Braking on rough road before cross street engaged what felt like anti-lock. Brake pedal vibrated under foot, went all the way to the floor and car failed to stop as expected. Has to release brake completely and reengage to stop. Was quick enough to do do before moving into oncoming traffic.

- Euless, TX, USA

I was in stop and go traffic on a side road. I was traveling about 5-15 mph on an uneven road surface. The traffic stopped in front of me and I applied my brakes. I heard the grinding sound of the anti-lock brakes but my car did not stop. My foot was to the ground on the brake and it didn-??t even slow down. I ended up hitting the car in front of me. This has happened before but I never hit anything before. It happens all of the time on uneven road surfaces such as man hole covered, rail road crossings, or construction or potholes.

When braking on an off ramp, the vehicle began to shudder. The steering wheel and brake pedal were shuddering as well. The vehicle came to slower stop than usual almost causing us to rear end the vehicle in front of us. This has happened prior on uneven roads when slowing/coming to a stop. The dealership does not have an answer and couldn-??t reproduce

When I try to stop on a brick road the abs comes on and the breaks press up on my foot and the car does not stop immediately as it should.

- Kalamazoo, MI, USA

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.

- Austin, TX, USA

I was going about 20mph or less on a bumpy side road in the city and couldn-??t stop at a stop light and almost hit the car in front of me. The brakes just did nothing when I mashed down and finally kicked in and I stopped before crashing into the Honda in front of me. I just reported it to Hyundai and online says there-??s a class action lawsuit for this exact reason.

Our car shuttered quite strongly on two occasions, while going at a low speed (around 5 miles per hour) and applying the brakes over a rough surface (pavers and a speed bump). We advised Larry H Miller Hyundai Peoria Service Department of this when we took the vehicle in for our complimentary maintenance on 12/03/24. They advised there was a TSB with this as a known issue and they found "7949 Front Brake Rotors Warp 51712A00 1.10 verify and found front brake rotors out of round perform front brake rotor machining and test drove car and verify working operation." They also advised their protocol was that the manufacturer would not replace them until the rotors were shaved 2 or 3 times (we have now had them shaved once on 12/03/24).

Breaks occasionally make the car jump or shake excessively. This has happened randomly about 4 times already since we purchased the vehicle.

I was going over a speedbump in a parking lot, following traffic. When my front wheels went over the bump, my Palisade started shaking uncontrollably, I had ZERO brake power and just missed hitting the car in front of me that started to pull away! I reached out to the dealer who stated that this is 'normal' to happen from time to time. This happened in October, 2024. I went to an online forum for a Palisade group on FB and asked and could not believe how many people this has happened to!! The general content was they were all told it was normal too, which we simply do not believe. Then it just happened today!! In my own driveway, gravel. I almost ran straight into the garage door going under 5 MPH, but again, very scary! I carry around my four grandchildren alot and the thought of this happening and them being hurt has caused me to reach out to NHTSA. PLEASE HELP UP GET HYUNDAI TO FIX THIS!!!

I was leaving a parking lot and getting ready to turn onto a busy road with my family. As I approached the road and started to brake, we went over a number of pot holes. When that happened, the whole car started to shake and I noticed that we were not slowing down. I don't know what was going on but I was scared. We were approaching a busy road quickly and I did not feel safe. I pressed HARD down on the brakes and eventually we came to a HARD stop. I told my wife what happened and she said that similar things have happened to her when she was braking and she had to swerve off of the road to avoid hitting the car in front of her. There is definately something going on with the ABS system. Going over the bumps through off the entire system and would't let me brake. I have not taken it to a dealer and it has never been inspected by anyone. Prior to the issue, there were no warning signs that came up prior to the issue, or afterwards.

- Novi, MI, USA

This has occured multiple times. In each event, I was driving over 30mph, and had to brake hard (pushing on the brake pedal to an effort to slow down rapidly). The car's brakes locked up...the abs engaged and braking was good, but it did not release as i let my foot of the brake, causing my car to come to a near complete stop. The car behind me, nearly rear ended me. As noted above, the vehicle's brakes do not release, after a hard brake, when you pull pressue OFF of the brake pedal.

