The thing that bothers me is the gradual realization that my Tesla is not entirely ... virtual. There are mechanical thingies, and pipes & hoses, and gaskets and bolts.
Now, if you follow Sandy Munro's teardowns, compared to say an Audi or Mach-e Mustang, Tesla vastly reduced the parts count, and the fewer parts, the fewer problems. And they keep eliminating more all the time. That's one way a 2021 is better than a 2018. But it's not entirely like in my initial dreams, with just a big battery, a few cables, motor(s) and computers. I was confident I'd drive my Model 3 "forever". Maybe a little less confident now. And I'll try out the emergency braking
IMO, the bill of material (BOM) on a Tesla is way less than even the simplest of ICE vehicles.
The obvious lack of a normal engine, clutch/torque-converter, transmission, differential (there is still a CV though) obliterates 90% of the parts that commonly fail/wear on ICE vehicles.
But also consider that...
The entire emissions system is gone...
the HVAC system is way simpler (especially with the heat pump)...
Even without a mega-casting the chassis is still pretty good compared to many competitor vehicles...
There are zero relays (I think... correct me if I'm wrong) and fuses...
Interior controls is just one monster touch screen instead of foddley knobs, momentary buttons, and levers. Hell there isn't even an ignition switch.
So yes, you still have issues with ball joints, suspension, some cooling hoses, doors, windows, steering rack, active and passive safety, tires and unfortunately this brake line problem. But a Tesla Model is soooo much simpler. And presumably easier to own in the long-run. Ironically the worst part of a Model X is the goofy-azz doors, which is a complexity that probably doesn't need to exist except Elon wants the X to be coooooooool.
The battery is the looming elephant-sized-repair, but so far the battery has proven to be fairly reliable across the model lines. Like I'm not seeing motor, inverter, and other crazy-weird EV-specific repairs in people's experiences so far. It's mostly nasty panel gaps and rattles... and in this once case a busted brake line.
