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.
2020 Chevrolet Traverse fuel system complaints
Page 2 of 2: complaints 11 to 19 of 19, newest first, as owners wrote them.
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.
According to General Motors, the new GM Special Coverage (N222385510) is only applicable the 2021 model year of the Chevy Traverse. The condition described includes the separation of the front mounting bracket from the front exhaust pipe. This happened to prior year models and are covered under a recall too. All years I searched as well as my mechanic. My vehicle is a 2020 and the same issue is present but has not been covered under a recall.
the exhaust broke, sounded like I was a race car driver. Muffle making loud noise while parking and driving
Faulty exhaust issues
The contact owns a 2020 Chevrolet Traverse. The contact stated that while depressing the accelerator pedal following a traffic stop, the vehicle failed to gain forward momentum. The contact stated the vehicle failed to exceed 15 MPH. The contact depressed the accelerator pedal and the engine failed to rev as designed. The contact stated that the check engine, parking brake and stabili-trak warning lights were illuminated. The contact was able to drive the vehicle to an independent mechanic who diagnosed the failure as insufficient fuel entering the engine from the fuel pump. The mechanic determined that the fuel pump needed to be replaced. The contact was advised by the mechanic that the failure was related to the federal safety agency Campaign Number: 20V639000 (Fuel System, Gasoline) and referred the contact to a dealer. The contact called a local dealer and was informed that the VIN was not included in the recall. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was approximately 40,000.
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.
UNKNOWN We were on the highway when we noticed the engine light come on, then the fuel gage went all the way to empty then back up again. We were going about 65-70 mph. I am taking my vehicle in today to get fixed
