  POWER TRAIN:TRANSFER CASE (4-WHEEL DRIVE)

  General Motors LLC (GM) is recalling certain model year 2014-2015 Chevrolet Silverado and GMC Sierra vehicles, and model year 2015 GMC Yukon and Chevrolet Suburban and Tahoe vehicles. In the affected vehicles, an electrical signal short may cause the transfer case to shift to neutral without the driver's input.

  Risk: If the transfer case switches to neutral while the vehicle is parked and the parking brake is not in use, the vehicle may roll away increasing the risk of injury to bystanders. If the transfer case switches to neutral while the vehicle is being driven, the vehicle would lose drive power, increasing the risk of a crash.

  Remedy: GM will notify owners, and dealers will re-program the software in the transfer case control module, free of charge. The recall began in early August 2014. Owners may contact General Motors customer service at 1-800-222-1020 (Chevrolet), or 1-800-462-8782 (GMC). GM's number for this recall is 14192.
