What’s wrong with it?
Low turn signal visibility may not alert other drivers to a turning vehicle, increasing the risk of a crash.
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.”
