Hyundai Tucson 2023: Retiros, Quejas y Ley de Limón de California

The reverse beeping is just too loud for an Hybrid and many people online agree. I fully agree with having mandates for electric vehicles for safety concerns however they should not be so loud that they are louder or near as loud as a commercial truck and disturb residents. In fact Hyundai responded to the complaints by re-designing it for 2025 and newer facelifts but won't give any services to upgrade it to newer versions. I fully believe that Hyundai should and must offer services to use the new updated VESS.

Component that is unsafe: Moonroof Glass Taking in for inspection tomorrow. Safety risk: While driving on highway, Glass Spontaneously Popped and fully shattered. Glass fell down onto myself and into the car as I was driving. This put my driving at risk. Major distraction as well as potentially being a harm to my physical self. Problem reproduced? I know that there are other reports on moonroof glass on a Hyundai Tucson cars that have been shattered with the same predisposing factors. Hyundai has also been reported to not take accountability claiming that foreign objects were the cause. No this vehicle has not been inspected, but I will be taking it in on Sunday. There were zero warnings before this.

Dear Commissioner and DMV Officials: I am writing to formally address a serious financial and safety concern affecting vehicle owners in Connecticut. As a driver with over 50 years of experience—32 of those in CT—I have never experienced rodent damage to any vehicle until purchasing my 2023 Hyundai Tucson. Since acquiring this vehicle, I have suffered thousands of dollars in damage from rodents chewing through the wiring and wire housing. Multiple mechanics have confirmed this is due to manufacturers switching to soy-based and plant-derived biodegradable materials in wiring insulation. These materials are effectively edible, attracting rodents year-round—not just in cold months. This is not owner negligence. The root cause is a material deficiency in the vehicle's manufacturing. Consumers should not bear the financial burden of a known design choice made by the automaker. Repairs are costly, often excluded from warranties, and frequently not covered by insurance. I respectfully request the Department: Investigate the scope of rodent damage complaints linked to bio-based wiring in newer vehicles. Coordinate with NHTSA to evaluate whether this constitutes a safety defect warranting a recall. Advocate for regulatory standards requiring rodent-resistant wiring materials. Urge manufacturers like Hyundai to offer warranty coverage, reimbursement, or retrofits for affected vehicles. I am prepared to provide documentation of my repair expenses upon request. Thank you for your attention to this matter. Respectfully submitted, [XXX] cc: NHTSA, CT Attorney General, CT Consumer Protection, Hyundai Consumer Affairs INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I received a Recall notice around January 2026 for the trailer hitch wiring harness on my 2023 Hyundai Tucson Hybrid. For 6 months the local dealer told me there was no fix available from Hyundai. I finally received a notice informing me that parts were now available and to bring it in to dealer for repairs. I took the vehicle in for recall repairs on May 27, 2026. Instead of repairing/replacing the wiring harness, Hyundai removed the entire wiring harness making the trailer hitch which I use for my business inoperable legally. When I noticed the wiring harness missing several days later, the dealer said that was Hyundai's "fix" for the recall issue. I contacted Hyundai USA Customer Service who also told me that removing the wiring harness and replacing it with an inexpensive dust cover was the fix. They told me that sometime in the future there will be another recall to have the wiring harness replaced. In the meantime, they have taken my vehicle VIN off the open recall list, since it has been "fixed". Hyundai sold me a vehicle with a trailer hitch and now they have without my permission or prior knowledge disabled it.

The car has 57,000miles and needed a new transmission. Safety concern of the transmission failing while driving. There was a persistent and worsening rubbing noise once the car ran for 20 minutes or so. 4 visits to the dealer later, they confirmed the issue and Hyundai issued a warranty to replace the transmission with a remanufactured transmission. When I asked the dealer what happened, he said this was there 4th one in a few weeks. There were no indicator lights or anything besides the noise to indicate there was a problem.

NHTSA #11737934

Oil was leaking when we bought the car. By the time of the first service at the dealer (~7,500 miles), I had noticed the plastic underbody cover has some smeared oil that was making it past the plastic cover and fasteners. I had assumed they would catch any problems, but after the service they did not mention seeing anything, so I kept a closer eye on it. Brought it back about 1 to 2 months later (fall 2023) after dripping started occurring (oil was leaking faster, and making it past plastic underbody cover). They sent me home after wiping it up and telling me that there was no leak (there was clearly a leak, and I even showed them photos I had taken). I watched it for 2 more weeks, then brought it back in after taking more photos and showing them again that there was definitely a leak. They confirmed leak (after seeing the car for the 3rd time). Said it was the oil pan gasket, so they put a new gasket in. Earlier in 2024, started noticing oil leak again. Brought it back to the dealer's service department, and they said it's the same problem. They are planning to replace the oil pan this time to fix the issue, but have to wait on part. At this point, vehicle has been at the dealership's service department 4 separate times for the same issue that has not yet been resolved. Brand new car leaking oil that they are struggling to fix.

Engine would not accelerate after stopping at a store. Limped home at 15 mph. Engine light came on a few miles from home. Vehicle would not stay running the next morning and had to be towed to dealership. Problem was an injector that the seal had failed on causing the engine to flood with gasoline. Dealership stated they had seen multiple injector failures and replacement parts now have a different part number implying the injector has been redesigned. Hyundai refused to replace the other injectors as they had not failed yet (they did replace the one that failed). I went ahead and paid to replace the other three. I live in Montana. If I had lost acceleration going up a steep incline or in heavy traffic or car engine failed to stay on in remote area in sub zero temperatures it could have had detrimental consequences.

