The contact owns a 2021 Hyundai Palisade. The contact stated while driving at an undisclosed speed, the front row and second row seat belt buckles independently unlatched. The failure occurred on several different occasions. No warning lights were illuminated. The contact received notification of NHTSA Campaign Number: 25V607000 (Seat Belts) however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. A dealer was contacted and confirmed that the remedy for the recall was not yet available. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 50,000.

NHTSA #11745111

I am reporting a severe, life-threatening mechanical component failure of the front passenger seatbelt assembly on a 2021 Hyundai Palisade. While the vehicle was completely parked, stationary, turned off, and with the ignition keys removed, the front passenger seatbelt experienced a catastrophic static lockup. The occupant had reclined the seat, and the seatbelt accidentally became wrapped around their neck. The seatbelt was never inserted into its buckle receptacle, and the webbing was never fully pulled out to its maximum extension to intentionally engage the Automatic Locking Retractor (ALR) mode. Despite no rapid deceleration, extreme cabin angles, or full extension, the retractor assembly falsely engaged a permanent, one-way ratcheting lock. With every minor movement or breath by the occupant, the mechanism tightened further around their neck and completely refused to release tension. Because the physical obstruction of the occupant's body prevented the belt from retracting fully into the B-pillar to reset the mechanism, the occupant was actively choking. Time became critical, and the decision was made to physically cut the seatbelt webbing to prevent imminent asphyxiation. Because this life-threatening locking loop was triggered by a mechanical failure of a primary safety component—systemically linked to active safety recalls on this vehicle's pretensioner/seatbelt system—I am requesting a formal safety investigation. I demand that Hyundai Motor America issue a corporate variance to fully replace this cut seatbelt assembly at no cost. The failed physical components have been preserved for engineering inspection.

Front seat passenger seatbelt has come unbuckled while the car is in motion. Middle row seat behind the driver the seatbelt has come unbuckled while the car is in motion many times. I've contacted the dealership in Eugene Or several times and they continue to tell me they will have more in "next week" and they will call me to schedule. I've been waiting for many months. The seatbelts come undone so often in the middle row that I won't let anyone sit there. I've reached out to the customer service number and was also told the dealership will call me. I feel my car is unsafe since the seatbelts could come off at anytime. This is a known recall as of September 11, 2025. Recall number 25v607000

NHTSA #11734433

This vehicle is still using the defective style piston rings causing oil consumption of 1.5qts in 1000miles, With only 100,000miles. This has been ongoing since we purchased the vehicle with 94,000 miles. This needs to be issued as a recall to replace piston rings or the engine entirely. My valuemax level 4 extended warranty is refusing to repair the issue stating hyundai/kia has carbon buildup on the piston rings. This engine could run low on oil and cause a fire, or a engine shut down causing a crash.

NHTSA #11721125

The engine in my 2021 Hyundai Palisade experienced sudden loss of oil leading to engine failure. The vehicle had been regularly serviced and maintained at a Hyundai dealership according to recommended intervals. During multiple service visits, the dealership informed me the vehicle was low on oil. An oil consumption test was performed but the results were inconclusive. At approximately 99,500 miles, the vehicle developed an oil leak which the dealership diagnosed as a gasket issue and repaired under warranty. An oil change was completed at that time. Approximately 5,000 miles later, while driving, the vehicle began experiencing loss of power and rough engine operation. I immediately drove the vehicle to the dealership. The dealership later informed me the engine had no oil in it when inspected. There were no active external leaks observed at that time. The dealership stated that it is “normal” for this engine to consume up to one quart of oil per 1,000 miles. The engine now requires full replacement due to internal damage caused by oil loss. This situation created a safety concern because the vehicle began losing power while in operation. The failure occurred suddenly without warning indicators prior to the loss of engine performance. The vehicle had documented oil level concerns during previous service visits, suggesting a potential excessive oil consumption or engine defect. The failed engine is currently available for inspection at the dealership.

When driving at low speeds and going over bumps and speed bumps there is a thumping noise coming from the driver’s side rear. I’ve had the issue for quite some time now and there is a TSB on it for a faulty shock insulator. Between 2 different dealerships they have replaced it 3 times now and it’s doing it all over again. The last dealership has told me it is normal noise for the age and mileage of the vehicle.

