Mack Trucks, Inc.
The problem
Mack Trucks, Inc. (Mack) is recalling certain 2019 Mack Granite (GU) vehicles equipped with snow plow lamp preparation kits. The snow plow headlights can be turned on without other exterior lights, and high beam indicator will not work when the snow plow high beams are on. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."
Risk
The driver may operate the vehicle with the snow plow headlights on but the marker and tail lamps off, reducing the vehicle's visibility and increasing the risk of a crash.
What owners should do
Mack will notify owners, and dealers will update the software related to the plow lights, free of charge. The recall began December 19, 2018. Owners may contact Mack customer service at 1-800-866-1177. Mack's number for this recall is SC0414.
