Lorraine--did the OnStar rep run a vehicle status report on your
Colorado? When this happened to me, they did run a report and found
nothing. This is just a mystery but mine reset and it hasn't happened
again.
What was the resolution to this? I got the message yesterday in my new
Cadillac and the red LED light next to the OnStar button. Today, the
system was working fine and the red light is off. Not sure WTF is going
on...???
