I do not understand how Hyundai can approve its required testing process, have the vehicle fail that test, and then deny the engine replacement resulting from those findings. This is unfair and raises serious concerns about how Hyundai is applying its warranty procedures.Hyundai’s published oil-consumption procedures establish a process for diagnosing excessive oil consumption and determining when further repairs, including engine replacement, may be warranted. I am requesting that Hyundai explain exactly what requirement my vehicle allegedly failed to meet and provide documentation supporting the denial.I am requesting that Hyundai reverse the denial and fully cover the necessary engine replacement under warranty. I also request a complete review of my maintenance history, repair records, oil-consumption test results, diagnostics, and the dealership’s submission. This vehicle has been properly maintained and has only approximately 80,000 miles. I purchased it expecting a reliable vehicle that would last many years. An engine developing excessive oil consumption at this mileage is unacceptable, and I believe Hyundai should stand behind its product and warranty obligations.
NHTSA complaint #11763426 — an unverified report by a vehicle owner.
I am reporting a potential safety defect involving my 2021 Hyundai Palisade Calligraphy AWD. The vehicle has experienced repeated engine and drivability problems and multiple breakdowns following replacement of the engine by Hyundai. The original engine developed excessive oil consumption and was ultimately replaced by Hyundai with a new engine. Following the engine replacement, the vehicle experienced numerous additional mechanical problems and repair attempts, including engine rattling/pinging, intake-manifold replacement, oil valve-seal replacement, multiple cylinder misfires, ignition-system problems and an ignition-coil failure. Most concerning are repeated incidents involving severe shaking/lurching, loss of engine power, stalling and failure to restart. During one incident following repairs, the vehicle ran extremely rough, stalled and would not restart after approximately 20 miles of driving and had to be towed back to the dealership. During another incident, the vehicle experienced heavy shaking on startup, stalled and had severely limited power. Diagnostic history showed misfires involving multiple cylinders. On June 29, 2026, at approximately 103,671 miles, I was driving at approximately 50 mph when the vehicle began to lurch and shake, lost power, stalled and would not restart. The vehicle had to be towed back to the Hyundai dealership. The unexpected loss of propulsion and stalling while traveling at approximately 50 mph created a serious safety concern because I could no longer rely upon the vehicle to maintain power in traffic. The dealership subsequently identified an ignition-coil short/failure and replaced an ignition coil. The vehicle has nevertheless continued to experience additional mechanical problems. The vehicle is currently again at the Hyundai dealership. It has generated diagnostic code P0430 for Bank 2 catalyst efficiency below threshold, and Hyundai has recommended replacement of both catalytic converter/manifold assemblies. Th

At 16 thousand plus my car was at a stop light and stop/stalled/shut down what ever you want to call it. The auto stop was on but this was not the problem. I physically had to restart my car in traffic. The next time I experience this was at 20 thousand plus. We were in the hospital parking garage and the car again stop/stalled/shut down and I physically had to restart it again. This time I was driving with the auto stop off. I have experience this again at 21 thousand plus. Again I was at a stop light. The auto stop was off. The car stall/stop/completely shut down again. Car had to be restarted while again in traffic. Hyundai had been notified of the stall/stops. This was the last time I was dealing with this problem and took it into Happy Hyundai in Libertyville Illinois. They had it for a week. They did run test, but the car was not giving any codes. Happy Hyundai did not run it over the weekend for on my bluelink I get notification. On Monday my husband called and told them to drive it because this is when we are experiencing the problem. Happy Hyundai drove it once. Tech was not able to replicate it. My husband also took Happy Hyundai to let it run. They let the car run. This is what happen when we were in the hospital parking lot. We were sitting. The safety of the person driving the car is at risk for a accident. There have been reports on they Hyundai facebook web sites of the car stalling while driving at speed. I carry my handicapped daughter in my car. This stall/stop becomes a worry some problem, not knowing when it is going to shut off again. This has caused me much anxiety. I don't even want to drive my car. This is a accident waiting to happen. Along with many law suite's. No dash board cluster lights were on when the car stall/stop. Car has been inspected by Happy Hyundai and is now going back per Hyundai Coporate wanting a tech to pull codes.

Upon returning home on 7/20/2025, I smelled a strong odor of gasoline. I looked under the car and saw that gas was leaking from a small hole on the (R) rear side of the tank. The hole was an approximately 1/16" . Due to danger of flammable fuel vapor and leaking gas I parked away from the house and put a temporary plug to stop the leak. I was shocked to find that the fuel tank was unshielded and made of thin walled plastic. There no warning indicators given prior to this incident. The vehicle has 12383 miles on it. Cause of the leak is unknown, possibly a poor mold casting of the tank.