I have a popping noise coming from the rear driver side suspension and it rides rough. I have been told by Hyundai that my rear shocks are leaking and from a different shop that my rear shock mount and absorber are causing the noise.

NHTSA #11700783

The 2021 Palisades started riding very rough and bouncy. I made an appointment and took it to Edmond Hyundai for the repairs. They initially said that the rear insulator-strut needed to be replaced and they would order them. It took 10 days to get the parts from Dallas and made another appointment to get it fixed. The dealership took 6 hours to replace only the insulator and kept it over night to do the 4 wheel alignment which they would not cover as warranty per the Service Manager but it was need. I picked it up the next day only to discover that only the insulator was replaced and was told that the service tech test drove the vehicle and it's fixed. I drove out and tested the suspension, it took only 1 mile and back it went to get fixed.

NHTSA #11677983

I own a 2021 Hyundai Palisade and have experienced a complete transmission failure that I believe Hyundai had prior knowledge of and failed to address. Before my warranty expired, I contacted the dealership several times to report transmission symptoms I was experiencing. I was told that because no diagnostic code had been produced at that time, there was nothing they could do. Eventually, my check engine light came on with a P0741 code — Torque Converter Clutch Circuit Performance. When I brought the vehicle in, the dealer flushed the transmission fluid, which came out dark and contaminated with metal particles. After running the vehicle, the fluid was still dark, indicating active internal damage already in progress. The dealership has now told me I need a full transmission replacement at my own expense. I am the second owner of this vehicle with approximately 105,000 miles. I have since learned that Hyundai issued Technical Service Bulletin #20-AT-005H-1 specifically addressing the P0741 code on the 2021 Palisade, instructing dealers to replace the solenoid and valve body harness. This repair procedure was never applied to my vehicle despite my early report of symptoms. I believe this is a known defect that Hyundai has failed to escalate to a recall, leaving consumers like me with thousands of dollars in repair costs for a problem the manufacturer was already aware of. I am requesting that NHTSA investigate this issue and consider whether a recall is warranted for the 2021 Hyundai Palisade.

NHTSA #11732982

The oil filter housing cracked and leaked engine oil at mileage 74992.

NHTSA #11705653

The vehicle experienced premature transmission failure, including torque converter clutch malfunction, hesitation, jerking at speeds between 30–35 mph and 50–60 mph, and drivability issues. Diagnostic indicators are consistent with widespread complaints from other Hyundai Palisade owners. This failure presents a potential safety concern due to unpredictable vehicle response, hesitation during acceleration, and reduced control during highway driving. Dealer / Manufacturer Response: Hyundai Motor America requires an authorized dealer to submit a warranty or goodwill claim for review. The servicing dealer, Reliable Hyundai (Springfield, Missouri), has refused to submit the claim, preventing evaluation and resolution. This issue appears to be a known defect affecting multiple vehicles of the same model year. I am submitting this complaint to assist NHTSA in identifying patterns that may warrant investigation or recall action.

NHTSA #11706552

The contact owns a 2021 Hyundai Palisade. The contact stated that on three separate occasions while driving 40 MPH, the vehicle lost power steering assist functionality. Several warning lights were illuminated, and the headlights and turn signals became inoperable. The contact stopped the vehicle and shifted into reverse (R); however, the rear-view camera failed to operate as intended. The vehicle was taken to the residence, but was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 63,400.

My sunroof was working perfectly fine a month ago. I opened it while i was driving to get some air 10/28/2025 and heard a cracking noise. I immediately stopped it. The glass was off the track and it would not close. It only opens a little then stops. Took it to Hyundai dealership and they said in their report"the tracks are cracked, glass came off the track and tracks are warped." This is going to cost me 3k and this was clearly a malfunction of the vehicle!!

