2022 Hyundai Tucson Hybrid

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)

While driving, my entire dashboard lit up with every warning sound and symbol for the car. It would cycle through collision, airbags, braking, all of it. Luckily I was able to drive to a safe place. I let the car sit overnight and the alarms stopped. Took it to service and they could not recreate it and no codes showed up. Second time it happened, the warning sounds and lights didn’t stop. The car would jerk when I tried to put it in drive, so I had it towed to dealership. They have video and photos of it. After 2 weeks, they said it was fixed-a pin in a connector was bent. Had car for 3 days and it happened again. Had it towed again. They have had their ‘senior’ techs looking at it, and none can figure it out. There are Reddit posts with this same issue, as well as Hyundai group sites.

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.
