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 sets rules about what information must appear in a warranty, prohibits certain deceptive warranty practices, and gives consumers the right to sue in federal court when warranty terms are violated. It does not require manufacturers to offer a warranty — but when they do, it must meet specific standards.
The Act is enforced primarily by the Federal Trade Commission (FTC) and applies to written warranties on tangible consumer products costing more than $15. It also restricts how sellers can condition warranty coverage on the use of specific parts or services.
What the Law Actually Does
Passed by Congress in 1975, the Magnuson-Moss Warranty Act established the first federal framework for consumer product warranties. Before it existed, warranty language was largely unregulated — manufacturers could write nearly anything, bury exclusions in fine print, and leave consumers with little recourse.
The law addresses three core problems: opaque warranty language, deceptive conditions on coverage, and limited consumer remedies. It requires that any written warranty on a consumer product must be made available before purchase (so you can read it before committing), written in clear and simple language, and labeled explicitly as either a full warranty or a limited warranty. That distinction matters — see our guide to warranty terms for a detailed breakdown of what each label means in practice.
It's also worth understanding how written warranties interact with implied warranties. If a seller offers any written warranty, they cannot completely disclaim the implied warranty of merchantability — the basic assurance that a product works as expected. For a deeper look at how these protections layer together, see how express and implied warranties differ.
The Act Covers Consumer Products, Not Business Purchases
Magnuson-Moss applies specifically to products bought for personal, family, or household use. Items purchased primarily for commercial or business purposes generally fall outside its scope. If you're buying equipment for a business, different legal frameworks — including contract law and the Uniform Commercial Code — are more likely to govern warranty disputes.
What Manufacturers Must Include — and What They Can't Do
When a written warranty is offered, the Act and FTC regulations require it to disclose specific information in plain language, including: who is covered, what products or parts are covered, what the warrantor will do when something goes wrong, how long coverage lasts, and how to obtain warranty service.
The law also limits what manufacturers can prohibit. The most important protection for modern shoppers is the restriction on tie-in sales — a company generally cannot require you to use only their branded parts, accessories, or repair services as a condition of keeping your warranty valid. This principle is increasingly relevant as consumers exercise their right to independent repair.
There are common misconceptions here. Many shoppers believe that opening a device or using a non-manufacturer repair shop automatically voids all warranty coverage. The law generally does not support that position. For more on this, warranty myths that cost shoppers money addresses the most frequent misunderstandings directly.

Core consumer enforcement options under the Act
Consumers may report violations to the FTC, contact their state attorney general, or file a private civil lawsuit — with attorneys' fees recoverable if they prevail.
How Consumers Can Enforce Their Rights
Knowing your rights matters only if you can act on them. The Magnuson-Moss Act gives consumers three main enforcement paths. First, you can report violations to the Federal Trade Commission, which has authority to investigate and penalize non-compliant warrantor practices. Second, your state attorney general may pursue action on behalf of consumers. Third — and most directly — you can file a private lawsuit in state or federal court.
The Act's provision allowing consumers to recover attorneys' fees and court costs if they prevail is significant. It lowers the practical barrier to bringing a claim over a product that may not be worth thousands of dollars on its own. Class actions are also permitted under the Act when many consumers face the same warranty violation.
If a dispute arises, start by documenting everything: keep your receipt, the warranty document, all repair communications, and records of what failed and when. Many warranty disputes are resolved through the warrantor's own informal dispute resolution process before litigation becomes necessary.
