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.

- Aurora, CO, USA

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.

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.

- Spring , TX, USA

When hitting a pothole or bump at low speeds the braking system fails and does not brake. As if the abs system engages and leaves me going further when i need to stop. This problem always happens on the same street where i live

My wife nearly crashed into a vehicle because the brakes on her 2023 Palisade would not work! I researched and she is not the only one this has happened to. It seems to be a known issue but there is no recall assigned to this, which is a huge safety concern for my wife and for our daughters, which were in the car when this happened. It could have been much worse if the brakes failed and the car were to drift into cross-traffic! This needs to be addressed immediately before someone gets seriously injured or even dies! In the meantime, our Palisade will not be driven.

- Dallas, TX, USA

The car would not brake when approaching a stoplight and I nearly ran into the vehicle in front of me. I had my daughters and a friend of theirs in the car and it could have been disastrous if I were to have not been able to brake and drove into cross traffic! This issue needs to be addressed immediately before someone gets seriously injured or dies!

Over sensitive ABS when going over bums or bumpy roads the breaks get really hard, makes a loud cranking noise and break peddle starts shaking really bad unable to bring the car to a complete stop I-??ve taken it in and they said they couldn't mimic that reaction. It feels very unsafe specially when you have little kids in they car.

*Conditions: sunny, dry, about 70 degrees While driving at a lower speed (< 20 MPH), I started applying my brakes just before going over a railroad track. After starting to initially slow down, I crossed the railroad tracks and my brakes started pulsing very loudly but were no longer slowing down the car. Despite breaking about 5 to 6 seconds before the car in front of me, I just keep on rolling right up to the point where I was going to hit them and then the auto-safety stop slammed my car to a halt. I may have actually hit them, it was hard to tell. The driver even pulled over, got out and looked at their car, but gave me a thumbs up as if I didn't hit them. I'm extremely concerned that my brakes didn't work in perfect conditions when starting to break with PLENTY of time. I just went online to see if this has happened to others because it was so crazy, and it looks like there are numerous stories just like mine (i.e., when breaking on a bumpy surface). How in the world has this not been recalled?!!! My car has less than 20k miles on it and it has been regularly serviced via Hyundai dealerships. I have dashcam video to verify/corroborate my story. You can see that I was going slow to begin with, started breaking well before I needed to, you can hear my breaks grinding loudly, and the car is just not stopping until the last second before I'm about to crash where it slams to a halt from the automated stopping system.

ABS system activates when braking is applied over rough dry roadways, such as railroad tracks, rubble strips, or general bumps in the road, (minor potholes or manhole covers.)
