2025 Hyundai Tucson Hybrid: false forward collision warnings

Filed Nov 6, 2026 · Brakes, Driver assistance · WI

On approximately three to four occasions, my 2025 Hyundai Tucson Hybrid has suddenly jerked or decelerated while driving, creating the sensation that the brakes were being applied unexpectedly. During there episodes, the vehicle did not respond normally to acceleration until the apparent braking released. A particularly dangerous incident occurred on XXX, when I was entering traffic after leaving a Subaru dealership in [XXX]. The vehicle unexpectedly jerked and failed to accelerate normally while applying the gas pedal. Another driver had to brake to avoid a collision with my vehicle. Hyundai Recall 302 addressing potential unexpected activation of the forward collision avoidance braking system, had already been completed on my vehicle on June 30, 2026. I reported these recurring incidents to the Zimbrick Hyundai service manager on XXX. The braking concern has not been diagnosed or repaired. I do not know whether these incidents are related to Recall 302 or another malfunction. However, I am concerned about unexpected braking or deceleration occurring in traffic and the risk of a serious collision. Attached are documentation confirming completion of Recall 302 on June 30, 2026 and email correspondence with Zimbrick Hyundai service manager documenting my report of the recurring braking incidents dated XXX.

I was going northbound on highway 77 in Bloomington, MN, switching lanes to get on an exit ramp to westbound 494. Another vehicle in front of me was also changing lanes but I had slowed down so we can switch lanes appropriately as we were both going at decent speeds and as I was braking and this car ahead of me crossed lanes, my forward collision warning activated and emergency braking occurred which inappropriately activated and caused me to abruptly stop while driving on an exit ramp on a freeway. Luckily the car behind me did not hit me but it was terrifying and scary and I had my two young children in the car. I have set up plans for updating the software for this vehicle with the current recall.

The forward collision system suddenly slammed the brakes hard to a full stop. This has happened multiple times in situations where there was no real danger(still safe distance with the car in front). I was fully in control, and there were no obstacles or sudden movements from other vehicles. Both times there was a car right behind me, and I was just lucky they didn’t hit me because they swerved into the shoulder. After the first 2 times, I mentioned it to the dealership and asked if there was any way to turn down the sensitivity so it didn't cause an accident and he said it's either all or nothing (which also isn't safe in case of real emergency). He recommended I file a complaint. I should also mention that I owned the 2022 Hyundai Tucson prior to this car for 4 years and never once had this occur. I did have it activate the front collision warning, but it never came to a full stop and allowed the driver to make the correct decision for the situation.

This is a very real safety concern. On multiple occasions, the automatic emergency braking (Forward Collision Avoidance Assist) feature of my 2025 Tucson Hybrid was activated in a completely unnecessary situation, endangering myself and drivers following behind me. If a car in front of me brakes suddenly, or a car merges quickly into my lane, which happens ALL the time as everyone has experienced, my car takes it upon itself to fully SLAM on the brakes without warning. Each time, it was in a situation where I could have easily slowed the car down incrementally so as to not put drivers behind me at risk of rear-ending my car. This feature can be temporarily disabled in settings, but it AUTOMATICALLY reactivates when the car is turned off then back on. This is a crash waiting to happen and it is unsafe to drive in its current state unless the feature is turned off manually every single time I start up my car. At the very least, there must be a PERMANENT way to turn of FCA.

I’ve had the car for 7 months. Three (3) times the forward collision avoidance (FCA) has engaged (full stop braking) when it was absolutely not necessary. All three times occurred while driving less than 30 mph on city side streets in Houston, TX. On the first and third occasions there was a car in front of me but that car and my car were both slowing down as we approached a red light. My car suddenly slammed on the brakes; I did not hit the car in front nor was I hit from behind. On the second occasion, I was making a right turn and the FCA slammed on the brakes and I was hit from behind. There was no damage to an older model car that hit me. My car had $785 in damage repairs. No insurance claim was filed. After incident #2 ( the one with damage) I adjusted the sensitivity of the FCA to have a slower reaction. It didn’t help as I had a third incident. My make/model will not let me permanently disable the FCA. After incident #3, I have been trying to remember to disable the FCA each time I start the car. I have not reported this to the dealer. I will be bringing the car to the dealer next week for this issue. The date below is for the incident when I got hit.

On 2 separate occasions, the forward collision warning system activated. On both occasions I was under control of the vehicle with my foot on the brake approaching a vehicle that had slowed while entering into a round about...I was approximately 10 feet from the car in front going about 6 mph. All of a sudden several warning indicators activated (audible and visual) and then out of nowhere, all four wheels locked and my car came to a skidding/juddering stop. I immediately looked in rear view mirror fearing I was going to get rear-ended. The vehicle in front proceeded to move on and I tried to get myself together and get moving. I was shocked that this had happened as it was totally unnecessary. I was completely in control of the vehicle prior to the activation.

No less than 6 times since leasing this vehicle the forward collision warning / automatic emergency braking has activated when it was not required as slow speed with vehicles behind me almost rear ending me. It is to the point where i no longer have confidence in using these systems and deactivate them when turning the car on. I have set the sensitivity to "Late" to decrease the incidence of this happening, to no avail. I am not the only complaint about this. This vehicle is not safe to use with this feature and should be investigated and a recall issued. Vehicle is going in for service on 5/29 for this issue.