XXX - approx 9:00pm - departed Copper and Sage restaurant enroute to the WigWam. After about 1/2 mile at 30-35mph, I slowed down to make a right turn. After completing the turn I pressed the accelerator to continue and the Palisade had absolutely no power. I pressed the pedal to the floor with no success. I was finally forced to pull over and stop the vehicle and place it in park. After doing so, the Palisade was able to return to operation with the pedal and for fear of another incident we drove home. 2nd Incident - 2 Mar 2026 - approx 1200pm. We were traveling west on XXX from [XXX] to [XXX] and began the ascent through the mountains going west towards XXX. After experiencing a steady grade upward approximately 6-7% at speed of 55-60mph, I used the hand shift paddle to downshift one gear to assist in the upward climb. Upon doing so, the Palisade once again died with no power at all. I pushed the accelerator pedal to the floor with no success of power. This incident could have been devastating as we were in the far left lane with many other vehicles behind us. I had no place to pull over to the left so I began to make my way to the right shoulder over 3 lanes very slowly under only previous velocity motion. We narrowly avoided being hit from behind numerous times and finally made it over to the right shoulder. After finally stopping the Palisade, I put the vehicle in park and it returned to operation with the pedal once again. We then carefully pulled out off the shoulder and the Palisade operated normally until we arrived at our destination.

We lease a 2026 Palisade with only 4k miles. Several weeks ago I was going through a toll plaza, car would not accelerate after slowing down, as if it was in neutral. All of a sudden it kicked into gear and car lunged forward. 10 min later at a traffic light car failed to accelerate after a complete stop. Press the accelerator sluggish response, then kicked back into gear. Very Scary. I pulled over and notified the dealer. Then set an appoint. Dealer did a diagnostic, found no issues, could not replicate problem on test drive . Everything was fine a few weeks. My son took the car. Had the same exact issue with vehicle not accelerating. Then kicked into gear really hard and vibrating. This was scary for him because he was in a parking lot. Luckily there was no accident as a result. However, this time an error code (check engine light) came on and the Hyundai app showed a DTC CODE- P001600 (powertrain / engine). Car was immediately taken to dealer on May 28th 2026. It is now Jun 11th. Still no time frame for fix. The THINK it a software issue and Hyundai is still "working" on a solution.

While driving on my 2026 Palisade Calligraphy over last 6 months I lost all throttle/ gas response to engine on 12 separate occasions.The 3rd incident nearly resulted in serious crash in 55mph traffic. Went to dealer next day on 11/15 ref# 41788829 service found no codes, reset system and recommended a flight recorder to help diagnose. Filed with NHTSA on 12/3 after next incident ref # 11702738. Requested flight recorder multiple times with dealer and Hyundai case manager and after multiple visits, diagnostic drives and component replacement on 1/20 and 2/23 the dead throttle continued. On 4/7 I was finally issued recorder and captured 3 incidents of the problem that could not exist within 2 days. Dealer acknowledged problem and says they can not fix without help from Hyundai engineers. Hyundai will not buy back and tell me to go back to dealer for resolution. Dealer claims to have submitted all relevant info to Hyundai but will not produce requested paperwork to me for most of visits (illegal? ). I have been assigned 3 separate case managers who try to assign new case #42539227 and separate it from initial ref # 41788829 while denying buyback with documentation they refuse to share. I am driving an unsafe and dangerous suv with 3 clearly documented Hyundai flight recorder incidents and acknowledged safety issue.
NHTSA complaint #11742563 — an unverified report by a vehicle owner.
purchased a vehicle that has experienced ongoing mechanical and safety-related defects, including excessive oil consumption, seat belt malfunctions, and unresolved injector recall issues. Despite multiple repair attempts by the dealership, the problems continue to persist and have not been permanently corrected. These defects substantially affect the vehicle’s safety, reliability, value, and everyday use. The dealership and manufacturer represented the vehicle as reliable and safe; however, the repeated failures and unresolved recalls suggest otherwise. I believe it is misleading to continue selling or servicing vehicles with known defects that cannot be properly repaired. I have also learned that certain model years are no longer sold due to widespread malfunctioning issues that are costly for consumers to repair, yet I was not informed of these concerns at the time of purchase. I have made several attempts to resolve this matter by bringing the vehicle to the dealership for repairs, reporting the recurring issues, and complying with recommended service appointments. Despite these efforts, the defects remain unresolved, causing financial hardship, inconvenience, and concerns for my safety.

