Why Congress Passed This Law

Before 1975, written warranties were often dense legal documents designed more to limit seller liability than to help buyers. A product could be sold with a warranty that sounded protective but contained so many exclusions that it was nearly meaningless in practice. Consumers rarely saw warranty terms before purchasing, and there was no standardized language to make comparisons possible.

The Magnuson-Moss Warranty Act addressed these problems by requiring warrantors to disclose warranty terms clearly and conspicuously, and to make those terms available before the sale — not buried in packaging the buyer can't open until they get home. The law also directed the FTC to create rules implementing these requirements, which it did through the FTC Warranty Rules still in effect today.

Magnuson-Moss and Extended Service Contracts

Extended warranties — more accurately called service contracts — are regulated by Magnuson-Moss only in limited ways. They must not be deceptively labeled as warranties if they are actually service contracts, and certain disclosure requirements apply. However, the core protections around full vs. limited warranties are directed at manufacturer and seller written warranties, not third-party service agreements. See when extended warranties make sense for a fuller picture.

What the Law Actually Requires

Magnuson-Moss imposes obligations on sellers and warrantors in several specific areas:

  • Pre-sale availability: Written warranties on products priced above $15 must be made available to buyers before purchase — in-store displays, on request, or posted online for e-commerce.
  • Clear labeling: Every written warranty must be designated as either full or limited. These are legal terms with defined meanings, not marketing language.
  • Full warranty standards: A full warranty must cover defects within a reasonable time at no charge, cannot require the consumer to do anything unreasonable to get coverage, and must offer a refund or replacement if the product can't be fixed after a reasonable number of attempts.
  • No tying allowed: Warrantors cannot require consumers to use specific brands of parts, accessories, or repair services as a condition of the warranty — unless those items are provided free of charge.

Request Warranty Terms Before You Buy

Federal rules entitle you to review warranty terms before completing a purchase on any product priced above $15. If terms aren't posted near the product in-store, ask a sales associate — they are required to make the document available. For online purchases, the warranty must be accessible on the product page before checkout.

What the Law Does Not Cover

Understanding the limits of Magnuson-Moss is just as important as knowing its protections:

  • No warranty is required: The law only regulates warranties that sellers voluntarily offer in writing. A seller can legally sell a product with no written warranty at all.
  • Services are not covered: Contracts for services — like a home repair agreement — are outside Magnuson-Moss's scope, though other consumer protection laws may apply.
  • Business purchases are excluded: The law protects consumers buying for personal or household use. Goods purchased primarily for business purposes are not covered.
  • It doesn't override poor product quality: Magnuson-Moss governs how warranties are disclosed and honored, but it doesn't guarantee a product will perform well or last a specific time.

Many consumers are also surprised to learn that warranty myths — like the idea that any third-party repair automatically voids coverage — have no basis in Magnuson-Moss law. The most costly warranty myths explained article covers these in detail.

1975

Year Magnuson-Moss Warranty Act was enacted

The law was signed by President Ford and represented the first federal statute to regulate written consumer product warranties at a national level.

$15

Minimum price threshold for pre-sale disclosure

FTC Warranty Rules require that written warranties on consumer products priced above $15 be made available to buyers before purchase.

$25

Threshold requiring single-document warranty

For products priced above $25, the FTC requires the warranty to be presented as a single document, improving readability and transparency for consumers.

Implied Warranties and the Interaction With State Law

Magnuson-Moss intersects with state law in an important way. Implied warranties — particularly the implied warranty of merchantability (the basic promise that a product will do what it's supposed to do) — arise under state law, not federal law. Magnuson-Moss does not create implied warranties, but it does limit a warrantor's ability to disclaim them.

Specifically, if a seller provides any written warranty, they cannot fully disclaim implied warranties under Magnuson-Moss. They may limit the duration of implied warranties to match the written warranty period, but they cannot eliminate them entirely. This protection is meaningful because implied warranties often provide coverage even when written warranty terms are narrow.

State consumer protection laws can go further still. State laws frequently add protections beyond the federal floor — including longer implied warranty periods and stronger remedies for deceptive practices. Always check your state's rules alongside federal rights.
