You already having problems with your new car? 
Remember keep it factory stock otherwise you will have tons of problems and are asking for it. Lots of times it isn't the car that's bad but the people who perform the type of quality of work on them or lack of quality work.

There is somebody else here on the forum that is having the same problem with the Check Engine light as well as one of his speakers and a few other things too with only 10 miles on the Corvette. 
With all of these electronics and computers things have gotten more complicated and $$$ Xpensive to fix..i.e. a C-6 of today to a C-3 68 to 72 Corvettes. You would think that this is a new car there shouldn't be any problems this soon..on a 30 year old classic I can understand but the 68-72 Corvettes are easier to get fixed especially the bare engine block Corvettes with just a clean engine no wires or anything blocking access to filters, engine, etc. compared to C-5/C-6 clutter under the hood. I would think that when something does go wrong between C-3's and C-5/6's and most likely something will go wrong on the classic 68 to 72 right?

My C6's Check Engine light turned on shortly after I left the dealership (see thread under C6/General). 
The button-pushing sequence I do on my C5 to get error codes in the DIC doesn't work on the C6.
Thanks for the OnStar suggestion -- I haven't used it yet (and seeing that it's the old analog system I was beginning to think it was a royal waste of money... so much for integrating with my Verizon cell service).
The local dealership has scheduled a Tues. appt for me to check this problem, plus that the cruise control won't engage. They said that unless the engine was running rough, driving with the check engine light on shouldn't cause any problems.

My point here is, just because GM doesn't come out and tell you about it doesn't mean it can't be done. I don't see why the C6 would be any different than the C4 or the C5 in that there is some sort of way to access error codes from the ECM. So stay tuned...

Nomad, you're probably right (I certainly hope so) but I recall C4 C5 Specialist posting something awhile back regarding this. He said the C6 uses the new GM communications data buss and that pulling codes without the Tech 2 would not be possible.

Any dealer who sells Corvettes should have a trained tech, and proper software, and the car is still basic OBD II. Talk to the service manager, not some salesman.
If he can't give you proper confidence that they can handle the job call GM Customer Service and order them to find you a dealer who can troubleshoot and repair your car. Also, ask them why a dealer who sells you a car cannot service it.
You've got a warranty. USE IT!

O.K. gents, if the light is on but the car runs fine, it is most likely something that was stored from a small but repeat early learning problem.
If you wish to try to reset, disconnect the battery cable on the car. Let it set for a few minutes. Reconnect the battery. You will need to reset information set up in the DIC.
Now, simply start the car and try again. If the check engine light resets there is a problem that the dealer service center will have to diagnose.
Sometimes when brand new and learning, this can happen. A complete reset such as this will end the problem.
Good luck!!
