New Colorado, 1 week old, 650 miles. Went to start it up and it was dead. Key turned but nothing. I turned the wheel and shifted from park to drive to park and restarted. It started up but Stabilitrak light, TCS and engine light all came on and truck drove in limp mode. (Oddly transmission clunked when I shifted to drive). Shut it off. Restarted and it ran fine but engine light was still on. Parked it until Monday. Restarted Monday and drove (now in limp mode) to the dealer. Truck is throwing lots of codes which explains limp mode but they can't find anything wrong with it or why all the codes came on. I'm wondering if parking with the wheels turned and head in against the curb explained the ignition problem which somehow tripped all these codes? Does that make any sense?
