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.

check engine light on, cruise flashing, another PO131 code on my 2005 Subaru

Check engine light on and cruse flashing. Code indicates O2 sensor.
My Check engine light came on so I took it to a mechanic. They ran a diagnostic test on my Subaru and it reported that there was an issue with the O2 Bank 1 Sensor 1. I have not yet fixed it as I am researching the best way to take care of the problem (this is how I found the recall).

This is the second time I have had to replace the oxygen sensor. First time was at 65,000. I bought my 2002 Subaru Forester new and maintained all the required maintenance needed to keep it in excellent condition.

check eng light, sensor fault code for front sensor.
2003 Subaru Forester139,000
P0032 check engine light code
dash light warning signals, fading radio, complete loss of dashboard, radio, speedometer and tach. Engine failure, and surge, then when I shut it off it failed to start. After a few minutes it started and ran fine until I got to a garage. No symptoms. Complete failure of everything a week later. The mechanic replaced the alternator, that he said looked new. I didn't know, but the previous owner had replaced her alternator before the sale. Now it's $1,000 + later, I find that another mechanic says it's the O2 sensors, and possibly the converters. This is a piece of Shit car. I will Never own another Subaru...EVER!!!!!!!!!!!!!
Check engine light on and cruise light flashing. It state red last year and I just failed my emissions test due to an oxygen sensor. Was not given code but I'm sure this is under the recall and I need help. How do is it determined that it's the front O2 sensor and I want to know how to get it replaced u set the recall. I don't have the money to replace this. Now my car is sitting on a private lot I pay for because as long as I can't pass the emissions test I can't even have my regular inspection stuck put on. This problem needs to be taken care of.
I had this problem since I bought my 2006 Subaru Legacy 2.5i Turbo while living in Oregon. People told me that it was probably because I didn't tighten the gas cap. And being that the car was bought new, I accepted that. And was also told in probably was either bad gas on because I was maybe running the car too low on fuel. After ensuring good gas and not running the car on low fuel, I still experienced the problem. I got it checked once at the Subaru shop, but nothing was found. I continued to have the problem off and on throughout the years from 06-16; only increasing in frequency the last two years. I recently used a scanner to check the car and it listed that I had an Oxygen sensor problem in Bank 1 / Sensor 1. I am currently in the process of looking for the cheepest way to replace both sensors due to being advised to replace them both.

Check engine light came on and stays on. Shop used computer to read and said it was the front 02 sensor, bank 1 sensor 1? IS this a recall on my 2003 forester?

Check engine stays on, OBD2 says o2 sensor & Idle control valve. replaced both, problem remains. Car surges, has trouble maintaining steady idle.
Check engine light comes on, when checked on machine says 02 sensor

I have front O2 sensor (Sensor # 1) failing and check eng. light. Diagnostic shows the #1 O2 Sensor failing. Problem has not yet been fixed. It is a 2004 Subaru Forester X2.5
Has not been fixed.....replaced exhaust....02 1 sensor 2
2005 Subaru Forester149,000
Just a guess on my part. Check engine light is on with blinking cruise. Sub wants to stall at idle and hard starting when warm.
