the vehicle seized to work properly. There were no warnings given other than the clicking noise and inspected.

NHTSA #11604422

The contact owns a 2019 Mazda CX-5. The contact stated while driving 35 MPH, the vehicle was smoking. There were no warning lights illuminated. The vehicle was taken to the local dealer but was not diagnosed or repaired. The vehicle was taken to an independent mechanic, who determined that there was oil leaking from the main gasket and referred the contact to the dealer. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 31,000.

Crack head leaking oil

NHTSA #11590013

The Cylinder head cracked and caused oil to spill out. This was inspected at Towne Mazda in Orchard Park, NY. I was driving ~50 miles when the issue occurred, and had driven approximately 40 of the 50 miles when me and my sister pulled over and noticed my engine smoking and the burning smell to be pungent. Had I not pulled over, It could have led to engine misfire and damage to other parts of my vehicle. The Dealer confirmed the need for a new cylinder head and parts, and is currently repairing the vehicle. The Component was not recently inspected by the manufacturer, police, insurance. During the course of driving, after about ~35 miles, the oil pressure light turned on. I drove roughly 5 more miles before I pulled the car over to have it towed to my Mazda dealership.

Had a constant Valve tick on cold starts and sometimes while running long periods. Oil level top offs and changes did not remedy the issue. Mechanic says it's a bad valve lash adjuster.

NHTSA #11578393

I developed a cracked cylinder head in my 2019 Mazda CX-5 that only had 33,000 miles on it. I lost approximately 50% of my oil in a 4 mile drive. I believed I had been leaking oil, checked the dipstick, drove 4 miles (max speed of 35 mph), smelled the burning oil, pulled over, saw smoke coming from the hood and checked the dipstick again. Losing this much oil is a safety risk with the possibility of a fire especially if driving at a faster speed and inability to have a safe place to pull over along with smoke from the burning oil causing visibility issues which at higher speeds such as on an interstate can cause a safety concern. No indicator lights/messages appeared, this was determined from seeing what I thought was oil on the ground and then checking the dipstick. Mazda is well aware of the issue. When picking up the car for the dealership after being fixed, I asked what kind of parts were used to ensure this does it happen again. The shop employee said they were “revamped” parts due to the known issue with this model and pointed out 4 other Mazda cx5s currently in the shop with the same issue getting repaired.

NHTSA #11572881

My engine started smoking while I was driving fast got out of car oil leaking everywhere there was a crack in the cylinder head, another few minutes of driving and the car could have burst into flames seems like it’s a common issue with Mazda cx5 a quick google search has shown me I’m not the only one with this issue, worst thing about it is Mazda refused to fix it.

NHTSA #11567484

My engine suddenly started smelling like burning oil. I was due for an oil change and needed it immediately so I went to a quick oil change shop. They told me oil was sprayed all over the engine and I should take it to the dealer. It's been at Napleton Auto Park in Urbana, Illinois for a week and they finally diagnosed a cracked cylinder head. They said it could take up to 2 months to repair and they're checking to see if it's covered by my warranty.

Cracked cylinder head which caused engine to leak oil and smoke

NHTSA #11556343

Noticed the smell of burning oil in the cab on 30 mile drive. No warning lamps or other symptoms; vehicle continued to operate normally. After parking and inspecting the engine for the burning smell, noticed oil dripping from underneath engine bay and a pool of motor oil was forming on the ground underneath the vehicle. The next day, vehicle was brought to local Mazda dealer for inspection. They diagnosed the cause and stated the engine needs a cylinder head replacement. Oil leakage was so prolific, if this were to occur during a long distance drive, the engine would have lost all of the oil and stranded motorist - safety concern. Cylinder head failure is a known issue (Mazda TSB [XXX] ) with this engine. This known safety issue should trigger a recall. At minimum, the repair should covered by manufacturer for life of vehicle.

Cracked cylinder head with oil leaking. There were no warning from my car prior to a diagnostic test. The car has a very strong rubber burning smell and white smoke comes out from the engine part before I took my car back to the Mazda Dealer. From a quick search, the cracked cylinder problem seems widespread with the 2018-2021's Mazda Cx-5. Took the car back to the dealer and dealer replaced the head cylinder and gaskets. There were no warning from the car.

NHTSA #11548816

The touchscreen digitizer on the Mazda Connect infotainment system has developed a known defect causing constant phantom/ghost touch inputs. The screen registers random touches without any physical contact, causing the system to navigate through menus, change vehicle settings (including safety-related settings such as blind spot monitoring and heads-up display), exit navigation mid-route, change radio stations, and initiate phone calls to contacts without driver input while connected to Apple CarPlay. This is a significant driver distraction and safety hazard. When the system begins making random inputs, the driver must divert attention from the road to attempt to regain control of the infotainment system or end unintended phone calls. The issue occurs most frequently when the vehicle is stopped or at low speeds but also affects the system while driving. This is a well-documented hardware defect affecting 2017-2020 CX-5 models, acknowledged by Mazda under TSB 09-003/22. The cause is a failing touchscreen digitizer, not a software issue. Mazda has not issued a formal recall despite widespread reports. The component is available for inspection upon request. The vehicle has not yet been inspected by a dealer for this specific issue. No warning lamps or messages preceded the failure — the phantom touch inputs developed gradually and have worsened to the point that the infotainment system is nearly unusable. Current mileage is approximately 60,000-80,000 miles.

