I bought a new, 2007 Subaru over a year ago. I only have 15,000 miles on it now due to my short, 5-mile drives to/from work. When I bought it, it had a problem. After driving it until it was hot, it would stink like something was burning off from under the car. We would notice this when we stopped. When we took it to the dealer, they said that was normal and would go away after a few long drives. Well, a few long drives (up to 3 hours) later, it still stunk. This went on for months. The dealer finally admitted that there was something sprayed underneath (rust proofing?) that still had to burn off. It finally did, and it doesn't stink now.
But, I want to know if anybody else had this experience. Did you? If so, please post.
