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.

When using lane assist the vehicle is pulled into other lanes, including into oncoming traffic. This happens even when the vehicle is centered in the lane. This is extremely dangerous because it can cause an accident. When using cruise control, the lane assist comes on automatically which is extremely dangerous because the vehicle is going at high speeds on the highway. The dealership is aware of the situation. Both the mechanic and the salesman have driven the vehicle with me and experienced the problem. Additionally, the salesman and I drove another 2025 palisade and the lane assist problem was present in that vehicle also.

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.

The contact owns a 2025 Hyundai Palisade. The contact stated while driving two times at an undisclosed speed on an uneven road surface, the brake pedal was depressed, but the brake pedal shuddered and seized. There was no warning light illuminated. The vehicle was taken to the local dealer to be diagnosed, but the cause of the failure could not be determined. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 6,000.

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.

I leased a brand-new 2025 Hyundai Palisade (Calligraphy trim) on June 27, 2025. Immediately after delivery, I noticed the rear air conditioning system was blowing only hot air, making the third-row seats unusable during summer. Despite calling the dealership and Hyundai Corporate right away, I was unable to receive a timely resolution. I had to take the vehicle in for service, which took several days due to part delays and multiple failed repair attempts. During that time, I was denied a loaner vehicle and had to rent a replacement at my own expense. The issue disrupted my plans, cost me money, and caused significant stress. I believe this is a quality control issue in the climate system, and Hyundai’s inability to promptly fix it made it an unsafe situation for families relying on the vehicle for travel.

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
