Legalities of Aftermarket Installations – Will it void my factory warranty?
The quick answer is "no," here's the story behind that. The Fear: You want to upgrade your vehicle with aftermarket equipment, like a radar detection and laser jamming system, but you're worried about putting the vehicle's warranty at risk. It's no wonder. How often have you heard someone at a dealership say that "installing aftermarket equipment automatically voids the manufacturer's warranty?" This common misconception has been repeated frequently enough that it is widely believed to be true - THOUGH IT IS COMPLETELY FALSE. The Truth: Most vehicle owners are unaware they are protected by federal law: the Magnuson-Moss Warranty—Federal Trade Commission Improvement Act of 1975. Under the Magnuson-Moss Act, aftermarket equipment does not void a vehicle manufacturer's original warranty unless the warranty clearly and conspicuously states that aftermarket equipment voids the warranty. Most states also have warranty statutes, which provide further protection for vehicle owners. In other words, that means a dealer can't wiggle out of his legal warranty obligation merely because you installed aftermarket equipment. Check the owner's manual to determine if any aftermarket equipment automatically voids your vehicle's warranty. The language you are looking for likely appears under a heading such as "What Is Not covered." Although the language seems negative, remember your vehicle manufacturer is simply saying he does not cover the aftermarket products themselves. He is not saying that the products would void the vehicle warranty. Vehicle Dealers Obligations Suppose you modify your vehicle, and then it needs repairs while still under warranty by the dealer. Without analyzing the actual cause of the problem, the dealer attempts to deny warranty coverage. He decides based on the fact that you've installed aftermarket equipment—a convenient way to avoid incurring low-paying warranty work. An example of how ridiculous this can get is a man who was denied warranty coverage by a dealer on his power door locks because he had improved his exhaust system. It sounds unbelievable, but it happened - because that man did not know his rights and challenged the dealer's decision. FACT: A dealer must prove - not just say - that the aftermarket equipment you installed caused the need for repairs before he can deny warranty coverage on that basis. Your Rights Point out the provision of the Magnuson-Moss Act to the dealer. It requires that he explain to you how the aftermarket equipment caused the problem. If he can't—or his explanation sounds questionable—it is your legal right to demand he comply with the warranty. FACT: There is recourse if you are still unfairly denied warranty coverage. The Federal Trade Commission administers the Magnuson-Moss [...]
