2024 Hyundai Palisade

The contact owns a 2024 Hyundai Palisade. The contact stated that while driving at an undisclosed speed, the steering wheel vibrated and was shaking erratically. In addition, the brake pedal was depressed; however, the brake pedal was difficult to depress. The contact stated that the brake pedal needed to be depressed extremely hard to stop the vehicle. There were no warning lights illuminated. The contact stated that the failure occurred mostly on bumpy roads, regardless of the speed at which the vehicle was being driven. Additionally, the traction control was independently activated. The contact stated that the failure was persistent. The vehicle was taken to the dealer; however, the failure was not duplicated. The vehicle was returned to the contact; however, the contact stated that the vehicle was a death trap. The contact stated that the vehicle was unsafe to drive. The contact stated that the vehicle was unsafe and had to transport her kids back and forth to school in an unsafe vehicle. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 1,000.

I am unsure what exact component malfunctioned but in 5 separate times within the past 2 months, the vehicle has failed to stop at a normal time when pressing the brakes and a loud rumbling occurs. It feels as if I am sliding on ice.Two of the times it occurred on uneven road surfaces, however 3 times I could not identify an issue with the road. They all occured when coming to a stoplight/stop sign or when I had to stop due to a vehicle slowing down or stopping in front of me. In each occurrence I was going under 20 mph. The safety of others could have definitely been impacted as it took a few seconds to actually stop the vehicle more than it should have. Someone could have been walking and crossing the street in front of me. Or if I was too close to the car in front of me it could have hit it. No warning messages appeared on the dashboard prior, but during the occurrence in the last time, I noticed the word "shift" appear. This word could have shown up during the first few times and I could have missed it. On Tuesday September 9th I took it to the dealership and they checked everything out and the vehicle did not produce the same symptoms when they tested it out over the hour I was there. They said they reported the issue but they did not know the reason it was occuring.

On 8/23/25 at approximately 7:20 PM, the vehicle approached a red stoplight in a turn lane to merge onto the highway, the car began to shake violently and the brakes functioned only minimally, not allowing the vehicle to slow down/stop as expected. The vehicle eventually came to full stop, however, given that there was another vehicle in front us that was stopped, there very easily could have been an accident, putting myself, my husband, and 3 year old son, as well as other vehicles, at risk of an accident/serious injury. The car, thereafter, functioned normally. The car was taken into the dealership, however, they stated that they could not duplicate the issue and there was nothing wrong with the braking system. There were no warning lights displayed on the dashboard. Upon further investigation, it appears other Hyundai Palisades have had similar issues, some resulting in serious accidents/injury, however it does not appear that the dealerships or Hyundai have provided any answers or ability to fix this issue.

I was driving my vehicle through a parking lot at a low rate of speed (approximately 5 mph) with my wife and three children in the car. A pedestrian suddenly stepped out from a shopping strip on the passenger side to cross the road, about 8–10 feet in front of my vehicle. I immediately attempted to apply the brakes manually. However, the vehicle’s automatic emergency braking system unexpectedly took over and completely prevented me from braking. At that moment: - The car began vibrating and shaking while continuing forward at the same speed. - The brake pedal was locked and completely unresponsive to my repeated attempts to press it. - The pedestrian, realizing the vehicle was not stopping, was forced to jump out of the way to avoid being struck. After several seconds, the automatic braking system finally disengaged, at which point the brake pedal returned to normal function and I was able to regain manual control. This incident was extremely dangerous and could have resulted in a catastrophic accident, with both my family and the pedestrian at serious risk. The automatic braking system not only failed to stop for a pedestrian directly in front of the vehicle, but it also disabled my ability to manually apply the brakes.

When I am braking on a road with bad condition (bumpy, uneven, some minor potholes, etc.) the car starts to skid causing the wheel to shake, I lose control of the vehicle, and my stopping distance increases. It's like the ABS is overly sensitive and kicks in whenever the road has any of the problems stated above. This has almost led me to rear-end another car who is in front of me several times. This problem happens almost daily. My children, husband, and I drive in this car daily and it puts all of us at risk. I took my car to a Hyundai dealership , (Napelton's Auto Park of Urbana) and they were not able to reproduce the problem, therefore they could not find anything wrong. The vehicle and component have not been inspected by anyone except for the dealership mentioned. No warning lights, messages, and other symptoms have been displayed at any point in time, before, during, or after the problem occurs.

