Exterior Lighting › Turn Signal (23V600000, 2023-08-25)
Problem: Mack Trucks, Inc. (Mack) is recalling certain 2015-2023 GU and GR vehicles. The turn signals may be positioned incorrectly, reducing their visibility. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."
Risk: Low turn signal visibility may not alert other drivers to a turning vehicle, increasing the risk of a crash.
Free fix: Dealers will add additional turn signal lighting, free of charge. Owner letters were mailed September 25, 2024. Owners may contact Mack's customer service at 1-800-866-1177. Mack's number for this recall is SC0448.

Problem: Mack Trucks, Inc. (Mack Trucks) is recalling certain 2020-2021 Granite vehicles equipped with certain SL2065 steerable lift axles. The lower rear pivot cap screws may not be long enough to sufficiently engage the locking feature of the corresponding nuts.
Risk: The short screws can cause the hardware to separate from the suspension system and become a road hazard, increasing the risk of a crash or injury.
Free fix: Mack Trucks will inspect the suspension system and replace the lower rear pivot cap screws, as necessary, free of charge. Owner notification letters were mailed on July 30, 2021. Owners may contact Mack Trucks' customer service at 1-800-866-1177. Mack Trucks' number for this recall is SC0426.

Problem: Mack Trucks, Inc. (Mack) is recalling certain 2021-2022 Anthem, Granite, and Pinnacle vehicles. The hubcap compression spring can cause the hubcap to separate.
Risk: A separated hubcap can create a road hazard, increasing the risk of a crash.
Free fix: Dealers will remove the hubcap, free of charge. Owner notification letters were mailed June 30, 2021. Owners may contact Mack customer service at 1-800-866-1177. Mack's number for this recall is SC0425.