The automatic emergency braking system has activated on four separate occasions for unknown reasons or warning. Tapped the brakes and it disengaged. In three of the situations no vehicles or pedestrians nearby. One incident I was driving along a sidewalk when the braking system activated causing an abrupt stop

4/16/2026 at 1:35pm I was traveling north on Hwy 69 traveling +-45mph. Vehicle on my right in his lane and one vehicle in from of me about 50yrds. My vehicle auto applied the brakes and alarm indicating emergency collision to happen. A new minutes later (5 minutes) traveling in same direction same speed but NO cars on either side but one care approximately 100 yds in from and again the emergency collision brake and alarm took place

While driving my 2023 Hyundai Tucson PHEV with limited trim the Emergency Braking function activated for no reason at all. This has happened 5 times during the last 9 months and each time it was about the same conditions. Road was dry my speed was from 55 to 75 mph it was during daytime hours and no cars were in front of me or on either side of me. 3 of the times there was a car behind me that had to check up I guess because my brake lights came on. I reported the problem to the dealer and was told no other owner has ever reported than problem. Instead of preventing an accident the activation of the emergency braking system in this situation could have caused an accident with the cars around me reacting to my sudden braking at high-speed resulting in a chain reaction.

NHTSA #11632216

Driving on the highway when my car stopped accelerating when pressing down on the gas pedal. It was very risky to be driving on the highway without the ability to accelerate so we put our hazard lights on while we got out the highway ay the nearest exit and parked the car in a nearby parking lot. We were stranded about 100 miles away from home and had to have the car towed back home. Dealership confirmed that it was the fuel injector that was the issue and has been a known common issue for this type of vehicle.

NHTSA #11659099

FUEL INJECTORS FAILED AT 18523 MILES. Replaced both low and high injector on this cylinder 3 and then continued performance issues. Replaced all low injectors in Al 4 cylinders but did not replace higher injectors Stranded on Sunday on highway with no rental cars open except airport.

This is the SECOND time the vehicle has lost power and either had the engine die or stopped producing enough power to drive safely. The first time, the engine lost power to the put of not being able to maintain speed on a very busy highway during rush hour, forcing me to pull to the nearest side (left side of road) that had a narrow shoulder next to fastest vehicles. The most recent event (3/25/2025) took place in a parking lot. Engine was VERY rough at idle and when placed in reverse, it died. Could not restart for ~10 minutes, after which time the problem persisted. In both instances a tow truck had to take vehicle to dealership. In both cases the dealer indicated it was the fuel injectors causing the issues. No check engines lights or other dashboard light came on except for an indication to start the vehicle in Neutral. I used the companies app for the vehicle and no error codes came up. This issue resulted in no damage to persons or property, but could have if I wasn't next to shoulder in the first incident.

1. Component and Availability: The panoramic sunroof shattered spontaneously. The failed component was replaced by Myrtle Beach Hyundai, but I have documented the damage with photos, and the vehicle is available for inspection to show the remaining glass debris inside the structure and the damaged headliner. 2. Safety Risk: The sunroof shattered with a loud, gunshot-like noise while driving at 60 mph on a highway (I-95), causing extreme driver distraction and potential loss of vehicle control. Furthermore, a large amount of glass shards fell into the cabin and remains trapped inside the headliner. These hidden fragments continue to rattle, causing ongoing distraction and posing a risk of injury to occupants if they fall through the damaged interior fabric. 3. Confirmation by Dealer: Yes, the problem was confirmed by Myrtle Beach Hyundai. They replaced the sunroof under a "goodwill" gesture, although they initially claimed it was not a warranty issue. 4. Inspection by Others: The vehicle was inspected and repaired by the authorized Hyundai dealer (Myrtle Beach Hyundai). No police or insurance reports were filed as it was a spontaneous failure without a collision. 5. Warning Symptoms: There were no warning lamps, unusual noises, or any symptoms prior to the failure. The shattering occurred suddenly and without any external impact or provocation on January 12th.

NHTSA #11712996

VIN: [XXX] Component Failed: Panoramic Sunroof Type of Failure: Spontaneous Explosion/Rupture from the Inside Occurred: Saturday [XXX] at [XXX] Road Conditions: Smooth Road, Clear Day (No Rain or Hail), Temperature mid 80’s degrees Fahrenheit, No Other Cars on Road. Milage on Car: 19640 Initial Event: Driving on the road when passengers hear what sounded like a gunshot (no firearms present in the vehicle). Pulled over to the side of the road to check tires. Tires were okay but noticed the sunroof had spontaneously shattered. Initial Event Photo Indicates Rupture occurred from the inside of the vehicle and not an external force, but there was no access from the inside of the vehicle as the additional fabric roof prevented shrapnel from entering the vehicle. The glass continued to crumble as the driver returned the vehicle to the house for safety concerns. Patterson Hyundai dealer in Tyler, Texas, tried to submit warranty claim and subsequent appeal, but Manufacturer refuses to own manufacture defect. Drivers contacted glass repair companies in the area, and companies explained they had seen this occur several times before. Evidence: Initial Event Photo Indicates Rupture occurred from the inside of the vehicle and not an external force.

I was seated in the front passenger seat while the car was parked. I swatted a mosquito on the top of the windshield, just right of the rearview mirror/camera area. I did not use much force. The windshield cracked from the impact. The car is not available for inspection. The crack became considerably larger as we drove the vehicle. The vehicle has not been inspected by anyone yet, but will be taken for repair to an auto glass shop recommended by our insurer. There was no warning before the incident, and the windshield seemed to be in perfect condition. I called Hyundai to see if this was covered by the warranty, but they said no. I was shocked that such a small impact cracked the windshield - this seems like a defect to me

While driving on April 11, 2026 at approximately 1:30 PM on [XXX] , the vehicle experienced a loss of steering response while the roadway curved to the right. The driver turned the steering wheel normally in order to follow the curve. The steering wheel moved freely and felt normal. However, the vehicle did not respond to the steering input and instead continued traveling straight. As a result, the vehicle struck the curb on the driver’s side. The impact with the curb slightly redirected the vehicle, but steering response was not restored. The driver continued attempting to steer the vehicle, and although the steering wheel continued to turn normally, the vehicle did not change direction. The vehicle did not appear to lose traction and was not described as sliding. Instead, it failed to respond to steering input. There were no warning indicators, messages, or prior signs of a problem before the incident. The driver was able to bring the vehicle to a stop in a nearby turn area and arranged for it to be towed. After the incident, the vehicle was taken to a Hyundai dealership for inspection. The dealership reported no diagnostic codes and did not identify any issue with the steering system. No corrective action has been taken. 1)Steering system malfunction (column, shaft, rack, and/or EPS). Steering input was not transmitted to vehicle direction. Vehicle available for inspection. 2)Loss of steering control caused curb impact and risk of collision with vehicles, pedestrians, or objects. Could have resulted in serious injury at higher speed or in traffic. 3)No. Dealer could not reproduce. 4)Inspected by Hyundai dealer. No steering-related codes found. No cause identified. No repair performed. Hyundai Consumer Affairs case opened. 5)No warning lights or prior symptoms. Failure was sudden and without warning.

