2024 Hyundai Palisade

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.

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.

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.

•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.

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.
