2025 Hyundai Tucson: brakes engage by themselves (phantom braking)

Filed May 7, 2026 · Brakes, Driver assistance · PA

What component or system failed or malfunctioned, and is it available for inspection upon request? Automatic braking system brakes for no reason when I am not near any cars traveling at high speed or even when I am already at a complete stop or moving very slowly but not anywhere near hitting the car in front of me. This has happened multiple times since I leased this car in July 2025 and it seems to be getting worse. I had a 45 min drive home today and it happened about 7 times all for no reason. How was your safety or the safety of others put at risk? It slams on the brakes unnecessarily and the cars behind me almost rear end me. This has happened on residential roads and highways. Has the problem been reproduced or confirmed by a dealer or independent service center? I just called to take it in. They seemed to have no idea what I was talking about. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? not yet but I am taking it in asap Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? NONE

Phantom Braking due to Forward collision detection has caused one front end collision in snow and one rear end collision in a construction zone while I was slowing down. In one instance it was snowing and in one instance it was in a dusty construction zone slowing for steel plates.

I forgot to mention that with my two accidents while slowing down for traffic or a turn, that phantom braking happens almost every day now (it happened about 7 times in 4 minutes while I was on the highway, that's not exageration) Curves on the highway with a car diagonal to you in the center lane while you're passing, weird light reflection, falling snow, dust in a construction zone, anything. I can't drive with it on as it alerts to nothing. It's very scary to drive with it on, so now I have a useless safety feature that is really more like a death trap in the right circumstances, which will come.... Someone will be doing 70 on the highway, and their Hyundai Tucson will slam it's brakes on full tilt and it will cause injury and/or death. It's only a matter of time.

Subject: 2025 Hyundai Tucson - Persistent Phantom Braking Issue I am reporting a severe safety defect regarding the Forward Collision-Avoidance Assist (FCA) system on my 2025 Hyundai Tucson. Since purchasing the vehicle, I have experienced five separate "Phantom Braking" incidents where the Automatic Emergency Braking (AEB) engaged abruptly without any obstacles in the path. In the most recent incident, the vehicle suddenly braked from 30 mph to 20 mph] while driving on a highway. There were no cars or objects in front of me. This unpredictable behavior is extremely dangerous as it almost caused a rear-end collision with trailing vehicles. I believe this is a systemic software or sensor defect that misinterprets shadows or road signs as hazards. I request a formal investigation into this safety risk.

On March 16, 2026, my wife was driving our 2025 Hyundai Tucson westbound on Immokalee Rd in Naples, FL. She was traveling at a speed of 35mph, with no vehicles in front of her, but the Emergency Braking system engaged without warning and caused our car to come to a screeching stop. Several cars behind my wife's car had to avoid slamming into to our car. There are no bridges, overhanging tree limbs or other structures over the roadway. The weather was clear skies and sunny, and the time of day was noon. After this incident, we contacted the dealership from which we bought the car (11/15/25) here in Naples. We brough the car in for diagnosis but have not heard back from them. While there, my wife was approached by a dealership salesperson who overheard our story, and she implored my wife to "please report this incident...this phantom braking issue is a big deal..." Our salesperson did not admit to having heard of such issues, but he offered to buy the car back from us. We will wait to see what their formal evaluation produces and make a decision at that time. This could have been a deadly accident if the cars behind my wife had not avoided running into her.
