It's an additional potential point of failure that will be expensive to fix. Phones generally have a usable life of 2 to 5 years before people start hankering to upgrade. Cars ought to last at least 8 to 10, and ideally closer to 20. I know car designers don't actually think this way, but it would be nice if they did put more thought into making sure every part of it is easy to repair or built to last for that whole stretch instead of trying to put new-car buyers on an upgrade treadmill and telling used-car buyers to suck it up and deal.
