2024 Hyundai Palisade

Brake/traction system inoperable and fails to properly engage during normal driving conditions with variations ranging from: minimally uneven, minimally wet or minimally bumpy surface. When applying the brakes in these circumstances, the vehicle shakes violently while continuing to proceed forward. This has happened when braking at all speeds and as low as under 20mph. My family has narrowly escaped injury and death on multiple seperate occasions from running off of the road, to rear ending another vehicle, to sliding up through busy traffic intersections. We feel unsafe to drive/ride in this vehicle as we feel like we are playing Russian Roulette. This issue was previously communicated to the service dept at local Hyundai dealership but they were not able to find/replicate issue. I have videos now for proof. There have been no warning lights or other messages that would identify any issue with the vehicle.

On December 19th at about 5pm, I was pulling into a gas station driving at about 10-15 MPH when my brakes locked up and the car started shaking. It felt like the anti lock braking system was activated and I did not have full braking control of the vehicle. I was driving slow enough that the vehicle did finally come to a complete stop. The gas station was flat and the road appeared in good condition, but is was dark outside and about 40 degrees F. No warnings were observed on the dash or heads up display. No one was hurt in or outside of the vehicle. We have only had the vehicle for a few months (purchased used from Carvana with only 6k miles) and only 70 hours of drive time where the issue has never been observed or reoccurred. Hyundai has not yet been notified but I will file a report with them and ask for an inspection although I’ve read in Hyuandai forums that they are aware of this issue and have no root cause or solution.

I was coming to stop speed under 15 (mph) the brake pedal and steering wheel starting shaking violently, and (the) brakes seemed to be pulsating up and down. I had to really push down hard and all the way on the brake pedal and when the car finally stopped my car was passed the stop sign and was in cross traffic luckily the car coming saw and swerved around me. My daughter would have suffered injury if that car hadn’t swerved. There were No ABS or malfunctions in the instrument panel and no audible warnings.” This has happened multiple times and Hyundai states this is inherent characteristic of this model which to me means all Palisades are defective.

I was pulling into my driveway [XXX] when I engaged the brake pedal pushing it fully down to stop behind my other vehicle. The antilock brake system seemed to turn on and the car did not stop. The steering wheel started shaking violently and the car went forward another 10-15 feet and I crashed into my other car, all while the brake pedal was completely down. We brought the car in to the dealership, Ettleson Hyundai in Countryside, IL, where they could not reproduce the event. They changed out the main governor of the ABS system anyway.

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.

Vehicle brakes began locking up when braking on bumpy areas. Took in to dealership on October 7, 2024 and left it with them all week. I went back to pick it up and they said it needed a software update and was fixed. A few days later the brakes repeated the locking up on bumpy areas again. After waiting 6 weeks for an available loaner car my vehicle is back the dealership, it’s been nearly a week again and I haven’t heard any news.

My wife and I purchased a new 2024 Hyundai Palisade Calligraphy in May 2024. It has roughly 5500 miles now. For the most part, we have been very pleased with the vehicle. There is one major thing that is wrong but is not yet recognized for the 2024 model. We are experiencing an issue similar to a handful of the 2023 models, which is with the braking system. During braking over uneven or bumpy roads, we experience a violent shaking of the vehicle and steering wheel, as well as loss of braking (or just very very very degraded). It has caused us some close calls with almost rear ending vehicles due to the loss of braking when it is needed. It has only occurred at lower speeds (roughly under 30mph) with varying degrees of brake pressure. The only way to get it to stop is to fully release the brakes, and press the petal again (hoping you still aren’t over any bumpy part of the road). There are no warning lights or indications on the dash showing a failure during this time. My wife is the primary driver of the vehicle, but together we have experienced this over 15 times since owning it. I have taken it to the dealership we purchased it at and unfortunately the roads were too smooth in that part of town to replicate the issue. They ran diagnostics and test drove themselves too but still nothing. We did verify ABS works properly and it does. There is no shaking or degraded braking when the ABS activates. I plan on taking it to another part of town that is bumpier to have a different dealership ride with me so I can show them what it does, but I have not done so yet. From reading around, others have voiced concerns to Hyundai corporate already and have received responses stating that it is normal. I can assure you that this is not normal for a vehicle to do. My guess is that similarly to the 2023 Palisade, it doesn’t affect a lot of vehicles. But with the ones it does, it is just the matter of time before an accident occurs that will harm/kill someone.
