I picked up my brand new cobalt last thursday, drove home when my yellow engine light came on. Brought it back to the dealer on friday morning, they said it was a faulty code, reset it, again it came on during the ride home. Brought it there today and I guess I need a new catalytic converter, part should be in in about 5 days or so.
Has anyone else had this problem?
Brand new car and i need a new cat already?? WTF??
Kinda disappointing when u are all excited about your new car and this happens. I mean I know its not major or anything, but still.

 

**** happens, be glad it was nothing major

 

told ya
well atleast its not a big deal, some others have had cat probs aswell, yer not the only one.

 

i wonder if its gonna be a recall?
anyways, yeah it could always be worse.

 

Depends on if it's a safety hazard or not. Most only do recalls if it can pose a problem with safety. Doesn't really matter, I think those are warranted for 8 years or something like that...

 

Cool, I picked mine up on Thursday also. but just an LT. 600miles and no problems yet.

I had my Cat replaced after 30,000 km, there a few bad ones out there. they gave you a rental right?

I had one for a week when they replaced my cat

 

Yeah my oil has been at zero percent for a long time and causes my check engine light to turn on for about 24 hours once in a while.

 

Im just waiting for the part to come in and then they will call me. as for now i am driving my car. They said that it wont take long to change and to wait there.
They said about 5 days for the part to come in.

 

they said it was ok to drive?
they wouldn't let me drive mine, said that the didn't want it to clog and blow my motor

 

Does anyone know what's exactly causing the cats to clog?

 

either manufacture defect or the car is running to rich.

those are only things I could think of

 

The car is running rich probably. Seems to be a problem.

 

Well tonight as i was driving, all of a sudden it sounded like i drove over a hanger and was dragging it. i heard this awful clanging noise. I guess either my baffel in the muffler is broke or the beads from my cat are in my muffler. thats what my moms bf said cuz hes a mechanic and figured that was what it was from what i told him.
nice eh. they better get that new cat for me real soon.
so now it sounds all nasty and rattely when i drive

 

Sounds like you need new muffler bearings.
J/k lol...

 

Better take in back into the dealer tomorrow. I wouldn't drive it anymore like that!

 

Mine needed a new cat after 2 weeks and it was boosting at 17 until it came in. It ran like **** but I had to granny it around and deal for a week because its all I got to drive.

 

Well I just got home from the dealer and they said the noise was the inside of the cat, the honeycomb, basically blew up into little pieces and they are in my muffler.
They have to replace the exhaust now so my car is gonna be there for a few days cuz they are still waiting for the cat to come it. Meanwhile I have a rental car.
Hopefully this is the end of it all and no more problems.

 

I was surprised that they let you drive in the first place knowing you had a bad cat.
damage could have been much worse, glad it wasn't tho, engoy the rental, what did you get Malibu?

 

They gave me an Impala. Its new but not the nice model. More like the old mans model, with wood on the dashboard haha.
Oh well its wheels for the meantime. Can't wait to get her back though.

 

i just picked up my SS last thursday bought it new and im having the same problem i dropped it off today. They also gave me an impala as a rental. They didnt say how long they were going to have it for. Someone said many people have had this problem. have these people had there cats replaced more than once, or was it all set after they changed it the first time?

 

well the dealership told me it takes 5 days for the new cat to come in cuz its such a new part so it takes a bit. they ordered it on monday, so hopefully it comes in tomorrow, or monday the latest.
did your cat blow up into your muffler like mine? or was it just the yellow engine light sayin you need a new cat?

 

im hoping this is the first and last time. ill let ya know haha

 

The wifes 2.4 HHR had the same issue. First they tried the sensor, then the computer, then the cat. It has been fine ever since. 6 months now

 

I didn't get a light, I noticed that I was building more boost then I should have, and a whistleing noise and the engine started boosting.
and the night before my appointment my car went in to limp mode.

my Cat was clogging, even more dangerous, cause it could have caused severe engine damage. be happy yours fell apart inside.
