This is a known issue happening to Palisades and Hyundai isn-??t acknowledging the issue. A braking issue has been going on for a while but hadn-??t become a safety concern for me until this month. While braking but moving under 10mph, even less, the ABS system will engage without warning when driving over bumps or somewhat uneven road surface. This includes speed bumps. This has happened to me multiple times but never caused me to be in harms way until this month. I was braking for a stop light on a road with numerous small potholes. As I was slowing to stop, the ABS issue occurred. I braked as hard as I could but continued to get the push back/the automatic pumping action of the ABS system and continued moving forward. The car was shaking as well. I continued pushing the brake/attempting to get the brake to engage the entire time, and my car finally stopped, mere inches away from rear ending the car stopped in front of me. I was slowing at a safe distance and would have stopped at more than a safe enough distance away if my car had let me stop. Now I-??m deathly afraid of hitting a bump or some sort of uneven road when I need to stop and my car not stopping and hitting someone else, something else, or losing further control of the vehicle. No lights came on or any noises made to indicate a system was activated. My car also didn-??t warn me of a possible collision and didn-??t stop on its own, as it-??s capable of doing. It-??s as if the ABS issue overrode everything and my car just wouldn-??t brake. I-??ve never experienced anything like this with any other vehicle, driving on the same exact roads.

On Friday, February 14. 2025 at approximately 9:05 am I was leaving a parking lot to make a right hand turn on to a busy three lane road. Since this issue with the brakes has occurred three times previously I make it a point to drive no more than 10 mph in parking lots. The pavement was dry, then there was a 3 foot patch of thin ice, then the pavement was dry to the stop sign at the road. I pressed the brake pedal well in advance of the patch of ice and once the tires contacted the ice, the brake pedal pulsated harshly causing my vehicle to shake. This situation caused me to be unable to stop at the sign and I almost got broadsided. This is the third complaint I-??ve filed regarding this matter. This is the fourth occurrence of the brakes acting in an abnormal manner (since June 2024) and whatever is occurring is terrifying. The dealership claimed it couldn-??t replicate the issue and no warming sounds or lights appeared on my dashboard. I fear for my life, my spouse and children-??s lives, as well as pedestrians, bicyclists and motorists. Someone is going to get seriously injured or potentially killed because of this issue, therefore, I have to petition the agency to look into this matter in depth and hopefully open an investigation.

ABS system is engaging on gravel road when coming to a stop at 20-25mph. Brakes don-??t work and vehicle starts shaking. Hyundai dealership is saying there are no issues but this has happened periodically 4-5 times.

ABS shakes when crossing over different terrains. Car does not stop as fast as it should. I am afraid for the safety of my family and other drivers on the road if I can't stop. I have brought the car to the dealer several times since I bought it new and they say they can't recreate it. The last time, they recommended changing my brakes. I brought it to a private mechanic and they said it's not the brakes, it's the ABS. Then I come to find out that many people have the same problem and some have had accidents as a result of not being able to stop. There are 2 class action lawsuits calling for a recall. Please make Hyundai fix this issue before there are deaths on their hands.

As I was driving my car to work on 11/8/24 my pallisades brakes failed to work. As i was approaching a red light after stopping at a stop sign, It started to vibrate, like trying to grab traction, it did not slow down and continue the same speed until I almost hit a car at the light. What stopped the vehicle was the emergency sensor that started beeping as the car sensed it was getting close to the vehicle at the light stopped. In the last second the car stopped with the emergency brakes an inch away from a car accident. I called Hyundai and brought the car to the dealership where they kept it overnight and until the next day in the afternoon. I was told that this was a known issue to Hyundai and they have had several people complain of this same problem. Unfortunately they said there is nothing they could do and I would have to wait until Hyundai the manufacturer decides what to be done. They also called Hyundai corporate and filed a complain on my cars behalf. Now I am stuck with a car I am afraid to drive.

I was approaching a stop sign, slowing down to around ~20 mph, then gently applied the brakes. All of a sudden, the car stared to lurch forward and the steering wheel shuddered violently as the ABS braking appeared to kick in. As the brakes were applied, the vehicle kept bouncing forward in spurts rather than stopping and it took almost twice as long to stop than it should have. There was a vehicle in front of me and my vehicle was a foot from rear-ending that car despite me slowing in advance and attempting to brake gently. The collision warning system kicked in and I suspect that the vehicle stopped itself, even though I was firmly holding the brake pedal down. My wife experienced te identical situation a week later, so this is becoming very concerning. A quick search on the internet has revealed that many other 2023 & 2024 model year have experienced the same issues, and apparently Hyundai USA is aware of the issue, but do not have a solution to fix it yet.

Dear Sir, My car has brake acceleration several times.

- Yonkers, NY, USA

Driving on a gravel road (with small pot holes and bumps) down a slight hill caused my brake pedal to shudder making it impossible to slow to a speed I felt comfortable with. I had to remove my foot from the brake pedal and step on it as hard as I could to slow down. This is a serious safety defect and the issue needs to be investigated especially since many consumers have submitted similar complaints.

