The contact owns a 2020 Chevrolet Traverse. The contact stated that while driving at various speeds, the vehicle jerked abnormally and stalled. The check engine warning light was illuminated. Additionally, the message "Shift into Neutral, and Start Vehicle" was displayed on the instrument panel. The vehicle was towed to a local dealer; where the fuel injectors were cleaned; however, the failure persisted.

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.

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.

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.

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.
