    This only happens in the first start up in the morning when vehicle is parked on a slope heading up. That means it would roll backward. The first time it sounded very loud and shaken up like the engine was about to fall off, today it sounded not that bad but sound like something running without lubricant!

    Anyone has any idea? it does not happen often though even I parked it on a slope. The slope is actually my drive way, thanks.

    1) is it a prime? (prime forum)

    2) if it is a 2012, the egr is probably clogged
