Automatic Emergency Braking problems of the 2023 Hyundai Palisade

I was at work and went to move my car in our parking garage. I hit a bump and my front tires started to shake along with my steering wheel, and my brakes wouldn't work. I briefly lost total control over the brakes, steering wheel and tires causing me to almost hit a parked vehicle before everything self corrected. No alerts came on. I recently was hit on my rear passenger side and had repairs done to my vehicle. I had also experienced this shortly after I purchased the car and the dealership supposedly fixed the issue. I’m not shew if the wreck causes this issue to malfunction again or what, but this isn’t safe. I just reported the issue to the collision center that recently repaired my vehicle. Waiting on a response.

System that malfunctioned was the braking system safety was risked because vehicle doesn’t stop as it should at low speed below 30mph. Safety of occupants as well pedestrians and other motorists affected. Problem can be reproduced although dealer refused to confirm. I am in the process of getting it confirmed independently. Vehicle and components not inspected by manufacturer, police nor insurance. Although I am in the process of putting an insurance claim in. The issue has been reported and confirmed by several other owners of same make and model and year. No prior warning of issue to it happening. The problem: at low speed below 30mph and braking simultaneously when going over rough ground (non slippery), potholes or in my accident going over a 6” drain to my garage, the abs kicks in when it shouldn’t and the brake pedal vibrates and the vehicle lurches a bit. The result is that the braking distance increases significantly. I can reproduce the issue in particular roads areas. The accident I had involved when I was parking the car and the drain cover was dislodged at the entrance to the garage. I hit the brakes as usual but the brakes were ineffective and I ended up crashing into my refrigerator and freezer in the garage which took the full brunt of the impact and were damaged. I hardly had any brakes at all and the fridges took the full impact. Luckily it was at low speed. So only the front bumper got cracked and got damaged along with the fridges being fully crushed in. After the incident I was so shocked at what happened and couldn’t believe I lost the brakes so I found that several other owners of the same vehicle has had the same or even severe brake failures. I was able to replicate the problem fairly consistently in certain roads where it was slightly bumpy or rough. I didn’t want to try in my garage for obvious reasons. Furthermore the emergency brakes and collision warning did not activate either.

Abs kicks on while going slowly over uneven, bumpy roads, or train tracks. The entire car vibrates and I cannot stop the vehicle even when hitting the brake as hard as possible. The car continues forward for a few seconds after causing me to nearly rear-end other vehicles stopped at a red light.

This is a known issue happening to Palisades and Hyundai isn’t acknowledging the issue. A braking issue has been going on for a while but hadn’t become a safety concern for me until this month. While braking but moving under 10mph, even less, the abs system will engage without warning when driving over bumps or somewhat uneven road surface. This includes speed bumps. This has happened to me multiple times but never caused me to be in harms way until this month. I was braking for a stop light on a road with numerous small potholes. As I was slowing to stop, the abs issue occurred. I braked as hard as I could but continued to get the push back/the automatic pumping action of the abs system and continued moving forward. The car was shaking as well. I continued pushing the brake/attempting to get the brake to engage the entire time, and my car finally stopped, mere inches away from rear ending the car stopped in front of me. I was slowing at a safe distance and would have stopped at more than a safe enough distance away if my car had let me stop. Now I’m deathly afraid of hitting a bump or some sort of uneven road when I need to stop and my car not stopping and hitting someone else, something else, or losing further control of the vehicle. No lights came on or any noises made to indicate a system was activated. My car also didn’t warn me of a possible collision and didn’t stop on its own, as it’s capable of doing. It’s as if the abs issue overrode everything and my car just wouldn’t brake. I’ve never experienced anything like this with any other vehicle, driving on the same exact roads.

Recently, the emergency braking system has been activated without warning on multiple occasions, including while driving on the freeway and local streets, even when no obstacles were present. This unexpected braking could potentially lead to dangerous situations, especially at high speeds. The emergency braking system unexpectedly activates without any obstruction, indicating a possible malfunction with the front sensor or abs system. The vehicle is available for inspection upon request. The unexpected activation of the emergency braking system, especially at high speeds on highways, poses a significant risk of rear-end collisions, sudden deceleration, and potential accidents involving other vehicles. The issue has been observed but not definitively confirmed or resolved by the Hyundai dealership, which suggested recalibration of the front sensor without assurance of a solution. The vehicle was inspected by a Hyundai dealership but has not been evaluated by other entities like the manufacturer, police, or insurance representatives. The issue occurred suddenly and unpredictably on various occasions. My experience is not an isolated case; I have found numerous reports from other Hyundai Palisade owners who have encountered similar issues, with no definitive solution provided. I urge NHTSA to investigate this issue thoroughly and instruct Hyundai to offer necessary repairs at no cost, given the potential risk to drivers, passengers, and others on the roads.

