Q: Rattling noise when car is idle

asked by on

Car makes rattling noise when stopped but goes away when I accelerate? What could be the cause.
My car has an automatic transmission.

Hi There, Depending on the sound of the noise and where it is coming from, this may be something like a heat shield underneath the vehicle which is a part of the exhaust system. These are commonly known to rattle or vibrate as they become loose and produce a bit of a rattling sound that tends to go away as engine RPM’s increase. I would suggest having a professional from YourMechanic come to your location to take a look at your car to properly diagnose the sound.
