Sometimes when you go out to start the vehicle, it will not start. Have been told that they have a problem with the anti-theft system on these vehicles, I can believe this since the security light does not flash when the problem occurs.

Someone should make gm own up to this problem and get it fixed, as I am sure it is not just on my vehicle.
