I have a 2021 Chevy LTZ with the 6.2L and 10 speed transmission. Mine does the same thing. Every time I come to a stop it makes this chirping noise. I’ve had mine into 3 different GM dealerships and no one can figure it out. They tried replacing the exhaust valve next to the muffler, but that did not solve the issue.
