Owner reports
Selected complaints filed with NHTSA by 2021 Hyundai Palisade owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2021 Hyundai Palisade. The contact stated that while driving at a low speed, the power steering failed, several warning lights illuminated, and the engine suddenly stalled. The vehicle was towed to a dealer, where the battery was replaced; however, the failure recurred two days later. The vehicle was then towed to an independent mechanic, where it was diagnosed with a failed alternator. The contact paid for the alternator replacement out of pocket. The contact stated that while at a complete stop recently, the brake pedal would travel to the floorboard when depressed, causing the vehicle to shudder. The vehicle would only resume normal operation after the accelerator pedal was depressed. The vehicle was returned to the dealer, but had not yet been diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 77,000.
Another vehicle t-boned my vehicle on the front left side. We were both traveling around 15 mph. As soon as he struck my vehicle, the air bags were deployed and the car instantly caught fire. The car was on fire before I was at a complete stop. I was able to pry the door open and crawl through a small opening after moving the air bags out of the way. I had to crawl into traffic to be able to escape the fire. If the door had been jammed more severely then I wouldn't have been able to make it out in time before the fire reached me. If my kids had been in the vehicle, then I would not have been able to get them out before the fire got to them. The police determined that the fire started at the engine. My insurance totaled the vehicle and then it was removed from the towing yard and taken to Montgomery. There were no prior issues or any warnings/messages before the incident.

The infotainment system that is included with the SEL model constantly disconnects from your cell phone. We did not know prior to buying this model that Hyundai had changed their vehicle packages so that the midrange does not have options for navigation or xm radio. This becomes a safety issue because instead of having my attention on the road as I should, I am attempting to reconnect my phone to use maps, and sometimes to fix the music, taking my attention off the road. I set everything up in my car prior to driving and yet the constant in and out of the connection causes me to readjust while driving. On long drives, navigation is essential to make it to the destination. Music is not an essential but it is extremely helpful to pass the time and also helps to curb the tiredness that comes with long drives. …
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. …
