I did a quick check. my 05 truck was 7/70. 2014s seem to be 5/100,000. Should be fine. Maybe there's more to the story
Maybe it's in the details. Electrical may not be under powertrain.
Either way, that's a crap warranty. I don't care how it's structured, if there's a way they can screw you after 2 years, it's wrong.
I remember sitting in the dealer buying my '05 that January, with the big fat sales boss sweating over me telling me I should buy an additional warranty to cover things like the "engine computer" failing. That statement and his slavering delivery almost caused me to turn down the deal. I said "why would the computer go bad?"
I guess that sort of thing does happen, but to organize the warranty to exclude responsibility is BS
