2021 Chevrolet Traverse Complaints

Transmission shutters at lower gear going from 20-30 mph approximately and at the speed of 60-70 mph. When this happens it causes a delay in acceleration and for the whole car to shake. This was also noted by my mechanic even after changing transmission fluid and had concerns for the safety if it was to completely disrupt the transmission causing an accident. I was advised to check for recall since a lot of these makes and models have been having this issue. The SUV only has about 64,000 miles on it and has had all of its routine maintenance done regularly. I have only had it in my possession for 6 moths. No engine lights on. I do a lot of highway driving and I am concerned that this issue will possibly cause an accident. Ameritech Tire and Auto at 304-229-8924, Inwood, WV. August 12, 2026 was date of service.

The welding that holds the exhaust together has failed. They offer a Special Warranty to cover only the passenger side, however it has failed and exhaust is super loud. Also reading 4 codes from check engine alert. All are P0420 (cat convertor). The smell of exhaust and cat convertor is super disgusting

The contact owned a 2021 Chevrolet Traverse. The contact stated that the vehicle was taken to an independent mechanic for an inspection, where a leaking oil pan gasket was diagnosed. The contact stated that the failure had also occurred on a 2019 Chevrolet Traverse he owned. Although the vehicle had been taken to the dealer two months prior, the dealer did not find the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 72,400.

On [XXX] I purchased the vehicle from Bakersfield Hyundai within days I reported break failure and notified them about a noise that was coming from the SUV that sounded like a mini motorcycle, they first said (Xavier) that the noise would go away because it had just gotten serviced but they kept me there for four plus hours and said I had to take it back which I did and again I took it for break replacement and I told them the noise would get louder and sometimes it would smell inside the vehicle like vinegar again they did nothing they falsely said I declined to stay because of time Which I didn't I asked if they were able to provide me with a vehicle while mine could get serve since I have children that attend school to who they said no, so I couldn't stay longer I had to pick up my children from school this is my only vehicle so Hyundai would not do anything about the breaks nor that sound the vehicle started making beeming noises from across the dashboard the main screen freezes an...

Check engine light came on and I noticed that the cooling fan would continue running for several minutes even after turning vehicle off. Had a mechanic run the diagnostics and the code came back as a thermostat/cooling issue. Although when I called to make an appointment and told him the issue and that it was a 2021 Traverse, he knew exactly what the issue was. He said that is a very common issue in all 2021 Chevy/GM engines. Online research provided a couple special coverages for repairs on 7 different GM vehicles from that same time period. Of course, the Traverse is one that is not included. Seems fairly obvious this was a GM engine issue from all vehicles in the 2021-2023 timeframe. Not sure how they can only pick out 7 models, but I am hoping an update can be made to add the Traverse and any other GM models that have that same 2021 engine.