When driving at low speed (<25mph) over uneven terrain, such as bumps in road or small potholes, and applying brakes, the Anti-lock braking system will engage and causing vibrations in the brake and steering column and the car will not slow down. This is documented by a multitude of drivers: [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle would not slow when brakes were applied. Traveling under 20mph on dry, level, clear, straight surface. Brakes were applied and no response from vehicle. More pressure was applied, still no response. As vehicle approached another vehicle it issued the proximity crash warning and came to an abrupt stop just inches from a collision. It is uncertain whether the crash warning or the pressure on the brake pedal was ultimately responsible for stopping the vehicle.

A severe safety concern with our 2023 Hyundai Palisade, which has been present since the day we received the vehicle. When braking on uneven roads, the brakes jitter and stutter. This issue does not seem to occur on flat surfaces; however, it is always at lower rate of speed when roads have bumps. On three separate occasions, I have experienced a complete loss of brakes, and my wife has faced the same issue at least five times. When this happens, standing on the brakes does not trigger any response-?"there are no warning alarms, and the brake system completely fails. The potential to hit another vehicle or pedestrian, or veer into oncoming traffic, is very high, and in fact, I-??ve had to swerve into a curb (causing curb rash to the right passenger rim) to avoid a collision. Due to the severity of this problem, I no longer allow my wife to drive the vehicle. I have a appointment on 10/21 with McDonald Hyundai. I have noticed this since day 1 and regret that I did not act sooner! Upon conducting research, I discovered over 21 complaints on one website alone regarding the exact same issue. I am deeply concerned that the mechanics may not be familiar with this specific problem.

Under certain braking conditions, going over gaps in the road/bumps/railroad tracks and using the brakes, the brakes will lock up and stop working. The ABS seems to stop working, brake shakes hard and the car will not stop at times. Issue can occur at any speed, seems to be more common in lower speeds, under 25. Mentioned problem to specific dealership in Colorado and they did not seem to care about safety issue. Going to other dealership to have problem looked at. Appears to be an issue for certain 2023-2024 Hyundai Palisades in looking at online forums. Hyundai does not appear to have acknowledged this issue yet.

When applying the brakes at slower speeds the over-sensitive ABS violently activates causing temporary brake loss and shaking of the vehicle. This has been addressed at Hyundai dealership and symptoms were confirmed from the service advisor. I was told that this isn-??t normal operation per Hyundai. Regarding another issue. The transmission will shutter combined with 3-5 second delay when up-shifting during acceleration. I was told by Hyundai dealership that is also -??normal-??. If this is -??normal-?? then why has this concern just started developing. If this is normal, why hasn-??t this transmission done it from day one when we purchased the car. We are not happy Hyundai-??s attempt to sell us on this falsehood! These are definitely safety concerns and should be addressed.

At times, when going over bumps, the brake pedal feels hard and hard to push to the floor. Other times, the brake pedal shakes and the vehicle feels as if it is shaking. The vehicle does not stop when brake pressure is applied. At other times the brakes lock up and I skid across pavement. There are never ABS lights on the dash though. I have replicated this issue with a technician in the vehicle. The dealership has documented that they have been able to recreate this issue multiple times. The dealership even replicated the issue in a demo model the sales manager drives. This vehicle is unsafe. I have slid out into oncoming traffic multiple times now. I almost ran into my own home because the brakes would not work. At times, my brakes lock up going over uneven surfaces. The issue occurs frequently in parking lots, where I am afraid to hit a pedestrian. The vehicle drive, other drivers, passengers, and pedestrians are put at risk by this safety issue.

The ABS braking problem has not been mentioned to Hyundai or any other company or organization to date as it was just recently experienced. I recently put unscreened millings on the road end of my gravel driveway. When coming to a slow stop before entering the public road I now experience the brake vibration or chattering with deminished braking responce. Fortunately, I have not experienced this while driving on a public road in 35,000 miles.

- Lehighton, PA, USA

Leaving parking lot. Approaching Exit to street to turn right. Going slow and applying the brakes. Hit a small crack or pothole in the pavement and the ABS kicks in. Brake shutters when abs occurs, but braking pressure is very light and car almost rolls into intersection. I think I had to quickly release brake and step on brake again to be able to stop the vehicle. It happened very quickly Vehicle is 1 year old. No lamps or codes. Happened again in similar situation. Trying to stop at lower speed. Hit a bump or loose gravel. Abs kicks in and braking pressure is drastically reduce even after getting past the crack or gravel

I steep on the brakes when I was coming to a gas pump when I did that the car started to shake. It's seams it's was the ABS I thought the car was not going to stop. I had to press the brakes all the way down for the car it stop. I thought for sure I was going to hit the car in front of me.

- Allentown, PA, USA

The ABS seems to kick in over aggressively. It will kick in and the brake pedal gets all jiggly on slight changes in road situations. For example, going into my driveway, driving over a manhole cover, etc. This has felt dangerous in several instances if I'm slowing down for a red light and the ABS kicks in and significantly increases my stopping distance.

- North Bend, WA, USA

When slowing down from a slow speed the car will begin to shake. This is intermittent.