NHTSA #11699054

I am submitting a safety complaint regarding the panoramic sunroof assembly on my 2021 Hyundai Palisade. The vehicle was purchased as a Hyundai Certified Pre-Owned vehicle in September 2023 with approximately 27,000 miles. The panoramic sunroof had only been opened approximately two or three times since purchase when the failure occurred. During normal operation, the sunroof wind deflector/visor malfunctioned and jammed inside the mechanism. This caused the pulleys and track assembly to bind and pull the glass panel out of position, damaging and breaking the sunroof track/mechanism. The dealer diagnosed the failure as a broken sunroof track/mechanism assembly requiring extensive repair estimated at approximately $4,000. This failure appears to directly match Hyundai Technical Service Bulletin 23-BD-003H-1, which acknowledges that the sunroof wind deflector may malfunction and damage the sunroof mechanism on 2020–2022 Hyundai Palisade vehicles. Hyundai issued this bulletin before I purchased the vehicle as Certified Pre-Owned. My concern is that this is a known recurring mechanical defect involving the panoramic roof assembly that could create a safety hazard if the mechanism jams, detaches components, shifts the glass panel unexpectedly, or causes the roof to fail while driving. The failure also caused the panoramic sunroof to become stuck open while driving. This created excessive rattling and vibration noise at highway speeds, which was distracting during vehicle operation and raised concerns about the stability of the sunroof assembly while in motion. Because the roof could not be properly closed or secured, the defect also exposed the interior of the vehicle to possible rain intrusion and additional electrical or interior damage. The sunroof was not abused or damaged externally. The failure occurred during ordinary use and after very limited operation of the sunroof since purchase.

NHTSA #11742363

Tried to open sunroof and it came off its track and twisted which caused some pieces to break. It is stuck in an open position. The vehicle has 144,000 miles so it no longer has any warranty coverage. We had to gorilla tape it down otherwise it could fly off while going down the road. I’ve read there has been many of the same incident happening to others.

NHTSA #11697732

I tried opening my sunroof and it made a clicking noise and is now stuck partially open. The dealership said that there is a set of Hyundai vehicles that are being covered by this malfunction but that my particular VIN isn't included. A Hyundai dealership is looking at it on Monday 03/17/2025 and is unsure if Hyundai will cover the repair since my VIN isn't included and I am past the bumper to bumper warranty. I only have the powertrain warranty left.

NHTSA #11647919

The vehicle suffered a structural "seam leak" on the pressurized oil filter housing. This was verified by an authorized Hyundai dealer (Dealer XXX, Invoice #XXX). The failure is a structural crack in the housing component itself, not a maintenance-related seal or filter failure. This defect causes pressurized engine oil to spray directly onto the hot engine block while the vehicle is in operation, creating a severe and immediate fire hazard. Additionally, the rapid loss of oil and oil pressure poses a risk of sudden engine seizure or stalling at highway speeds, which could lead to a crash. Despite being a known manufacturing defect in a critical engine component, the manufacturer has refused to address the safety implications or offer a remedy.

Vehicle experienced engine failure previously and received a Hyundai-installed replacement engine in February 2025. Replacement engine is now setting DTC P000A00 – Intake Camshaft Position Slow Response (Bank 1). Hyundai dealership master technician confirmed excessive variance between commanded and actual cam timing, indicating a VVT / cam timing failure controlled by oil and actuators. Hyundai is refusing to cover diagnosis and repair under replacement engine warranty and is requiring customer-paid tear-down despite fault originating within the engine assembly. Concern is for internal engine timing failure that may lead to engine damage or loss of power. This appears consistent with known Hyundai engine timing and oil control issues

NHTSA #11709745

My vehicle experienced a sudden and immediate loss of motive power due to a catastrophic internal engine failure, creating a severe road safety hazard. While driving and attempting to accelerate or merge, the vehicle exhibits extreme hesitation, severe misfiring on cylinder #2, and rough, unstable idling. This unexpected loss of drive power made the vehicle unpredictable and unsafe to operate under normal driving conditions, significantly increasing the risk of a crash. The vehicle is currently at the Hyundai dealership (Fox Ann Arbor Hyundai) for diagnosis. The dealer has confirmed and documented the following internal mechanical defects at only 86,000 miles: Compression loss in cylinder #2. Cylinder wall scoring and pitting. Evidence of blow-by and heavy carbon buildup in the combustion chamber. Misfire and rough idle. Oil consumption as a result of the cylinder failure. This failure is a premature mechanical defect, not normal wear. Failures of this nature (sudden loss of motive power due to internal engine defect) have been cited by NHTSA in other recalls and are known to increase the risk of a crash or fire. The manufacturer has acknowledged the defect by offering only 50% goodwill toward a repair, but this defect remains a critical, unresolved safety hazard that requires a full, safe engine replacement."

