I've seen you make this claim about Ford many times. Is there any evidense they purpously select "corrosion vulnerable metals" to induce failure? Or is this another conspiracy theory?
I have Ford Ranger whose corrosion has rendered a battery terminal screw unturnable.
The front latch to lift hood also got stuck, which I had to release "the manual way" by fanagling a screwdriver.
There's also an ErictheCarGuy repair video on a Taurus, which one part required a torch and I recall another Youtube comment seconding the need to use a torch to disassemble the part.
Knowing you, you wouldn't accept any the statements above as evidence anyway, because you've already predetermined everything I say to be false.
And the reason I have a ranger was that I intended to install a new valve cover gasket because the old one "failed" and its a known flaw.
Not every act of inference is a "conspiracy". Actually, company dictating shaving a cent or two by using cheaper parts is a common business practice. I mean, this is the same manufacturer who skimped on spark plug threads as well, leading to recalls on that.
