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.
Risk: If the turbocharger oil supply line oil leaks in the proximity of the engine exhaust manifold there would be an increased risk of a fire.
Fix: 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.