A severe safety concern with our 2023 Hyundai Palisade, which has been present since the day we received the vehicle. When braking on uneven roads, the brakes jitter and stutter. This issue does not seem to occur on flat surfaces; however, it is always at lower rate of speed when roads have bumps. On three separate occasions, I have experienced a complete loss of brakes, and my wife has faced the same issue at least five times. When this happens, standing on the brakes does not trigger any response—there are no warning alarms, and the brake system completely fails. The potential to hit another vehicle or pedestrian, or veer into oncoming traffic, is very high, and in fact, I’ve had to swerve into a curb (causing curb rash to the right passenger rim) to avoid a collision. Due to the severity of this problem, I no longer allow my wife to drive the vehicle. I have a appointment on 10/21 with mcdonald Hyundai. I have noticed this since day 1 and regret that I did not act sooner! upon conducting research, I discovered over 21 complaints on one website alone regarding the exact same issue. I am deeply concerned that the mechanics may not be familiar with this specific problem.

I was driving about 40mph on a sunny, dry day, and approached a red light. I depressed the brake, and rather than stopping, the brake vibrated and the car continued to coast an additional 2 car lengths. On a second occasion, about 2 months later, I was driving about 25mph on a sunny, dry day, and I came to an intersection. I applied the brake, and again, rather than stopping, the brake vibrated and the car coasted into the intersection. There was a car coming, so I had to honk the horn repeatedly to alert the other driver that my car was not stopping. I took the car to the dealership. They have been unable to reproduce the problem, so they insist that nothing has happened and they want me to take the car back.

I was driving over train tracks at about 5 mph when my car wouldn’t brake. I was jamming down on the pedal and that eventually triggered a really aggressive abs and emergency braking. I came millimeters away from hitting the car in front of me and the whole time it felt like I had zero control of the car and the car just had a mind of its own. Based on what I’ve read online I believe this is a known issue that Hyundai is ignoring.

I was slowing down approaching an intersection with cars already at a full stop up ahead. I was braking to slow down in preparation to stop. As I got closer, I drove over railroad tracks and felt the brake pedal begin to vibrate like the automatic emergency braking system kicked in. With my foot still on the brake, the car continued forward without any additional decrease in speed. I pushed my foot down as hard as I could and the car stopped inches from the car in front of me. I’m not sure if me pressing on the brake more even did anything or if some other collision avoidance system in the car stopped it before colliding with the car in front of me. There was beeping and the display switched to show cameras in front of the car, which happens when getting close to something while parking, etc. Luckily I was slowing and not at a high rate of speed. If I had hit the car ahead of me, there would have been damage but not major. What if I was going faster when this occurred? or if I was braking for a person or bike? or if it was collision avoidance that actually stopped the car here but I was the first car stopping in the intersection and couldn’t stop.

While in reverse the car is not alerting us to cars or people approaching or objects directly in kur path. I actually hit small fire hydrant that I could not see while backing up. I'm worried because I have young children and a busy street at time I would be devastated if I accidentally hit a person especially a child.

On four separate occasions, the forward collision assist turned on when a car in front of my car has moved over into a turning lane and they slow down. The car aggressively brakes, and on two occasions has come to a complete stop in the middle of the road, not allowing me to move the car until the warning goes away. I was nearly rear ended on two occasions because of the cars sudden aggressive braking. I called the dealer service number department and they told me they wouldn’t be able to diagnose the issue without trying to reproduce the issue which neither they nor I felt comfortable with. With the exception of the warning coming on during the event, there are no other warnings visible and the car returns to normal once it figures out there was no collision.

I have lost all confidence in this vehicle and my family, and I are scared to drive in (especially my 5 year old daughter). The mechanical failures that were experienced during these events were intense and life risking. During the first incident the vehicle brakes engaged while driving and caused the vehicle to stall in the middle of an intersection while turning left to enter highway, numerous vehicles were traveling in opposite direction and could have resulted in head on collision. No systems worked during this event, neither the horn nor the headlights worked to signal other vehicles of problem. Had to slam on the gas, which led to violent vehicle take off, that jolted my daughter around in her car seat and narrowly avoided collision with other vehicles. That was on [xxx], and similar events happened on [xxx] and [xxx]. Video and pictures of event were taken as they occurred on [xxx] event. Claim (case#: xxx) was opened with Hyundai consumer affairs on [xxx]. All videos and pictures were shared on multiple occasions with Hyundai team. Hyundai refused to repurchase the vehicle under lemon law provisions and cited that the issue didn’t start until the Feb 1st event, which exceeds the 12-month statute. However, the issues started in Aug of 2023 and the dealer service records clearly document this. Hyundai insists that since they could not replicate the issue it didn’t start until Feb 1, when they were able to replicate. I don’t agree with this view and should not be penalized because of Hyundai’s technical limitations. Furthermore, they were perfectly fine with using my family as guinee pigs as they instructed me to continue driving the car and bring it when it happened again. Completely dismissing the gravity and potential consequences of the events, as described above, that took place on [xxx]. This vehicle has proven to have major malfunctions and should be removed from circulation immediately. Hyundai claims the issues have information redacted pursuant to the freedom of information act (foia), 5 u. S. C.

When traveling at a modest rate of speed, if I apply the brakes going over any slightly uneven terrain the abs triggers randomly and makes braking really difficult. It takes longer to stop and much harder pressure. I have reported this issue to the dealer but per usual they "cannot duplicate ", however it happens very often and my dash cam has caught it.
