We had this problem on 1999 Impreza and now have same problem on 2000 Forester.
Forester smells like burnt rubber from front end after a 20 mile drive. Everything appears OK under hood. Belts, hoses, wires, etc. all OK. I have checked for leaks on or near exhaust and come up empty. Had the same success at finding smell on the Impreza. I have seen others mention this on this forum, but never found the cause. Any ideas?
Thank you! DAW
