2004 Subaru Legacy Problems

Subaru Front O2 Sensor Recall

The front oxygen (air fuel ratio) sensor element may develop a crack, causing the Check Engine Light to illuminate. Subaru has recalled certain models to replace sensors that may fail. The Subaru service program number is WXW-80, this is not a government mandated recall.

Blown Wheel Bearings

My Subaru Legacy experienced three blown wheel bearings. Each time, the car would develop a droning noise, which would get progressively louder with continued driving. A fourth was in the works when my engine blew due to a leaking head gasket. Each wheel bearing cost $450 to replace.

Passenger Airbag Inflator

Moisture sensitive airbag system components may deteriorate in humid climate regions, causing an increase in inflator pressure which ruptures when passenger airbags are deployed. Injury can result from inflator parts striking an occupant. Dealers will replace affected airbag inflators to correct this concern. Subaru is the manufacturer of Saabs affected by this recall. This recall supersedes Subaru recall 14V-471.
