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.
Consequence: 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.
Remedy: Mack will notify owners, and dealers will inspect the vehicles and properly clip the harness and air lines, free of charge. The recall began on September 30, 2015. Owners may contact Mack customer service at 1-800-528-6586. Mack's number for this recall is SC0393.
Do not drive: No. Park outside: No.
