While the language quotes is accurate (from their warranty language), in the real world Ford would cover most things even if there was some relationship to the tune. The language is drafted to by lawyers (like me) to allow Ford a rebuttable contractual presumption. This also can serve to deter customer from even filing a warranty.
Wording on paper is only one factor in litigation. In these type of documents, the uniform commercial code favors “the little guy” since the big company can use its power to slam terms on you that may. Or be “fair”. Also - The fact that ford is offering this through their website is likely the result of their satisfaction that it’s “safe”. The jury, and resulting public perception, would be extremely negative towards Ford if they denied a claim for a product they sold. Again - I guarantee there would be a lot of favorable/discoverable evidence and revealing information from their 30(b)(6) witnesses along with their fact witnesses.
So yes, while technically the word on the page could steer someone to believe the warranty is impacted, the reality is it likely isn’t.
