IMO it’s because they keep making them more and more complicated.
Or as I like to say......more crap that WILL break eventually.

My 2019 F250 missed another Bug!
My 86 F150 caught fire in the Colt Manufacturing Plant parking lot when it was only a year old [fuel pump leak]. The fire dept was there in minutes and saved the truck, there was a auto parts store across the street where I got a new fuel pump and replaced it in the parking lot. I was able to drive it home that day.Simple fix, I doubt I could do that now.
