2020 Buick Enclave Engine

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

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. Reference: N252503850, N242445280, N222385510, N212356540, and photo attached.
