2020 Hyundai Palisade

[XXX] - Driving from San Diego to Ventura County (home), my dash flashed something to the effect of "Emergency Braking System Malfunction" as my brakes were engaged while driving 65-70 miles an hour (no vehicles close in front of me or on either side). This was VERY scary and could have caused an accident if there had been vehicles closer. Usually when this system j=kicks in you get a Collision alert alarm, then braking initiates. There was no collision alert either. [XXX] - Took vehicle in and Hyundai said they could not recreate and had me take vehicle home [XXX] - Same thing happened on my way home from camping (emergency braking malfunction and brakes engaged while no vehicles around and nothing in front of me). This time the warning light (Triangle with "!" in middle and a number 1 lit up on dash and stayed on until I turned car off (I have a photo). [XXX] - Found this issue reported by multiple people on Hyundai online forum (emailed to manager at Alexander Hyundai). [XXX] - Took vehicle back in. Manager said he would check cameras as he believes this has happened before and they had to replace cameras. [XXX] - Dealership called and said can't recreate and want me to pick up car. Told them this is going to cause a bad accident and they will be liable. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On 1/24/2023 I was driving down the road from my home to go to work when, as I was going down an incline, my brakes started pulsing and I lost all braking ability. I drove thru a stop sign, into the intersection and was able to steer the car down the road. It was down a hillside. I was able to eventually stop the vehicle approximately a mile and half from where the brakes failed. I was instructed by the dealership to have the car towed to them so they could evaluate what happened. I did this. The dealership is trying to assess what happened. After 1 week, they replaced all 4 tires, did an alignment and replaced a leaking rear shock. The vehicle had 36,201 miles as of 1/24/2023. The dealership claims that the wear on the tires and the vehicle being out of alignment caused the wheel speed sensor to misread the speed and triggered the ABS to unlock all brakes. When this happened, all the warning lights for the braking system came on: ABS, Auto Hold, Traction Control, Forward Colision Avoidance System, Downhill Descent Control. I had nothing to stop me. Thankfully, no other vehicles came thru the intersection when my vehicle lost control. The dealership has, after a week, supplied me with a loaner vehicle. They are trying to duplicate the loss of brakes and all the lights that were activated when I lost my brakes. I also mentioned to the Service Manager at the dealership that I have repeatedly been asking the technicians to check the tires and to rotate the tires at our last few service appointments and had been assured the tires were fine and the tire rotation would be done. We normally have the tire rotation done every 7,000 miles due to the fact that it is an AWD. If this had been done as we requested, how could this happen? Wouldn't someone have noticed uneven tire wear? Our major concern is that when the brakes fail, you have no backup braking system in place. Is there something wrong with the programming for the electronic braking system?

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.
