I was approaching an intersection and it was a red light. There were rumble divets on the road to notify drivers to slow down. When attempting to break at 20mph, the brakes appeared to lock up and I couldn-??t slow down despite applying constant pressure to the brakes. I nearly hit the car in front of me and it was very dangerous. I-??ve never felt that before in a car and feel Hyundai needs to address the ABS system.

Car doesn't brake as expected over uneven surfaces (pot holes, speed bumps, divots) at low speeds (under 10 miles per hour). Instead of the car braking the ABS system kicks in causing a rumble and the car to continue to travel forward at its current speed. This in turn causes the driver to engage the brake completely to get the car to stop before rear ending a vehicle in front or proceeding past stop signs, red lights, and entering cross traffic.

I had this issue many times over the last couple of months. Every time the vehicle passes a pot hole or significant bump the brakes lock and I can't brake. No matter how hard I hit on it. This has caused many dangerous where I was unable to brake and almost hit another vehicle. It seems like the anti locking mechanisms or anti skid mechanism kick in and lock the brakes. I can hear a vibrating sound from beneath the car.

At a low speed coming to a stop sign on an uneven paved road the steering wheel shook and the brake pedal pulsed. I was unable to stop the vehicle in a timely manner. The outside conditions were normal and the pavement was dry. Luckily there was not a vehicle or pedestrian in front of me or I likely would have ran into them. It scared me and my daughter that was in the car with me.

Low speeds going over any uneven surface even slightly uneven causes the abs brakes to kick in and the car car shakes and unable to stop the car. Had happened multiple times this time I almost crashed into the car in front of me going 6mph because my brakes didnt let me stop and the road was fine just a a couple breaks in the pavement

While braking, hitting a bump causes the ABS to engage and disengage repeatedly causing a violent shaking in the brake pedal and steering wheel. The brake pedal goes soft and the issue was only stopped by pushing the brake pedal to the floor with extra force.

- Poughquag, NY, USA

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.

Slowing vehicle to prepare for a stop at Traffic Light I experienced a lurching forward after I applied the brakes for full stop.

- Green Valley, AZ, USA

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.

- Spokane Valley, WA, USA

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.

- Carthage, NC, USA

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.

- Oakland Gardens, NY, USA

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.

Hitting any bump/railroad track at even very slow speeds causes the breaks to not engage fully which has almost caused a crash on three different occasions. After researching this issue, it seems there was a similar issue that occurred with the 2023 Palisade.

- New Caney, TX, USA

I was driving in a shopping center parking lot and approaching a stop sign. As I was breaking and approaching the sign, I had to drive over a series of small potholes. As I went over the potholes, it seems the cars ABS system was engaged, and the car began to shake very dramatically, creating a more dangerous situation than needed to be. It seems others have had this problem as well, as I found online forums describing similar experiences driving over small rocks and bumps. It makes it harder to stop the vehicle before getting in the middle of oncoming traffic. There were no warning lamps or beeps to tell me ABS was engaged--it just started happening and only stopped when I pumped the breaks. I have not brought this up to the dealer yet and this issue has not been inspected yet, but I will be following up with the dealer as this is a brand new car. This is a link to a forum where others have experiences similar issues: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When I hit any kind of bump in the road while braking my brakes go soft and malfunction. It happens daily. Every time I brake and come in contact with any rough surface.

- Camino, CA, USA

Driving down cobblestone street approximately 15mph came to a stop sign and when pressing the brakes the abs kicked in nd the whole front end was shaking. I have never in 35yrs of driving have had this happen on a cobblestone street.
