Subaru Forester Problem Report
Subaru Forester 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.
the check engine light is on and it hesitates,i need to take my foot off gas and lowly climb speed,and while stopped at light etc it struggles to remain at a steady idle and often will stall, ive replaced both sensors twice, i have owned 3 subarus and if this prob isnt fixed a new wrx is NOT in the near future as planned where do i go for this problem, i just need the sensor i can install - Visitor

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. - Visitor
Both oxygen sensors are on code and cel is on runs cruddy - Visitor
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 - Visitor
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. - Visitor
Subaru charged me $425 just for the sensor - Visitor
Replaced air-fuel sensor. $450. - Visitor
02 sensor, cruise control light and check engine light came on after we had the head gasket fixed. Getting quotes on the price but initially told price would be $250+ from a local parts guy...hoping we can find it cheaper from another dealer. - Visitor
P0030 - A/F ratio (front oxygen) sensor heater failed. Seems the little heater on the sensor is only used when the car is warming up. Drove with it for 3k miles without any noticeable mpg changes. Finally replaced it with an OEM sensor at 181k. Real pain to change due to the tight spacing, the normal O2 socket does not fit. - Visitor
Had complete exhaust from Cat.to back done. A few days later Check Engine light comes on. Have it checked and its the o2 sensors. Had check engine light turned off and now my car barely runs. Feels as if its missing like on 3 cyl Of course the shop wants to charge me even though they were under it a few days prior - Visitor
I've had this happen twice now, only two years apart! The dealership said "oh, things just wear-out sometimes." It happened the first time with about 65k and the second time 75k. - Visitor
Same problem; all kinds of repairs done to exhaust. Just now learning of recall. Not yet resolved;engine light still illuminated. - Visitor
Subaru issued a recall (WWG-90) because the mass air flow sensor has a manufacturing defect.
Car been to Subaru shop 4 times in 6 weeks for this. Always comes up an evap code that gas cap...
Is the replacement costly (spprox), and what are ramifications if left alone?
