2025 Hyundai Palisade

The ABS engaged unnecessarily when I pressed the brake pedal, causing the vehicle to slide forward about 6-10 feet while I was driving at approximately 10 miles per hour. The same situation has occurred three times over the past seven months. When the ABS engages, it takes longer for the vehicle to slow down or stop. This poses a potential risk for everyday driving.

I am submitting this supplemental complaint regarding a repeated and dangerous brake failure in my 2025 Hyundai Palisade. This is a follow-up to my original complaint submitted in July 2025. On multiple occasions while driving at low speeds (around 5 mph), including turning into driveways or approaching intersections, the braking system failed to respond properly. The brake pedal felt like it lost connection — similar to how a bike slips when its brake fails. The vehicle kept moving forward even while I was applying the brake. This nearly caused accidents several times. I believe the automatic emergency braking system (AEB) also failed to engage. One incident caused me to hit a fence, resulting in a small dent. Hyundai is now refusing to repair the safety systems under warranty because of that dent — even though the dent was a result of the brake malfunction. I brought the vehicle to an authorized Hyundai service center, and they refused to cover the issue under warranty or provide a loaner vehicle, leaving me to drive a potentially dangerous car. I also want to note that I have seen multiple recent NHTSA complaints from other Hyundai Palisade owners describing similar brake issues. This suggests a wider pattern of brake failure, which must be urgently investigated before someone is seriously injured or worse. Hyundai has failed to properly investigate the issue or assist me in any meaningful way. This vehicle is still under warranty, and I am unable to safely use it while they delay responsibility.

Brake system failure. Driving on uneven surfaces (train tracks, pot holes, payment dips, rock, etc.) causes the brake system to fail to stop the vehicle. Causing a minimum of a 5-6 ft. stop. The car continues forward and the brakes fail to stop. The brakes feel like they are slipping during the slightest compression. The vehicle does not stop at all. The brakes grinding and hop to a stop eventually but only after several meters. There is automatic loss of brakes with the slightest uneven surfaces. No warning lights come on. Nothing is activated on the control system. No indicators show during the malfunction. Just terror and fear when attempting to break on anything but a brand new paved road. Car is currently in the manufacture dealership for inspection. Safety for my family and for other drivers cannot be maintained when I am unable to stop the vehicle if there is the slightest imperfection in the road.

While driving on the highway using the adaptive cruise control feature in my 2025 Hyundai Palisade, the vehicle suddenly and aggressively braked for no reason — even though there was no vehicle or obstruction ahead. This happened in normal highway traffic and caused vehicles behind me to brake suddenly, putting me at extreme risk of a rear-end collision. It was a very dangerous and terrifying experience that made me unable to use the cruise control feature since. For a brand-new vehicle with advanced safety features, this type of malfunction is completely unacceptable. Hyundai has not provided a proper explanation or resolution. This poses a serious ongoing safety risk to myself and others on the road and must be investigated.

While turning into a driveway at low speed (approximately 5 mph), I attempted to brake, but the brakes did not respond properly. The vehicle began to bump and resist braking, and failed to stop when expected, causing me to hit a fence. This model is equipped with automatic braking and collision avoidance systems that should have activated, but they failed to engage. This was a concerning failure for a brand-new vehicle equipped with advanced safety systems. Hyundai has not provided any clear answers or support. This appears to be a malfunction in the braking or electronic safety systems, and I believe it poses a serious risk to other drivers and pedestrians

[XXX] - The brakes on Hyundai Palisade make grinding sound when backing out of my driveway. [XXX] - The brakes on Hyundai Palisade make grinding sound when as I was turning into the bay at car wash. [XXX] - As I was approaching stop sign brakes made grinding sound, vehicle was not slowing down and I had to pump the brakes 3 times. The brake pedal went all the way to the floor. If another car would have been in front of me, I could have hit them from behind. [XXX] - The brakes on Hyundai Palisade make grinding sound as I approach stop sign. Dry Blacktop surface.

driving down gravel and uneven road when trying to break at stop sign. Car would not slow down or break as another car was coming down the road. At this time is when I pushed the break petal all the way down car was still not slowing down, the car started to do the death wobble, shake violently and vibrating, pulsing back and forth side to side up and down, steering wheel shaking. I had to let off the break and press the gas to hurry and speed up before the oncoming car hit me with my 2 small children inside. I have taken my car to the dealer ship and they told me there is no recalls for the 2025 Hyundai palisade my car has 5,036 miles on it bought it brand new off the lot, the service representative states they will look into it that it may take 24-48 hours to get back to me, but this may also be a suspension component but they will look into the incident. There were warnings signs and I take this route everyday every time I would break I could never fully press the break down as it would start shaking and make metal on metal noise and I would have to ease off the break petal.