NHTSA #11718237

The contact owns a 2019 Mazda CX-5. The contact stated while driving at an undisclosed speed, the instrument panel independently switched between features. The contact stated that the failure was persistent. The vehicle was taken to the dealer, however the vehicle was not diagnosed. The contact was requested to pay a diagnostic fee, the contact declined. In addition, the contact was informed that the failure was a known failure with the vehicle. The manufacturer was not made aware of the failure. The failure mileage was approximately 35,000.

Infotainment screen malfunctions, pressing buttons by itself.

NHTSA #11619242

Just as the recall issued for the 2014-2016 the Mazda Connect Touch Screen continues to be an issue for most owners with this Infosystem. Mine for two years since I bought it will do the “ghost touch” on its own, literally operating on its own. My settings change on their own, doing such things as the volume on its own going from a normal tone to blasting, causing such alarm that I’ve nearly gone off the road. My back up screen brightness changes on its own, causing a real safety concern of running into something or someone. This is just two examples…all of the functions go “haywire” and just change at any unexpected time. This issue can be seen over and over online by Mazda owners. And I’ve reached out to Mazda themselves who state they are not aware of any issue, yet the dealerships are well aware of this dangerous issue and quickly know exactly what the issue is when you explain what the car is doing and let you know that for $1200 they can replace the info system. I just don’t see how they can have this issue since at least 2014 and continue to sell cars with the same issue a recall was issued for. It’s so dangerous.

The electrical system malfunctions repeatedly. The volume on the navigation will set to maximum by itself. This is alarming and poses a safety risk. It also randomly texts people detailed location information of the driver. This is a safety risk for minors and people in abusive relationships or with a PFA order. It appears to be a common problem with this car.

NHTSA #11578338

The infotainment screen is malfunctioning and acts on it own. Random parts of the screen are touched on its own creating a lot of distractions. Examples are changing of screens, settings, ending my navigation, calling contacts etcetera. This is a huge safety hazard and Mazda dealerships are charging for diagnosis for a commonly known issue, claiming the cause is unknown, despite numerous posts and threads online linking this to a screen delaminiation issue.

NHTSA #11584063

The display screen appears to initiate "ghost actions". It will change songs, put phone calls on mute/hang up, change display settings etc. on its own. I looked this issue up online and it seems to be very common with 2017 and newer Mazdas. I took it to the Mazda dealership and they wanted to charge me $150 for a diagnosis and another $500 for a screen repair. I decided not to do it because all of the threads online stated that this didn't fix the issue so no diagnosis was made. It doesn't put me at extreme risk but it is very distracting when I am using maps or CarPlay.

NHTSA #11612892

There is a known “ghost touch” issue with this vehicle. I did not realize that until recently but the infotainment screen will randomly activate when at low speeds and/or stopped. This has caused distractions while driving as sometimes it will actually initiate phone calls on its own. Mazda has a technical service bulletin on this but has issued no recall

The 2019 CX-5 AWD with the 2.5L NA engine (with Cylinder Deactivation) has an engine oil leak coming from the cylinder head area. The Mazda dealer confirmed the leak source and found burnt oil on the exhaust. The component is available for inspection. The leak location and symptoms are consistent with the known porous/cracked cylinder-head defect documented in this engine family. Full confirmation requires teardown. In early Dec 2025, a burning oil smell began, then thick white smoke came from under the hood while driving and after stopping. This created an immediate fire risk, and rapid oil loss could cause sudden engine failure or stall in traffic. The issue was inspected and confirmed by an independent mechanic, who noted the leak could only be traced after removing the exhaust manifold. The Mazda dealership then inspected it and confirmed the leak source at the cylinder-head area and the burnt oil residue. The problem has been reproduced and confirmed by both the independent mechanic and the Mazda dealer. No warning lights or messages appeared prior to the smoke. Mazda has an extended warranty program for the same cylinder-head defect on the Turbo engine, but no equivalent coverage exists for the NA engine, despite the identical safety risks.

