Prematurely damaged exhaust system. Identical to Special Coverage Adjustment N212356540 Front Exhaust Pipe but my dealer and GM says that my VIN it’s not coveted
Failed catalytic converter. I have had this part repaired multiple times and there is still a leaking issue. I have receipts from both auto repair shops and the dealership showing that this is an ongoing issue.
My 2020 traverse has the exact same issue as the 2019, and 2022 models, both of which have active recalls. I contacted Chevy and their response to me was that there was no recall on my model.
I took my vehicle to the shop for noise while driving. It was diagnosed as a cracked flex pipe. Upon research, the 2019 and 2021 models had recalls for the same issue, but not 2020. I did find a bulletin from gm including all models of traverse stating the cause could be a faulty weld. My vehicle looks the exact same as the bulletin. This is a safety issue as a hole in the exhaust can cause exhaust to backflow into the cabin. I'm very lucky and thankful me and my kids have not yet been medically affected.
Vehicle all of a sudden started sound loud when accelerating on a trip home. Vehicle is 58K miles. Upon investigation, the vehicle was loud when starting as well. Mechanic determined front pipe under driver side had rusted and broken. Was told there is no recall, not covered under purchased extended warranty - $600 to repair. This should not happen on a vehicle this age. There are similar complaints about the same issue for the 2020 model.
