People always wanna quote the Magnuson–Moss Warranty Act but that really wasn’t enacted to protect people when doing performance mods and major suspension changes. It was to allow you to do things like oil changes brake shocks etc(normal maintenance) outside of the dealership. You have to read the fine print of your vehicle manufacturers warranty, a lot do have limitations when it comes to modifying your vehicles on what they will cover once your vehicle has been modified outside of their specifications. If a dealership denies a warranty claim just quoting this act is not going to miraculously force them work on your car probably just the opposite. You will then have to proceed with a lawsuit while your car sits there busted and hope that you can win the case. Or even get an attorney to represent you against a large corporation. If they can prove that your mods somehow resulted in premature wear of the parts on your vehicle you will lose and be out court costs etc. Not to mention your vehicle will then be flagged permanently as a modified vehicle in their system. Don’t do performance mods unless you have the money in the bank to fix your vehicle in the event of a major engine component failure.
