Your Vehicles Warranty and the Installation of Aftermarket Products

 

The Federal Magnusson-Moss Warranty Act protects consumers of aftermarket products. From our understanding, the Act states that if something breaks on your vehicle and you take it in for warranty repair, the dealer must honor your warranty unless they can prove that whatever modifications you have added to your vehicle actually caused the problem.

 

Although consumers are legally protected as stated above, the practical reality is that automotive manufacturers and dealers may have different views in regards to the installation of aftermarket parts – especially those that produce horsepower, such as performance chips, modified intake manifolds and aftermarket exhaust systems.

Be aware that some dealers and manufacturers might attempt to void warranties -- regardless of whose products are installed or how they are used.

 

We strongly recommend that you always disconnect and remove any aftermarket part that might interfere with diagnostic equipment before you take your vehicle to the dealer for warranty work.
