The other day i washed my 09 special edition outback in the driveway and left it over night. In the morning when i started it a significant amout of smoke came out from under the hood. It smelled like something was burning but i could not find any evidence of anything that was burnt. I brought it to the dealer to have them look at it and they didn't find anything either. The car runs fine, all the fluids are fine end the CEL is not on. Has this ever happed to anybody? Does anybody have an idea what could have made this happen or where to take a closer look. I bought the car about 5 months ago from the dealer and got the extended warrentee. Its my 4th outback and i have never had anything like this happen to me.
