2024 Hyundai Palisade

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.

The contact owns a 2024 Hyundai Palisade. The contact stated that while his wife was pulling out of a parking lot, the brake pedal was depressed; however, the vehicle independently accelerated forward and then came to a complete stop seconds later. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 700.

Two times my car has lost its ability to break, and when I try to break it feels like the break pedal was very hard to push down. The car was very lurchy but finally came to a stop when the breaks finally engaged. The feeling is like when you press on the breaks when you are sliding on ice. This leads me to wonder if it has something to do with the ABS system. The first time this happened I was pulling into a parking lot only going less than 10 mph. The 2nd time I was pulling out of a parking lot (again probably going 5-7 mph) onto a busy road and they failed to work. I almost ran into oncoming traffic and was very scared. I do not feel safe driving the car and had it towed back to the dealer. It is currently in the shop there.

At slower speeds, while braking or coming to a stop, if a bump or uneven surface in the road is encountered the car will violently shake. The steering wheel will shake left and right and braking action is lost. This can lead to dangerous situations at intersections or amongst other traffic as stopping distance will drastically increase unexpectedly. Based on previous reports this is likely caused by the ABS engaging at inappropriate times or performing in an inappropriate manner.

Car begins to shake if brake is applied when diving over uneven terrain. Acts like ABS is applied but car does not slow as it should. No lights or indicators flash when this occurs. Fortunately was able to stop before rolling into intersection as I was already traveling at slow speed. Dealer has not been consulted on this problem but Reddit indicates dealer cannot/will not fix it.

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.

When driving at a slow speed on dry uneven pavement, such as repaired asphalt around potholes, and the breaks are applied, the abs system kicks on and launches the car forward, sometimes in a series of occurances, before the car will stop. We brought the car to the dealership service department. They found no error codes and could not duplicate the problem, although it has happened at least four separate times when we ourselves have driven the car. The last time it happened (which is the date listed in this report), we ended up in a crosswalk before the car came to a complete stop. We have also found comments online from others with the same issue in Hyundai Palisades.

One month into ownership of my 2024 Palisade Limited AWD, I was approaching a stop light going ~20 mph and started to apply the brakes as I passed over some slightly bumpy ground. The car lurched forward repeatedly as the brakes were applied, bouncing forward in spurts rather than stopping and taking twice as long to stop than it should have; I was one foot from rear-ending the car in front of me despite beginning to break with plenty of time to stop - this is so far from how an ABS system is supposed to work and I've never experienced it in another car. Hyundai corporate has told me that, upon testing other Palisades, they have discovered that this happens in ALL 2024 Palisades. This is troubling for several reasons: 1) ⁠⁠The car exhibited an inability to effectively brake in a very common situation (braking when traveling at low speeds on slightly bumpy ground). Several people have noted this experience in Reddit posts; 2) ⁠⁠I have been driving for 25 years; I’ve driven other cars with antilock brake systems and have never been in a wreck. This is unlike any experience I’ve ever had in a car and it’s very abnormal / incredibly dangerous; 3) When asked to recreate the issue at the dealership, the head mechanic rode with me and said, “The car shouldn’t do that,” when it occurred with him the car. It was clear that he found it to be very concerning behavior. ⁠⁠Hyundai kept the car in the shop for 2 days shy of a month. At the beginning of the month, they apparently did not know that the 2024 Palisade behaved this way. Over the course of the month, they learned that this is how a Palisade behaves when driven over uneven ground at moderate to low speeds because they tried it with other cars they had on hand. This vehicle is prone to rear-end cars in front of it when stopping and also to bouncing out in the middle of an intersection when approaching a stoplight /stop sign. It will kill people of unaddressed. There are no messages / warning lights on in the car.
