■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 deny 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 in stalled incorrectly and caused damage to another part of
the vehicle otherwise covered under warran ty. 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 warranty or deny warranty coverage if the manufacturer provides the article or
service to consumers free of charge unde r the warranty or the manufacturer has
secured a waiver from the Federal Trade Commission.
