Subaru Legacy Problems
RepairPal has identified the most common problems with the Subaru Legacy 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.
Subaru issued a recall (WWG-90) because the mass air flow sensor has a manufacturing defect.
The leak may develop from the oil pump seal. Our technicians prefer to use thread locker when replacing the seal to prevent the bolts from becoming loose again.
A failure in the anti-lock brake system (ABS) causes the ABS pump to continuously run, which will eventually wear down the battery. An improved ABS relay is available to solve the problem.
