2018 Chevrolet Traverse

The contact owns a 2018 Chevrolet Traverse. The contact stated while the vehicle was parked, the check engine warning light was illuminated. The vehicle was taken to a dealer where it was diagnosed that the emissions purge valve needed to be replaced. The contact did research and was made aware of Technical Service Bulletin Number: N232395300 however, the VIN was not included. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 60,000. 

The issue is with the Traverse Stabilitrak system. The Stabilitrak system controls, includes traction control, emergency brakes, tire monitoring, etc. as I understand it. The Stabilitrak lights has been intermittently coming on for several months. I took the truck to the manufacture and was charged over $1,700.00 to fix the problem. After the repairs, I picked up the vehicle and within three miles of the dealership the issue manifested itself again. The Stabiltrak system light usually indicates as the vehicle waits at a traffic light, and just as I accelerate for the signal change. The vehicle frequently stalls at that point, creating a rear end hazard, and a dangerous situation for me and other commuters. Upon returning the vehicle to the dealership, they claimed not to be able to identify the issue, that they initially charged me over $1,700.00 to fix. The said they could not recreate the problem, although it is a persistent problem that occurs within minutes of the vehicle operation.

bracket on the exhaust flex pipe bracket broke. This is a known issue by GM (PIP5681C) that covers 2018-2022 Chevy Traverse and Special Coverage notices have been issued for at least the 2019 (N212356540) and 2021 (N222385510). I called GM today and they said my 2018 Traverse would not be covered even though it is a known issue and had a bulletin issued on it. If this is a known issue for several years (including 2018), why wouldn't the 2018 model be included and covered?

The exhaust system mount bracket broken allowing exhaust system movement resulting in a cracked catalytic converter . The mount bracket broke due to a poor weld from the part supplier. The repair cost $2404.74 on 6/5/2023 at 33.953 miles . Recently I researched this issue and found GM policy # N212356540 on 2019 Chevrolet Traverse and Buick Enclave with exact same issue with coverage to 150,000 miles. My research also found that many other owners of 2018 Traverse complaining about the exact same issue with very similar costs. This obvious emission item should have been covered. l
