2004 Subaru Legacy Problems

Check Engine Light Due to Failed Front O2 Sensor

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.

Radio Failure

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.
