Magnuson-Moss Warranty Act
The Magnuson-Moss Warranty Act is a federal law enacted in 1975 that governs written warranties on consumer products sold in the United States. It does not require sellers to offer a written warranty, but when one is offered, the law sets specific rules about what it must disclose and how it must be honored. The Act also restricts sellers from using a written warranty as a way to strip away implied warranty protections consumers already have under state law.
The Act is enforced by the Federal Trade Commission (FTC) and grants consumers the right to sue in federal court if a warrantor fails to comply, including the ability to recover attorneys' fees in some cases.
What the Magnuson-Moss Warranty Act Actually Does
Passed by Congress in 1975, the Magnuson-Moss Warranty Act was designed to address a simple problem: written warranties were often confusing, buried in fine print, and difficult to enforce. The law gave the Federal Trade Commission authority to set clear rules, and it gave consumers a federal legal remedy when those rules are violated.
The Act has two primary functions. First, it requires warrantors — any company or individual who offers a written warranty — to disclose warranty terms clearly and conspicuously before a sale. Second, it limits what warrantors can do to weaken consumers' existing legal protections. Sellers cannot, for example, use a written warranty to disclaim all implied warranties, which are the baseline protections built into most sales under state law. They can restrict implied warranties to the duration of the written warranty, but they cannot eliminate them entirely in most cases.
For a broader look at how written and implied protections interact, see our explainer on implied vs. express warranty rights.
The Act Covers Written Warranties Only
The Magnuson-Moss Warranty Act is triggered only when a seller provides a written warranty. If a product comes with no written warranty, the Act does not apply — though consumers may still have protections under implied warranty laws in their state. These implied protections exist independently of any document the seller provides.
Full vs. Limited Warranties: A Meaningful Distinction
One of the Act's most practical contributions is requiring warrantors to label their written warranties clearly as either full or limited. These are not marketing terms — they carry specific legal meaning.
A full warranty obligates the warrantor to repair or replace a defective product within a reasonable time, at no cost to the consumer. If the product cannot be repaired after a reasonable number of attempts, the consumer is entitled to a refund or replacement. Full warranties cannot require the consumer to return a registration card or pay any fees to activate coverage.
A limited warranty is more flexible. It may restrict coverage to parts only, require the consumer to pay labor costs, set a shorter duration, or limit remedies in other ways. Most warranties consumers encounter in everyday purchases — appliances, electronics, tools — are limited warranties. Knowing which type you have tells you immediately what to expect if something goes wrong.
1975
Year the Magnuson-Moss Warranty Act was enacted
The Act was signed into law by President Gerald Ford and remains a cornerstone of U.S. consumer protection regulation for product warranties.
$15
Minimum product price triggering full disclosure rules
Products sold for $15 or less are exempt from the Act's most detailed written warranty disclosure requirements, per FTC regulations implementing the statute.
3
Minimum products before informal dispute program required
FTC rules generally require warrantors offering warranties on multiple products to maintain an informal dispute resolution mechanism if they want it to serve as a prerequisite to litigation.
What the Act Does Not Cover
Understanding the Act's limits is just as important as understanding its protections. The law applies only to written warranties on consumer products — goods purchased primarily for personal, family, or household use. It does not apply to:
- Products purchased for business or commercial purposes
- Service contracts (these are governed separately)
- Oral warranties or informal seller promises
- Products priced at $15 or less, which face reduced disclosure requirements
- Real estate or intangible goods
The Act also does not force any seller to offer a warranty in the first place. If a product comes with no written warranty, the Act is simply not triggered — though state-level implied warranty protections may still apply.

Using Your Rights When a Warranty Claim Is Denied
When a warrantor fails to honor a written warranty, consumers have real options. The Act allows individuals to file suit in state or federal court, and in qualifying cases, prevailing consumers may recover their attorneys' fees — an important provision that makes litigation more accessible for lower-dollar disputes.
Before filing suit, many warrantors are required to offer an informal dispute resolution mechanism, such as arbitration or mediation. If the warrantor has such a program and it meets FTC standards, consumers may need to use it first. These programs are free to the consumer and can resolve disputes faster than litigation.
If you believe a warrantor is denying a legitimate claim, documenting your communications — dates, names, and what was said — strengthens any formal complaint or legal action. The FTC accepts consumer complaints and uses them to identify patterns of non-compliance, even if it does not pursue individual cases.

Keep Your Warranty Documents After Purchase
Save a copy of any written warranty, your purchase receipt, and records of all communications with the warrantor. If a claim is denied and you need to escalate — through a dispute resolution program or in court — these documents are essential evidence. Digital photos of physical paperwork are a quick and reliable backup.
