Check engine light?.

Sounds like you have an idiot service advisor.
OBDII systems turn off the CEL if you go through 3 clean start/off cycles. However, unless you clear the computer but pulling the fuse or battery, the code should still be stored. You should get the code read regardless, to try to figure out what the problem could be.

That's what I thought.

mine was just the gas cap was loose. and the other time it came on was just before the computer in my car went out.

Hmm.. well, at least I'm not the only one that had computer issues with an 06. Not that I'm wishing bad things for anyone with an 06. It's just that the service manager had never seen a P0606 before on such a new model.

My check engine light came on and my aveo won't go higher then second gear(40 mph) initally the hold light was stuck on without me pressing the hold light but turning the aveo off and then on again the hold light went out but the check engine light stayed on. Please advise for those who don't know I have a hatch and about 19200 mi on it....

Get the CEL code read... Autozones apparently do it for free.
Usually what OBDII systems do is if it detects a fault, it'll also immediately trip the "limp home" mode to limit power so more things don't get screwed. But usually that means 3rd gear on most automatics, not 2nd.
What's really weird for me after the new ECM is the mileage I'm getting. I used to get no better than 10-11 L/100 kms in the city. Right now I'm in the 8 L/100 kms range for city, which is pretty sweet... hopefully it stays that way, and that the crappy mileage I was having before was due to a bad computer to begin with.

Yeah so I brought it in to service yesterday and they hooked it up to the scanner tool and then proceeded to fry my ECM!!!......
I have a loaner until they put in a new ECM (big honkin' Impalla), I went a removed our kids car seat and found a few sheets on how to scan the computer laying on the pass. seat, it said in red lettering to "make sure your scan toon has the proper updates before you scan the computer", the other three talked about the problem with the throttle body freezeing when it goes below -15.
So obviously he or she didn't have the right software to scan the car safely and fried the ECM, but I could be wrong...
I get it back Thursday...

hahah those techs must be idiots...ive gotten mine scanned multiple times already with no problems

[y2dgone]

well at least you get a new ecm and loaner car for free!

[ClintCart]

well at least you get a new ecm and loaner car for free!

Very true.
I have it back now good as new, they washed it too.
Everyone makes mistakes, just wish I knew what happened with the old one.

[AVE0SAM]

actually it was probably defective...i believe someone else got fried too
