One problem related to strut failure has been reported for the 2003 Subaru Outback. The most recently reported issues are listed below.
Car is a 2003 Subaru Outback with around 60,000 miles on it. It is registered and driven in vermont year-round. The driver's side rear strut rusted severely which resulted in the lower spring mount to separate from the strut. This caused the spring to fall and come to a rest on the lower strut mount bolt. Fortunately, this did not result in an accident when it occurred however this is a concerning failure on a low mileage vehicle. I am currently in the process of having the vehicle repaired which will entail replacing the strut which failed.
