2020 Hyundai Palisade brakes problems

Filed Jul 20, 2026 · Brakes, Engine · TX

When attempting to use engine braking to control descent on mountain roads, the vehicle failed to slow. Engine RPMs increased and speed increased requiring significant brake usage. Last year the vehicle performed as expected as deceleration was controlled via downshifting with much less brake usage. The only change was the application earlier this year of Hyundai service campaign 9C9.

I was recently involved in an accident with my 2020 Palisade that I believe may have been caused by a brake failure. I was simply moving the vehicle from one part of a driveway to another when, as I drove over a drainage ditch, the brakes did not respond and the car suddenly accelerated into a tree. I sustained facial injuries and was transported by ambulance to a nearby hospital. The vehicle is currently at Canby Motors in Bel Air and is available for inspection. The vehicle has only been inspected by Canby Motors to my knowledge at this time. There were no warning lamps, messages or other symptoms of the problem prior to the failure.

Passenger side rear brake caliper failed causing the brake to scrape into the rotor. The emergancy brake remained in the lock postion when the caliper failed. Locking the caliper in the up position and releasing brake fluid. Driver side brakes, caliper, and rotor completly intact and does not need replacing.

When driving our brakes are spongy, downhill braking control gets disabled and tells us to control our speed even when going speed limit and below. Increased braking distance is needed, brakes are to the floor. When taken in for this concern we were met with, no issues noted on inspection. The brakes are getting worse and we feel as though this is a hazard for driving.

On February 2024, I took the SUV to Lynn's Hyundai for an issue with A front sensor or the braking system - The problem is when you're driving at times very often in the streets, the vehicle will automatically cause the brake sensor to go off the dashboard with light up and the brakes will engage causing the vehicle to jerk hard and or stop at times and I have a huge concern that this may cause a serious accident. I was told by Hyundai service department, that perhaps were driving to close to other vehicles to cause this, but it happened several times when there are no vehicles or objects present. Apparently they had no interest in resolving this matter, they claim that the system test showed no duplication of said issue, vehicle was taken on a road test and they found no issues, The recall were all fixed, and I was called to pick up vehicle. I drove a few and the braking started again, so I pulled over and started recording to see if happens again and I was able to catch some of this problem on video. This has caused my husband to lose control of the vehicle causing him to hit a cone on the road. Your immediate help with this matter would be greatly appreciate.

[XXX] - Driving from San Diego to Ventura County (home), my dash flashed something to the effect of "Emergency Braking System Malfunction" as my brakes were engaged while driving 65-70 miles an hour (no vehicles close in front of me or on either side). This was VERY scary and could have caused an accident if there had been vehicles closer. Usually when this system j=kicks in you get a Collision alert alarm, then braking initiates. There was no collision alert either. [XXX] - Took vehicle in and Hyundai said they could not recreate and had me take vehicle home [XXX] - Same thing happened on my way home from camping (emergency braking malfunction and brakes engaged while no vehicles around and nothing in front of me). This time the warning light (Triangle with "!" in middle and a number 1 lit up on dash and stayed on until I turned car off (I have a photo). [XXX] - Found this issue reported by multiple people on Hyundai online forum (emailed to manager at Alexander Hyundai). [XXX] - Took vehicle back in. Manager said he would check cameras as he believes this has happened before and they had to replace cameras. [XXX] - Dealership called and said can't recreate and want me to pick up car. Told them this is going to cause a bad accident and they will be liable. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

So there I was, stopped at a red light, waiting for traffic to clear and about to turn right. Traffic clears. I step on the gas. Nothing. I look at my dash and there are no signs of life. No warning lights, no bells or dings. The vehicle is just dead. I’m pushing the start button, pushing gears, tried to turn on my hazard lights. Nothing. As expected, the symphony of horns from vehicles behind me started. So I pull the lever from inside to pop the hood, open my door, and exit the vehicle. I get the hood up and first thing I go for is the battery. I reach for the battery cable and it’s loose. Twist it a bit and viola! Car starts up! But then I realize the car is rolling backwards! Ahh! So I run and jump into the moving car and put my foot on the brake and stop it. There were two saving graces here: 1. The road I was stopped on was mostly flat. 2. When I exited the vehicle I left the door open. Nobody was hurt. The vehicle didn’t hit anything. But had there been in incline on the road, I may not have been able to catch up with the vehicle and stop it. And had I closed the door, it probably would have been locked when it restarted and I would not have been able to get in. IF THE BATTERY IS DEAD (or in my case, a battery cable comes loose) THERE IS NO WAY TO CHANGE GEARS! Should this happen again while I’m alone in the vehicle, I’d have to wait, a prisoner in my car, until some good citizen came along and ask them to open the hood and jiggle the battery cable. Not as dangerous, but should the vehicle be parked in a single garage and then the battery go dead (for whatever reason) one wouldn’t be able to put the vehicle in neutral and push it out of the garage to get it jumped off from another vehicle. HOW DO YOU PUT THE VEHICLE IN PARK with a total loss of electrical?

On 1/24/2023 I was driving down the road from my home to go to work when, as I was going down an incline, my brakes started pulsing and I lost all braking ability. I drove thru a stop sign, into the intersection and was able to steer the car down the road. It was down a hillside. I was able to eventually stop the vehicle approximately a mile and half from where the brakes failed. I was instructed by the dealership to have the car towed to them so they could evaluate what happened. I did this. The dealership is trying to assess what happened. After 1 week, they replaced all 4 tires, did an alignment and replaced a leaking rear shock. The vehicle had 36,201 miles as of 1/24/2023. The dealership claims that the wear on the tires and the vehicle being out of alignment caused the wheel speed sensor to misread the speed and triggered the ABS to unlock all brakes. When this happened, all the warning lights for the braking system came on: ABS, Auto Hold, Traction Control, Forward Colision Avoidance System, Downhill Descent Control. I had nothing to stop me. Thankfully, no other vehicles came thru the intersection when my vehicle lost control. The dealership has, after a week, supplied me with a loaner vehicle. They are trying to duplicate the loss of brakes and all the lights that were activated when I lost my brakes. I also mentioned to the Service Manager at the dealership that I have repeatedly been asking the technicians to check the tires and to rotate the tires at our last few service appointments and had been assured the tires were fine and the tire rotation would be done. We normally have the tire rotation done every 7,000 miles due to the fact that it is an AWD. If this had been done as we requested, how could this happen? Wouldn't someone have noticed uneven tire wear? Our major concern is that when the brakes fail, you have no backup braking system in place. Is there something wrong with the programming for the electronic braking system?
