The group's understanding is that simply reporting the symptoms should be sufficient. The dealer doesn't have to duplicate them. And you can go to any Chevy dealer - your warranty is with GM, not the dealer you bought it from.Problem is, do I need paperwork or anything to get it replaced? The dealership I purchased it from is out of state so could I take it to the local Chevy dealer?
I notice that you're reporting problems on start up. I'm inclined to think you've got a battery going out - the voltage is dropping too low during cranking and getting all the electronics messed up. How old is the battery? If original, you're due.
