2022 HYUNDAI TUCSON HYBRID Service Brakes Problems

All warning lights and audible alarms started going off at the same time. EPS, ABS, Auto Hold, Collision warning, Air bags, All wheel drive, brake system, and more.1st time it happened was [XXX], while driving. The car was drivable but I did notice a difference in braking and acceleration. I parked and turned off the car. I did turn the car back on several times and the alarms continued. I finally turned it off for 10 min, and all alarms stopped, but the check engine light stayed on. Car sat overnight and all warnings had stopped. Took it in for service, and issue could not be duplicated. 2nd time it happened was [XXX]. I had to have the car towed since it would not move when in drive or reverse. Alarms were still going off when it made it to service. They replaced the brake harness. 3rd time happened on [XXX], 3 days after the brake harness was replaced. Towed it to service and they replaced the engine harness. 4th time was on [XXX], 2 weeks after engine harness was replaced. This time there were no audible alarms, just all of the visual ones. Same performance issues as stated before. This issue seems to have happened to several other Hyundai owners as well, as per complaints in Reddit and on Hyundai forums. There does not seem to be a consensus for what is actually causing this issue. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The blind spot warning went off and locked all the brakes up. We were not able to move the vehicle and could not even pull off the road out of traffic. There is no way to disable the brakes when the computer or sensors are malfunctioning. We had to get the vehicle towed.

I wasn’t even allowed to select all the issues I’ve had with this vehicle since day of purchase three years ago June, and upon picking up the car I have had issues. My leather seats have bubbled up. My car will not merge. It will suddenly accelerate my car drops down in the middle of the road. My moonroof opens on its own. My car windows were randomly roll down on its own. My car breaks itself. My car emergency brake won’t unhook my car. Every single light is now on it. They have attempted to fix numerous times and my life has been put in jeopardy and my child’s life numerous times. No one can fix this issue. I am now told her I will have to wait three weeks for a rental because everyone’s backed up in diagnosing these cars. This car is going to kill me in my child and is a safety hazard. It does this stuff with lights on and without and it’s random and no warning my EV warning has come on my brake system. Warning has come on my car has been unable to stop and coasted and suddenly was able to then stop.

This relates to an Intermittent Braking Anomaly that started occurring within 1 year of this Hyundai Tucson Hybrid Ltd. purchased "New" in Aug. 2022. The 1st Service Invoices (Jun23 & Dec23) only reflected "Customer Requests Complimentary Maintenance Plan Tire Rotation," but did not reflect the braking anomaly; eventhough the braking anomaly was discussed with the Service Advisor at those times. There have been at least 7 Service Appointments that this braking anomaly was identified by the vehicle Owners to the Service Advisor. This has been, and is, an intermittent anomaly/problem that occurs most often when slowing down to stop, and especially when going downhill. There is a very noticeable "Shaking/Shuddering/Pulsating" recognized by the Driver, and when present, Passenger(s) also. On average, this occurs 1x/week , and inconsistent. One time it started pulling left towards oncoming traffic. Another time it was violent shaking, and almost unable to stop at stop sign. The Dealership 1st attempted to repair this by refacing front rotors in 2024. This did not fix the anomaly. In Dec 2024, returned to the Dealership, and a Tech. was able to duplicate the braking anomaly. With that, they then replaced both Front Rotors (51712-L1100 Disk) and Brake Pads (58101-P0A011 Pad Kit) in Jan. 2025. The braking anomaly continued later that very same day the Front Rotors and Brake Pads were replaced! Returned to the Dealership the next day and discussed this braking anomaly with the Service Mgr., and He and the Service Advisor drove it for about 15 minutes but were not able to duplicate the intermittent braking anomaly. Both Service Mgr. and Sales Mgr. suggested to buy new vehicle. Returned to Dealership in Feb. 2025 for about 2 weeks for them to again evaluate. They were unable to duplicate the braking issue after several test drives and multiple individuals driving. This anomaly continues and neither Hyundai Corp. nor Dealership will do anything else to solve this anomaly.

