As long as the security light flashes the truck will not start. I take off the negative clamp off the battery an wait 10 minutes it will start. If I use the remote to lock the truck every third time the truck will not start. An some times it does it more than that. So I don't use the remote. Stationary. This happens several times a week.

I have a 12 month old chevy colorado, bought new. For 9 months, no issues. Then in october, it simply won't start. Dead battery. I drove it regularly to and from work each day, so it's not from non-use. I took it to service and they said it was a bad battery. They replaced it. About a month later, same thing. Dead battery and car won't start, but lights work, radio works. I take it in again, and they can't find a reason. They keep it a week (static) and say there is nothing wrong. But it works when I leave the service department. Three weeks later, same thing. Car won't start and I'm tired of getting stranded. And I drive it regularly. They take it to another dealers service and they run tests but can't find anything wrong. They call chevy who gives them direction, but chevy doesn't let on that there's a problem. But I go online and find many issues with the same vehicle. Since this is the 3rd attempt to fix it, I'm going to pursue the lemon law.
