> They cannot void your warranty, in whole or in part.

I understand what you're saying, but your core beef seems really pedantic in context.

Yes, the warranty terms aren't abandoned, but...

..."voided" isn't a defined term, it's not used anywhere in the Magnusson-Moss Warranty Act (from my scan), I sourced an attorney using "voiding" in a more casual sense, and you even acknowledge that in practice, you're screwed if you tune your car, get caught by the dealer/manufacturer, and have issues with relevant components.
