Oh, you've seen them before: those little stickers or tags making clear that if you want your warranty on a product to remain valid, you'd better leave one or more of its parts untouched. The idea, of course, is that consumers are barred from using third-party parts and repair services for the product if they would like to hang on to that guarantee.

Well, as you've probably long suspected — or desperately wished, at least — those warnings are bunk. Worse than that, actually: The Federal Trade Commission says they're illegal.

"Provisions that tie warranty coverage to the use of particular products or services harm both consumers who pay more for them as well as the small businesses who offer competing products and services," Thomas B. Pahl, acting director of the FTC's Bureau of Consumer Protection, said in a statement released Tuesday.

Specifically, the agency explained, those provisions violate the 1975 Magnuson-Moss Warranty Act, which bars companies from conditioning their warranties on demands that consumers use certain articles or services in connection with the original product.

That hasn't stopped companies from doing it anyway — and now, the FTC is fed up.

The agency said it had "sent warning letters to six major companies that market and sell automobiles, cellular devices, and video gaming systems in the United States." The FTC's announcement did not identify the companies by name.

But, as Ars Technica points out, the sample language listed in the FTC statement matches the terms found on several companies' websites. And the media outlet felt no compunction naming names:

  • " Hyundai's warranty states that 'the use of Hyundai Genuine Parts is required to keep your Hyundai manufacturer's warranties and any extended warranties intact.'
  • " Nintendo's warranty states that 'this warranty shall not apply if this product is used with products not sold or licensed by Nintendo.'
  • " Sony's warranty states that 'this warranty does not apply if this product ... has had the warranty seal on the PS4™ system altered, defaced, and removed.' "

(You'll note that since Ars Technica published its post, it appears Hyundai has changed its language to "the use of Hyundai Genuine Parts is strongly recommended.")
Whoever it was the FTC contacted, at any rate, the agency has given them 30 days to correct any potential violations on their websites. If at the end of the month those violations persist, they "may result in law enforcement action."
