■Statement on Warranty Coverage for Aftermarket and Recycled Parts
The Magnuson-Moss Warranty Act, 15 U.S.C. s.2301 et seq., makes it illegal for
motor vehicle manufacturers to void a motor vehicle warranty or deny warranty
coverage solely because an aftermarket or recycled part has been used to repair the
vehicle or someone other than the authorized service provider performed service on
the vehicle. This provision does not apply to a new motor vehicle purchased solely
for commercial or industrial use.
Under federal law, a manufacturer may de ny warranty coverage and charge for
repairs to a vehicle if it is discovered that an aftermarket or recycled part installed on
the vehicle is defective or was installed incorrectly and caused damage to another
part of the vehicle otherwise covered under warranty. The Federal Trade
Commission requires that a manufacturer demonstrate that an aftermarket or
recycled part or service performed by a person other than an authorized service
provider caused damage to another part of the vehicle otherwise covered under
warranty before denying warranty coverage . Additionally, federal law allows a
manufacturer to void a motor vehicle warra nty or deny warranty coverage if the
manufacturer provides the article or service to consumer s free of charge under the
warranty or the manufacturer has secured a waiver from the Federal Trade
Commission.
