2024 Hyundai Palisade SERVICE BRAKES,FORWARD COLLISION AVOIDANCE

While driving at low speed and slightly uneven surface...approaching stop signs or intersections. The ABS system kicks in, shakes aggressively and can no longer control vehicle to come to a stop. This is a sporadic incident and has happened 3 times so far.

I just had my 5th occurrence with my new 2024 Hyundai Palisade where while braking at a slow speed, my abs kicked in and wouldn’t stop my car despite pushing the brake to the floor. Finally it abruptly stopped. In all situations, the road surfaces seemed to be slightly uneven or slightly bumpy. Each time this happened, I was traveling very slow and no faster than 10 mph. I’ve had my car for 2+ months and now has happened 5 times. This past time, I missed rear ending a vehicle in front of me because abs was aggressively pulsating but not stopping until almost hitting the vehicle in front of me.

When driving at low speeds over bumpy roads or obstacles like train tracks, seems like the ABS activates and the brake pedal turns very hard to press and the car wouldn't brake unless pushed very hard as the car keeps moving forward, not stopping. It's happened at least 4 times in 2 months. Braking capacity diminishes by 90% in those few seconds and if you don't know how to act and press the brake as hard as you can, the car won't stop.

I was approaching a stop sign at low speed. Road was a bit gravely and when I tried breaking the abs kicked in and wouldn’t allow me to break. A car was going and last second finally car stopped. It was so scary! Many times this keeps happening as I’m breaking if road has a slight bump or rocks the breaking system kicks in and takes over not allowing me to break. You hear the noise of the ABS taking over when it shouldn’t. I took car to hyundai service and they said they couldn’t “ replicate” the problem. I don’t know how they couldn’t because iI happens all the time!

Traveling in a slow lane of traffic. Brakes malfunctioned when I began to brake over broken/ not smooth road. Car began to shake hard and loud. Brakes locked but car was still rolling. I was unable to control the vehicle almost rear ending the car in front of us. I didn’t know what to do or how to stop us before we crashed. That’s When the car actually stopped everything went quiet and it seemed as if I got into an accident with myself. Because the car jerk hard and stopped abruptly. Called the dealership. To service the car. Told them what happened. Dealership said they cannot do anything about it. Told to express my complaint to NHTSA.

Brake or ABS failure when driving at a moderate speed between 10 to 20 mph over an uneven ground, slightly bumpy road, which makes the car shake and lurch forward while brake pedal becomes unavailable to press/hit . This has happened around 6 times within the last 10 months since the purchase, twice over a railroad crossing, and four times when passing over a sliding parking lot gate's track, dealer conducted a diagnosis but unable to replicate the issue, where they had driven the car not more than 5 miles within the limits of their parking lot. I opened a case with Hyundai Manufacturer America regarding the issue but they told me the same thing as the dealership did that they can't help me further because they couldn't replicate the issue.

I was pulling into my driveway [XXX] when I engaged the brake pedal pushing it fully down to stop behind my other vehicle. The antilock brake system seemed to turn on and the car did not stop. The steering wheel started shaking violently and the car went forward another 10-15 feet and I crashed into my other car, all while the brake pedal was completely down. We brought the car in to the dealership, Ettleson Hyundai in Countryside, IL, where they could not reproduce the event. They changed out the main governor of the ABS system anyway.