A week ago, I was driving my 2022 Tucson Hybrid Limited on the highway on my way to work around 7:50 a.m. It was a bright day, good weather. I was in the center lane when my car suddenly braked HARD and came to a stop on the highway! My foot was still on the gas pedal, but the Automatic Emergency Braking light was on. I panicked because I had no control over what the car was doing. Thankfully, I was not rear-ended and didn't cause an accident. I put on my hazard lights, shifted into park on the highway's center lane, then back into drive and it seemed fine. There was not really any traffic in front of me that I remember, but there were some cars on either side and behind me that had to swerve around me. I don't trust this car anymore. It is going to get me or someone else killed. I took it to the dealer 2 days ago and the initial inspection didn't show any problems or error codes. They told me I could have it back since there didn't seem to be a problem or they could give me a loaner car and keep testing my car. I have a loaner. I hope they find something wrong with the car, otherwise, I am afraid of my car getting me or someone else killed. I am especially scared after reading about all the others here who have had this same issue.

On multiple events brakes would not come to a full and complete stop. Many close calls of not being able to stop quickly on the highway or going down hill. The problem has been reproduced by the dealership. No warning messaging.

I turned right into my driveway at a slow speed. As I went onto the driveway, the car surged forward. To avoid driving into the garage door, I turned to the left to drive along the side of my house thinking I would be able to stop it. I kept hitting the break but the car kept going. When the vehicle did not stop, I steered to the right because I thought it could be possible that my neighbor's dog could be in the adjacent yard (to the left of my house) The ground between the houses is pitched down (to the left) towards my house and I side-swiped the back half of the side of my house. Although applying the break, my car continued after sideswiping the side of my house with the front right side of my car and went into the house behind my house causing damage to that house. My car stopped when it went into the house behind my house.

5/17/23 took vehicle to Dick Smith Hyundai for navigation issue, after being asked to park in a different spot brakes failed and car crashed into one of the dealer cars. Since owning the car for over 14 months without any brake issue I thought maybe my foot slipped off the brake. When leaving the dealer I tried braking several times with no issue. 5/26/23 while parking the car at a restaurant the brakes failed me again and was obvious not a slip off the brake that caused the car to collide with a tree saving me and my wife from falling down a steep embankment. Severe damage to front of car. 5/27/23 Called Dick Smith Hyundai to ask about how to remedy an obvious safety issue with the brake, was told that they would not check it out until body repairs are made first and if the issue could be duplicated before Hyundai would be involved. There were no warnings of brake or other issues. This vehicle is UNSAFE to drive after body repairs are made it will have to be towed (at my expense) back to a Hyundai dealer. Police reports on both incidents, GEICO claim put in also. No other inspections at this time. this happened in Greeville SC which is our summer home,

The car slowed down so I tried stepping on the gas pedal and noticed it wasn’t working, then I tried stepping on the brake pedal and it didn’t work neither. The car slowed down and called it to get towed.

My vehicle takes over my breaks and completely takes control of my vehicle away from me (the driver). It does this randomly. I had a hit and run in a parking lot due to this issue. I am greatly concerned for my safety.

Thankfully we are alive. We were going at speed and he attempted to pass me on the median, grass and rumble strips. He was inches away from my rear bumper, riding me. When I put the turn signal to move away from him he hit my driver’s side rear panel (side swiped), thank God it didn't turn into a pit maneuver and killed us. He then proceeded to take off. So one thing I have to say is, the vehicle has great pick up. I called 911 and went after him to get his lic plate. When I got to be about 10 car lengths or so, he slammed his brakes. Since I was on the left lane, I could not keep going left and risk going into oncoming traffic. Plus, there was a car on the right lane I slammed the brakes and rear ended him on his right rear. He had a 2021 Toyota Tacoma pick up and our hood flipped up and shattered the windshield. The hood stayed up and I was driving blind. All I did was keeping straight, not knowing where I was going and didn’t hit a vehicle, tree, embankment or sign. I went there yesterday and I have no idea how I we didn’t die. I’m so shaken up by it. When we came to a stop, there was a hole about 6 feet from my front tire. We were the victim of road rage and this person caused the accident purposely. He admitted it to the police. He said to the cop, I was slowing down traffic. I suspect with the size of his vehicle and being so close to my rear bumper, he did not see my turn signal. My major concern is the airbags did not deploy and the hood flipped open blocking my view. I was in a forum and this happened to the same model owned by someone else. I suspect this is a design flaw.
