NHTSA Campaign 13E073000

ELECTRICAL SYSTEM:SOFTWARE

Issued by General Motors LLC · Reported Dec 20, 2013 · 18 vehicles affected

What's wrong

General Motors LLC (GM) is recalling certain software intended for 2015 vehicles that was installed by service centers into model year 2014 Chevrolet Silverados and GMC Sierras equipped with Allison A1000 transmissions. The incorrect software may cause the transmission indicator not to display that gear position "1" has been selected. As such, this vehicle does not conform to Federal Motor Vehicle Safety Standard (FMVSS) number 102, "Transmission Shift Lever Sequence, Starter Interlock, and Transmission Braking Effect."

Consequence

The transmission position indicator may not show that the transmission is in first gear (1) and not drive (D). If the drivers pulls into traffic, the vehicle's speed would be limited, resulting in an increased risk of a crash.

Remedy

GM will notify owners, and dealers will upload the correct transmission software, free of charge. The recall began on January 27, 2014. Owners may contact Chevrolet at 1-800-222-1020 and GMC at 1-800-462-8782. General Motors' number for this recall is 13442.