I have been having an issue with my 2021 Hyundai Palisade's engine oil consumption. It is constantly burning oil at a high rate, requiring me to purchase oil constantly. I had it serviced at Hyundai in Gurnee, IL. An oil consumption test was conducted. Hyundai corporate stated that my vehicle's engine was not burning oil at the required rate, which prompted an engine replacement. I reached out to corporate because the issue is persisting, but they never responded to my concern. This issue is costing me a significant amount of money, as I have to purchase oil without a remedy from Hyundai regarding my engine oil consumption. As a consumer, it's frustrating because I left without answers on an issue they definitely know about.

While driving the vehicle ahead brake suddenly. When I applied the brake pedal, it felt abnormally stiff/stuck and did not provide Norma breaking response. Th vehicle did not decelerate as expected despite immediate pedal input. At the same time, the Forward Collision Avoidance Assist system did not activate or provide any braking assistance. Due to the lack of effective braking, I was unable to stop in time and a collision occurred. The primary concern is a potential failure or malfunction in the braking system occurring prior to impact combined with the apparent failure of the automatic emergency braking system to engage. This created a situation where the vehicle could not be stopped under emergency conditions posing a serious safety risk

Pressed button to open glass sunroof and glass panel crookedly began opening with one side opening farther than the other until it stopped midway with a loud grinding noise. It stopped crooked in the tracks. It would not open. It would not completely close and the rear was left protruding above the roof line. There was nothing holding the back of the glass panel to the tracks. I could lift the back freely. A strong gust of wind or a passing truck could lift the panel. If the glass panel were to separate from the vehicle, a displaced panel could increase the potential of a crash or injury to other road users. I did not feel it was safe to drive it on the highway and took it to the Hyundai dealer where it sat until repaired on 4/7/2026 with redesigned deflector attachments, carriage bars and driving wedges. Hyundai TSB 23-BD-003H-1 describes this cascading failure of the defective air deflector breaking apart and damaging the sunroof tracks and specifies redesigned parts but fails to take in consideration that the glass panel is not held firmly in place once the connection between panel and tracks have failed. Prior to the sunroof’s failure I was unaware that a TBS had been issued. I had only opened the sunroof about a dozen times and received no warning of the failure. Subaru has issued a vehicle recall 26V346 which also results in a loose glass roof as a recognized safety risk including crash, fire, health, injury. Please encourage Hyundai to recognize the safety risk of a potential crash or injury to other road users of a loose glass sunroof as Subaru has and not as a warranty issue.

The vehicle would shut off when idling at lights or in reverse and have delayed acceleration after stops. It also would shut off when idling in park. I took it to the dealership summer-fall 2025 and they were too busy to investigate the issue because no alarms were present. The vehicle started doing the same thing and the check engine light came on March 2026. Now it has been in the shop for many weeks because of an fuel injector issue. The dealership service department says all 6 injectors need to be replace, but warranty won't cover them all. This appears to be a common issue with 2021 Hyundai Palisade vehicles and should be investigated for a safety recall.

I am writing to formally request reconsideration of Hyundai’s denial of assistance for the transmission failure in my 2021 Hyundai Palisade. I purchased this vehicle with the expectation that Hyundai vehicles are built to provide dependable transportation and that major components such as the transmission would last well beyond the current mileage and age of the vehicle. Unfortunately, I have experienced a significant transmission failure that has resulted in substantial repair costs. I have made every effort to properly maintain this vehicle and have acted responsibly as an owner. Given the relatively recent model year of the vehicle, I believe a transmission failure of this magnitude is unreasonable and may indicate a defect in materials or workmanship. I respectfully request that Hyundai review my case again and consider providing goodwill assistance, cost-sharing, or full coverage of the transmission repair. As a long-time consumer, I am extremely disappointed with the current outcome and hope Hyundai will stand behind its product. I would appreciate a written response explaining the reason for the denial and any options available for further review.

