Consumers of aftermarket products are protected by The Federal Magnusson-Moss Warranty Act. The Act states that if something breaks on the car and the consumer takes it in for warranty repair, the dealer must honor the warranty unless they can prove that whatever modifications have been added actually caused the problem. Please keep in mind that towing in anything higher than level two and hard driving in levels four and five are not recommended.
While consumers have strong legal protection with regards to their vehicle’s warranty, there is also a practical reality that different automotive manufacturers and dealers have greatly varying views on aftermarket products, in particular those that produce horsepower, such as performance enhancement chips, modified intake manifolds, or aftermarket exhaust systems. There are dealers and manufacturers that will use the presence of a horsepower upgrade to void the vehicle’s warranty, regardless of whose product the customer is using. Any aftermarket company that does not acknowledge this is misleading the consumer.
Bottom line: while the law protects the consumer and provides for enforcement of the warranty, it is very difficult for most people to hire an attorney and fight a voided warranty.
