A Mack Trucks turn-signal problem affects 27,418 vehicles, a federal recall report says.
The issue involves certain Granite GR and GU models from 2015 to 2023. The signal doesn’t meet revised lighting visibility standards, the report said.
“The turn signals may be positioned incorrectly, reducing their visibility,” the National Highway Traffic Safety Administration said in an Aug. 29 letter. “As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, ‘Lamps, Reflective Devices, and Associated Equipment.’”
In February 2022, the NHTSA issued a final rule regulating newer vehicles’ adaptive driving beam technology. That led Mack’s Product Safety Working Group to determine potential non-compliance could occur because of some chassis extensions and hood variations, the recall report said.
Dealers will add more turn signal lighting to remedy the matter free of charge, recall documents said.
Notices went out to dealers beginning Sept. 1, and owners of the affected vehicles will be notified by Oct. 17.
