Magnuson-Moss Warranty Act

Does installing a 4D Tech product void my vehicle warranty?

Installing an aftermarket product does not automatically void your vehicle's factory warranty. Under the Magnuson–Moss Warranty Act, a manufacturer generally cannot deny warranty coverage solely because you used an aftermarket part or had work performed outside its dealer network.

A manufacturer may deny coverage for a particular repair if the aftermarket part or its installation caused the problem. That does not mean the rest of the vehicle warranty disappears. Follow the installation instructions for your exact vehicle and contact us if a connector, bracket, or system does not match the photos or video.

For example, bending the connector-protection bracket exactly as shown in our verified Maverick/Bronco Sport instructions does not, by itself, void the vehicle's factory warranty. Damage caused by improper installation may not be covered.

What if I have a warranty concern?

Tell the service provider what was installed and describe the problem. If they believe a 4D Tech product or its installation caused the failure, ask which part failed and how the installation caused it. Contact our team with the vehicle, product, and service findings; we can help review a product or installation question. The vehicle manufacturer's warranty and our one-year product warranty are separate.
