2022 Hyundai Tucson electrical system problems

“Approximately one week after having my oil changed at a Hyundai dealership, I began experiencing intermittent collision safety alerts and multiple dashboard warning lights. On three separate occasions when I started the vehicle, warnings appeared for the forward and rear collision systems, along with multiple other sensor warnings and engine warning lights. During one incident while driving in traffic, the forward collision warning activated and the vehicle abruptly applied the brakes. I was nearly rear-ended as a result. I have taken the vehicle back to the dealership on two separate occasions. The dealership reported replacing a sensor, but the warning lights and collision system issues have continued to occur intermittently. I am concerned that the vehicle may unexpectedly apply the brakes again, creating a risk of a collision.”

“The contact owns a 2022 Hyundai Tucson. The contact stated that while driving at an undisclosed speed, the right turn signal indicator light failed to illuminate on the instrument panel upon depressing the turn signal lever to make a right turn. No warning lights illuminated. Additionally, upon depressing the turn signal lever to make a left turn, the left turn signal indicator light failed to illuminate. The contact stated that the failure progressed. While driving at various speeds, the brake lights failed to illuminate when the brake pedal was depressed. The vehicle was taken to an independent mechanic, where it was diagnosed that the wiring harness needed to be replaced. The vehicle was repaired. The contact associated the failure with NHTSA Campaign Number: 25V893000 (Trailer Hitches); however, the VIN was not included in the recall.

“My wife was driving my SUV while I was a passenger. We were in the left lane, and put the left turn signal on while traveling south bound approaching an intersection to take a left turn (traveling approximately 3-5 Miles Per Hour and slowing) at the traffic light (traffic light was green). There was a car in front of us that had stopped waiting for oncoming traffic to clear and make the same left turn onto the same road as us. While traveling in this lane we hit a deep pot hole (not very visible while driving), just as we were approaching the vehicle stopped in front of us. When hitting the pot hole, our SUV seemed to leap forward a bit and when the brakes were applied to slow and stop, the braking system failed (appeared to freeze) and the brakes did not work, and because the braking didn’t work, our vehicle hit the car in front of us. Prior to and after hitting the pothole, no audible warning sounds or visible alerts appeared and no emergency braking was activated. The airbags in our vehicle never deployed. Our safety (my wife and I) as well as the safety of the 2 passengers in the other vehicle were at risk as we all could have been injured in the accident.…”

“The contact owns a 2022 Hyundai Tucson. The contact stated that the check engine warning light illuminated and was cleared; however, the warning light returned hours or days later. The dealer had cleared the check engine warning light approximately 15-16 times. The vehicle occasionally stalled while driving at various speeds. The dealer diagnosed the vehicle with terminal engine failure. The contact was informed that the fuel system needed to be overhauled, and the fuel injectors and caps needed to be replaced. The vehicle was repaired twice. The failure persisted after the contact had confirmed the diagnosis with a certified mechanic. The vehicle was returned to the dealer, who replaced the engine. The vehicle was parked for several hours, and the contact attempted to turn on the headlights, but the headlights failed to illuminate. While driving the vehicle, the vehicle hesitated several times. The following day, the vehicle failed to start approximately four times. The vehicle was driven to the dealer but hesitated several times along the way and failed to start once at the dealer. The dealer diagnosed the vehicle and determined that the battery and other…”