NHTSA #11699527

On [XXX], while driving a 2023 Hyundai TUCSON SEL, the steering wheel suddenly and completely detached from the steering column and ended up in the driver's lap. This sudden and absolute loss of steering control is a catastrophic failure of a primary safety system that placed the driver's life and potentially the lives of others in immediate and extreme peril. It was only due to sheer luck that the vehicle was brought to a stop without an accident or injury. Following the incident, due to fear and anxiety, the driver is now in treatment and has been unable to work. The vehicle was transported to Ron Marhofer Hyundai on the same day. The following day, the driver was met with a profound lack of respect and professionalism from the service advisor, Declan McCready. The driver and her mother were implicitly told they did not know what they were talking about and were treated with a profound lack of respect. The service advisor initially asserted there was no warranty coverage for the issue and that it would cost nearly $500.00 to fix. He also claimed his entire shop of mechanics looked at the car and found nothing was broken. However, the very next day, the dealership abruptly reversed their diagnosis and instructed the driver to get a rental car, stating they would now be fixing the vehicle under warranty. The repair order confirms the technician's findings: "verified concern steering column separated stopped bracket bent and separated replaced column housing operating normal". The vehicle had 14,479 miles at the time of the failure. There were no prior warnings or symptoms before the incident.

I parked my car on a driveway with a slight incline. After putting the car in park, I stepped out of the vehicle and the car rolled back into the street. I brought the car back into the driveway, again put the car in park and engaged the parking brake this time. The car rolled back out into the street again. Thankfully, the grandchildren were not playing behind the car and there was no one was parked behind me.

My vehicle has been in for service 4 times for the front brake rotors warping. The dealer/manufacturer is not able to fix nor diagnose the root cause of the issue. They have replaced the rotors twice and turned/resurfaced the rotors twice - all in 26000 miles. The dealer has all but given up on the issue - and has referred me to Hyundai Customer Care (Corporate) where I have logged a case. In my discussions with the dealer service manager - he stated there are "half a dozen" other cars he is aware of with similar issues. In online Hyundai owners forums this is also a "known" issue that apparently Hyundai either chooses not to fix or cannot determine how to fix.

I was driving on a highway at 75 mph, on a clear day, with perfect visibility and driving conditions and my automatic emergency braking engaged. I was on cruise control with no one in front of me for approximately half a mile. There were cars behind me, so I had to swerve into another lane to avoid being rear ended. There was a sequence of beeps. If there were warning lights or messages, I was too busy dodging to see them. There may have been a squiggly line that came up, but I am unsure.

Horn on vehicle consistently goes out. Either goes out entirely or the volume of the horn is below a safe level. This is a known Hyundai issue and Hyundai refuses to acknowledge it on this specific model, but has acknowledged it on different models. I Have had multiple repairs by Hyundai directly, and the horn consistently keeps going out. There are sometimes in dangerous situations where I need to utilize the horn to avoid an accident and warn other drivers of danger, and I am unable to do so, and it causes dangerous driving situations. This is a known defect on multiple Hyundai vehicles in this year, but the Tucson is one of the few vehicles they will not call a voluntary recall on and NHTSA needs to be notified about this and act accordingly as a regulatory body to protect consumers and people on the road.

The contact stated that the message "Limited to 20 MPH" was displayed on the instrument cluster. The contact depressed the accelerator pedal, and the vehicle failed to respond as needed. The contact stated that the engine was not revving. The contact pulled off the highway and into a parking lot. The contact turned the vehicle off and on, and normal driving was resumed. The contact stated that the failure was intermittent and was occurring while accelerating. Additionally, the contact stated that upon starting the vehicle in the morning, the vehicle would jump forward while still in park (P). Additionally, the contact stated that the horn had stopped functioning after the last loss of forward momentum but had returned to normal function a few days later. The vehicle was taken to a local dealer, however, the dealer was unable to duplicate the failure. The vehicle was not diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 26,500.

On Tuesday August 6th 2024 car was put in the shop for an automatic DTC notification/check engine light. Our car is less than a year old with less than 10,000 miles on it. Our car was in the shop for a full 5 days and was given to us on the evening of Monday August 12th with assurances that it was safe to drive. While in the shop, our car grounding pump and numerous fuses were replaced. On Friday August 16th, we received a jarring "Check Hyundai system. Stop Safely." message while driving a short distance. We were given roughly 5-10 seconds before the car braked and stopped, causing us to almost be rear ended from the car behind us. This put not only me and my passenger's safety at risk, but the safety of the cars nearby us at that time, at risk. We shudder at the thought of what could have happened if we were traveling on a highway or congested roadway. There were no warning lamps or symptoms that would have suggested this would happen. We received a tow to the shop early morning of August 17th and to date, the car remains in the shop. We are confident that the car will not pass it's upcoming inspection and have requested that the service dealership perform an inspection before they attempt to give it back to us. I feel strongly that we are not safe driving this vehicle. Our local Hyundai service dealership employees have implied that they feel a recall of this car is forthcoming because they have begun to identify this issue in many cars. Given Hyundai's recent track record with recalls, I am extremely concerned for my safety.

