You take a software engineer's point of view. The people who build cars, especially at established car companies are mechanical engineers however. And they design consumer technology, they don't design military vehicles or ambulances, so their main goal is not reliability, never has been. Cars have constantly gotten harder to repair, more brittle, and if a repair is needed, you often have to, instead of being able to swap out a $5 component, replace larger components that the $5 component is part of. This is by design as replacement parts is a high margin revenue source for the car manufacturers. Why should the software side of things be any different?