NHTSA #11704576

What component or system failed: The cylinder head failed due to cracking around the exhaust manifold, resulting in exhaust and coolant leakage. My independent mechanic and the Mazda dealer both confirmed this was the source of the burning smell and engine risk. The failed parts are currently in the possession of the Mazda dealership and available for inspection upon request. Safety risk: The failure created a strong burning rubber smell inside and outside the vehicle while driving. My mechanic advised this type of leak could lead to engine overheating, sudden power loss, or potential fire risk if not caught early. I frequently transport children in the vehicle, and the unexpected engine damage posed a significant safety concern. Has the problem been reproduced or confirmed: Yes. The issue was first diagnosed by an independent, certified mechanic and then confirmed by the Mazda dealership, who determined the cylinder head had to be replaced due to premature cracking and leakage. Has the vehicle/component been inspected: Yes. The vehicle has been fully inspected by an independent mechanic and the Mazda dealership service department. The dealership stated the failed cylinder head will be sent to Mazda for engineering review. Were there any warning lamps or symptoms before failure: There were no warning lights or error messages prior to the failure - which is alarming. The only initial symptom was a strong burning rubber smell that began shortly before the diagnosis. No overheating warnings appeared on the dash before the problem was confirmed. Additional context: The vehicle has 40,000 miles, has been fully maintained according to schedule, and is garage-kept. The Mazda service department acknowledged this failure is unusual and premature. Mazda has issued prior Technical Service Bulletins and warranty extensions for similar cylinder head/manifold cracking issues on the 2.5L turbo engine, but no program exists for the non-turbo engine, despite identical symptoms.

NHTSA #11701184

Just got diagnosed with cracked cylinder head. After looking on social media, it appears this is a thing for the model years 2018 and 2019. Bad casting? Anyway I believe this should be a voluntary recall to correct such a flawed engine. I bought this new from a Mazda dealership and kept it up to date with service only through the dealer. The 60 month/60,000 mile drive train warranty ran out last July. However I only have 50,000 miles on the car...babied.

Had the sudden onset of strong exhaust fumes in the cabin as others have described - especially when idling at a light. Returned to dealer after having it up on a rack to find oil dripping everywhere (shield underneath prevents from seeing drops when parked) - got word today it is indeed the cylinder head assembly. How is oil running on hot exhaust not a fire concern? I had to roll my windows down for fresh air in zero degree weather the fumes were so strong inside the vehicle. On top of that the P0126 (thermostat stuck open) diagnostic code is back for the second year in a row after having the “fix” installed under warranty last year.

The 2019 CX-5 has approximately 31086 miles. It was discovered that the cylinder head is cracked and causing the car to leak oil.

NHTSA #11560422

My 2019 Mazda CX-5 cylinder head cracked at only 60,000 miles. I noticed my breaks were smoking and stopped driving. I then noticed oil leaking from my engine which had blown into my breaks, causing the smoke. There was no check engine indicator on my dashboard, nor did it indicate that my engine had overheated. There was no indication that there was any issues with the vehicle until i noticed the smoke coming from my brakes. I towed the vehicle to the Captial Mazda Dealership in San Jose, CA. Per Mazda Dealership Repair Estimate: "cylinder head cracked by cylinders 2 and 3". When i asked the dealership service center why this happened, their only response was it was a engine failure and that "over time the cylinder can become warped and crack" and while it that doesn't happen often "it can happen" I asked if there was anything I did that caused this, their only response was "i can check with the technician again". Apparently I did not purchase the "extended warranty" so while the repairs are no fault of my own, I have to pay the $6,000 repair cost.

We were locked out of the car on a road trip due to a dead battery. We needed to open the car door to pop the hood in this emergency situation. With the Battery down, we had to use the physical keys provided by Mazda to unlock the door. Both Mazda's original keys did not open the driver-side door. We were stranded and had to call emergency key services to open the door. The purpose of physical keys is to open the car in case of emergency but in Mazda CX5 case they were useless. We have also reported the issue to Mazda and are awaiting a response.

Mazdas infotainment system was issued defective. The system is plagued with issues in which a “ghost” touch on the screen makes changes to the system. It is a very distracting issue and poses a safety concern as it distracts the driver from the road as the ghost touch can make changes on the infotainment system moving between settings, changing music, making random calls, and randomly triggering voice assistant if an Apple car play is connected. This is a known issue for which Mazda has a fix but has never issued a recall. If you search online you will find hundreds of examples of the ghost touch affecting Mazda vehicles.

I’m reaching out regarding a persistent issue with my Mazda 2019 cx5 infotainment system. The screen is experiencing frequent “ghost touch” or phantom button presses, where functions are activated without any input. This makes the screen erratic and often unusable, creating a distraction and raising safety concerns while driving. I’ve already restarted the system and attempted basic troubleshooting, but the issue continues. I’ve learned that this is a known issue in various Mazda models, and I believe this should be covered for repair, especially since it impacts both functionality and driver focus. I’ve already contacted Mazda customer service and my local dealership; however, they advised that the repair would need to be paid out of pocket. Given the nature of the issue and the potential safety concerns it presents, I strongly believe this is something that should be covered by Mazda. Please let me know how I can escalate this issue for formal documentation and create a new recall.

Mazda ships a defective touchscreen that will degrade and eventually register phantom inputs to the infotainment system. In my vehicle, the screen was able to randomly access my settings, including for safety (blind spot monitoring) and display (driving units, heads up display, etc) and start messing with my settings. When I was using maps, the screen would randomly zoom into different spots, or change my destination, or modify settings. This was an enormous distraction and rendered the screen useless. Also, I was never sure if I stopped the car from changing settings related to vehicle safety because I can't keep my eyes on the screen while I'm driving. It was just registering random inputs all over the screen while the vehicle was in motion.
