Magnuson-Moss $50,000 Amount in Controversy for Federal Court

To sue under the Magnuson-Moss Warranty Act in federal court, your case must involve at least $50,000 in controversy, calculated across all claims in the lawsuit and excluding interest and costs.¹ The figure is a jurisdictional gate, not a damages cap. Falling short doesn’t kill the claim. It just means the case belongs in state court, where the same federal warranty protections still apply.

What Counts Toward the $50,000

The statute phrases the requirement broadly: the amount in controversy must equal or exceed $50,000 “computed on the basis of all claims to be determined in this suit.”¹ That “all claims” language matters. A single plaintiff can stack every warranty-related cause of action in the case — breach of express warranty, breach of implied warranty, violation of a service contract — and combine their values to reach the minimum. You aren’t limited to one theory of recovery when calculating the total.

For most consumers, the core of the calculation is the economic loss from the defective product. With vehicles, that usually means the difference between what you paid and whatever value you actually received before the defect emerged. The Act defines “refund” as the actual purchase price less reasonable depreciation based on actual use, and courts often apply a similar logic when measuring the controversy’s value.¹ For a car, that depreciation often hinges on mileage at the time of the first repair attempt divided by the vehicle’s expected useful life. A $55,000 SUV driven 30,000 miles before the transmission fails will have a substantially lower claim value than one that broke down at 3,000 miles.

On top of that depreciation-adjusted loss, direct out-of-pocket expenses tied to the warranty failure count toward the total. Towing fees, rental cars while a vehicle sat in the shop, storage costs, and the bills from failed repair attempts all contribute. Document every receipt. A federal judge evaluating jurisdiction will want to see that each dollar claimed reflects an actual expenditure, not a guess.

Consumers with high-value purchases or extensive consequential damages have the easiest path to $50,000. Those with mid-range products often find the math uncomfortably tight.

What Does Not Count

The statute explicitly carves out “interests and costs” from the jurisdictional calculation.¹ That exclusion has real teeth. Interest that has accrued on the purchase loan or on the claim itself cannot be added to the total. Court filing fees and service-of-process costs are out, too.

Attorney’s fees are the exclusion that stings most consumers. The Act specifically allows a prevailing plaintiff to recover attorney’s fees after winning, but those fees are treated as “costs” for jurisdictional purposes and cannot be used to inflate the claim value to cross the $50,000 line.¹ A consumer whose core loss is $35,000 can’t tack on $20,000 in anticipated legal bills to manufacture federal jurisdiction. The calculation must rest on the product-related loss and direct consequential damages alone.

Whether punitive damages count is less clear-cut. The statute excludes only “interests and costs,” not punitive damages by name. But most warranty disputes sound in contract rather than tort, and punitive damages are rarely available for a simple breach of warranty. In the handful of states where warranty claims can support a punitive award, those damages may contribute to the total, but counting on them to bridge a jurisdictional gap is risky because a court could conclude they are speculative at the pleading stage.

If You Fall Short, State Court Hears the Same Claim

The FTC itself acknowledges that “most Magnuson-Moss lawsuits are brought in state court” because of the stringent federal jurisdictional requirements.² State courts can hear warranty claims regardless of the dollar amount. There is no minimum threshold. A consumer with a $5,000 dishwasher dispute gets the same federal warranty protections in state court as someone with a $60,000 vehicle claim in federal court.

The Act specifically authorizes suit “in any court of competent jurisdiction in any State or the District of Columbia.”¹ The governing law stays the same. Available remedies stay the same. A consumer who wins can still get a replacement product or a full refund of the purchase price, minus a reasonable offset for the use they got out of the product before it failed.² The only real difference is the courthouse.

Filing fees are typically lower in state court, procedures are more streamlined, and the case usually reaches resolution faster than in federal court. Some states even allow warranty claims in small claims court for lower-value disputes, though dollar limits and procedural rules vary by jurisdiction.

Class Actions Have a Different Math

Filing a Magnuson-Moss class action in federal court requires clearing three hurdles simultaneously. Each individual plaintiff’s claim must be worth at least $25. The total amount in controversy for all claims in the suit must reach $50,000. And the complaint must name at least 100 individual plaintiffs at the time of filing.¹ Miss any one of these, and federal court won’t hear the class claim.

The 100-plaintiff requirement is dramatically higher than what typical class actions need under the Federal Rules of Civil Procedure. Most class actions require only a handful of named representatives who stand in for thousands of unnamed members. Under the Magnuson-Moss Act, all 100 must be specifically identified in the complaint. Assembling that many named plaintiffs before filing takes serious organizational effort and expense, which is one reason relatively few warranty class actions land in federal court under this statute.

Plaintiffs’ lawyers have tried to sidestep the 100-plaintiff rule by invoking the Class Action Fairness Act, which provides an alternative path to federal jurisdiction for large class actions with more than $5 million in controversy. The Ninth Circuit shut this down, holding that CAFA does not override the Magnuson-Moss Act’s specific named-plaintiff requirement.¹ Most courts that have addressed the question have agreed.

Diversity Jurisdiction Is Not a Shortcut

A consumer who can’t clear the $50,000 Magnuson-Moss threshold might wonder whether diversity jurisdiction, the rule that allows federal courts to hear disputes between citizens of different states, offers an alternative route. It doesn’t help. Diversity jurisdiction under 28 U.S.C. § 1332 requires the amount in controversy to exceed $75,000, which is an even higher bar than the Magnuson-Moss Act’s own threshold.³ A claim too small for Magnuson-Moss federal jurisdiction is almost certainly too small for diversity jurisdiction as well.

Where diversity jurisdiction does matter is for claims that exceed $75,000. A consumer with a large enough dispute and diverse citizenship from the manufacturer could bring warranty claims in federal court under § 1332 even without relying on the Magnuson-Moss Act’s own jurisdictional provision. In practice, though, this mostly affects high-value product disputes like luxury vehicles or major equipment purchases.

Winning in State Court Still Pays Your Lawyer

Attorney’s fees can’t be used to reach the $50,000 threshold, but a consumer who prevails on a Magnuson-Moss claim can recover “the aggregate amount of cost and expenses (including attorneys’ fees based on actual time expended)” that the court finds were reasonably incurred.¹ This fee-shifting provision applies in both state and federal court.

The practical effect changes the calculus for smaller claims. A consumer with a $30,000 warranty claim who files in state court and wins can recover not only the value of the defective product but also the cost of the lawyer who fought the case. That makes it economically viable for attorneys to take warranty cases on contingency or hourly terms even when the underlying damages alone might not justify the litigation expense. The fee award is discretionary, and a court can deny it if circumstances make the award inappropriate, but in the vast majority of cases where the consumer wins, fees follow.
