2025 Hyundai Tucson

I was driving inside a parking garage, making a right hand turn at a very slow speed (5 mph?), when my Hyundai Tucson Hybrid slammed on the breaks while in a right hand turn. There was a wall directly in front of me, perpendicular to the direction I was heading before I started to make my right hand turn. The wall was at least 15ft away. I was never at risk of hitting the wall. The breaks were applied after I was into the right hand turn. Most unusual, as I had the FCA (Forward Collision Avoidance) system turned OFF and I confirmed this by observing the symbol on my dashboard that indicated the FCA was off as soon as the breaks were applied. I don't understand how the car applied emergency braking going forward when the FCA was off.

I was driving on a clear day with no traffic in front of me, going approximately 35 miles an hour. My car abruptly took over the braking and suddenly stopped the car in the middle of the road. The cars coming from behind me had to swerve into the other lane to avoid a collision. It was terrifying. I contacted the dealer was told they had never heard of this happening and I probably had something stuck to the front of the camera. I said it wasn't the case and they said it was just an isolated incident and explained how I could disable the system each time I drive the Tucson if it made me feel better. There were no warning lights or other symptoms prior to this episode. They said I could bring it in and they could take it apart to look at it, but I would have to leave it for about 3 days, however they didn't think anything was wrong with it. Since they said they couldn't fix it, I didn't take it in and just disable it each time I get into the car.

The brake assist feature engaged when a second car cut a corner in front of me in Peoria AZ. The brakes engaged, and while waiting for the auto brake to release, a third care came up very fast behind me. I hit the gas in fear of being rear-ended. Apparently, in fear I simultaneously pulled on the steering column and the steering column pulled out beyond its normal range. The telescoping adjustment feature no longer works. The steering wheel is locked in a downward and elongated position. I took it to the local AZ Hyundai dealer for warranty repair and they said it was due to the Kirkland Hyundai dealerships failure to install a pin that locks the steering column in place after installing a lo-jack system. The column is not covered by warranty. There were no warning signs except the dangerous auto braking system, that caused a series of failures in the vehicle. This is the 4th time this braking system has almost caused a rear-end crash. The AZ Larry Miller Hyundai dealership suggested I contact the Kirkland Hyundai dealership in WA for damages. Damages to replace the steering column and replace the missing pin lock are nearly $3000.00 There are no pictures as the steering column has been reassembled but is bent and needs to be replaced.

I rented this vehicle for 5 days. In those 5 days, twice while driving on the highway (at 5-10 mph under the posted speed limit due to heavy traffic, dry and clear weather), I found it necessary to brake hard due to other vehicle traffic braking hard in front of me. When I had slowed down sufficiently and felt I had sufficient space between my vehicle and the one in front of me, I let off the brake pedal, but the "forward safety" feature continued to brake until the vehicle came to a complete stop nearly causing the vehicle behind me to hit my vehicle. To be clear, no accident occurred, but in one of those instanced the vehicle behind me was within ~1ft of hitting my rear bumper. Had the vehicle behind me not been able to stop in time, there would have been an accident, and because the brakes were locked by the computer, I could not have done anything to prevent it. After the second incident (on 2-15-2026), I looked through the vehicle setup information and found it is possible to disable the "forward safety" feature to prevent additional incidents, however, that setting can only be changed then the vehicle is stationary, and it automatically turns back on every time you start the vehicle.

The contact owns a 2025 Hyundai Tucson. The contact stated that while driving at various speeds, the Forward Collision Avoidance warning light was illuminated for approximately 30-seconds to 4-minutes. Additionally, while driving in the daytime, the message “Headlights Off” was displayed. The vehicle was taken to the dealer to be diagnosed; however, the diagnostic result was unknown. The failure had occurred four times. The vehicle was not repaired. The manufacturer was made aware of the failure and suggested that the dealer contact an engineer to go to the residence to inspect the vehicle. The failure mileage was 3,940.

The automatic braking that happens when the car sensor thinks you are too close to another car is dangerous. This has happened to me three different times when there were cars in front of me turning right. There was plenty of room and the car was turning so I was following, and it not only slams on the brake and makes you stop, but then it takes it a minute to reset before you can move again which then can slow traffic. I was almost rear ended two of these times. It is unsafe. You can manually turn it off, but you have to re set it every time you get in the car. I have seen many complaints about this occurring and causing people whiplash as well due to the sudden stopping on Hyundai sites.

Blindspot detection did not pick up car on my right side two times. Front collision warning is effected by the angle of the sun at certain times of the day. Dashboard dims randomly. Could be for a minute or much longer. Could dim on and off, or stay dimmed for over twenty minutes. Brought the car in twice for this problem. Claimed nothing found and tech reset the codes. Bought it in two weeks later, stating problem not fixed. Told them to check connection, suggested they might want to replace the cables, and its a known problem. Again, reset the codes. Only this time they fiddled with the dimmer control on the console and I can no longer adjust the setting.

The adaptive cruise control reduces speed when the car's driver camera "senses" that driver is distracted when in fact, this occurs frequently within even a 30 minute drive: it senses "distracted driving" due to wearing sunglasses, short stature making in cab camera have difficulty seeing eyes of driver, etc. This is a frequent problem in my car and a frequent problem in driver forums. This is unsafe when it slows car without warning and is stressful. Upgrades needed for safety.

Component or system that failed or malfunctioned: The electronic throttle control system and/or the powertrain control system malfunctioned, causing the vehicle to accelerate automatically and involuntarily. How safety was put at risk: The malfunction caused a collision with another vehicle and a structure. The failure placed the safety and physical integrity of two individuals at serious risk. Problem reproduction or confirmation: To my understanding, the issue has not yet been reproduced or confirmed by a dealer or an independent service center. Inspection of the vehicle or component: The vehicle and/or the affected component have not yet been inspected by the manufacturer (Hyundai), law enforcement, or insurance representatives, as an insurance claim is currently in progress. Warning lamps or prior symptoms: There were no warning lights, messages, or other symptoms prior to the failure. The incident occurred suddenly without any prior indication. During the event, the brake pedal did not respond.

I was travelling southbound on a main urban street. I was approaching an interesting with a feeder road to a major freeway. I was in a line of cars making a right hand turn onto this feeder. Just before I was about to start turning right, the Tucson Hybrid suddenly and unexpectedly smalled on the brakes and I came to a full stop. I was HIT FROM BEHIND. There was minimal damage to the car that hit me. My car had damage to some plastic components on the bottom of my rear bumper. Total cost to repair this damage was $785. No insurance claim was filed.
