So, I'm driving home from work today listening to a CD and up ahead I see a couple of police cars have a late model midsize pickup pulled over. Suddenly as I get closer my CD stops playing, my average mileage display goes to -- --, the a/c compressor shuts off but not the fan and then the whole DIC display goes blank. A second or 2 later it comes back on for a couple of seconds and goes back out, comes back on and goes out again. As I go past the the 2 police cars on either side of this pickup, my display starts showing "Theftlockout" but the car keeps running fine. I pull on into the grocery store parking lot up the road, park, and shut off the car. When I restart everything is fine and I've had no repeats. I bet the cop cars swepted the pickup via Onstar to shut it down and mine picked up the signal as I went by. Anybody else ever experienced this?
