2024 Hyundai Palisade

when going over roughts that are considered rough the abs braking system does not engage and I have multiple times of almost hitting the vehicle in front of me cause the abs are multiapplying but not stopping in a normal time, instead the distance is longer...this only happens on rough roads currently and not off roading but actual concrete/asphalt service/highway roads

I've been dealing with an ongoing issue with my ABS kicking in when slowing down and driving over a bumpy surface since I purchased my car. I first reported this issue to Hyundai dealership and Hyundai Corporate Customer Care in July 2024.(As well as the NHTSA) At that time I had experienced this issue around 5 times. Since then, up to the present, I experience this issue on a regular basis and have brought my car into the local Hyundai dealership 4 times over the past year to fix. Each time I got the car back...it still was not fixed. I even had a technician from the dealership ride with me so I could show them...and he verified there is a safety issue. The dealership communicated with the Hyundai tech line and they were instructed to replace the ESC module in the ABS system. I picked up my car today, and the issue is still there. I went back to the dealer and even showed them a video of it happening today and the dealership said there is nothing they can do. Hyundai claims there is nothing wrong even though I have several videos and even had a local mechanic from the Hyundai dealership ride with me to experience this safety issue. I have called Hyundai Corporate again to escalate this safety concern. There is clearly a big problem and Hyundai needs to fix it before there is a serious accident or injury. Maybe pressure from your administration could help. I am willing to speak with anyone needing more information or copies of some of the videos I have taken.

Date: [XXX] Time: 12:00 PM Location: [XXX] (heading toward [XXX] ). - Turned left into the second entrance to the parking lot between [XXX] and [XXX]. My Vehicle: 2024 Hyundai Palisade Night Edition Incident Summary While entering the parking lot, the vehicle in front of me braked. When I attempted to brake (approx. 10 mph), my vehicle: - Began pulsing/jerking, consistent with ABS engaging. No matter how hard I pressed the brake my car would not stop it's kept pulsing - alerts and Beeping with a forward collision warning went off - car Lurched/jumped forward rather than stopping smoothly. This resulted in a minor rear-end contact with the vehicle ahead. Concerns for safety of myself and others because the car did not stop when hitting the brakes nor the collision warning initiate braking. CONCERNS - Concern that ABS or forward-collision system malfunctioned. - Service appointment scheduled for 9/9/2025 at 9:45 AM with Hyundai dealership. - Will keep a copy of the service summary for documentation.

The ABS system in my 2024 Hyundai Palisade Limited engaged abnormally while making a slow turn. I was going about <10mph when my Palisade started to shake violently and I could not brake nor control the vehicle. I had two other passengers and if I was unable to gain control I would have jumped a curb and possibly rolled over since I was in a turn. I have not reported this nor spoken to a dealership. I am not sure how this will help since this has been reported multiple times by other Palisade owners and dealerships and Hyundai refuse to do anything about it. There were no warning lights or messages displayed. The vehicle also has the latest software update applied.

When going over roads with small bumps that are spread a few feet apart, pressing the brakes unexpectedly engages the ABS. This causes the braking distance to increase drastically and also requires the brake pedal to be pressed with excessive pressure to even stop. This happens consistently and has nearly caused us to rear end the vehicle in front of us.

The palisade seems to have issues when breaking over potholes or bumpy streets. I think you could say they lock up and do not stop as they should. In addition the car actually shutters. This happens more than once in a daily basis because of the area I live in. I’ve brought it back to the dealer twice and because they drive on smooth roads, they do not duplicate this issue, which means they’re likely avoiding the issue because I can tell them where it happens all around my town. It’s extremely unsafe.

[XXX]. While approaching a red light traffic signal ABS kicked in with a slight acceleration and reduced braking. There was a car ahead of me stopped at the red light. Applying normal pressure to the brakes was not slowing my vehicle requiring me to use both feet to force enough pressure to the brakes to stop within feet of hitting the vehicle in front of me. This was on a main public road and the road was rough. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

At low rate of speeds coming to a stop the ABS braking system will activate on uneven surfaces, loose gravel or rough terrain. When this happens you have no control when the car will stop. We've almost went into the back of another vehicle or went out into an intersection. This has happened multiple times and we've been made aware there is a class action lawsuit about this issue
