2018 Chevrolet Traverse

Shift to Park error occurs everytime I put my car into park. It does not turn off and the vehicle remains on until I jiggle the shifter. This has been "repaired" 2x under warranty. Now that it is out of warranty the manufacturer refuses to cover any of the expenses on this known issue with a bulletin per your website (18-NA-297).

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.

The transmission on my 2018 Chevy Traverse went out per the mechanic that recently inspected it. It was just purchased from a Chevy dealership not even 8 months ago. I first noticed the problem a couple weeks ago when my car hit about 25mph getting on the highway then wouldn’t go any faster as I would try to accelerate speed, then it was jerking and was harshly engaging from time to time. Then it finally felt like someone crashed into the back of my car it jerked so hard and then accelerated but only went up to 40mph and wouldn’t go any faster. It would hit 40 mph and then idol at the speed when you would hit the gas to accelerate. No engine light came on or anything at that time. Then a couple days later the shifter would be put into reverse and then not go in reverse when you hit the gas to go. Having two young kids, my husband told me it wasn’t safe to be driving it at all. We had it towed to a mechanic shop to be inspected since we depend on a car for our job. The mechanic inspected it with a diagnostic code reader as well as looking at the transmission. The overall condition is that the transmission is not working anymore. I have done research and for this specific make, model and year there are tons of recalls for the transmission.

I was driving on the highway and without any warning, the acceleration did not work in my car. I coasted to the side of the highway and waited for over an hour for a tow truck to arrive. Chevrolet replaced the transmission. I was told Chevrolet would consider rebates if I go through a Chevrolet dealership to fix it. They charged $2,000 over other shops, but only offered $200 off. They also took over a month to repair my vehicle. I wish I did not use them for repairs. Also, during heavy rains, the car leaked water through the electrical components in the roof. We intervened several times, but water persistently came through. Finally, we purchased the car at under 30,000 miles and immediately needed to replace the exhaust and shift to park feature. The car would not recognize when I was in park and could not turn off.

N222385510, the exhaust system separated from the car. There are current recalls from GM for 2019-Current Traverse models with the exact same issue. Our 2018 has the exact same problem and our local GM dealer verified it, but they will not cover this expense. We were quoted $2,000 + for the fix, GM Customer Care has been no help.
