No-Fault Warranty Gold (NFWG)
Where applicable is extra warranty coverage that provides a first-time free replacement unit regardless of cause of unit failure (while in normal operating situations). NFWG also allows a guarantee of labor of up to $95 per hour Mitchell time for repair or replacement. Towing, rental car, and fluid allowances are also included. No product warranty covers labor in the event the installation is DIY. If DIY elects to make their own installations or repair, they forfeit their labor portion of this warranty.
