i have what sounds like an exhaust rattle coming from the rear passenger side of my 2008 2.5i. it is a low-pitched rattle, and it goes away when i release the gas pedal. happens maybe 4 or 5 times for every 30 minutes of driving.
any tips on how i should deal with it or what it could be? my car is still under drivetrain warranty for about 15 days, should i take it into the dealership?
