Check Engine Light Due to Failed Front O2 Sensor on Subaru Forester

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.

Bought the car from a dealer who obviously reset the light because it came on within 60 miles of ownership, so the mileage above probably isnt the most accurate.

Flashing cruise light and check engine light always on. Subaru dealer said not a problem and disconnected the engine, only to have it turn on again one week later. Now knocking hard, vibrating, when driving, and accelerating. I am now told its the o2 sensor.
Both oxygen sensors are on code and cel is on runs cruddy
Check engine light comes on and off. Typically on during longer drives above 45mph, will turn off every now and then if driving slow. Took it to the shop-bad O2 sensor $380 charge at Subaru dealer
My engine light is on as well and I am not happy that it looks like I am going to have to pay for a recall that is clearly Subaru's fault.
