I was told by 2 dealership and a TSB is issued that the noise is from the High Pressure Fuel Pump. They even show me the paperwork on it.
Only problem i had is we started up a New 2011 LLt and it didnt have the same noise?
My noise is very noticable at idle and when the gas is pressed goes up slightly.
I dont wanna bring it into another dealership because even tho car is under warranty they are charging $90 to look at it.
