2020 Hyundai Palisade

1. What component or system failed or malfunctioned, and is it available for inspection upon request? "The tempered glass panel of the panoramic sunroof spontaneously shattered while the vehicle was in motion. The glass exploded outward with a loud report similar to a gunshot. Yes, the vehicle and the remaining glass fragments are available for inspection upon request 2. How was your safety or the safety of others put at risk? The sudden, explosive noise caused an immediate distraction and startle response while traveling at highway speeds (approx. 70 mph), creating a high risk of a collision. Furthermore, glass shards fell into the cabin onto the driver and passengers, posing a risk of lacerations and eye injuries. Shards also blew out onto the interstate, creating a road hazard for following vehicles. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Not yet. The vehicle is currently being scheduled for inspection 4. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? "No warning lamps or messages appeared. There were no prior symptoms of glass stress, such as cracking or creaking. The failure was instantaneous and spontaneous with no prior indication of a defect."

Vehicle is consuming or burning oil at a high rate. While dealer has done an oil consumption test and claimed it was "within tolerance," I have on multiple occasions had the car start to shudder at 2,000 miles since last oil change only to find the oil wasn't even on the stick anymore. The symptoms go away when adding oil, on some occasions more than 4 quarts of oil need to be added to get the oil to "full" on the dip stick. Multiple independent service centers have noted how dirty the oil is and how little is drained on oil change. No warning lights have come on at any time, even when car is making grinding noises and shuddering with no oil. This causes a safety issue as drivers reasonably expect to go at least 3,000 miles between oil changes and the engine could seize in traffic. Owners are being tacitly asked to add oil regularly to keep the engine functioning properly.

I own a 2020 Hyundai Palisade. The vehicle began jerking while driving, particularly during acceleration and shifting, prior to reaching 100,000 miles. Over time the issue worsened, and the vehicle started failing to accelerate properly when pressing the gas pedal. There have been significant hesitations before the vehicle would move forward. This creates a serious safety concern, especially when merging into traffic or turning at intersections. The condition appears to be related to the transmission. The symptoms began while the vehicle was still under the powertrain warranty period. I am concerned this may represent a broader transmission defect affecting other vehicles of the same model.

I am reporting a safety concern involving repeated engine stalling while driving my 2020 Hyundai Palisade. The vehicle has stalled a total of seven times during normal operation. Most of the incidents occurred while slowing down or stopped at intersections and traffic lights. In these situations, the engine suddenly shut off without warning. I was forced to immediately shift the vehicle into park and restart the engine to continue driving. The check engine light did illuminate in connection with this issue. These incidents create a serious safety hazard, as sudden engine shutdown in active traffic increases the risk of rear-end collision. The loss of engine power occurs unexpectedly and without sufficient warning. The vehicle has been inspected, and I was informed that the issue may involve internal engine malfunction requiring major repairs. Because this vehicle has experienced multiple unexpected stalls in traffic, I am submitting this complaint due to the significant safety risk posed by sudden engine failure during operation.

The contact owns a 2020 Hyundai Palisade. The contact stated that the vehicle was consuming an excessive amount of oil. There was an oil-burning odor coming from the vehicle. There was a misfire coming from the engine before the vehicle stalled. The Auto START/STOP was activated while driving. The feature was turned off, but quickly reactivated. There were no warning lights illuminated. The vehicle was taken to the local dealer, who was unable to determine the cause of the failure. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 89,000.

The contact owns a 2020 Hyundai Palisade. The contact stated that while driving at an undisclosed speed, the second-row seats were inoperable. The contact also stated that the second-row seat belts failed to function properly, and the seat belt buckles failed to latch securely. The contact received notifications of NHTSA Campaign Numbers: 26V034000 (Air Bags) and 25V607000 (Seat Belts); however, parts for the recall repairs were not yet available. The vehicle was taken to the dealer, but was not diagnosed or repaired. The dealer confirmed that parts were not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the failure. The approximate failure mileage was 70,000.

We scheduled in advance and confirmed recalls to have seatbelts recall serviced. Lost the entire day waiting for the service department to tell me they did not have the parts. The recall was mishandled and communication was kept to a minimum regarding the service noone knew about not having parts until the end of the day, which was 7 hours after our scheduled visit. A full day of work was lost and we are risking our child in a car seat on one of the affected seats. .the air bag recall also affects our means of transportation as we are risking travel each day. The dealership has not been helpful.

August 2025: While driving down the road and approaching a light, I slowed down to turn and make a left. As I braked, all lights on the instrument panel lit up and the car completely turned off. After several attempts to start the car again, the car started. After taking it to a shop, it was determined that the car had consumed all oil, despite being within the recommended milage range for oil change. I filed a complaint with Hyundai, who emailed me to talk to my local dealership. I responded and have yet to receive a response to my communication, as of February 20, 2026. Hyundai dealership has told me that I need to fail three oil consumption tests (I have), complete a combustion cleaning (it has recently been completed), and fail one more consumption test before they can submit to corporate for a new engine. In the meantime, I have experienced my car shaking, the smell of burning oil, my car "jolting" forward while driving at sustained speeds, and a tailpipe that is completely black with 67,800 miles currently on the car.
