2024 Hyundai Palisade SERVICE BRAKES,FORWARD COLLISION AVOIDANCE

There have been many times when driving, specifically over bumpy ground, but it has also happened over smooth/dry ground, where it feels like the anti-lock brakes suddenly kick in when they are not supposed to causing an inability to brake. You have to take your foot off the brake and brake again. This has caused several close calls of rear-ending someone or running through a stop sign or light. You must be keenly aware that this sudden braking inability/shaking of car, etc may happen and there always needs to be a lot of room in front of you. I mentioned it to the dealer, they noted there was nothing they can do but that they have reported it to Hyundai and Hyundai is aware and they have had other complaints. It has not been reproduced or inspected by anyone else at this time. I have not had any warning lamps or messages.

There is a known issue documented online regarding the 2024 Hyundai Palisade and the ABS system. On multiple occasions we have noticed that when driving at slow speeds (less than 25 miles per hour) and if the road is slightly uneven, gravel, on an incline or decline, the brake pedal start to vibrate and there is loss of control and increased stopping distance. We reported this previously to Hyundai dealership and they found no fault. Today, 9/30/25, the care was involved in a low speed collision in which the Palisade rear ended another vehicle. Once again the car started to skid and hit the other vehicle. I dropped the car off today at the dealership.

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.

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.

While driving and slowing down at a stop light the car started to trigger the anti lock brakes. The car was shaking and it would not stop. I put the car in park right before hitting the car in front of me. It was a sunny day with no poor road conditions. The road was a little bumpy but not anything extreme.

I was coming down a hill slowing down and when I hit a dip in the pavement the abs engaged and the car was shuttering and would not stop. It has happened a few times now on uneven surfaces like potholes or bumps in the road.

Date: [XXX] Time: 12:00 PM Location: [XXX] (heading toward [XXX] ). - Turned left into the second entrance to the parking lot between [XXX] and [XXX]. My Vehicle: 2024 Hyundai Palisade Night Edition Incident Summary While entering the parking lot, the vehicle in front of me braked. When I attempted to brake (approx. 10 mph), my vehicle: - Began pulsing/jerking, consistent with ABS engaging. No matter how hard I pressed the brake my car would not stop it's kept pulsing - alerts and Beeping with a forward collision warning went off - car Lurched/jumped forward rather than stopping smoothly. This resulted in a minor rear-end contact with the vehicle ahead. Concerns for safety of myself and others because the car did not stop when hitting the brakes nor the collision warning initiate braking. CONCERNS - Concern that ABS or forward-collision system malfunctioned. - Service appointment scheduled for 9/9/2025 at 9:45 AM with Hyundai dealership. - Will keep a copy of the service summary for documentation.

[XXX]. While approaching a red light traffic signal ABS kicked in with a slight acceleration and reduced braking. There was a car ahead of me stopped at the red light. Applying normal pressure to the brakes was not slowing my vehicle requiring me to use both feet to force enough pressure to the brakes to stop within feet of hitting the vehicle in front of me. This was on a main public road and the road was rough. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have taken my car into Hyundai three times time. When I am driving, coming up to a stop at a light, sign or because of a hazard, there are times my brakes lock up completely and I cannot stop my car. Each time I've taken my car, I've been told "we cannot replicate the problem we are unable to fix it" It happens at least 5-10 times a week. I've almost crashed at least 7 times and I have to move over to try and move out of the way, slam down my brakes in hopes that something clicks and I can stop. I know that I will crash one day but my equity is negative on my car and there isn't anything I can do. I have young children in my car and I could be a risk to anyone else on the road and I'm extremely disappointed in how Hyundai is handling this.

While approaching a stop sign we hit a small crack in the roadway while applying the brakes. The brake pedal started pulsing and the vehicle would not stop. Luckily there were no cars approaching because we rolled thru the stop sign. This is the second time in a month this has happened. Apparently the manufacturer is aware of the issue but have not seen any type of recall.

Sometimes when trying to break on uneven surfaces the break seems to fail, shaking the car as if trying to break multiple times, which results in the car continue moving sometimes 10 feet over the stop sign, for example. The uneven does not need to be gravel, just minor bumps on the road sometimes trigger this issue, which makes me scared that I'll end up in an accident, as I already had a near miss one. This has happened now multiple times and is making me scared to drive. I took the car to Huyndai on 08/15 and they were able to reproduce the same issue, saying that it seems to be a misreading from the ABS system, but added that the car and its systems are functioning as per the designed specifications and there was nothing they could do. Their solution was to advise me to use more caution when breaking, avoiding sudden breaks and to allow for increased breaking distances, but this absolutely does not resolve the issue and places the responsibility to resolve the issue on the customer, which is absurd. I should add that the many times this issue happened to me, I was driving at very slow speeds (max was like 20 mph) and was slowly stopping at the stops signs of my gym center and the parking lot of my work, which leads to a busy highway. I am afraid one day I won't be able to stop the car and end up going into the highway and cause an accident hurting both myself and other people. This is incredibly irresponsible of Hyundai, it's playing with people's safety. I would have not bought this car had I known this was an issue.

