2020 Hyundai Palisade: false forward collision warnings

Filed Oct 26, 2025 · Driver assistance, Electrical · OH · crash · 3 injuries

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.

[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)

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.

Two issues: 1. Warning indicator comes on along with a warning that reads "check blind-spot collision warning system." these warning come on after driving for about 10 minutes, and come on even when no other vehicles are around or in blind-spot. Seems to be a faulty sensor. At time of writing this, vehicle only has about 500 (five hundred) miles. 2. Loud whistle/wind noise from coming in from driver side door. Occurs when traveling at approximately 50+ MPH. Seems like the door is not sealed properly, even though it is shut all the way. Loud noise could cause driver to be unable to hear emergency sirens, which could be fatal or cause traffic violations. With both issues the vehicle is in motion, on city streets and highway. The warning indicator with the blind spot warning will even stay on when the vehicle is pulled into a lot, comes to a stop, placed in park, and with no one around.

We purchased our 2020 hyundai palisade limited six weeks ago. Currently has 3000 miles. The blind spot collision warning system (bscw) has a malfunction and stops working after driving a few miles on both highway and city/country roads. There are no cars or trees/obstacles around the car when it deactivates. Restarting the car resets the bscw system, but it malfunctions again in a few miles. When the system is deactivated, we cannot turn off blind spot active assist--it gives a controller error. We tried shutting off the bscw system indicator in the heads-up display. That does not fix the problem
