Had noticed a rattle every time when I start the vehicle.I got under and had located a broken front exhaust hanger. A few week later I noticed a different sound coming from under the vehicle. I go back to the under side and locked the exhaust flex pipe has now ripped at the front exhaust bracket. Mine being a 2020 isn’t coved by the 2019 or the 2021 special coverage. Chevrolet needs to fix this issue.