- Richmond, TX, USA

The ABS system is faulty. When traveling at relatively low speeds (<20 mph) and over uneven surfaces (train tracks, pot holes, speed bumps, entering parking lots) the brake pedal will go all the way to the floor while the vehicle stutters. The ABS makes the vehicle shake even after the surface has returned to normal and the vehicle stopping distance dramatically increases from where it should be. This is repeatedly replicated and has nearly resulted in rear-end collisions. Having driven many, many vehicles with ABS systems this experience is NOT normal and needs to be investigated for a recall.

ABS locking up when slowing down.

-??What component or system failed or malfunctioned, and is it available for inspection upon request" My brakes. When I-??m driving slowly over any type on bump in the road, railroad track, pulling in a driveway, dirt roads, or gravel roads my brakes lock up the whole front of my car shakes and the vehicle almost jumps up and down and then it takes about 3-5 seconds for me to be able to slam on my brakes to come to a complete stop while still inching forward before I can fully stop. -??How was your safety or the safety of others put at risk? I-??ve almost ran into a mailbox, almost got rear ended and almost braked out onto a highway because the brakes locked up. My safety and the safety of other is major concern with the brake issue and not being able to stop, those few seconds make a difference. -??Has the problem been reproduced or confirmed by a dealer or independent service center? I-??ve had my car to the dealership 5 times. The second time one guy was able to duplicate the issue, so they fixed some part, but that didn-??t solve my issue I had it back to them within a couple of days. The other times they have not been able to duplicate the issue. -??Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? This last time I brought it an engineer was supposed to come and look at it but when the tech explained what is going on he says it supposed to do that. It is not supposed to what it is doing because it-??s a major safety issue for me and others since I can-??t break. -??Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear" When the issue arises there are no warning lamps or messages that come up on the dashboard or anywhere. Also, no code is thrown when the dealership hooks it up to the machine. Another thing when I-??m driving down the road sometimes you can feel the brakes wanting to lock up for no reason at all. Before I get to any bump

Issues where the breaks are ineffective. Usually at slower speeds going over brick road, uneven surface. Told hyundai about first incident when they did oil change on December 27th (at which time it had occurred twice) and they stated no issues with breaks. Has happened now more often (averaging one time a month or more). Took my vehicle in again on May 20th, 2025, they said they couldn't replicate the issue so I went back to the dealership on May 21st, 2025 and did a ride with a tech where we got the issue to trigger multiple times. Dealership had not provided an update until a few minutes ago. They stated they called their tech service line and that "they could not advise them on a repair" - service manager said that's the first time he's heard that and the car is with his manager and who will be trying to call their local area rep. Said if they cannot advise on a repair, it may not be an approved under warranty repair.

- Louisville, KY, USA

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.

- Plainfield, IL, USA

Car has had multiple issues with brakes where it shudders on brick roads. There have been two incidents on brick roads where the car won-??t brake and has slid into oncoming traffic. Hyundai is aware of the issue but, has no fix for it. They say it is safe however, definitely not safe when sliding into oncoming traffic.

- Winter Park, FL, USA

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.

- Roseville, CA, USA

Over a bumpy street coming to a red light (stop) car stalled and failed to stop almost hitting another car. Car made a funny noise and brake petals needed alot of pressure to pust to floor

- Cleveland, OH, USA

As the vehicle drove over railroad tracks the steering wheel began to shake violently and I attempted to push the brake pedal with my full body weight but the brakes would not work and the car lunged forward, striking the vehicle in front of me. The failure of the brake system on my 2024 Hyundai Palisade prevented me from stopping the vehicle and thus I impacted the vehicle in front of me putting not only my life in jeopardy but also the driver of the car in front of me. I sustained a neck injury and headaches and have required ongoing medical care as a result. This vibrating steering wheel and braking issue has happened in the past several times and was reported to Wiesner Hyundai on several occasions; however, the dealership was not able to recreate the problem. The vehicle has been inspected by the service department at Wiesner Hyundai. There were no warning lamps, messages or other symptoms of the problems prior to the failure.
