2004 Subaru Outback Problems
RepairPal has identified the most common problems with the 2004 Subaru Outback based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
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.
A vibration or shutter may be noted on acceleration. If the transmission torque converter is suspected a revised part is available to correct this concern.
