hi I am new to this site and I have not seen a post similar to mind so that's why I'm posting. I have recently went into my local Subaru dealer for the 105 K mile maintenance. They replaced my timing belt, serpentine belt and alternator belt. I also had an oil change and all four brake pads replaced.During this time they do their courtesy multi-point inspection. They also did a courtesy computer update. Which we did not ask for or give permission to do. Anyways after receiving the car back my wife went out of town for work not 10 miles out of town the check engine light turned on and the cruise control light started flashing. As soon as this happened the cruise control no longer worked. We called our local Subaru dealer and told them what happened they said bring the car back and take a look at it. Mind you this car has a 110k on it we have never once had an issue with it ever. Now after I drop 1200 Into it for scheduled maintenance does Subaru dealer says now we possibly need a new catalytic converter and they said the computer update they cannot warranty if something went wrong with that it's kind of on us. I'm not a Mr know it all but the little bit I do know about cars is catalytic converters just don't all of a sudden turn off or go out they show symptoms and slowly go bad from my understanding. Granted this just happened a few days ago and they are still trying to figure out what exactly is going on but I am extremely frustrated and I'm wondering if anybody else has had this problem. If so what was the answer or the solution. Thank you for reading and thank you for any and all input!
