Im looking for everyone that has had problems with their cats. Im going to fit this crap with GM. I also need to know the people that have had their warranties voided because of their cats. Please just give your screen names and your mods that you had on the car when you had problems. You can also list the dealership and what they said to you when you went to them. Thank you for your help, Im hoping that we can get something done with this.

 

Stage 2. Cat is doing great.

 

I've had mine replaced under warranty, with my current mods. Gateway Chev. in Brampton, Ontario, Canada.

car runs better now then when I first picked it up.

 

I havent had any issues with mine yet, but i ran my car on etest and my NOX are reading super high. My cats on its way out, but headers and down pipe are looking better everyday.. @fter the driveshafts.. lol

 

19,400kms on mine and it's fine so far but my car is stock. Are only people with certain Mods going bad? I am doing the HP Tuner and Intense kit soon so am i going to run into an issue?

 

How do you know your cat is bad?

 

it isn't the mods, someone almost stock had to replace his.
here's a link to when I had mine replaced.

Cat. Problems

 

mine went bad. just took it in and the replaced it under warrenty

 

Thanks for the input guys. Keep it coming,I need as much as I can get.

 

Cat went bad at like 10,000 miles. Took it in to Holiday Chevrolet in Farmington, they insistetd it was fine, re-flashed the ECU and gave it back to me. I took it maybe 15 miles from the dealership and BAM a HUGE blast of white smoke came flying out of the exhaust. "Well, there went whatever remained of my cat" i said. Ripped back to the dealer, threw my keys at the service manager and picked my loaner back up. Got a call 2 days later saying that since the cat was completely empty that it MUST'VE been hollowed out by me for performance, and they were going to have to make me pay for it.

I blew up at this and yelled at every manager I could find that day. I told them hollowing your cat is ridiculous in the first place, and why would I do it, then bring it in and tell them about it? They insisted it's IMPOSSIBLE for a car to empty its' whole cat by itself, that it just can't happen. Since the 2nd O2 sensor also went bad at the same time I asked them if couldn't it had been from the honeycomb flying out the back of my exhaust? Nah, they said. Finally after 2 more days of arguing, me refusing to pay for the repairs, 3 calls to GM. They spoke to a GM engineer who said it was possible and these cars had been known to do it. Fixed under warranty. My car is BONE stock BTW. Last time I ever went back to that dealer.

 

There you have it all anyone needs to know from now on

 

unusually high boost levels

 

there is a horror story. i would have done exactly what you did.

 

27,000 miles and my cat is still good as can be .

Also , your warranty cannot be voided because of your cat . If you physically altered the emissions in some way , there would be issues with that specific part of your warranty ....but certainly not for just a cat going bad and your entire warranty canot be voided . There are service bulitens for the converters on these cars on all models . A friend of mine is a Saturn tech and has done several on the 2.2 Ions's . You guys that are having problems with your shady dealers need to be reporting them to GM as opposed to going on the offesive with GM itself . Car manufacturers are bound to healty emissions system even past your normal warranty period .

 

I have a problem with my cat, and the problem is that its still on the car!

Soon I will rid myself of its evils.....

 

27,000 miles, no problem with cat yet.

 

stock............ in the shop for cat clogged as we speak
and my was also completly stripped out

 

nitrous destroyed my cat. i just gutted it, threw a code for the second o2 sensor, but thew car runs good now, just a little rich.
