    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.