This vehicle has driver-assist functions and warning lamps in the electronic instrument cluster located in the driver's display area. Randomly and unpredictably a group of warning lights -- "check blind spot" collision alarm, lane safety indicator light, triangle-shaped general alert icon -- all activate simultaneously for no apparent reason. The unpredictability creates a serious distraction to the driver and potentially unsafe reactions which could result in damages and injuries. There are numerous references to this problem on the internet, indicating this is a widespread safety issue for Hyundai models. Dealer said possible recall imminent.

ABS system is malfunctioning when going over bumps. For instance, I tried braking when going over small bumps and car started jerking and skidding almost rear ending car and finally brakes kicked in at end. Happened 4 times now after buying it a year ago. This is a known incident online that needs to be addressed. Could be very dangerous at higher speeds and cause a wreck. Dealers apparently aren’t doing anything or Hyundai.

Since early ownership, my Palisade’s ABS activates improperly on bumpy/uneven surfaces like railroad tracks, construction zones, causing brake pedal pulsing, vibrations, and significantly longer stopping distances. Braking feels ineffective, as if the brakes “don’t catch,” unlike my wife’s new SUV, which brakes normally on similar surfaces. This occurs at low to moderate speeds (10-40 mph) on dry, rough roads like potholes or gravel, but not on smooth pavement. I believe the ABS/traction control system misreads wheel speed, reducing braking efficiency and posing a safety risk. The issue occurs 2-3 times weekly crossing railroad tracks near my home and daily on my highway commute through construction zones. I must maintain extra following distance (4-5 car lengths at 40 mph) to compensate, which is challenging in traffic. This defect nearly caused two collisions. In both, braking on rough surfaces at ~30-40 mph (with 2-3 car lengths ahead) extended stopping distances, forcing me to swerve into the breakdown lane to avoid rear-ending vehicles. This endangers my family and contradicts Hyundai’s safety ratings, a key reason for my purchase. I reported this to Branfon Hyundai in East Haven, Connecticut at my 7,000-mile oil change around November 2024 and was verbally told it was fineand again at 14,000 miles and asked them to document it April 2025. Both times, they documented my complaint but claimed it was “normal ABS behavior” and felt typical, offering no repairs or diagnostics. After another recent incident today I research the issue and the [XXX] v. Hyundai lawsuit (filed May 2025, CA) confirm similar ABS issues in 2023-2025 Palisades. Please investigate this ABS defect for a recall to fix braking performance. My family relies on this vehicle’s safety and was the main reason I bought it and most people who have families are sold at this safety award. I can provide service records or videos if needed.

I am writing to formally report a safety concern regarding the Anti-lock Braking System (ABS) in the 2024 Hyundai Palisade, which I believe may be a widespread issue affecting this model year. The problem has raised significant safety concerns, as it directly impacts the vehicle's braking performance. Recently, I began experiencing issues with the ABS system in my 2024 Hyundai Palisade. The brake pedal feels unusually soft or pulsates when braking, and there have been instances of skidding or loss of traction during routine stops were I have ended up in the middle of an intersection. I took the vehicle to a Hyundai service center, where they claim the system was performing normal. The technicians noted that the issue could be linked to the ABS control module or wheel speed sensors, but they could not provide a definitive diagnosis. The system has not been able to function properly since the issue started, and I am concerned about the vehicle’s safety. As a safety-critical system, the ABS is essential for maintaining control of the vehicle during braking situations, particularly under adverse driving conditions. The malfunctioning ABS system poses a significant risk to the safety of both the driver and passengers, as well as other road users. The inability to rely on the ABS system increases the risk of accidents, particularly in situations where braking efficiency is crucial. I have contacted my local Hyundai dealership for assistance, and they have attempted to address the issue through diagnostics and repairs. However, the problem persists, and I am concerned that this may not be an isolated case but rather a widespread defect affecting other 2024 Palisade owners. Given the severity of this issue and its potential to affect a large number of consumers, I respectfully request that the NHTSA investigate this problem to determine if it is a manufacturer defect that warrants a recall.
