Q: Can a Dealer Void My Warranty? The Magnuson-Moss Warranty Act Explained

Whether you have your eye on a performance exhaust system or are researching aftermarket cold air intakes—and you’re worried about voiding your vehicle’s warranty—have no fear. You need to refer to the Magnuson-Moss Warranty Act, which protects consumers from being wrongfully denied warranty coverage when they customize their rides.

Don’t automatically believe the myths that modifying your vehicle with aftermarket accessories voids your warranty. While this may be true in certain circumstances (and you should check with your vehicle’s manufacturer terms of warranty) , you shouldn’t take this as an absolute. According to the Magnuson-Moss Warranty Act: a vehicle manufacturer cannot void the warranty of your vehicle due to an aftermarket part unless they can prove that the aftermarket part was the cause of or contributed to the failure of the vehicle (15 U.S.C. 2302 (C)). This means that a vehicle's warranty cannot be "voided;" the dealer can only deny a claim if the stock part failed due to damage or unreasonable use.

Q: History of the the Magnuson-Moss Act

Passed in 1975, the Magnuson-Moss Warranty Act is a federal law that governs warranties on consumer products. Under this Act, sellers and manufacturers of consumer products must provide consumers with detailed information about warranty coverage. Sponsored by Senator Warren G. Magnuson of Washington and U.S. Representative John E. Moss of California, this Act affects both the obligations of warrantors and the rights of consumers under written warranties.

Q: Purpose of the Magnuson-Moss Act

The Act’s purpose is to help consumers understand their products’ warranties and to make these warranties enforceable. In essence, this statute was created to protect consumers from deceptive warranty practices and provide clarity regarding warranties on consumer products. To comply with the Magnuson-Moss Act, consumers should obtain complete information about warranty items and conditions and compare warranty coverage before any purchase. The Act also provides the Federal Trade Commission with a better means to protect consumers, while strengthening the incentive for companies to perform their warranty obligations in a thorough and timely manner. While all consumer products are not required to have warranties, if one is given, it must comply with the Magnuson-Moss Act.

Q: Summary

When accessorizing your vehicle with aftermarket parts, your warranty claim cannot be automatically denied, nor can your warranty be voided, if you install non-OEM parts in your vehicle. The dealer must prove the aftermarket parts caused the failure.

For example, if your windshield wiper motors fail, your vehicle’s warranty claim can’t be denied because you installed aftermarket windshield wipers that are different from OEM (Original Equipment Manufacturer) parts. Similarly, if a wheel bearing fails or a fan belt snaps and you have an aftermarket exhaust installed, the dealership would have to prove the exhaust system caused the bearing failure or the belt to snap in order to deny a warranty claim.

In these types of scenarios, the dealership should have no reason to deny your claims. If they do deny your claim you should get it in writing with their reason for not upholding the terms of their warranty.

In addition to the Magnuson-Moss Warranty Act, you also have SEMA (Specialty Equipment Market Association) working to protect your rights. Because SEMA represents U.S. aftermarket wholesalers, retailers, distributors and manufacturers, they often keep car manufacturers in check by supporting legislation that prevents dealership service providers from denying warranty coverage. This means dealerships have become less stringent when it comes to aftermarket parts that modify performance or suspension.

Q: Injen Technology

At Injen Technology, we only design, manufacture and sell performance air intake products that have been thoroughly tested to ensure compatibility with your vehicle type. Most of our performance parts are bolt-ons, and are ‘tuned’ to which give you quality performance gains without requiring engine modifications. In all reality, you shouldn’t have any problems due to installation of the parts we manufacture and sell.

However, here are a few pointers to avoid some potential pitfalls:

Make sure you install the part properly.

  • Carefully follow the installation guides and make sure you check any and all tolerances.
  • Educate yourself on the parts you’re installing; that’s half the fun of working on your vehicle.
  • If the part is outside your comfort zone, have a professional install it for you.

If you need to go to the dealership for any type of warranty issue, choose them wisely, as they will vary in how they handle warranty claims.

  • Check the Internet for reviews to see how they handle problems.
  • If you’ve modified your vehicle with our performance parts, it’s always best to work with a dealer that is performance-oriented.
  • In smaller towns, you may not have a choice of dealerships, but rest assured that you’re still protected by the law.

Arm yourself with the knowledge contained on this page, and go in with a smile. No service department wants to deal with (or help) an irate customer. Again, if they don’t want to cover your claim, simply ask them to prove what caused the failure and get it in writing. Remember, legally, you’re protected under the Magnuson-Moss Act.
