Bought a 2011 LTZ for my son, drove out to the dealer to get a spare key, come out start it up and I hear a change noise. It's slower than the engine speed and kind of a wah, wah, wah (once per second).
Next day I invited my brother over, found out the engine needs to be warm before the sound starts.
He doesn't have a clue either, says ask a Cruze forum.
So hear I am.
Can anyone help?