The Hybrid system has twice now failed on this vehicle shortly after starting it up. The second incident, I drove not even 300 feet, got onto a main, very busy road, and the system made a loud grinding noise, error messages came on the infotainment system and dash and the car stopped moving. It basically stalled without stalling. I was nearly hit from behind but thankfully a quick thinking pedestrian noticed and flagged the car behind me to stop. It took 5 minutes to get the car to reset and move but meanwhile it kept saying I need to hit my brake pedal to shift gears. I was in drive and I attempted to use my brake, to park, reverse, etc and nothing happened. As I attempted to drive to turn my vehicle around and get home it kept telling me I needed to hit the brake pedal to shift the vehicle (an automatic). This is the second time this vehicle stalled in three weeks and it has already once been repaired.

I was driving on the highway & my sunroof exploded. Glass was shattered & rained down on me & my occupants. 1/The sun roof - I have since vacuumed the mess, but it is still not repaired. Available for inspection if needed until I get it into the shop. 2/ I was driving 65 mph when the loud noise (phone gave a warning of decibal level not safe) - broken glass & glass 'dust' blowing on us / breathed in by us. The shock of it happening when surrounded by busy traffic on a highway. 3/I have made many calls into Hyundai to get it taken care of - they are not returning my calls. 4/I initially took it into a dealership (Ken Garff-Surprise) & they did not seem interested in inspecting - had a glass company reach out to me to replace the sunroof thru my insurance. 5/No warning at all.

Attempted to make right turn onto busy road. Tried to accelerate to move with the traffic, when the car would not go any faster then 20MPH. Could hear cars braking behind me. Pulled over to the side. Message appeared on speedometer, " Limit 20MPH" with green Speedometer. Shut the car off tried to find problem in the manual. Didnt find anything. Turned car back on, it ran normal. Took it to Hyundai, Fort Myers, Appointment, on 08/28/24. They diagnosed it as : "driver assist speed setting was turned on inside settings. Turned off setting, performed a DTC code scanning with no dtcs in any system. Attached stui photos, performed a 2 mile test drive with no further issues". I can only hope that the problem is solved. I do not recall turning on anything like, and wouldn't know how to, but I guess it is possible. Wanted to notify the NHTSA, in case there are other owners experiencing the same issue. Thank you for concern

After stopped at a red light, the light turned green and the car slipped into neutral when stepping on the gas pedal.

I was driving at normal speed and all of a sudden the vehicle accelerated to a high speed. Took to dealer with all the other issues and they could not create the problem. They are trying to blame it on me for have two sets of mats. Also navigation unit is not the correct unit in car. When I apply the brake to stop it seems as if the frame is creaking.

When pulling out of my driveway onto street, I lost acceleration. My vehicle would not go oer 35 mph and the RPMs were revving up too 5000 without speed moving. I tried changing the drive mode to fix it, that did not help. I pulled over,s topped the car and restarted and all seemed normal. This has happened 2 other times since I bought the car. The other 2 times was while i was on the interstate the engine stopped engaging and i could not accelerate. Both times the issue corrected itself by the time I could get safely out of traffic. This is a major accident concern as there is no warning before this happens.

NHTSA #11579684

On four occasions in the last five weeks, I have been driving at relatively low speed (20-30 MPH), and when I attempt to accelerate, the vehicle will not accelerate when I press the gas pedal. The tachometer shows the RPMs are maxed out, but the vehicle does not accelerate no matter how hard I press the gas pedal. I have to pull off the road, turn off the vehicle, and restart to fix it. I am certain I have not accidentally hit any buttons or switches each time. I have tried changing drive modes (eco/normal/sport) and using the paddle shifters and that has no effect. Cruise control is off, and no other speed limiting system is activated. There are no warning lights or indicators when this occurs. This is incredibly dangerous, as I am unable to get up to speed on a main road. A few instances led me to be unable to successfully merge onto a main road, which has led to me almost being rear-ended on one occasion, and the most recent instance I was in the left lane of a main road and attempting to pass a large truck and could not maintain speed. I was fortunate to come upon a slight downhill slope and was able to coast across the right lane and get off the road, but it was a near-accident. The dealer service center was unable to diagnose the issue, and therefore could not repair it.

This Hyundai Tucson was 3 months old when the transmission started to shudder and miss gears. I immediately took it in to Ken Garff Hyundai and the service advisor drove the car and said nothing is wrong with the car and that the transmission needs to break in and sent me on my way. The Tucson did it again while in traffic and the vehicle would not go and I had to put my hazard lights on and let the car struggle in changing gears to get it off the road. The car was towed in to Peoria Larry Miller Hyundai and this was documented by that dealership of the car shuddering and that they thought it was from my insurance plug in device. I explained that the car did it before the plug in. I removed the plug in device and the car continued to shudder. On [XXX] while backing out of my garage the car began to shudder while in reverse and i continued down the road while the transmission refused to change gears. It almost sounded aa if the car was in neutral and the car would on go no more than 3mp. I had the gas pedal floored and the car would not go. I reparked the car back at my home and called Hyundai for a tow. The tow came and the tow driver stated that the seemed as if it is in neutral as he drove it up on to the tow truck. After getting the vehicle to the dealership i was told from the service advisor that this is an ongoing problem with Hyundai's dual clutch transmission and this sounds like the problem.

Sitting at a red light the vehicle seemed to almost stalled then lunged forward about eight feet almost colliding with the vehicle in front of me. To my knowledge the vehicle has not been inspected by the manufacturer nor has the problem been reproduced by a dealer or independent service center. To my knowledge there were no warning lights, messages or symptoms. I am somewhat unfamiliar with this vehicle since I've only owned it for 5 days. I picked it up on 4-25-26.

