What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
A check engine code p2138 also occurs as the throttle looses connection. The problem is most evident in winter months with higher humidity and high temperature fluctuation.
I called my location deaer in traverse city michigan over a year ago they said they would put me on a waiting list have not heard from them over a year ago on the passenger air bag recal
Fuel leaks around clamped rubber hoses in and around intake manifold especially during cold weather. The fumes from these leaks are extremely noticeable at slow speeds or stopped and enter the drivers compartment through the vents. I have great concern for the possibility of fire.
Takata recall-have been waiting 4 months-no one can sit in passenger seat. No parts available? I think 4 months is long enough.
Examples which cause this are small to large potholes, cracks in the road surface, driving with one tire on the painted line in the road (very noticeable surging and can be scary when the road is wet), sand or gravel on the shoulder of a paved road effecting one side of the car only, puddles, slight snow/slush cover,…
Strong fuel smell in cabin when started in very cold weather and persisting even once car has warmed up. So severe as to cause nausea and fogging of interior windows. Had to drive in very cold weather with windows down to vent fumes.
The windows will fog up from the fumes being sucked when the heat is on. This problem has been occurring every winter all winter for the 4 years that I have had the car. The car only has 50,000 miles on it.
There is a risk of fire and intoxicating fumes. These vehicles have a history of this problem. Subaru has not and will not make a commitment on a recall. 2005 and 2006 bajas have had a recall for the same problem, but I cannot get it fixed because mine is a 2004.
