They actually did this with the recent emissions recall for automatic 1.4T Cruzes.If I'm not mistaken, early Cobalts had issues with P0420 codes being set and having cats replaced. Around 2008 they issued a tsb I think calling for reprogramming. The cats were fine... Could be the same situation maybe?
18,000 left on emissions (80,000) and 38,000 left on power train (100,000). B2B died 26,000 miles ago (36,000).Hi I have the same problem pop up days ago. I have 2013 cruze ltz with the p0420 code. I called my nearest dealer (62,000 miles) I told them the code and they said they couldn't tell me unless I brought it in. they said it was going to be 152 diagnosis charge too if it wasn't cover by warranty which I believe I missed it by 2000 .

I would agree with you - and it's likely that running rich has slightly degraded the cat converter's performance.I had this same issue happen recently. The check engine light started going on and office at about 94k miles. Took it to Autozone and they said it was a problem with an O2 sensor. The light finally started staying on at about 99k after a regular dealer service. They checked it for me because they thought it was the dip stick or oil filler cap. They said it was the "catalytic converter not operating at proper efficiency". I also have been playing "service tag" trying to have the most recent recall performed. I work out of town and can only get service done on Saturdays. My dealership is great about working with me and we are trying to get the recall done when we can both be in the right place one Saturday.
The reason I bring up the recent recall is because it is for the engine running too rich at higher rpms and wot. I'm wondering how this affected my catalytic converter and if it contributed to it's premature failure to meet proper efficiency? I know it's not the fuel as I always buy my fuel from Shell and use only premium octane. I think it's the rich mixture causing it due to my daily commute. I drive 90 miles one way on and off highways and turnpikes meaning I am accelerating at very high rpms and sometimes wot daily. I think that GM should replace the cat and/or O2 sensors due to their failure to properly program my car in the beginning and I will be bringing this up to the dealership once I can get an appt. to have the recall performed. If I get no joy from the dealership I will be moving on to GM directly.
My only other option is to remove the cat completely and apply a "tune" that eliminates the requirement for the reading that throws that code. I am certainly not paying $400-$800 to have a cat replaced when I can spend that money on a tune and get better performance.
I just got P0420 Saturday night. My guess is the catatlytic converter needs replaced, but I'm not sure. It seems like my O2 sensors are working as they should. I took a video of my UltraGauge monitoring:Some interesting reading about P0420.
I believe you can graph the mV signal of both the front and rear oxygen sensor using the Torque App.

Robby, if I just had a major engine repair done under warranty with a vacuum leak causing the engine to run rich, then that could have caused the early failure. Come on man, I've owned 100 years + worth of cars and never heard of a cat converter failing. LOTS of other parts fail like O2 sensors, but not this. Something caused it.Not really a timebomb.....cats fail as a result of something, often fuel (quality) related, sometimes a result of a one time occurence such as a extreme case of fuel flooding.
Speculation abounds and, in the grand scheme of things, I'll bet far less than 1% of the entire, catalyst equipped vehicle population ever has a problem.
Certainly not the kind of thing to frett over......unless you are the unfortunate soul that has the failure.
lol there isn't a listing for a car this new because IT's NOT SUPPOSED TO FAIL lol. You guys are helping a lot. God, how I love the internet. There is no new problem known to man. Am going to have fun down at the dealership tomorrow while they explain how the catalytic converter in a 3 yr old car needs to be replaced and that it has nothing to do with the engine repair 3 months ago.Brian-
Don't go scaring people. You're talking about emissions in California. If you're in California emissions regulations suck it's one of the worst in the country.
Cat's are in the rockauto catalog, and while some can't be shipped to Cali because they don't meet California emissions they can be sent everywhere else.
I don't think there's a listing for a car as new as a Cruze. The only option now would be to try cleaning solvents in the gas tank or possibly a used cat via a salvage yard. Maybe there are regulations imposed in certain states about the sale of this "emission component" in the secondary reuse market.
Not sure but not worried about it either!
