2024 Hyundai Palisade

When going over an uneven surface (railroad track/cobblestone/pothole) at a low speed, specifically while braking, the car starts violently shaking and prevents me from stopping the car. It has caused my car to go an extra 15-20 ft and even had to narrowly miss being T-boned twice (thank goodness the people coming saw me!) From what I’ve seen it is the ABS that is sensitive, but I’m not certain. I just know that it is dangerous and concerns me with children in the car. Dealer could not reproduce and told me it was “normal” over uneven surfaces- even asked why I was braking over the tracks (there is usually a stoplight or stop sign right after!). Hope this gets figured out quickly before someone gets seriously injured or killed, as I see many others have experienced the same. Truly a scary experience every time it happens.

*ABS, yes available for inspection, you can completely examine my car *ABS kicked in without need, hard braking would not work, car pulsed into intersection *No *No *No Thousands are experiencing this involuntary ABS implementation and Hyundai is aware. Today my 2024 and a new 2025 were in the Dealership with the very same problem. My first instance occurred in July 2024

On a number of occasions, the vehicle does not stop when hitting the brakes. The car shudders and shakes violently, while continuing to lunge forward before finally stopping. This has happened to me approaching crosswalks, intersections, and stop signs. This is a problem for many reasons as it is a safety hazard for me and my family, as well as other drivers and pedestrians. I brought my car to the dealership on July 11th, and they told me they had heard of this problem before. They would not return my vehicle because it was a safety issue that Hyundai Corporate is still investigating. On 8/6, my vehicle was returned to me. The dealership said they were not able to replicate the problem (after driving it for 3 miles). They did not fix my car or change anything, but corporate told them to release all vehicles with this issue. This is a safety concern that Hyundai is not addressing.

I have noticed repeatedly when the 3 following conditions are met the anti lock brakes do not function correctly. The vehicle is moving slower. Below 30mph but usually this is below 15 mph. The vehicle goes over a bump or series of bumps I am braking. Usually bringing the vehicle to a stop. The ABS will "overreact" and kick in causing the vehicle to not stop in a timely manner. The ABS will continuously operate until the vehicle stops. Removing your foot from the brakes and reapplying them will fix the problem. Which is counterintuitive as to how ABS works and the problem it alleviates. I would expect a normal vehicle to not even apply the ABS in such a situation as other than some normal bumps or cracks in the road all other conditions are normal. I am not slamming the brakes. I am not employing any emergency steering input. This is just me coming to a slow stop. Note this is an ongoing issue and was not a one time event.

Over the course of 6 mos. I've experienced several instances while braking on uneven surfaces, wherein the ABS system of my 2024 Hyundai Palisade reacted surprisingly very unpredictably. On 2 occasions this caused a near-miss; one of which involved braking while turning a corner on a rough surface and the car skidded/skipped (wheel-hopped) unpredictably. In another near-miss, I quickly released/reapplied the brakes which seemed to deactivate this erratic ABS behavior. My vehicle was recently shopped at my local is Hyundai dealership for routine maintenance/defects. This ABS malfunction was also to be addressed. The dealership reported to me that they were unable to duplicate, the car was operating as intended, no trouble found...Of course, I was highly. unsatisfied with this response, particularly after having taken a test drive with the service department supervisor, demonstrating the issue while driving and reviewing relevant online forum discussions that documented the exact issue I've been experiencing. PLEASE HELP BY DEMANDING HYUNDAI IS IMMEDIATELY ADDRESS THIS LIFE THREATENING ABS SAFETY DEFECT BY MEANS OF AN URGENT RECALL! Thank you.

1. What component or system failed or malfunctioned, and is it available for inspection upon request? Multiple safety-critical systems have failed repeatedly, including: •Engine (multiple shutdowns while vehicle was in motion) •Automated Emergency Braking (AEB) (activating without cause while reversing) •Brake Pedal (intermittently unresponsive with audible rattling) •HVAC (leaking fluid into the passenger-side floorboard) Yes, the vehicle is currently with the dealership (Stamford Hyundai, CT) and is available for inspection. 2. How was your safety or the safety of others put at risk? • The engine has shut off without warning while the vehicle was in motion, including in traffic, creating the potential for rear-end collisions. • The emergency brake has slammed on while reversing, without any obstacles present, risking whiplash and collisions with pedestrians or nearby objects. • The brake pedal becomes unresponsive, with a loose/rattling sensation, making it difficult to slow or stop the vehicle safely. • The HVAC leak creates slippery floor conditions, posing a secondary risk for occupants during ingress/egress. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? The dealership (Stamford Hyundai) acknowledged some issues but stated they were unable to replicate all of them. However, the brake pedal defect is consistently reproducible and occurs daily. Multiple videos and logs have been submitted to Hyundai’s consumer affairs team. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle is currently under inspection by Stamford Hyundai. Hyundai Consumer Affairs (case managers Noorpreet and Taruni) have been involved and have reviewed videos and documentation. No inspections by police or insurance. 5. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No.

On multiple occasions, my 2024 Hyundai Palisade (VIN [XXX] ) has experienced a serious safety issue involving the anti-lock braking system (ABS). While traveling at low speeds (approximately 5–15 mph) over bumps or uneven surfaces, the ABS has unexpectedly activated, preventing the vehicle from slowing or stopping when the brakes are pressed. In each case, the vehicle continued to move for an additional 10–16 feet before the brakes finally engaged. This issue has occurred repeatedly, including on: [XXX] [XXX] [XXX] Each incident created an extremely dangerous situation. I narrowly avoided a collision by swerving to avoid hitting the vehicle in front of me. Fortunately, no pedestrians or oncoming vehicles were in the immediate area—otherwise, the outcome could have been catastrophic. I reported the issue to Koeppel Hyundai in Long Island City, NY, on July 14, 2025, and brought the vehicle in for inspection that day. A technician acknowledged that other Palisade owners had reported similar incidents. Their only recommendation was to disable the "Auto Hold" feature, suggesting it might be contributing to the problem. I followed this guidance, but the issue reoccurred on [XXX] despite Auto Hold being turned off. This is a critical safety concern that requires immediate attention and a definitive repair—not just a workaround. Until Hyundai identifies and resolves the underlying issue, this defect puts drivers, passengers, and pedestrians at significant risk. Please advise on the next steps for a full investigation and proper resolution. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
