The defect
Mack Trucks, Inc. (Mack) is recalling certain model year 2013 and 2015 Titan (TD), model year 2014 and 2015 Pinnacle (CHU), and model years 2009-2010, 2012, and 2014-2016 Granite (GU) trucks. The chassis harness and air lines may not be properly clipped to the crossmember, which can allow the cables and air lines to fall and get twisted in the driveline.
The risk
If the electrical cables and air lines were to fall and get tangled in the driveline, it could affect the electrical system and braking system, increasing the risk of a vehicle crash.
