Still a NOOB owner of my 2017MS, but over the past 20 years, I've only purchased/owned used cars; BMW, LEXUS, Buick, Chevy and those vehicles NEVER received any sort of update/support SANS mandated recall programs. Consistently handling the basic ICE maintenance routines, all cars lasted well past 100k miles. However, in the later years, spend on break fix always increases as rubber parts begin to break down.
So, when I think about my MS and reliability, I tend to consider the major systems which DIFFER from ICE cars. Similar systems, such as the suspension, door handles, windows etc. All should have similar reliability patterns...except where Tesla has done something substantially different; like the door handles
From what I have gathered in my initial research into some of these systems
Main Battery - Data linked in this forum indicates 20 year life of pack, but with capacity degradation over that time.
Brakes - Regenerative braking should substantially extend the life pads and rotors.
Powertrain -
see fortune article
Another thing which sets the Tesla apart is with respect to all the various "electronic" systems. Unlike traditional manufactures, who must integrate disparate systems, Tesla has full control (and blame when it doesn't work).
Just came across this
presentation, which is really quite interesting.
