I have 2 Subaru Legacy's. Both have given me the same overheating problem at various times. This mimics all the symptoms of a head gasket leak. But the solution is ridiculously simple. Air gets trapped in the heater element, which sits under the dashboard and is higher than the radiator so that the air does not bleed out. There is no independent thermostat bypass in a Subaru. The hot water flowing through the heater element re-joins the main c...

At 150,000 miles, my Subaru Legacy developed a problem with the radio. Depending on my luck, the radio might or might not turn on. Eventually, the radio stopped working altogether, instead making a loud feedback type of noise. Subaru maintenance crew told me that the issue was electrical in nature and would cost upwards of $600 to repair.
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.
At 130,000 miles, the engine began to overheat. I could smell burning oil while driving and, especially, while idling. Subaru maintenance told me I had an engine fan failure and that I had to replace both fans at a cost of $600. I refused to replace the fans at that time and took the car to a different dealership, where I was told that the fans were working fine...

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.
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.
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.
