Dear Consumer:

Using Webasto or other quality brand name aftermarket products does not void vehicle warranties.

Consumers who purchase aftermarket accessories are sometimes told by an automobile dealer’s service representative or mechanic that after-market parts or products will “void the warranty” with the implication that only the car manufacturer’s own brand may be used. This, of course, tends to cast doubt on the quality of the after-market products.

This claim is simply and absolutely untrue. Under the Magnuson-Moss Warranty Improvement Act a vehicle manufacturer may not make its vehicle warranty conditional on the use of any quality aftermarket accessory unless the manufacturer provides the system free of charge or the Federal Trade Commission (FTC) has specifically published that only vehicle manufacturer’s product may be used.

To challenge a false claim, ask the person to put it in writing or provide the product free of charge including installation. If they refuse to give you a written statement, there may be a violation of Federal law.