On June 3, 2025, I experienced a terrifying and dangerous incident while driving my 2023 Hyundai Tucson Hybrid on a three-lane road at approximately 50 mph. Without any warning, the gas pedal became completely unresponsive, and the car abruptly decelerated from 50 to 20 mph. This sudden loss of acceleration was incredibly frightening, especially with vehicles close behind me that nearly collided with mine. There were no warning lights or check engine alerts. Fortunately, I was able to safely cross all lanes and pull over before having the vehicle towed to a local Hyundai dealership. I shudder to think what might have happened if this had occurred on a highway at higher speeds. This is not the first time I’ve experienced serious issues with this vehicle. In February 2024, at about 17,000 miles, I received an urgent alert recommending a system check. At that time, the car was revving while idle and would occasionally lurch at low speeds. The dealership had difficulty diagnosing and resolving the issue, and my vehicle remained in the shop for over a month before they ultimately replaced the oxygen sensor. Since then, the car has continued to lurch intermittently — for example, when backing out of a parking space or in stop-and-go traffic. In fact, approximately 10 minutes before the June 3 incident, the vehicle lurched several times while moving slowly in traffic. When the car began to lose speed during the most recent incident, I pressed the gas pedal all the way down, but it failed to respond at all. I believe the current issue may be related to the unresolved problems from last year and represents a significant and recurring safety concern. I’ve also read in Tucson owner forums that other drivers have experienced similar issues, suggesting this may be part of a broader, systemic defect. At this point, I do not feel safe driving this vehicle. I truly believe this car is a lemon. This vehicle is still at the dealership, but they have not given me any updates yet.

At dusk I was driving below the speed limit (40 MPH). I was at least 3 car lengths behind the vehicle in front of me when i saw the driver was braking because his brake lights came on and there was an intersection ahead with a stop light. There were at least two cars ahead of the vehicler I was behind. I braked but the car kept on going and appeared to accelerate. I was unable to stop the car with the brakes and collided with the car ahead. It was a sturdy vehicle with a strong bumper so I did not do much damage, if any, to the vehicle but my car requires 6,645.90 of repairs. No one was hurt and the air bags did not deploy. I was wearing my seat belt. There was no warning from ny vehicle that I was getting too close to the vehicle ahead and my car made no attempt to brake automatically. It was as though all warning indicators were not functioning. I have had two other incidents of the car surging ahead but did not report it because no one else was involved and I was able to correct the speed and I thought it was just my imagination.

2023 Tuscon Limited Gas - Multiple instances on Vehicle Forward collision warning system activating with alarms noted but no activation of emergency braking while sitting at stop light with cars in front and back that are not moving. Radio system going to show surround view and in some cases only front view even though at stop light. Biggest issue this weekend while taking a curve while merging onto another freeway the emergency braking system activated for no reason. First time occurrence. No one beside me or in front of me for some distance but did have someone behind me. It was a quick activation of the brakes and then release, I would say 1-2 second engagement. If had been longer and brought me to stop would of been an accident. I am taking the car to Westlake Hyundai to investigate this week and will report. Also having dealer investigate premature driver seat excessive wear. Car has 15.5K miles on it. I am concerned as this car is exhibiting same issues that my wife's 2018 Tuscon had that ended-up being successfully lemon lawed. I am also seeing way to many similar complaints and Hyundai needs to figure out what is going on with their emergency front collision sensing system and issue a fix or recall.

2023 Hyundai Tucson with just over 14,000 miles failed to accelerate. After completing a right turn the vehicle seemed like it went into neutral. A green warning light appeared stating limit 20 mph. I now know this is “limp mode”. Turning the vehicle off and back on seemed to resolve the issue. The vehicle was towed to the dealer. They found nothing wrong. I was told to take a picture of the warning next time. I was fortunate to not have caused an accident. This is incredibly dangerous.

For the second time in a year, I was pulling into a parking space and when I applied the brake, the car accelerated, seemed to be airborne and lurched forward. Though I firmly had my foot on the break, it would not stop until it hit a brick post about three feet away. This exact same scenario happened in July of last year. Then, I hit a stand of shrubs. Someone said, your foot must have slipped off the break and hit the accelerator. I said, “I don’t think so.” Yet, I took the blame for the accident, for I could not believe it was a car malfunction, nothing close to this had happened to me since I owned the car. Everything was the same in the last crash as in the first. This time, as soon as the car accelerated, I checked, and my foot was firmly on the break. There is definitely a malfunction in the car. The black.box Should be recovered and read by someone not associated with Hyundai. I checked on Hyundai Tucson Owners’ group on Facebook, and my incident has been reported by others.

Our 2023 Hyundai Tucson Hybrid developed an issue with the forward radar. At speed, the car produces a warning ding and then a warning message is displayed stating, "Critical Forward Safety functions are limited. Radar blocked." If the adaptive cruise control is engaged at the time of the warning, it immediately disengages, forcing the driver to quickly respond. If there is a vehicle in the adjacent lane to the right, the automatic braking may at times activate. It happens rain or shine, in good or inclement weather. We have cleaned the areas of the sensors without effect. One dealership has evaluated the vehicle twice and a second dealership once but we have been informed that there was no defect identified. I believe this issue to be a serious safety defect.

Unknown what fails. After driving approximately 30 minutes on a highway, car suddenly stops accelerating and bucks a bit as it slows. Must turn off car and turn it back on to accelerate again. Happens on the highway frequently. Very dangerous as there’s no way to accelerate. Only stop. It’s like it can’t find a gear and the engine revs. It happened 6 times during a 2.5 hour drive.

The contact owned a 2023 Hyundai Tucson. The contact stated that while his mother was driving at an undisclosed speed, she heard an abnormal sound emanating from an unknown location of the vehicle, after which the vehicle began to accelerate on its own. The driver attempted to stop the vehicle, but the brake pedal pulsated and failed to slow the vehicle, resulting in the driver briefly losing control of the vehicle and only coming to a complete stop after colliding with a utility pole. Both the driver and passenger side air bags deployed. No warning lights were illuminated. The vehicle was towed to a tow yard and deemed a total loss by the contact's insurance provider. A police report was filed, and injuries were reported. The driver and passenger were both transported to an area hospital by EMT and treated for injuries to the chest sustained from the air bags. The manufacturer was not notified of the failure. The failure mileage was 10,000.

