2022 Hyundai Tucson: false forward collision warnings

Filed Oct 8, 2026 · Driver assistance, Electrical · IN

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

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 visible issue. I restarted the car after a minute or so and it proceeded normally.

I was driving down the highway going about 60-65mph with cruise control and LKA on. I turned my blinker on to switch lanes, checked my blind spot, and moved over to the left. As I was doing so, a semi switched lanes from the left into the right (my new lane) right in front of me. The truck then slowed down a lot, and usually my Forward Collision Warning would say something if my Adaptive Cruise Control isn’t on (or is and I’m just going too fast to slow down) neither of those things happened. No warning. No automatic brakes. No slowing down. I tried to engage the brakes manually but nothing happened. I slammed into a semi at around 60mph because of 3 different system failures. Not only did I hit the semi at 60~mph, apparently my brakes didn’t work at all and I spun out until I hit the concrete barrier on the highway. If my brakes had engaged automatically, I could have slowed down enough to avoid the collision altogether. And if they had engaged manually I could have at least minimized the damage to my vehicle (and myself) because I wouldn’t have hit the concrete barrier as well.

The collision avoidance system has been going off randomly when there are no cars around, and also in the middle of traffic when I am more than two car lengths away from other cars; when I am on the highway driving fast and when I am on side streets driving slow, and even in my driveway. Additionally, some of the times that the warning system flashes and sounds off the car brakes and stops in the middle of the road. There is no pattern for when the incidents occur not are there any adverse road conditions. Roads here are flat and this has occurred during periods of no rain. Safety of myself my passengers and other driver is at risk due to the vehicle stopping for no reason. I took the car to the dealer, and they could not duplicate the problem and did not find any issues when checking the diagnostics.

I was told that Hyundai is aware of the problem but doesn’t know how to fix it so just take my car home and check back to see if they have a fix in a month or so.
