Warnings problems of the 2020 Hyundai Palisade

While idling at a traffic light on a busy city street all of the warning lights on the car went off and the car shut off on its own.

Rear sunroof exploded randomly.

I was driving through town at a low rate of speed (20-30 mph) with 2-3 car lengths between me and the next vehicle. I continued through light to next light. This distance was on an upward incline. After traveling approximately 500 ft, I noticed the traffic slowing in front of me and took my foot off the accelerator to start to slow down. This is when the car suddenly accelerated (instead of slowing down as would be expected when traveling up an incline), picking up speed quickly. The car's response happened so quickly that I was unable to swerve to avoid hitting the car in front of me. I hit the car in front of me that was slowing down at the light which then subsequently hit several other vehicles that were in front of it that were also slowing/stopped for the light. The front airbag deployed as a result of the collision, knocking my glasses off. The vehicle was still continuing in forward motion after the collision…. Traffic crash report states, “. . . [witness] went up to unit 1 [palisade], and the tires were still spinning…” as I was in shock after the collision, a bystander came up to the vehicle to turn it off and this is when the wheels/forward motion was completely stopped. This Palisade is equipped with forward collision avoidance assist (fca) system. There was no warning given nor did the vehicle attempt to slow down during the event so I believe that this system failed to operate which contributed to the collision. I also believe that there was a failure with the engine/electrical system, etc, and/or transmission that caused the system to suddenly accelerate while traveling uphill after I removed my foot from the gas pedal. The vehicle was totaled by my insurance company. They did say that they were sending an engineer to review the event data recorder. I have not seen any results from that nor do I have the vehicle in my possession as it was totaled.

On rainy days, the vehicle will start malfunctioning putting at risk my family's life and others. It appears to be an electrical problem according to dealer. It had 15 codes activated, all dashboard lights were lit and safety messages showed up, while driving. No power steering, emergency brakes were activated, transmission wouldn't change, a/c stopped working, temperature and tachometer were erratic. It is very scary because it happens while driving and an accident is imminent.

On February 2024, I took the SUV to lynn's Hyundai for an issue with a front sensor or the braking system - the problem is when you're driving at times very often in the streets, the vehicle will automatically cause the brake sensor to go off the dashboard with light up and the brakes will engage causing the vehicle to jerk hard and or stop at times and I have a huge concern that this may cause a serious accident. I was told by Hyundai service department, that perhaps were driving to close to other vehicles to cause this, but it happened several times when there are no vehicles or objects present. Apparently they had no interest in resolving this matter, they claim that the system test showed no duplication of said issue, vehicle was taken on a road test and they found no issues, the recall were all fixed, and I was called to pick up vehicle. I drove a few and the braking started again, so I pulled over and started recording to see if happens again and I was able to catch some of this problem on video. This has caused my husband to lose control of the vehicle causing him to hit a cone on the road. Your immediate help with this matter would be greatly appreciate.

The car will start but would not start moving. The adaptive system will turn on by itself and cause the car to stop moving forward.

When driving it gives warning forward collision assistance system disabled. Radar blocked. Warning stays for 3 to 5 minutes and goes away. But during that time when car is in cruise it is disabling the cruise mode. I took it dealer and said they need to change the camera module unit behind the rear view mirror and replaced it. But after coming out of dealer and driving for few miles again warning popped up and stayed for few mins. I took it back to dealer and this time they said avn head unit need to be replaced. I informed this to Hyundai as well and they created case with case number: 20602610. This started happening in July 2022 and I was coordinating with dealer to fix this. Still the issue is being worked on.

I approached the intersection slowly and stopped completely to turn right. There were a couple of vehicles in front of mine. I pushed the 'auto hold' button while waiting on the red light. A second later, I felt the car moving on its own and stepped on the brakes. The car did not stop and went forward and crashed into the vehicle in front of me. My vehicle did not stop after the initial collision and accelerated more on its own and went forward. I pushed the 'park' button to stop the car but it did not work and the vehicle kept moving forward fast and hit another car. It still kept moving fast until it hit other things. The car stopped after it went through a wire fence and hit a tree. The brake did not work at all. The car never stopped once it started moving on its own. Forward collision warning never came when it was approaching the first vehicle in front of mine on its own. The 'check engine' light was on for 3 days and disappeared on its own about 1 month prior to the accident. I tried to take it to the service center immediately but the earliest appointment I could get was in June. The service adviser at Hyundai service said there was nothing that they can do since the warning light was not on when we asked for a service check on 6/11/22.
