2024 Hyundai Palisade

Over the last week my Palisade has kicked on the ABS brake feature which has resulted in the vehicle to not stop timely. This was on a flat, paved road and was no reason for this feature to kick on. It has nearly resulted in an accident. We have brought to dealer and reported the issue but seems to be a more wide spread issue than we thought after doing some research online.

I am reporting a recurring and hazardous issue with my 2024 Hyundai Palisade. When driving over uneven or bumpy surfaces—such as city streets with potholes, manhole covers, or brick pavement—the braking system fails to respond appropriately. Despite applying the brakes at low speeds (approximately 25 mph or less), the vehicle does not decelerate as expected. This results in extended stopping distances of approximately 15–20 feet, posing a significant risk of collisions or harm to pedestrians. This issue has occurred multiple times under various conditions, including dry roads and moderate temperatures. There are no warning lights or error messages displayed on the dashboard during these incidents.

My brakes are intermittently disengaging during bumps and potholes. I experience a rattling undercarriage and pedal vibration. Sometimes I must crank the steering wheel to regain braking. This poses an immediate safety risk to myself and others. The service advisor mentioned other customers coming in for the same issue. I have had my car in three times for this issue but they’ve never been able to replicate the issue. It has been an ongoing issue since the inception of the lease but has gotten progressively worse. This is a life-threatening issue.

Vehicle Safety Concern - Unintended Vehicle Movement Vehicle Information: 2024 Hyundai Palisade Incident Date: XXXXXXX Location: Commissary parking lot in [XXX] Incident Description: On XXXXXXX my wife parked our Hyundai Palisade in a designated parking space at the commissary. She properly engaged the parking gear selection and turned off the engine. After opening the rear hatch to retrieve shopping bags and securely closing it, she proceeded into the commissary to shop. Upon returning approximately 15 minutes later, she discovered the vehicle was no longer in its original parking position. The Palisade had rolled away from where it was parked and collided with a parked 2018 Toyota Sienna, resulting in property damage to both vehicles. Actions Taken: Due to concerns about a potential mechanical defect that may have caused this unintended vehicle movement, we immediately contacted Hyundai customer service. We have since scheduled and completed diagnostic inspections at two separate Hyundai dealerships. Both dealerships performed comprehensive diagnostics but reported finding no mechanical issues. Safety Concerns: This incident represents a significant safety hazard. The unintended movement of our vehicle in a parking lot could have resulted in serious injury to pedestrians or other motorists. We are deeply concerned about the potential for this incident to recur and cause harm to others. Request for Investigation: We respectfully request that NHTSA investigate this matter to determine if there is a systemic safety defect in the Hyundai Palisade that could cause unintended vehicle movement when properly parked. We believe this incident warrants investigation to protect public safety. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When braking on uneven surface like gravel, bumps, ect. The vehicle may shutter and continue lurching forward. Takes around double the stopping distance expected and has been close to accidents multiple times. This has happened many times since purchasing the vehicle brand new in 7/2024. No warning lights or messages pop up when this is happening. We took the vehicle in for inspection around 2/2025 but they could not replicate the issue so didn't even look at the parts for any concern. No other person has examined the vehicle besides the dealer on that visit. Vehicle is available for inspection upon request. Is definitely a danger to drive in good road conditions but very concerning to drive in rain or snow with not knowing if the brakes will perform or not.

I will drive at low speeds (on residential or approaching stop light) and start pressing my brakes and then the car starts violently shaking and DOES NOT STOP… it keeps rolling forward. I lose brake power. The longest distance I’ve went without brakes working was 20 feet. I have little children and bought this car for safety features. I feel extremely unsafe. The problem is intermittent and Hyundai doesn’t know how to fix the issue because they stated there is no “check engine lights or codes” popping up. Very dangerous. This is going to get people killed. They need to recall Hyundai palisades for brake issues.

Hi, my name is [XXX] and I leased a 2024 Hyundai Palisade Calligraphy last summer. I have been having issues with my car skidding on rough or uneven pavement and I brought the car in for service to check the issue. I was told by the dealership that my issue is "normal" and it's how the ABS system works. This is obviously ridiculous because no car is supposed to skid on regular roads with no snow or ice. The car skids and the wheel shakes and my brakes do not work for a few seconds. I have to basically slam on the brakes and pray the car stops. I told the dealership it is definitely not normal. They said they would check the car and call me. I got a call a couple hours later telling me the ABS system is working fine. When I googled the issue, I saw many, many complaints about this issue and a class action lawsuit that has been filed. I picked up my car and asked the representative to speak to a manager. He said they all leave at 4:00. It was 4:30. I asked him how Hyundai is ok with sending people like me back out on the road knowing the ABS system is faulty and causes loss of brakes? He replied "Until Hyundai issues a recall, there is nothing we can do." I have owned Hyundai cars in the past and have always admired them as a company. They offer great safety and great warranties. But now I ask why they are ignoring this obvious safety issue? What will happen when a person driving a Palisade loses brakes and God forbid hits a car or a person? Please make this right and fix these cars so that we can feel safe on the road. My children drive my car, though I won't be allowing that anymore.Please advise on next steps.