*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 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)

Car skidding when I hit the break on uneven surfaces, specifically going down an incline. My car almost skid into oncoming traffic.

When I am stopped at a traffic light (or even when traffic comes to a stop on the interstate highway in traffic), when I begin to drive again, all of a sudden the automatic braking system engages and slams on the brakes when there is nothing in front of me that I could collide with (because the car in front of me has driven forward and out of the way). Each time it happens I am terrified the person behind me is going to rear end me because I have started to drive already and the car suddenly and inexplicably slams the brakes on hard. I can’t find a rhyme or reason to when this occurs - I can go weeks without it happening and then suddenly it will happen once or twice and then weeks again without it happening - making it tough to recreate.

ABS locking up when slowing down.

The ABS system is over sensitive or not working properly. If I am applying minimal break pressure over any uneven surface such as a small crack in the road, bump, gravel or uneven surface the ABS will engage and cause the vehicle to lurch forward at least 5 feet. This has caused multiple near miss accidents. This is an accident waiting to happen.

i have had multiple incidences over the past year where in stopped traffic, the car will suddenly slam on brakes as all cars start to pull off in traffic. I have almost been rear-ended by the car behind me with these sudden stops. Often when this happens I try again to pull forward and it will slam on breaks again and I have to quickly put it in park and then drive again to get it to let me begin to drive forward. There is nothing blocking my path forward. This usually in multi-lane traffic stops, so it appears that it is confused by the movement of cars in front of me and beside me. I did take it to the dealership and they could not replicate the issue since it is intermittent. They did not see any error codes that were logged either so couldn't help me with the issue. I also receive for long periods of time when driving more than one hour a message on the instrument panel that says "Forward Safety system limited. Radar blocked." This eliminates cruise control and forward safety systems linked to radar.

The car exhibited an inability to effectively brake in a very common situation (braking when traveling at low speeds on slightly bumpy ground). I was approaching the end of our driveway and started to apply the brakes as I passed over some slightly bumpy ground asphalt. The car lurched forward repeatedly as the brakes were applied, bouncing forward in spurts rather than stopping and taking twice as long to stop than it should have; I was a couple of feet from entering the roadway despite beginning to break with plenty of time to stop.

Automatic emergency braking. Vehicle has had several instances of slaming on brakes for no reason. Last time we were traveling about 35 miles per hour with a vehicle traveling behind us when system slammed on brakes locking them up and bringing us to a complete stop. We were traveling in the dark, in a rough road in a construction zone. No warnings lamps or messages. Scared us very bad. We are having the vehicle checked the next time we have in for service. Seat belts not fixed as of last service 10/25/25, per dealer no remedy available at this time.

Coming to a stop sign, brakes would not engage, steering wheel shaking loudly. 1mm from rear ending the car stopped in front of me. The emergency brake came on right before I would have crashed. Prior to the brakes not engaging/wheel shaking no lights or warning signals from the car.

When braking on an uneven surface, the anti-lock braking system will sometimes kick in, causing the car to shake and not deliver the stopping power the driver expects. I've nearly rear ended multiple people and have glided out into intersections before. Typically happens when leaving parking lots, coming to 4 way stops, or pulling into driveways. I've also had the emergency braking system kick in on a few occasions while this happened. You lose all ability to maneuver the vehicle when this happens. I've had the dealership look at this multiple times only to tell me that it's my driving habits causing the ABS to initiate. A simple search online shows that lots of 2024 Palisade owners are reporting similar issues. I do not believe Hyundai understands how to fix this issue yet.

Many times while my car was set to the adaptive cruise control the car wouldn't stop or break at all although the car in front of me braked and stopped completely. I had to slam on the break because the car wouldn't stop on its own.

This has happened to me on 6 different occasions. While driving at slow speeds, and applying the brakes, the vehicles ABS system kicks in for no reason. However, while doing this, the vehicle is not slowing down and feels as though it will not stop. The only thing that stops the vehicle is the emergency brake that kicks in when the sensor feels I am getting too close to the car in front of me. I have been close to hitting the front car on several of these instances and another time, I stopped because I turned the wheel to the curb and the sensor picked up the curb and suddenly stopped the car. I have noticed that this happens more if the road is not smooth. The vehicle was taken back to the dealer for service and no change was done because they could not duplicate the problem.

When applying the brakes as you approach a stop light or vehicle etc.. the vehicle will apply or go into an ABS event and lock you out of the brake pedal so you can't apply any more pressure to the pedal and will not stop the vehicle without a collision. I have had this happen several times and have had to steer into the ditch or oncoming lane to avoid an accident. This has occurred at slow speeds as well as highway speeds. This is a very dangerous situation and will cause an accident
