Would you feel different if he were just sitting in the truck hitting the button to fold it and the motor failed? I imagine that could fall into some abuse category if they were some how able to look at how many times the motor cycled, but that depends on how many cycles it was rated for.
As far as forscan changing something in the truck. Someone with more experience correct me, but doesn’t it literally just check a box yes or no, it isn’t like it is writing the code to make the option possible. Then it should follow all the same things mentioned above, which would put the same west and rear on the motor as if it were a factory option.
So if what I said was true: that if the mirror has an electric fold (not auto) from the factory and if forscan only turns on an option that was turned on before then it probably should be covered in my opinion. But also in my opinion, I don’t agree with lying, hiding things, “cheating the system”, etc.
For what it is worth, I modify things and I don’t even consider warranty coverage as an option. Having said that, if all (100%) of people cheating the system went away, the vehicle price wouldn’t be cheaper.
