2006 coupe won't start. There is a light on the dash, of a car with a pad lock. Everything works windows, doors, hatch release etc. I read it might be the battery so I bought a new one. Same thing. When I hit the start button everything goes dark then reboots to the beginning. "Corvette by Chevrolet" I believe. It is an automatic and I know my brake safety works because if I don't depress it the dic tells me to press brake pad.
