i am an auto mechanic by trade, this is no the first time i have run in to these kind of problem with gm cars, most of the time it has to do with the alarm system. This is bull i don't see why they cant make these problems easier to fix and give you ways to get information.

The car only does this during the summer months. I have 2 young children and we end up getting stranded in a hot car that won't start. I have put a new ignition in it, had the electrical gone through and the steering column. The cost of the unfixable problem has now surpassed what the car is worth.
