I get sort of a rattling noise, like something is settling maybe it could be air or something it's hard to describe. The dealership said it was nothing and it just was the exhaust rattling, the heat shield or something. Could that be like something loose maybe with my BOV or even something weird to do with the exhaust since my exhaust sensor is gone, I got a CEL from that, they're going to be replacing that. Basically I"m asking does anyone else get any strange noise when they shut the car off? Thanks.