Whilst driving on the highway, the passenger rear quarter glass detached from the car and flew into the bushes on the side of the road. I heard a whistling sound coming from the inside of the car. I checked to see if one of the windows had been opened, yet they were all closed. I figured I would check the car when I got home to see where the disturbance was coming from. Yet while I was in the right lane, traveling at the speed limit of 70 mph, the passenger RR Quarter Glass Panel detached from the side of the car. The panel was lost in the bushes but most likely shattered on impact. This may be the result of a bad urethane bead when securing the panel during assembly.

On April 22nd my camera worked on my car but did not prompt warnings - I was in a parking lot and was backing up and tapped the car behind me. It is then that I noticed no beeping on getting close to the car. No damage to either car fortunately as they stated I was going ever so slow. On April 23rd got it in to the Hyndai dealership service department and there was another vehicle in there for the same issue I was told by them. WELL..... was told there is no recall. They replaced a harness I was told and final bill was $1126.30. NOt under warranty because my car has 113,000 miles. I would be glad to provide the final billing. I am reporting as there seems to ba an issue with this and I would hope that it gets addressed and if so would like my bill of $1126.30 reimbursed.

The engine oil system failed due to a persistent oil leak that was present from the time of purchase on December 16th 2024. The vehicle is available for inspection upon request and is currently immobile due to a completely seized engine. My safety was put at serious risk because the vehicle has no functioning low oil warning indicator to alert the driver of critically low oil levels. I was driving this vehicle regularly for work with no indication whatsoever that the engine was losing oil. A seized engine can cause sudden and complete loss of vehicle control which puts not only the driver but other drivers and pedestrians at risk. This failure occurred without any warning while the vehicle was in regular use. The oil leak was brought to the selling dealership, Auto Merchants Inc. in Plano Texas, for repair on January 6th 2026. They kept the vehicle overnight and confirmed it was fixed. The problem was not resolved as the vehicle continued losing oil. On March 3rd 2026 I discovered the engine was completely empty and added 6 full quarts of oil with no warning light appearing. I also contacted Hyundai consumer affairs and the Hyundai dealership directly who confirmed the manufacturer warranty had already expired at the time of purchase on December 16th 2024 and declined to cover the repair. The vehicle has not yet been formally inspected by the manufacturer or insurance representatives. The dealership serviced it on January 6th 2026 and claimed the leak was repaired however the engine seized on April 20th 2026 due to continued oil loss. There were zero warning lamps or indicators of any kind prior to the engine seizing completely on April 20th 2026. No low oil warning light appeared at any point during the 4 months I owned this vehicle despite the engine running completely out of oil on three separate occasions. The only symptom prior to full engine seizure was the vehicle sputtering when coming to a stop on April 19th 2026, one day before the engine seized completely

After emissions campaign 9c9, downshifting using paddle shifters on downhill grades, engine failing to maintain speed. Does not slow car down like it did before, seems like no compression. Fuel efficiency / emissions over traditional transmission braking, forcing drivers to use brakes more often to avoid high RPMs. Safety Risk: The lack of engine braking can lead to brake overheating or fade on long downgrades, lack of engine braking can lead to brake overheating or fade on long downgrades. Above is what Google found [XXX] ) when i put in some key words. Here is what i wrote to a [XXX] . my 2021 Hyundai Palisade Campaign 9C in your article about the 2022 having the same downshifting issues after the Emissions recall was done. Have you heard from other 2021 owners? I use the downshift for breaking/keeping my speed down to save the breaks here in the [XXX] , [XXX] , and [XXX] mountains. Does not function as designed. "Loss of engine braking" " High Engine Revving" Did go back to dealer and drove tech around lot. I called back later and nothing they can do. 5/12/26 Went to the dealer again, for an appointment. Dealer service manager said it working as designed. Bull, was not that way before. He said if i don't like it, trade in the car.. He also said that I can't compare the Palasade to the other cars that have manual shifting. bull. I said Why have them if they don't do anything... Tried to explain that I have been driving for over 40 years and have always downshifted every car. This was fine until the emissions recall. Got no place with the dealer. Contacted Hyundai Corporate last week, and they should be following up on Wednesday/tomorrow. 5/13/26 Left VM for Sales GM at Bowser today where i purchase the car.

