Illegal to Deny Warranty Based on Aftermarket Part Use, Says FTC

SEMA recently reported an FTC alert regarding the Magnuson-Moss Warranty Act. The FTC consumer alert draws into light the stipulation that it is illegal for vehicle manufacturers to deny a warranty based on a consumer’s use of aftermarket parts. In other words, if you use aftermarket parts on your vehicle and problems occur, your vehicle manufacturer must stand by the warranty.

The FTC alert highlighted key parts of the law, specifically noting protections for car owners.

The FTC also notes that the phrase “aftermarket part” refers to any part made by a company other than the vehicle manufacturer. According to the Magnuson-Moss Warranty Act, there can be no specifications on brands of parts, services, or vehicle modifications. The only exception is when those parts or services were given for free.
