2022 Hyundai Tucson forward collision avoidance problems

“Approximately one week after having my oil changed at a Hyundai dealership, I began experiencing intermittent collision safety alerts and multiple dashboard warning lights. On three separate occasions when I started the vehicle, warnings appeared for the forward and rear collision systems, along with multiple other sensor warnings and engine warning lights. During one incident while driving in traffic, the forward collision warning activated and the vehicle abruptly applied the brakes. I was nearly rear-ended as a result. I have taken the vehicle back to the dealership on two separate occasions. The dealership reported replacing a sensor, but the warning lights and collision system issues have continued to occur intermittently. I am concerned that the vehicle may unexpectedly apply the brakes again, creating a risk of a collision.”

“I had just started accelerating from a stop light at 715 am on a clear morning. I was not close to any other cars and there was no traffic entering. Without warning my collision warning came on and brought the car to a sudden stop. This is damgerous and I am lucky I was not rear ended”

“My wife was driving my SUV while I was a passenger. We were in the left lane, and put the left turn signal on while traveling south bound approaching an intersection to take a left turn (traveling approximately 3-5 Miles Per Hour and slowing) at the traffic light (traffic light was green). There was a car in front of us that had stopped waiting for oncoming traffic to clear and make the same left turn onto the same road as us. While traveling in this lane we hit a deep pot hole (not very visible while driving), just as we were approaching the vehicle stopped in front of us. When hitting the pot hole, our SUV seemed to leap forward a bit and when the brakes were applied to slow and stop, the braking system failed (appeared to freeze) and the brakes did not work, and because the braking didn’t work, our vehicle hit the car in front of us. Prior to and after hitting the pothole, no audible warning sounds or visible alerts appeared and no emergency braking was activated. The airbags in our vehicle never deployed. Our safety (my wife and I) as well as the safety of the 2 passengers in the other vehicle were at risk as we all could have been injured in the accident.…”

“Unintentional and unexpected activation of emergency collision or adaptive cruise control, causing the vehicle to stop and become immobile in the lane of traffic. I was driving down the interstate with the adaptive cruse control on and the lane keeping assistance on. These both were on for about 20 minutes as I was driving down the highway. There were no vehicles in front of or behind me for a quarter mile or so. I as all alone with nothing around me. All of a sudden it seemed like the collision avoidance system activated. The car came to a complete stop in the right lane of the highway. I tried to proceed and could see the emergency brake was on, the engine was running the car was in drive but it would not move. Flipped on the hazard flashers and traffic caught up to me while sitting in the right lane of the highway waiting to get rear ended. Vehicles were barely getting by at 70 MPH. The car would I pressed the accelerator and the car move d forward enough to get off the highway, this took a minute or two. Once off he highway, I could see the emergency brake would not release. I turned the engine off went out to inspect all the forward sensors. There was no…”

“On July 24, 2026, while driving on a marked city street with no vehicle, pedestrian, or obstruction ahead, the Forward Collision-Avoidance system on our 2022 Hyundai Tucson Limited AWD applied emergency braking on its own, three to four separate times, each lasting one to two seconds. Traffic behind us nearly struck our vehicle. My family was in the car. This is the latest event in a progressive electrical fault history. In June 2025, under warranty at 48,037 miles, a Hyundai dealer documented recurring multi-system warning cascades (forward safety, lane keeping, high beam assist, speed limit warning) and a failed auto start/stop system. The dealer's listed resolution was "battery voltage / replace battery"; their invoice records that no repair was performed. We replaced the battery at our own expense. The faults continued. In June 2026, the start/stop system shut the engine off at a red light and the vehicle would not restart, leaving us disabled in a live traffic lane. Power was only restored by cycling the hood release. Since then, TCM and ECU software updates and a battery harness replacement (our expense, approx. $1,200) have been performed. The faults…”

“Phantom braking while driving under a bridge. No cars around but Tucson warned collision while driving under a bridge and slammed on the brakes! This has happened multiple times. This fake safety feature is actually a hazard!”
