17V261000Electrical SystemApril 18, 2017 · 3,282 units

Defect

Mack Trucks, Inc. (Mack) is recalling certain 2015-2018 LR and 2011-2018 TerraPro (LEU and MRU) trucks. The alternator cable may be insufficiently thick to handle the current, and, as a result, may overheat.

Consequence

If the alternator cable overheats, it would increase the risk of a fire.

Remedy

16V099000TransmissionFebruary 19, 2016 · 33,981 units

Defect

Mack Trucks, Inc. (Mack) is recalling certain model year 2012-2016 Granite (GU), Pinnacle (CHU, CXU), TerraPro (LEU, MRU), Titan (TD), and LR trucks manufactured from September 1, 2011, through September 8, 2015. The cap nut that retains the interaxle driveshaft yoke to the rear axle input shaft may loosen.

Consequence

If he cap nut loosens and falls off, the yoke can separate from the axle input shaft and allow the drive shaft to disconnect, increasing the risk of a crash.

Remedy

Mack will notify owners, and dealers will replace the cap nut. The input shaft threads will be inspected for damage. Any damaged input shaft will be replaced. These repairs will be performed free of charge. An interim notice was sent to owners on April 25, 2016. The recall began on June 7, 2016. Owners may contact Mack customer service at 1-610-709-2131.

15V702000EngineOctober 26, 2015 · 2,571 units

Defect

Mack Trucks, Inc. (Mack) is recalling certain model year 2010-2016 Granite (GU), LR, and TerraPro (LEU, MRU) trucks manufactured November 17, 2009 to October17, 2015. The affected trucks have engines with a turbocharger oil supply line that may contact or interfere with the turbocharger inlet elbow, clean air intake clamp, or the air fuel control tube, and result in an oil leak.

Consequence

Remedy

Cummins will notify owners on behalf of Mack, and dealers will inspect for oil supply line interference or damage, eliminating the interference and replacing the oil supply line, as necessary, free of charge. The recall is expected to begin November 30, 2015. Owners may contact Cummins at 1-800-343-7357 or Mack customer service at 1-800-866-1177. Cummins' number for this recall is SC0396.