The contact owns a 2023 Hyundai Tucson. The contact stated that while driving at slow speeds and attempting to park the vehicle, the vehicle unintendedly accelerated before the contact was able to regain control of the vehicle. The following day while driving away from a stop light, the vehicle briefly shuddered and was unable to exceed 20 MPH, prompting the contact to pull to the shoulder of the roadway. After restarting the vehicle, the vehicle returned to normal functionality. No warning lights were illuminated. The vehicle was taken to the dealer, who was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 3,000.

The ABS, ! Brake and Auto Hold lights activated. I took in into the Hyundai Joplin, MO dealership on May 2, 2024. They could not find any thrown codes and suggested it was most likely the "IEB Module" which they replaced and after doing so, the warning lights remained activated. As of May 22, 2024, they are ordering a new IEB Module to install (backordered into June). This seems oddly similar to previous ABS and brake problems of earlier models and makes me feel uneasy with the safety of this vehicle should they ever get it remedied.

New 2023 Hyundai Tucson purchased 9/9/2023 from Curry Hyundai in Cortland NY. On several instances of highway driving during the first 1,000 miles, on highways and at highway speeds, the forward collision avoidance system activated without any reason and applied the brakes at highway speed. This happened 6 or more times in only 6 or 7 highway trips during the 1,000 break-in period, and happened after the first visit to service for this problem, during which the dealer reset the system and sent me on my way, only to leave me driving a vehicle with the same, continuing defect. After the third service attempt, dealer and Hyundai have been unable to repair the vehicle (now with the dealer for over a week). Hyundai fails to even acknowledge its warranty or any other obligations to me, and all its communications show that it doesn't take these problems seriously, it has no standard process for dealing with them, and it offers basically nothing to the frustrated car owner. All its "customer care" department has done is check with the dealer, only to leave the problem with me for an unlimited timeframe.

As I was pulling into a parking space in a parking garage, the vehicle's engine revved, tires squealed and then the vehicle propelled forward on its own, without my foot being on the accelerator. The vehicle only stopped when it hit a support column and the wall of the parking structure. There was extensive damage to my vehicle and to the parking structure wall. My safety and the safety of others was put at risk due to the car accelerating on its own. The problem has not been confirmed or reproduced by the dealer, but we did take the vehicle to the dealer for inspection and they said they could not find anything wrong with the vehicle that would have caused the unintended acceleration. The vehicle has been inspected by the manufacturer, the insurance company and an investigator for Hyundai. Hyundai infomed us that they are not taking any responsibility for anything that occurred and that they will not share their investigator's report with us. There were no warming lamps or messages related to the problem prior to the failure. However, there have been other occasions while driving on the open road when the engine has revved on its own and I told Hyundai about that. In doing our own research, we have found that there are other 2023 Hyundai Tucson drivers who have had this exact same problem (unintended acceleration causing a crash) while pulling into parking spaces. Additionally, the air bags did not deploy during the collision and therefore the incident was not recorded by the EDR.

2023 Hyundai Tuscon - Very Low Milage approx 6500 Miles - while in a parking lot, The rear passenger Carrier ARM which holds the Control arm fully cracked causing the Control arm to fall off. This product failure is unprecedented as it was a total part manufacture failure. NO impact or under carriage damage was found, even upon Dealer inspection. I as the driver of the vehicle confirm that No impact, accident occurred, and luckily I was not on a highway when it occurred. This was caused ONLY as a result of Product Failure. My concern is that this may occur on the other wheel(s) as a product failure is often NOT a one- product issue, but usually a batch failure. So I am concerned for my safety and the safety of others on the road with this vehicle and product part. Another concern - this vehicle was manufactured during the covid era, and I am concerned about product failures as parts were difficult to get and may have been sourced without proper testing during this time). Kindly advise me on your findings, and if there is an inspection that can be performed to assure me that the car is safe.

I was backing out of my driveway, which is on a busy street. I waited for the traffic to clear. I backed out onto the main road, which I thought was completely clear, but a car came behind me and I smacked right into him. There was no beeping from my car, and the automatic braking system did not engage at all. The rear of my car, particularly the driver's side, was severely damaged. The other car's passenger front door was badly damaged. The side curtain airbag on their car deployed and their vehicle (Volvo station wagon) was not driveable. The emergency braking system frequently engages unexpectedly when I back out of my driveway, even when there is no hazard. The unexpected braking is oftentimes dangerous. However, this time, when I needed it, it did not engage. An outside diagnostic inspection was done on the vehicle, and showed "no event." If you saw the cars involved in the accident, it is clear there was a significant "event."

I am writing regarding a serious vehicle safety issue involving my 2023 Hyundai Tucson Limited purchased from on [XXX] with approximately 61,000 miles. About one month after purchase, during a drive from Pennsylvania to Florida in October 2025, the vehicle experienced multiple dangerous steering and collision-assist malfunctions in clear highway conditions. The first incident occurred in Virginia while adaptive cruise control and steering assist were active at approximately 70 mph. Within seconds, the steering wheel aggressively turned left and right, causing the vehicle to tip and nearly roll until the driver manually regained control. Later during the same trip, while making a normal lane change with the right turn signal activated, the vehicle falsely detected a collision despite no vehicle being present. The vehicle then veered left toward traffic and unexpectedly slammed on the brakes. Following these incidents, all assist sensors and automated driving features were manually disabled for safety reasons. However, the vehicle has continued intermittently triggering false collision warnings and emergency braking events with no vehicles present, creating additional near-accident situations involving surrounding traffic. I recently had the vehicle inspected by Hyundai after initially believing this may only be a calibration issue. Due to financial and scheduling limitations, I delayed service until this month, but I now understand this issue is far more serious and systemic. Two separate mechanics have advised me the vehicle has major safety-system malfunctions making it unsafe to drive. There are no reported accidents or braking issues on Carfax. I am also concerned this appears to be a widespread issue affecting this vehicle model, yet I received no notification regarding related safety concerns or recalls until conducting my own research. One mechanic stated“I’m surprised this car hasn’t killed you yet. I wouldn’t put my own kids in this vehicle."

