2024 Hyundai Tucson Hybrid driver assistance problems

Filed Nov 6, 2026 · Driver assistance · FL

Multiple instances of my 2024 Hyundai Tucson Hybrid with the Smart Cruse Control "on" swiftly moving up on the car ahead on the highway then suddenly applying the brakes creating a collision risk from cars behind me. Speed would suddenly drop from about 70 to about 40 without warning. A second problem occurs when either this system or the Forward Safety System over reacts to a car in the next lane and suddenly applies the brakes in the same way. I previously brought the car to Jenkins Hyundai of Leesburg, fl because of similar problems several months earlier and they said it checked out OK and that they were unaware of a problem yet AI reports multiple incidents were reported and there is a potential class action suit ([XXX] vs Hyundai) under consideration. In my opinion, this is a very dangerous problem. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On Monday, 09/14/2026 at approximately 10:15am Mountain Time Utah State Route 36, North-bound. -- I was driving straight, approximately 60mph on dry road on a sunny day. There was no other traffic on the road either ahead, alongside, or behind me and no oncomming traffic. The Automatic Emergency Braking engaged, the emergency braking indicator flashed on the dashboard and the car slowed way down and then it just stopped engaging and the car rolled freely. I believe that the forward collision warning also sounded. NOTE-- this is not the first time this has happened to me. It has happened at least 3 to 4 times over the past two years since we leased the vehicle. I have asked the dealership service department to look at it, but they state that they can find no indication of any problem and that they have been unable to reproduce the event.

I was driving at a low speed (10-15mph) with a safe distance between me and the vehicle in front of me when the semi truck in front came to an abrupt stop. I reacted appropriately by pressing on the brake, however, my car accelerated into the vehicle instead. None of the emergency brake systems activated including the automatic emergency braking and front collision warning, which lead to my car driving into the semi-truck.

While driving my 2024 Hyundai Tucson Hybrid at approximately 20-25 mph approaching a red light, a sudden and total loss of brake power-assist occurred. Upon applying the brakes, the pedal became instantly rigid and rock-hard. Despite pumping the pedal multiple times and applying heavy manual foot pressure, the vehicle failed to stop, resulting in a low-speed rear-end collision with a stationary car stopped at the traffic light. No dashboard warning lights or malfunction indicators illuminated during or immediately following the event. After the collision, the vehicle's ignition was turned off and then restarted. Following this power cycle, normal braking functionality temporarily returned. The low-speed impact displaced an ultrasonic sensor in the front bumper. This intermittent electronic brake failure poses a catastrophic safety hazard to pedestrians and occupants if it recurs at higher speeds

Anytime I put it it in hands-free control on the highway. Even on the small highway normal strip the car swings left and right. And also when I'm getting off from the highway hello, Francis smells so close and there's a small bump the back of the car is sliding most of the time.

On Sunday evening [XXX] at [XXX] I was returning from Long Beach on the [XXX] home to Los Angeles, when I went under an overpass and my emergency braking system activated with an alarm and red arrow pointing to the left. There was no warning before this event. Then my lane assist stopped me from going over the line into traffic. A few minutes later the same thing happened again.

Issue has happened twice now, about 2 months apart. Driving at highway speeds, 60-75 mph, no other cars around, no reason for braking or stopping, the emergency brake comes up for a few seconds, abruptly slowing the car down for no reason. Very scary as the car starts to slow down from a high speed, very jolting. I've complained to Hyundai but they claim they are not aware of the issue and there are no codes the vehicle puts out so they cant investigate further without replicating the issue, but its random and you don't know when its happening. I've looked online and it appears there are quite a bit of 2023/2024 Tucson's that are having the exact same issue I am.
