@Santapez agreement with some of you post but also not sure where this conspiracy is coming from. For clarifciation, there is no maintenance cost. Rotate tires and change cabin filter. If there is something to fix then yes, it may be expensive but any expensive car is expensive to fix (as you note). Sister's 2018 BMW X3 fuel pump and control module failed. I didn't ask how much. My guess is $1,000+
And it seems like you are just referencing the early Model S with the 1st gen MCUs. The cost is $1,500 to replace with MCU2 and get up to speed with a Model 3/Y. That's if it fails.
Battery failure rate.... (I'll try to dig up a vetted source)
