2015–2023 Mack Granite (gr), Mack Granite (gu): Exterior Lighting recall

NHTSA campaign 23V600000 · 27K units potentially affected · filed Aug 25, 2023

What's wrong

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."

Why it matters

Low turn signal visibility may not alert other drivers to a turning vehicle, increasing the risk of a crash.

The 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.

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.
