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

Mack will notify owners, and dealers will replace the alternator cable, free of charge. The recall began on June 16, 2017. Owners may contact Mack customer service at 1-800-866-1177. Mack's number for this recall is SC0407.
