Forester: check engine light (and cruise light) on after replacing the timing belt. Mechanic says it is the catalytic converter and cost to replace is about $1000 (upstate NY)

Check engine light has been on for several years. Techs have told me I needed a new catalytic converter and yesterday one said that I need a new oxygen sensor to fix it. I will do neither because I understand that it is a reoccurring problem causing owners hundreds of dollars. I won't throw good money after bad especially since this issue is not affecting the operation of the car.

THE SUBARU DEALER SAID THEY COULDNT FIGURE A REASON FOR THE CHECK ENGINE LIGHT COMING ON. I DID NOT KNOW ABOUT THE CATALYTIC CONVERTER RECALL. MY GAS MILEAGE STARTED DECREASING WHEN THE CHECK ENGINE LIGHT CAME ON. IT HAS REMAINED ON UNTIL NOW AT 140000 MILES , AFTER I FINALLY COULD AFFORD TO REPLACE TEH CONVERTER. THEY NEVER ACKNOWLEDGE THIS FAULT WHEN I BROUGHT IT IN AT 44000 MILES AND I DIDN'T KNOW ABOUT THE RECALL THEN.
The check engine light has been on for a while and we are waiting to replace the catalytic converter until we are sure that will solve the problem. It is more an annoying than problematic at this point

Cruise was flashing and the check engine light came on at the same time. Dealership told me they replaced the catalytic converter; still under warranty so it was free.

Kept getting the "cat converter below threshhold" code several times over last 3 months(along with CEL on w/flashing Cruise Control light on dash). Didn't notice any performance problem or change in mileage. Went to AutoZone, used their code reader, and cleared the code several times; code kept coming back. Finally took to Subaru dealer to look at; diagnosis = needed new Cat Conv; checked O2 sensors, etc.; was told that it was definitely the Cat Conv. Replaced; cost of Cat Conv = $1100, plus $200 to install. Car does seem to run better. Not pleased, but satisfied that replacement was probably needed.

check engine light plus flashing cruise control light..... the catalytic converter was replaced by subaru because of being under warranty, but...less than 60,000 miles later the same problem has shown up again. this time no warrenty because the replacemnet part in only good for 12 months. now they (Subaru dealer) wants 95$ to tell me what another local mechanic has already diagnosed (for free) plus it will cost me 800-900$ for the part plus labor to install (approx. 1600-1800$.....come to find out my car will continue to run properly without this "new " part but, the flashing lights wil continue. does anyone know if this sensor can be disconnected?
