The front exhaust pipe bracket has broken. Upon investigation, this is an ongoing issue for 2018-2019, and 2021-2023 Chevy Traverse and Buick Enclave models, but NOT 2020. All of the models use the exhaust system and same bracket, and it should be included as a special coverage. In fact, the attached picture of my vehicle will show that it is an identical break to those pictures used in the previous bulletins. Any help is appreciated.

We bought this 2020 Buick Enclave from Pinegar Chevrolet in Republic, MO from the preowned side of the dealership. When we test drove it only in the parking lot it didn't make any noises, but as soon as we drove off the lot after purchase the brakes made a noise as if the anti lock brake system was not working properly making it difficult to stop as the car should. We also was told that since this is a preowned and not a certified preowned that it was sold as is no warranty. I believe GM needs to fix this issue ASAP or the dealership needs to either buy the car back or put us into something with a warranty that doesn't have safety issues. We bought this as our family vehicle and I don't believe it is road worthy or safe to be transporting my family in.

Bracket holding exhaust pipes broke and I'm told it is a hazard. It is over $400 to fix it, I paid almost $6,000 for warranty service contract when I bought my car which doesn't cover it. It looks like this same problem is listed for 2019 but not 2020 which would have covered it if you would list it as a problem for 2020 also.
