2024 Hyundai Palisade

There’s an issue with the anti-lock braking system when you drive over a bumpy surface like large gravel that causes the anti-lock system to kick in and apply pulsed braking resulting in the car having dangerously long stopping distances. I’ve had this occur twice. The first time was going downhill on a driveway with large gravel. I tried to apply the brakes to sow down, the anti-lock braking kicked in and just kept repeatedly cycling. If I would have needed to come to a stop, it wouldn’t have happened. The second time it occurred could have resulted in an accident. I was leaving a paved parking lot, preparing to pull out onto a busy highway. When I was preparing to stop at a traffic signal at the end of the parking lot, the lot was bumpy and the ABS kicked in. It kept pulsing and the car didn’t stop until I was past the terrific signal and I was partially into the road before it came to a stop. The ABS system needs recalled.

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 it

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.

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).

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!!!
