The called later on Tuesday, said they found a loose battery cable. Odd, since I've never done anything under the hood outside of removing a few leaves. They charged the battery and said everything was cool. Here's the interesting part, they said GM wants them to keep the truck overnight, drive it home and see if it occurs again. They ended up calling on Friday to say it was ready to be picked up. The problem is that it doesn't occur daily, so for them to keep it doesn't really serve a purpose. I don't think it's fixed, because it's happened 4 times and they haven't found anything. Charging the battery is not a fix, but just a means to get the truck running again. I definitely think it will happen again. I'm going to write a letter to GM, so they are on notice about the situation.
Here's what I found online regarding the lemon law for NY:
If your car does not conform to the terms of the written warranty and the manufacturer or its authorized dealer is unable to repair the car after a reasonable number of attempts during the first 18,000 miles or two years, whichever comes first, you may be entitled to a full refund or a comparable replacement car.
It is presumed that there has been a reasonable number of attempts to repair a problem if, during the first 18,000 miles of operation or two years from the original delivery date, whichever comes first, either (a) the manufacturer (or its authorized dealer) has had an opportunity to repair the same problem four or more times and the problem continued to exist at the end of the fourth repair attempt; or (b) the car was out of service by reason of repair for a cumulative total of 30 or more calendar days for one or more problems.
Should it come to this, I'm guessing it's a good idea to retain an attorney. I'm guessing GM/Dealer will be reluctant to give me a refund or replacement.
