Warranty coverage varies by manufacturer. A new Generac generator comes with a 5-year limited warranty. This includes parts and labor for the first 3 years. In the 4th year, only parts are covered, and in the 5th year only major components (motor, stator) are covered. Customers have the option of purchasing extended warranties from licensed dealers; however, these usually must be purchased within the first year of ownership. Briggs and Stratton DX models, only available for purchase from authorized dealers, come with a 10-year factory warranty that includes parts and labor for the whole term.