While driving, the vehicle in front of me stopped suddenly. When I pressed on the brake pedal it felt stuck and did not respond properly. The forward collision automatic braking system did not activate. This resulted in a crash. After the incident, the vehicle had fluid leaks and severe front-end damage and is not drivable. I am concerned there was brake system failure prior to impact.
NHTSA complaint #11735447 — an unverified report by a vehicle owner.
Hyundai's recent emissions software update (9C9) has disabled engine braking, creating a risk of brake fade on grades. The vehicle is no longer able to hold speed while descending grades, regardless of downshifting, forcing the brakes to be implemented to avoid excessive speed. This was never an issue prior to the software update and happened immediately after the software was installed. Instead of holding the vehicle with the engine (foot off the gas, and downshifting) the engine will continue to increase speed up to the point of approaching maximum RPMs. Further evidence of this behavior is that trying to use the engine braking no longer shows maximum MPG on the dash, indicating the software update is still feeding fuel to the engine with the foot off the gas.
NHTSA complaint #11735302 — an unverified report by a vehicle owner.
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.

Occasionally, the car's RPMs fluctuate wildly, and the engine stalls; the surges in RPM lead to sudden, abrupt acceleration, which poses a safety risk to me and my family. The dealership has been unable to resolve the problem.
NHTSA complaint #11733090 — an unverified report by a vehicle owner.
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.

The contact owns a 2026 Hyundai Palisade. The contact stated that the vehicle turned off on several occasions after the engine Auto START/STOP system was engaged. The vehicle was restarted and was taken to the dealer; however, the failure could not be duplicated. Additionally, upon starting the vehicle after the vehicle was refueled at a gas station, the check engine and several other unknown warning lights were illuminated, and the vehicle failed to respond while shifted to drive(D). The vehicle was towed to the contact's business. The vehicle was then towed to the dealer; however, the vehicle was not diagnosed because there was no warning light illuminated. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was 5,463.

The car will start shaking, can’t exceed a certain mpg, and does not speed up. The check engine light comes on. The car is available for inspection. I drive on the freeway and slowing down, and shaking can cause accidents. This a continuous problem.
NHTSA complaint #11726837 — an unverified report by a vehicle owner.
I am reporting a serious safety issue involving my 2025 Hyundai Palisade. The vehicle has repeatedly produced white smoke during cold start and has experienced loss of engine power while driving. Despite multiple repair visits (six times) to an authorized Hyundai dealership, the dealer repeatedly stated that the condition could not be reproduced and no repairs were performed. I provided video evidence of the white smoke and described the symptoms in writing at each visit. Shortly after the most recent service visit(12/22/25), within approximately five days, the vehicle displayed an “Engine Power Limited” warning message and a malfunction indicator light (MIL). When this occurred, the vehicle’s power was significantly reduced, making it difficult to maintain speed and creating a potentially dangerous condition, especially during highway driving or merging into traffic. This issue poses a serious safety risk because sudden loss of engine power can increase the risk of collision. The problem appears to be intermittent but recurring, and it has not been properly diagnosed or corrected by the dealership despite repeated opportunities. The vehicle has not been repaired for this condition, and the defect remains unresolved. The condition may be available for inspection upon request, and diagnostic data such as warning messages and onboard fault codes should be present in the vehicle’s system. The failure began with white smoke during cold start and later escalated to engine power limitation and warning lights.

Since purchasing the vehicle brand new in Oct 2021, all recommended services have been executed on time. (records to prove it can be provided if required) Aug 25, 2025. Mileage = 78,247. Full preventative maintenance including GDI Fuel Service and Oil change Nov 21, 2025. Mileage = 85,421. I am on a 2 hour commute home and the engine is stalling at every stop. Needs to be re-started each time. Pinging noise when accelerating. The car is brought into Parkway Hyundai in Wilmington, NC. Oil was below dipstick. This lack of oil causes the engine to misfire. I asked why the "low oil" light doesn't appear. I am told that he didn't know but the light only goes on when its completely out of oil. That doesn't seem safe at all. At this point, I am told by Service agent that this is a known problem with Hyundai and the recommend bringing the vehicle in for oil checks every 1,000 miles Dec 15, 2025. Mileage = 86,597. Oil check - Engine 0.4 quarts low after 1,000 miles. I am told it is "within Hyundai's range of acceptance Jan 2, 2025. Mileage = 88,463. Oil check - Engine 1.4 qts low after 2,000 miles. I am told 0.75 quarts every 1,000 miles is within the accepted range. Jan 22, 2025. Mileage = 89,487. Oil check - Engine 0.9 qts low after 1,000 miles. I am told 0.9 qts is within Hyundai's accepted range. This is unacceptable for a car to burn almost a quart of oil every 1,000 miles.

NHTSA complaint #11708539 — an unverified report by a vehicle owner.
While being inspected at the dealership, multiple fuel injectors (#1 and #3) were found to be leaking. This presents a severe fire hazard as fuel is escaping onto engine components. The dealership confirmed the leak and suggested replacing all six injectors due to potential systemic failure, but the manufacturer (Hyundai) is refusing 100% coverage. I have been without a vehicle for over a week, and this is a critical safety defect that could lead to an engine fire or stalling while driving.
