Sigh... Ok........ So. I have this squeaky chirping noise in my engine I don't know where it's coming from ive already had parts replaced from my dealer, new tensioner, new belt, and water pump... And still the noise continues.. My dealership can't find it I can't find it, they tell me whenever it happens constantly just come to the dealer so they can look at it again... It's only happening now when I back up. Sometimes at start up.. Other than that it doesn't. DOES ANYONE HAVE THIS ISSUE?????
