Does anyone else hear a ticking or ratcheting sound coming from the engine compartment when turning the car off? When I turn my car off and get out of the car, I hear this ticking sound that lasts for only about 5 seconds or so, and it seems quite loud. I知 thinking that it may be it may be the computer or perhaps the traction control unit or the power steering unit shutting down. But then again, I知 no mechanic or electrician to know what it really is. Anyone know what it may be?