While vacationing in Myrtle Beach with my family the vehicle alarmed and then progressed to critical failure of safety functions while traveling at approximately 55mph on Friday April 3, 2026. The vehicle was brought to Myrtle Beach Hyundai where it was eventually diagnosed and repaired as an Alternator issue that I have found to be common with this specific vehicle. The issues I have experienced with this vehicle go far beyond a typical mechanical concern. Over time, the vehicle has exhibited repeated electrical system malfunctions, including: - False blind spot collision warnings when no vehicles are present - Intermittent failure of the crash avoidance system - Loss of cruise control functionality tied to system faults - A broader electrical failure event that triggered multiple warning systems simultaneously Most concerning, these failures have occurred while the vehicle was in motion, creating an unpredictable and potentially hazardous driving condition. The loss and unreliability of critical driver-assist and safety systems directly impacts driver awareness and vehicle control, which raises serious safety concerns. Despite multiple attempts to have this diagnosed through the dealership network while under warranty, no definitive root cause was identified, and the issue has persisted. This suggests the possibility of a systemic electrical defect rather than an isolated component failure. Additionally, I have found that similar complaints involving electrical system irregularities and cascading warning system failures have been reported by other owners of this model, further supporting the concern that this may represent a known or emerging defect pattern. Given these factors, I do not believe this situation should be categorized as routine. Instead, it warrants review under the lens of: - Vehicle safety risk - Potential defect trend - Failure of critical driver-assistance systems during operation This vehicle has not been inspected by the manufacturer.

When I push on the brake the car starts to tug. Feels like it wants to turn off. Happened several times after I got a recall checked. 2 weeks ago same thing was happening and my car all of a sudden turns off. The lights on the dashboard turned on and the emergency brake engaged. I was able to turn the car back in after 3 tries. 6 days later I was driving 50mph and my car suddenly changes shifts on its own. It changed to neutral and then my car shuts off and again the dashboard lights turn on and the emergency brake engages. Again turned on after 3 times. Now the dealership is telling me that its my injectors. And that I had 10% fluid in my gas tank. That will not cause my car to shift gears and 10% is an excessive amount that would mess my car up

A week or so after taking the car in for an oil change, I was on the highway and heard a rattling sound coming from the engine. There were no indicator or warning lights from the dashboard. The car then stopped accelerating. It was on, and the accelerator increased the RPMs but the car did not move faster. I safely got home and checked the oil and it had less than a quart. There were no low-oil indicator lights telling me the oil was low. Separately, this week, while driving in the city, the engine again started making rattling sounds and completely shut off forcing me to pull off the road. Again, prior to the shut off there were no indicator lights. I was able to pull to the side of the road safely. I tried to restart the car and it would idle roughly befor the engine shut off again. After waiting 30 minutes, I checked the oil to see if the previous cause was the culprit, but this time the oil was still full. After 45 minutes, I was able to restart the car and drive home. I researched the issue and there are many complaints on Reddit about this for this make and model. Since the issue is intermittent and can't be replicated at the dealership, there is no fix offered. I no longer trust or feel safe driving this car, especially on highways.

While the vehicle was off and in my garage, the vehicle started on its own and was idling at an extremely high RPM. I was the only person home, the keys were out of reach on a key rack and had not been driven yet for the day. I walked into the garage and found my vehicles engine running at a high RPM and all the electrical displays within the vehicle were compleltely off with only the engine running. I retrieved my keys and my only thought was to start the car, which I did which then brought the RPM down to standard idle. I am extremely concerned as a vehicle idling in an eclosed garage poses extremely high risk to Carbon Monoxide.

The sunroof failed to totally open or close after an initial engagement. Further inspection revealed the sunroof wind deflector frame slides and shoes were broken, and cables were loose and out of position. Keep in mind, the sunroof has been used only a handful of times. After doing some research and learning Palisades had a history of exploding sunroofs, I worried that continuing to drive the car in a compromised condition (even a covered film to keep wind and rain out) would trigger the sunroof to do the same, putting my grandchildren in danger. After taking it to the dealer and having them confirm a TSB issued by Hyundai to address this very issue, I also learned it would not be a covered expense. Repair would run 3,000, a hefty consumer expense for a recognized flaw and safety hazard by the manufacturer.

