Signed into Law
Magnuson-Moss Warranty Act
Summary
The foundational federal warranty law (1975). Bars manufacturers from conditioning a written warranty on the use of branded parts or authorized service (anti-tying), and from voiding a warranty merely because a consumer used aftermarket parts or an independent repairer — unless the manufacturer proves that part or service caused the defect. Enforced by the FTC. It does NOT require manufacturers to provide parts, tools, or repair documentation.
