Buick
Enclave

Front exhaust flex pipes had to be replaced. It’s a common problem and a recall exists for the prior year.

I came to a stop in the left turn lane at an intersection with a red light with the car in drive and my foot engaged on the brake to wait for the light to turn green. The car suddenly and completely died and all power was shut down. I was not able to engage the hazards. It was dark outside and I was afraid cars behind me would hit me. It was an incredibly dangerous situation with no warning. I exited the vehicle and got to the side of the road. The police arrived and were able to push the car to the side of the road as well. I opened the hood and checked the negative battery terminal and upon pulling the lever, the power came back on. We have an appointment at a GM dealership on Monday to fix the issue to ensure we are not put at risk again.

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.

The chest clip does not stay fastened. It comes unfastened with a very slight amount of pressure.

Front exhaust bracket detached from exhaust. An issue that has resulted in a hole in my exhaust. This same issue has been identified and warranty extended for 2019 and 2021 enclaves with the same engine and exhaust parts. Dealership wants to change $1000 to fix the issue.

Welds have broken loose from exhaust creating a hole and loud noise & strong exhaust smell
