Recall 14V374000

Transfer Case Shifts To Neutral When Not Commanded

Recall Details

The transfer case may short and shift to neutral unexpectedly while either parked or being driven. Dealers will re-program the software in the transfer case control module free of charge to resolve the concern.

Our Quick Take

The transfer case may shift to neutral when not commanded, which could result in the vehicle rolling away when parked, or loss of vehicle power when being driven. This would increase risk of a crash.

What Should You Do?

Recalls on your Chevrolet or General Motors truck must be performed by a General Motors dealership. General Motors began notifying known owners of affected vehicles in August, 2014. If you did not receive a notification, but wish to check to see if your vehicle is included, please contact one of your local General Motors dealerships. They will also check for any other uncompleted recalls on your vehicle. For best results, be prepared to provide your Vehicle Identification Number (VIN) to the service department consultant you speak with. The General Motors recall number is 14192.

Summary
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.
Consequence
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.

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.
