What owners wrote
I was driving 30 mph when the car went into neutral and rolled to a stop. When I put on the brakes the engine shut off and it went into park. It would not restart or shift out of park . I was stuck in an active busy road. The car was towed to the dealer. They said it was a problem with the BCM. GMC had put out a bullletin which was to reprogram the BCM. My concern is that if this had happened on a busy interstate in traffic at highway speeds the results could have been fatal.

The vehicle was taken to the dealer, where a test drive was performed and the failure recurred. The vehicle was towed back to the dealer, where it was diagnosed with internal engine failure and determined that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure.
