I have an appointment to bring the car back next week as my schedule would not allow me to leave the car with them this week.
Let me know what your local dealership finds, in case the problem ends up being something else. |
THANK YOU. EDIT: Do you know your build date? Mine is 5/25/23.
I think others have had this performed and the sound came back.
Still seems weird that it sounds like an exhaust leak . . .
I will for sure update this thread after friday.