My 2023 Hyundai Tuscon has 36000 miles. Started running rough with a slight noise. First noticed on Wed [XXX]. On Thursday [XXX] I went to start my car and it stalled. Finally after letting it sit a few minutes it started but only to have the SGI light flash yellow and stay yellow for the remainder of the drive. That day I made an appt at my local Hyundai Dealership in Brandon Florida. They kept my car. Fast forward, Monday September 15th I was notified that the car had lost a significant amount of oil. Car was inspected and free of any leaks. Tech stated because of the low oil & oil pressure the battery life was significantly impacted. I would need an oil change & new battery. Upon arriving back I came across an article stating that excessive oil consumption is common among these vehicles and the dealer wasn't even going to notify me of this issue. They were not honest and I want to file a formal complaint knowing that this is well known issue. I feel unsafe driving my children around and am upset that a recall has not been issued to fix this.

While on the road, the sunroof just shattered completely. In this instance, nobody was hurt as the cover below the sunroof was open and that caught all the glass pieces. The car is hardly 2 year old and warranty covered the repairs. The complaint is that Hyundai never gave a clear answer as to why this happened and what can be done to prevent it. There is no consideration of the passengers getting hurt and startled by this incident. Also no consideration for the time it took for the repairs, the dealership never gave a loaner and we didn’t know we could rent it and Hyundai would reimburse. I feel Hyundai cannot just say sorry and move on as there has to be a reason for this and we pay extra for having a sunroof. I am not satisfied with Hyundai’s method of dealing with customers who suffered bear of their own manufacturing.

1. Sometimes vehicle does not start. Only starts if battery reset button pushed. 2. Sometimes vehicle while moving has delayed braking after juddering. Only stops when car stopped and restarted. 3. Sometimes vehicle while moving suddenly revs, RPMs spike until car stopped and restarted. Engine revs but does not shoot forward. 4. Spookiest of all, while moving car suddenly stops accelerating. Pedal on the floor and it is coasting to a stop. When car stopped, and turned off, then it will work. Had we been on the interstate we would have died, These incidents were sporadic and occurred on and off during the month of April and May. Each of the above occurred numerous times to different drivers. Service at two locations were unable to ID. We sold the moving death trap to one of the Hyundai dealers who could find no mechanical problems with the vehicle. The vehicle was terrifying to drive. There are other reports on this vehicle of these issues ... which appear to be electronic. Hyundai has good engineers. They know what is causing this and simply do not want to replace a very expensive but obviously failing electronic control module.

As I was (very slowly) pulling into a parking place at a park near my home and I was braking to come to a full stop, the car suddenly lurched forward, jumped the parking place barrier, and hit a tree. The front end of the car was badly damaged and the airbag opened. I sustained injuries to my left hand and my chest, though nothing was broken. The car was towed to a body shop, where it has been declared not reparable. Photos of the car at the scene are attached. This accident seems to be consistent with reports/recalls of the Hyundai Elantra of unintended acceleration when releasing the brake. We did talk to police shortly after the accident but we are unsure if they filed a report.

I was driving straight when a vehicle coming from the opposite direction made a left turn without yielding, crossing into my lane. As a result, my vehicle collided with the other car at full speed. However, the airbag in my steering wheel did not deploy upon impact, as it should have. My injuries have been significantly more severe than they would have been had the airbag functioned properly. I reported this issue to the vehicle manufacturer, and they opened a case and conducted an inspection. During their inspection, they found that the airbag had since deployed. However, my vehicle was transported off a steep hill and moved to multiple lots before the inspection, any of which could have triggered a delayed deployment. Despite this, the manufacturer has refused to accept liability. Because the airbag failed to deploy at the time of impact, there was no buffer between me and the steering wheel. This resulted in excessive force against my chest from the seatbelt and direct impact with the steering wheel, leading to more severe injuries. There were no warning lights on in the vehicle before the crash, nor were there any recalls related to this issue at the time of the incident.

While driving 35mph on a 3-lane street in the far left lane, a driver of a Ford F-150 was in the center lane about two car lengths ahead, decided to make a right turn onto a residential street (as if he were driving a semi). As I got closer, the forward collision warning suddenly alerted and immediately initiated emergency braking system causing all 3 passengers to be thrown forward. I hit the steering wheel before seat belt caught me. I was not even within distance and he was turning in opposite direction of my lane. There also seems to be sensitivity issues with lane keeping feature as in Phoenix, there are never ending freeway construction with make-shift lanes not always marked well. On several occasions the steering wheel was jerked out of my hands because it couldn’t detect the lanes any longer. It has caused me to avoid freeways all together and has made me miss the exit off the freeway twice now. I thought this feature only activated during active cruise control, but apparently it does it regardless. Now I’m beginning to have problems with display going out at the worst times.

Driving down the freeway at normal speeds and my panoramic sunroof literally just exploded, raining tempered glass all over the interior of the vehicle while I was driving. No evidence that it was caused by any road debris, objects, nor falling objects from the sky. I wasn’t driving under a bridge and no cars/trucks were immediately next to me nor in front of me. Traffic was flowing at normal speed. I wasn’t injured but was certainly startled and distracted for a moment to gauge what had just happened. The dealer is looking into it. Claims it could have been caused by a rock. That seems to defy the law of physics and the glass actually look like it bowed from the inside out as if too much pressure was being applied to the glass.

Each dealership advised one of these problems, engine, brakes, rotors, tires, etc, although the vehicle was a few months old! I reported lemon l to Hyundai Customer service with 2 different attempts and they denied my lemon law and advised i should pay for anything not under warranty. Although the vehicle has a manufacture defect i will be continuing to attempt different dealerships to help my cause since i am endangering myself and everyone around me.

