Open the full vehicle complaint log (all categories)A smell of gas was present in the passenger area. I took it to my mechanic. He said the Damper Fuel Assembly (Part # 42086AE040) was leaking. It is a high pressure gas hose. Subaru no longer makes the part, making the car valueless. We tried junkyards, etc, but that part seems to be leaking on all. It is dangerous. I can drive it, perhaps, but the gas smell is in the body of the car. Subaru said it's "unfortunate" that the car that was worth $6-7,000 last week is worth nothing. Unless I want to drive it unsafely.
THIS WINTER WE SMELL A VERY BAD GAS ODER INSIDE THE CAR.
