Certain (4 wheel-drive) Trailblazer and GMC Envoy vehicle. The calibration of the active transfer case control module may cause insufficient high speed gear engagement. If the gear is not engaged, the vehicle can roll when the transmission is in "park" and a crash could result without warning. Correction: dealers are to reprogram the active transfer case control module (ATCM) calibration to increase gear engagement.
