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 persisted after these repairs and have now escalated to uncommanded emergency braking. Date- and time-stamped video and photographs exist for multiple events. Two Hyundai dealerships have not identified a root cause. Similar phantom braking reports exist from other owners of this model year. We no longer consider the vehicle safe to drive.

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!

My 2022 Hyundai Tuscon came to a complete stop on the highway in Colorado twice in the last 2 months for no apparent reason. There weren't any obstacles or cars in front of me that would have caused the car to brake suddenly. I had passengers in the car and we were jolted forward. The air bags did not inflate and we were not hit from behind, but we could have been severely injured or killed. There are numerous "phantom braking" reports like this here on the federal safety agency site for the 2022 model as well as more recent models. Yet Hyundai has only issued recalls for the 2025 and 2026 models. How are you addressing this issue?

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.
