The Base Engine Warranty covers any failures of the Engine which result, under normal use and service, from a defect in material or factory workmanship(Warrantable Failure). This coverage begins with the sale of the Engine by Cummins and continues for five years or 100,000 miles (160,935 kilometers), whichever occurs first, from the date of delivery of the Engine to the first user.

Engine aftertreatment components included in the Cummins Critical Parts List (CPL) and marked with a Cummins part number are covered under Base Engine Warranty.
