That is the biggest thing right there. If they cannot prove it cause the failure then they cannot void the warranty. For example, they cannot deny you warranty work on your peeling headliner just because you have aftermarket wheels and brakes installed....an aftermarket part has to CAUSE the failure of the part have warranty work done.
