My Chevy Cruze has a terrible Oder any reason it’s so bad that the smell will make its way into the house.
What kind of smell, burning, musty, moldy…?
kind of smell,
conditions under which it happens,
recent repairs if any.
Give us more to work with. It could be anything from a dead mouse in the ductwork to a banana peel under the seat to sulpher dioxide in the exhaust.
If you’re unable to identify the odor, let’s assume it’s gasoline.
So, park the vehicle outside the garage until the odor can be indentified.
Good suggestion. I second it.
