When the temp gets into the teens or lower gas leaks in and around the engine. This is dangerous!! I have found fuel near area that get very hot, and I am worried about my family starting on fire. Soa recalled a few years to repair this issue, but not all that are affected.

Engine light, failure of cruise control. Dealer replaced air pump (part #14828aa030) and engine control modulator. Dealer discount 50% "goodwill." Part was 4,611 out of warranty. One week later same problem returned, dealer states car needs oxygen valves and there is a national back order on parts. Subaru is offering the parts for free (indicating there is a known problem) but wants to charge labor ~$500. Parts may be unavailable for several weeks. First service failed to properly diagnose problem.

Head gasket leak on the driver's side cylinder head of a 2006 Subaru Forester X. mom's car (also a 2006 Subaru Forester X) has identical head gasket leak but on the passenger's side cylinder head. There is the possibility of oil dripping on the hot exhaust manifold. My car has had the head gaskets replaced under warranty. Her car is yet to be repaired.

The contact owns a 2006 Subaru Forester. The air bag control module fails to activate at least once per week. On each occasion, the passenger side air bag off light illuminates. The occupant detection sensor does not recognize a passenger sitting in the front passenger seat. The passenger side air bag also does not activate when the vehicle is started approximately once out of 20-30 starts. The contact's wife weighs 120 lbs and is 5'5 inches tall. She sits erectly with the seat back nearly vertical. The failures have been reported and investigated by the dealer and manufacturer. The manufacturer stated that the "occupant protection system is working as its designed intent and as such we are unable to recommend a repair or modification". the current mileage was 28,000 and failure mileage was 13,421. Updated 01/03/08 oil was leaking onto the exhaust system, the engine would surge and sag during slight downgrades with the throttle held just off idle and speed held constant, the speed control over and under shoots on slight grades, it would not go to full throttle, or to closed throttle when speed control was activated.
