Our warranty philosophy

Cummins’ guiding principle when it comes to warranties is simple: We agree to pay to fix any part that has failed due to a defect in Cummins materials or factory workmanship. 

For RV generators used in an RV application, this means you’re protected three years from the warranty start date, or 2,000 hours, whichever comes first. For RV generators used in non-RV applications, the warranty coverage period is one year from the warranty start date, or 1,000 hours, whichever comes first. Extended warranty coverage is also available for purchase and covers you for five years from the warranty start date, or 3,000 hrs, whichever comes first.
