2018 Chevrolet Traverse

Shift assembly has failed twice - April 2021 and April 2024. For both occurrences, the vehicle spontaneosly stops registering when I shift into park. When I shift, the vehicle sends a warning to shift into park. There is a safety concern because I cannot determine whether or not the vehicle is actually in park. The GM dealer determined that the issue is a faulty shifter switch and harness and a faulty shift knob. Both were replaced. In April 2021 transmission shifter (part #84698649) and jumper harness (part #84733196) were replaced.

POWER STEERING ASSIST WARNING COMES UP. BECOMES VERY DOICCICULT TO STEER AND ALSO CAUSED STABILITY CONTROL TO BE TURNED OFF. EXTREMELY DANGERSOUS AS MY CAR COULD HAVE ROLLED AND KILLED ME OR MY PASSENGERS. AND APPEARS TO BE A MAJOR ISSUE, AS WHAT I HAVE FOUND ONLINE AND MANUFACTIRER/DEALER DONT CARE. PLEASE DO SOMETHING BEFORE PEOPLE START DYING/CRASHING BECAUSE OF THIS. 2ND CONCERN - SHIFTER......STARTS REFYSING TO GO INTO PARK. EVENTUALLY KILLING THE BATTERY. SWITCH IS ALL MESSED UP AND ALOT OF PEOPLE HAVE HTE SAME ISSUE AN DDEALER/MANUFACTRURERE REFUSE TO DO ANYTHING... THEY WILL FIX IT, AT OWNERS COST, FOR 700 BUCKS, WHICH IT ONLY TOOK ME 30 MINUTES, NOT 2.5 HRS LIKE THEY SAID.

The contact owns a 2018 Chevrolet Traverse. The contact stated that while parked or stopped at a traffic light, after releasing the brake pedal the vehicle failed to move. The contact had to wait approximately twenty to thirty minutes and restart the vehicle. There were no warning lights illuminated. The vehicle was taken to the local dealer however, the vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and referred the contact to NHTSA for assistance. The approximate failure mileage was 35,000.

On January 9, 2022 I was unable to release the parking brake. When I turned the car on, an alert popped up saying “service parking brake”. When I tried to release the parking brake, it would not release. It still made the sound as if it was trying to release but the parking brake was still engaged. I turned the car off and went back into my house for 10 minutes and then came out to try it again. Again, when I turned on the car, it said “service parking brake”. I tried to disengage the parking brake and it wouldn’t release. I pulled the button up as if I was setting the parking brake and pushed it down to release 3 times, with no change. On the 4th try, the parking brake disengaged. I received an email from OnStar Notifications informing me of the issue and directing me to take it to a service center. (Pic of email attached) This component has not been inspected by anyone. I would be willing to make the vehicle available for inspection upon request. This issue compromises safety because I have to set my parking brake, as I park on an incline and my truck rolls back a little each time I put it in park, or release the parking brake. It would be dangerous to leave my truck parked without the parking brake, but I can’t have my truck stuck with the parking brake on when I need to leave.

DUE TO THE EMS RECALL IT HAS CAUSED THE ABS TO MALFUNCTION WENT TO TWO DEALERSHIPS MORE THAN FOUR TIMES WAS TOLD TO PAY IN ORDER TO HAVE MY CAR FIXED DUE TO EMS RECALL SERVICE PROVIDER: DUE TO THE EMS RECALL IT HAS CAUSED THE ABS TO MALFUNCTION PER EMS RECALL THIS CAN BE FIXED FREE OF CHARGE. I AM BEING DENIED BY BOTH KILLEEN AND TEMPLE CHEVY DEALERSHIPS.
