Suspension / Front / Hub
Defect, in the NHTSA record
Mack Trucks, Inc. (Mack) is recalling certain model year 2012, 2014-2015 and 2017 Granite (GU), 2012-2017 Pinnacle (CHU, CXU), and 2013-2015 and 2017 Titan (TD) trucks manufactured January 7, 2011, to September 29, 2016.

Defect, in the NHTSA record
Mack Trucks, Inc. (Mack) is recalling certain model year 2014-2015 CXU trucks manufactured June 1, 2013, to November 28, 2014. These trucks may be equipped with an 88 liter air reservoir for the brakes instead of a 96 liter air reservoir.

Parking Brake / Driveline / Hydraulic / Actuator
Defect, in the NHTSA record
