Warranty & Your Rights (U.S.)

Installing an aftermarket accessory does not automatically void your entire vehicle warranty. A manufacturer may deny a claim only if the part or its installation caused the problem being claimed.

Your Rights in Plain English

  • ✓No automatic void. Aftermarket parts or accessories don’t void your vehicle warranty across the board.
  • ✓Burden of proof. A dealer/manufacturer must show that the accessory or its installation caused the issue to deny that specific repair.
  • ✓No “you must use our brand.” So-called “tie-in” requirements (e.g., “you must use OEM parts to keep your warranty”) are generally prohibited unless the required item is provided free or a waiver is granted.

What the Law Says (Magnuson-Moss Warranty Act)

The Magnuson-Moss Warranty Act governs consumer product warranties in the U.S. In the context of vehicles and accessories, here are the essentials:

  • ✓No tie-in sales. A warrantor generally can’t require a specific branded part or service to keep coverage, unless it’s provided at no charge or the FTC approves an exception.
  • ✓Claim-by-claim decisions. Warranty coverage can be denied for a specific failure if the aftermarket part or its installation caused that failure—not for unrelated issues.
  • ✓Transparency. If a dealer claims your warranty is void due to an accessory, you can ask for that determination in writing, including the technical reason and evidence.

FAQ

Does adding an accessory void my warranty?

No. A warranty may only be limited for issues caused by the accessory or its installation, not unrelated issues.

Can a dealer require OEM parts to keep my warranty?

Generally no. “Tie-in” requirements are prohibited unless the required item is provided free or a waiver is granted.

What if the accessory caused the failure?

Then the dealer can deny coverage for that repair. Unrelated components should still be covered per your warranty terms.
