Since I've bought my car, at every car start up there is a noise or a rattle that is briefly audible for about 1 second then stops. When the vehicle is started again, the noise is no longer there. This only happens at vehicle start up. It sounds something similar to a winding noise. The engine in my vehicle is the exact same engine in the 2011 Toyota camry, 2ar-fe. A TSB has been filed for the camry however a TSB has not been issued for the Scion tC. My current mileage is 29800. I recommend a TSB be filed for the Scion tC 2.5l 2ar-fe so I and others with this problem could repair our vehicles. TSB for camry: TSB number: TSB-0146-10 NHTSA number: 10034924 TSB date: June 9, 2010 date added to file: February 1, 2011.