I own a 2021 Hyundai Palisade Calligraphy with approximately 114,000 miles. The transmission had to be replaced at around 98,000 miles. Recently, before my next scheduled oil change (I had about 1,000 miles left), my vehicle suddenly began making a loud knocking noise and lost power. The dealer informed me that the engine may have blown. There were no warning lights, oil indicators, or overheating signs before this happened. The car has been regularly maintained and serviced with timely oil changes. This appears to be a premature engine failure possibly related to oil consumption or an internal defect, as many other Palisade owners have reported similar issues. Hyundai Consumer Affairs has been contacted, and a case number is being opened for review. I am filing this complaint to report a potential widespread engine problem and request investigation into 2021 Hyundai Palisade engine reliability and oil-related failures.

Magnetic chest clip will pop open after clipped. With one finger underneath you can entirely pop it open. Our original chest did the same thing, so chicco sent a new one and now just about a year later, this one also failed. Chicco is now sending a non-magnetic chest clip to remedy, however, this seems to be a further reaching problem. I am a CPST.

**Vehicle:** 2021 Hyundai Palisade Calligraphy, ~75,000 miles. Purchased February 2025. **Problem 1 - Forward Camera Failure:** The forward-facing camera system controlling lane keeping assist, emergency braking, and lane departure warning has completely failed. Dashboard warnings appeared in recent weeks including "Check Forward Safety system" and "Forward Safety system disabled" before total failure. This eliminates critical safety features designed to prevent accidents, significantly increasing collision risk. Camera unit behind rearview mirror available for inspection. **Problem 2 - Rear Shock Failure:** Rear shock absorbers have failed, causing excessive clunking and compromised vehicle stability. Rear suspension has been clunking since purchase in February. This creates dangerous driving conditions with reduced stability, increased stopping distances, and poor emergency handling. This is a known issue covered under Hyundai Technical Service Bulletin 22-22-001H. **Safety Risk:** Both failures create serious safety hazards - eliminating collision avoidance systems and compromised vehicle control/stability. **Professional Confirmation:** Local Hyundai dealer has confirmed both the camera system failure and rear shock absorber failure through diagnostic testing and inspection. **Components Available:** Both the failed camera system and rear shock absorbers remain available for inspection upon request. **Request:** Investigation and remedial action for these safety-critical defects, particularly given the rear shock issue is a documented manufacturing problem per TSB 22-22-001H.

1. When accelerating, the entire car shudders intermittently but especially after letting off of the accelerator and then reapplying pressure to the accelerator. 2. The entire rear suspension makes popping and clicking noises constantly and seems to "bottom out" when going over the slightest bump or road imperfection. It causes the vehicle to bounce excessively potentially causing it to "fish tail". Discussed with dealer during early scheduled maintenance with little to no concern by them.

In January 2025, during snowy weather, the windshield wipers on my 2021 Hyundai Palisade failed mid-operation and began making a buzzing noise. After 3–4 uses, they locked up and stopped functioning, causing a serious visibility issue. This occurred while driving, putting my safety at risk. This symptom directly matches NHTSA Recall 23V-180 / Hyundai Campaign 243, which I was told had already been addressed by the dealership I purchased from (Fitzgerald Hyundai in Gaithersburg, MD). I bought the vehicle used in April 2023, around the time this recall was active. I brought the vehicle back to that dealership in May 2025. They confirmed the wiper motors appeared to be binding and recommended replacement. However, they claimed the issue was not related to the recall and charged me a diagnostic fee of $209. Their service summary matches the defect described in the recall. I believe the recall fix was either never performed properly or did not actually resolve the underlying issue. This appears to be a recurring safety defect that puts drivers at continued risk.

On expressway traveling through Atlanta, changing lanes with plenty of clearence using signal at approximately 55 mph when suddenly alarm sounded and breaking system engaged bringing car to almost complete STOP. COULD NOT ACCELERATE and fortunately made it to berm area without causing SERIOUS accident. Turned engine off and restarted vehicle and continued on my way. Had vehicle checked at dealership and they said “all checked out and we found no diagnostics problem”. Also weren’t able to duplicate incident. I hope to God I AM UNABLE to duplicate the incident and cause fatalities including myself.
