This! I work w/ large mainframe computers, disk arrays, switches, anything IT basically. Your high end hardware, pretty much everything has a redundant component, down to the power supply. What's not redundant, software. Sure, you can have HA systems, but that's at the OS level, applications fail! Even OS' fail, rarely at the level I work at, but they can fail none the less.
When a manufacturer pushes out a fix, like Tesla does, it opens up Pandora's Box to other bugs/issues that need to be addressed... same as Apple with their IOS updates, same as Android w/ their OS upgrades... so on and so forth.
