2020 Chevrolet Traverse engine problems

“The front intermediate exhaust pipe mounting bracket weld fractured at the engine manifold, causing the exhaust pipe to break completely loose. We can now actively smell raw exhaust fumes inside the passenger cabin while operating the vehicle, creating an immediate safety hazard for carbon monoxide poisoning and driver disorientation. Additionally, the heavy steel exhaust system is completely unsupported at the front, creating an imminent risk of the pipe falling and dragging on the roadway at highway speeds, which could cause a catastrophic crash. The vehicle began getting progressively louder during cold weather between late 2025 and early 2026. A certified Chevrolet dealership technician officially inspected the vehicle, filmed an inspection video confirming this exact structural failure, and attempted to submit it for warranty coverage. GM Corporate denied the claim solely because my VIN is excluded from Special Coverage N212356540, despite the vehicle suffering from the identical manufacturing defect described in the bulletin. I possess the official dealer repair receipt and the technician's inspection video as proof.”

“The contact owns a 2020 Chevrolet Traverse. The contact stated that the transmission was slipping and there was a delay while the transmission was shifting gears. The vehicle was sputtering and jerking while driving. While turning out of a driveway and driving approximately 5 MPH, the vehicle stalled. The check engine warning light was illuminated. The vehicle was towed to the residence. The local dealer was contacted and informed that there was no recall on the VIN. The vehicle was not diagnosed or repaired. The manufacturer was contacted but referred the owner back to the local dealer for assistance. There was no additional assistance provided. The failure mileage was approximately 150,970.”

“GM published bulletin PIP5681A on 10/05/20 regarding defective welds on the exhaust brackets near the catalytic converter. I had the same exact weld failure and GM is not honoring the warranty coverage, even though their bulletin said that all 2020 Traverse SUVs were included.”

“This is a know issue on 2021 models. The exhaust bracket is breaking away from the muffler/catalytic converter. The weld is breaking causing the exhaust to break away and both pipes must be replaced resulting in a 1500 repair. Why if it bad in later years is there no maintenance bulletin or mandatory fix for the 2020 models? It was repaired and fixed by McClusky Chevrolet in Cincinnati OH.”

“Flex pipe for exhaust is broken at 61000 miles rattles and makes noise upon start up and acceleration.doesnt make sense repairs for model years before and after 2020 are being repaired for free”

“Brakes have screeching noise Transmission jumps when changing gear The shift to park is so constant can not even go out because it takes more than 20 to 30 tries for it to accept park and turn Vehicle off! I have taken it to the dealer for the concern stated no recall or warranty At this point I am afraid to even leave it in shift to park and walk to the store and it gets stolen or leaves me stranded with my children”