THE TRANSMISSION ELECTRIC OIL PUMP FOR THE IDLE STOP & GO SYSTEM (ISG) IN THE SUBJECT VEHICLES MIGHT HAVE BEEN ASSEMBLED WITH PRINTED CIRCUIT BOARDS (PCB) THAT WERE DAMAGED DURING MANUFACTURING BY THE OIL PUMP CONTROLLER SUPPLIER. A DAMAGED CAPACITOR ON THE PUMP CONTROLLER PCB COULD IMPACT ELECTRICAL OPERATION LEADING TO HEAT DAMAGE TO THE ELECTRIC OIL PUMP CIRCUIT BOARD, CONNECTOR, AND WIRING HARNESS. THE HEAT DAMAGE AT THE PUMP INCREASES THE RISK OF A VEHICLE FIRE IN ADDITION TO A POTENTIAL CONTROLLER AREA NETWORK (CAN) COMMUNICATION DISRUPTION FOR MULTIPLE ONBOARD CONTROLLERS. Thanks for your time.

When the vehicle was started the SRS light remained illuminated and when driving the vehicle over 40 MPH the abs, traction control, collision avoidance, and start-stop lights on the instrument cluster come on and remained on. The adaptive cruise control, nor the button for the start-stop deactivation work. The vehicle has just over 500 miles on the vehicle and is less than a week old.

Vehicle randomly keeps accelerating past the set speed when cruise control is set. Problem was first noticed in March. Have a video of the cruise set at 69 mph and the vehicle continued to accelerate to 87 mph before I disengaged it. Vehicle has been to two different Hyundai dealers for the issue but were unable to duplicate or find the issue. One moth ago were on a road trip and the cruise would accelerate to 8-10mph over the set speed on the cruise control especially after cresting a hill ,then the adaptive cruise control would brake hard when approaching another vehicle. 0

My son was backing out of a parking spot at a strip mall. He released some pressure on the brake and indicated that the car lurched backwards and even though he reapplied full pressure to the brakes, he hit the car at the curb resulting in damage to our Tucson, but luckily not the to the other car. The Rear Cross-Traffic Collision-Avoidance Assist system did not engage, but my son indicated that the rear distance warning system did beep. I am concerned due to the sudden acceleration/lurching incident my son experienced and this is not acceptable in any car. I ask the NHTSA to see if other Hyundai Tucson or Kia Sportage owners, especially with the Hybrid engine are experiencing this.

When driving the car and stopping at red lights, stop signs, or any other stops in traffic on roads and expressways, the car engine randomly dies and cannot restart between 3 and 10 mins. There is no warning when this is about to happen – the car engine simply dies and dashboard lights come on. There is no response from the car after shifting in Neutral or Park by pressing the start button with foot on brake. After some amount of time, the car will start. There is no warning before this is going to happen. The dealer (Patrick Hyundai) has inspected the car three times and has not been able to reproduce the problem as this happens randomly. They told me on my third visit to not bring the car back as they don't know what the problem is. The first time this happened was 4 months after I owned the car and has happened in excess of 6 times I now fear for my life when I drive this car. I was almost hit twice. I was stopped on a busy main street at a red light when the light turned green and all cars drove away and the truck approaching me assumed I would drive also but couldn’t because the car was stalled in the middle of the road. The truck veered away as last second to avoid my stationary car. The 2nd time was on expressway during traffic when stop and go driving was occurring and my car engine died again. As in previous case, vehicle behind me anticipated I would move forward like other cars but couldn’t and stopped inches from back bumper.

I purchased a new vehicle in February 2023. After a month and a half, I traveled to Washington DC on a pleasure trip. After my work/vacation trip when I am returning back to home all of the sudden, there was heavy smoke from the hood and eventually tried to turn off the engine but the car didn't respond, and when I tried to open the Hood in order to cool down the engine I see fire already in the engine. So, there was no intimation on the dashboard about the fire or not even an alert. Moreover, the engine didn't turn off even after trying to turn it off 4- 5 times. I was really worried about what would happen if the door locks stops working

I leased my 2023 Hyundai Tucson from your Authorized Dealership South Shore Hyundai in NY March 18,2003. I received the vehicle with 34 miles on the digital Odometer at approximately 1750 eastern standard time. At approximately 2030 eastern standard time with the vehicle at 62 mile on the digital Odometer. I was Driving with my family, which is made up of my wife, daughter 22yrs old and son 14 years old on the Wantagh Parkway South approximately location 40.740739,-73.544842 at the speed limit of 55 MPH. I began to hear knocking noise from the front of the vehicle that progressively got louder. Then immediately the check engine, brake, oil, key with car, battery, open doors, every light that the dashboard has came on. Immediately the whole vehicle lost power and I could no longer accelerate. The steering wheel got stiff and the vehicle had no response to brakes. The vehicle started stuttering.The engine died, RPMs at 0 and no response on the accelerator, brakes and steering. The vehicle would not start.I tried push start several times start the vehicle, remote start, app start and putting the remote close to the push start with no results. I felt helpless and in a very dangerous situation that this brand new Hyundai vehicle put my family and me in. My family’s life was at the mercy of a 62 mile brand new 2023 Hyundai Tucson Sel that I received less than 2 and half hours ago from a certified dealership South Shore Hyundai in NY. We were stuck in the left lane in the middle of the Wantagh Parkway south bound with nowhere to go with the median divider to my left and to the right it was a fully active lane of on coming traffic in order to reach the safety of the shoulder. My family and I had to cross a full active lane of on coming traffic to get to the shoulder safely. We were able to get to the shoulder safely.The safety hazards presented by this vehicle created is dangerous to America Families. Brand New vehicle should not suddenly shut off.Put the public in danger.

I just bought the car, it was brand new off the lot. The check engine light came on followed by every emergency warning on my dash. After this my power steering failed, I was able to move over to the right lane a bit, but that’s it. I tried turning the car off at this point and turning it back on, but it would not turn back on. I could not even put on my emergency 4 way blinkers. The car would not even detect the key at this point. Thankfully we were on a small, low traffic road and not the freeway or a major accident would have been inevitable.
