In cold weather (low 30s) when at idle, there is a strong burning oil smell that comes out of the dash air vents. Some days it happens consistently and other days it may happen once. Of course you can’t make it happen on demand and the dealer said there are no oil leaks when inspected. The first winter we owned it is when it started. It went away in the Spring, and now that it’s winter again the strong fumes are back. It’s not an exhaust or antifreeze smell. It definitely smells like oil burning.
