Failure of motor bearings is usually the result of improper mechanical installation causing undesirable forces acting on the bearings, or simply poor maintenance. Bearings should be inspected regularly for lubrication and uncharacteristic noises. Their life expectancy depends on factors previously cited. Most motor vendors typically recommend bearing replacement every two years, which I think will put a cramp in the Tesla maintenance scheme
What really is off-putting is that even if the car is well maintained and even parked. It will brick as from the degradation of the batteries. At some point the owner will have to invest in a new power pack. Not true of gas motors. I have a 66' galaxie in my driveway with its original motor its never had more than an oil and spark plug change and it has a life of nearly 50 years. I'd have bought at least 3 tesla power packs in the same time frame, even if the car just sat there.
Downvoted an honest question stated in a reasonable manner? Come on.
The last time I had an engine rebuilt (mid 1980s) it was over $1100, and this was for a 67 HP VW Beetle engine.
I find it... unlikely that you will be able to sell a 2014 Tesla model S for $30K in 2022.
Also, as btian notes below, the electric drivetrain is also much simpler than a gasoline one, so it should be in much better shape relative to non-electric cars. I'm relatively optimistic because the part that depreciates the most is the battery: and if the rest of the car holds up well, then switching the battery at a lower cost (taking into account 8 years of battery tech advancement) should make for a pretty high resale value.
