What 379 owners told NHTSA about the 2023 Hyundai Palisade Hybrid Hev

I was stopped at a stop sign with my foot firmly on the brake and vehicles engine starting revving. Next was stopped at my mailbox with the foot firmly on the brake and engine started revving again. Next, I was pulling into my garage and had just taken my foot off of the brake and engine revved again, this time propelling me into my garage wall. I have a video of the car pulling into the garage and you can hear the car accelerate.

While sitting at a stop sign, I attempted to place my vehicle in Park. I opened the driver’s side door, but the car had not actually shifted into Park. None of the vehicle’s safety systems engaged when the door was opened. The car rolled forward with me partially outside the vehicle, dragging me until it struck a tree. This incident reflects a critical failure in the vehicle’s electrical/safety systems: •The transmission did not engage Park when selected. •The door-open rollaway prevention system did not activate. •The automatic front collision system failed to stop the vehicle. Because multiple electronic safeguards failed at the same time, this appears to be an electrical or computer system malfunction rather than driver error.

System that malfunctioned was the braking system Safety was risked because vehicle doesn’t stop as it should at low speed below 30mph. Safety of occupants as well pedestrians and other motorists affected. Problem can be reproduced although dealer refused to confirm. I am in the process of getting it confirmed independently. Vehicle and components not inspected by manufacturer, police nor insurance. Although I am in the process of putting an insurance claim in. The issue has been reported and confirmed by several other owners of same make and model and year. No prior warning of issue to it happening. The problem: At low speed below 30mph and braking simultaneously when going over rough ground (non slippery), potholes or in my accident going over a 6” drain to my garage, the ABS kicks in when it shouldn’t and the brake pedal vibrates and the vehicle lurches a bit. The result is that the braking distance increases significantly. I can reproduce the issue in particular roads areas. The accident I had involved when I was parking the car and the drain cover was dislodged at the entrance to the garage. I hit the brakes as usual but the brakes were ineffective and I ended up crashing into my refrigerator and freezer in the garage which took the full brunt of the impact and were damaged. I hardly had any brakes at all and the fridges took the full impact. Luckily it was at low speed. So only the front bumper got cracked and got damaged along with the fridges being fully crushed in. After the incident I was so shocked at what happened and couldn’t believe I lost the brakes so I found that several other owners of the same vehicle has had the same or even severe brake failures. I was able to replicate the problem fairly consistently in certain roads where it was slightly bumpy or rough. I didn’t want to try in my garage for obvious reasons. Furthermore the emergency brakes and collision warning did not activate either.

The sunroof glass exploded while traveling on the highway. The glass panel was closed shut about a minute before the incident. Small and large glass fragments entered the passenger cabin while traveling at highway speed. One large fragment caused a small laceration to the drivers arm. Another fragment struck the vehicle traveling behind and caused minor damage. Other large and small fragments landed on 2nd row passengers. There was no evidence of a foreign object or road debris causing this incident.

I purchased my vehicle from South Point Hyundai in Austin, Texas on [XXX], 2022. Almost immediately after purchase, I began having trouble with the vehicle’s braking system. In essence, the vehicle seems to inappropriately activate its ABS while braking over uneven surfaces (think-parking lots, speed bumps) in dry conditions. I have dashcam videos of at least three examples of this happening (from Aug ‘22 through May ‘24). I took the vehicle to the dealer for repairs that included the braking issue on or about [XXX], 2022, but the dealer claimed they were unable to diagnose and address the braking problem. There were no dash indicators or DTCs that were available. This problem continued to exhibit itself and was a matter of concern to our family, until the braking system’s failure caused a collision with a parking garage access gate arm on [XXX] 2024. This incident has created distress, and substantially impairs my family’s willingness to use the vehicle due to a now established safety hazard. We do not wish to put others in danger for a mechanical failure that we were told was non-existent when we tried to get it fixed in December of 2022. We have also been put in a tough situation because we do not have access to an additional vehicle for use while the problem is diagnosed at the dealer.

The contact stated that after the crash numerous warning lights were illuminated. The contact drove the vehicle to a local dealer who determined that the front passenger side tie rod was bent and that all of the collision sensors and the ABS module and the steering column sensor needed to be replaced. The contact was advised that the advanced collision sensors could not be reset. The right front passenger tie rod had been replaced. The vehicle had been partially repaired. The contact stated that the dealer could not determine why the sensors could not be reset. The vehicle sensor system had not been repaired. The failure mileage was approximately 5,800.
