Cummins has introduced a new three-year/unlimited mile base warranty for the B6.7 engine. This applies to 2017 B6.7 engines in on-highway trucks in North America. The base warranty includes the same comprehensive coverage for parts and labor on warrantable failures for the engine and after treatment system. In addition, towing or travel coverage has been expanded from one to three years. There’s no deductible, and consumables used in the repair are included.
