Mitsubishi Electric Automotive America introduces Diamond Gard, a new warranty program that pays for parts and labor resulting from any mechanical failures to its heavy duty aftermarket starters and alternators, and covers products sold throughout North America. Diamond Gard is a no-fault, manufacturer's limited warranty. Coverage includes any Mitsubishi Electric All Makes (aftermarket program) starter or alternator sold prior to the launch date that falls within the standard Mitsubishi Electric All Makes warranty period of three years (unlimited miles) that fail under normal use and proper maintenance.
