There should not be any reason for the motors to fail as such. I bet its the bearings or perhaps the rotor position sensors (if it has those). Probably not designed to be repaired so they swap out the whole thing. No mention of the inverters or other electronics though.

EDIT: The link had this on the motors:

"Some early Tesla Model S EVs were known to have issues with their rear motors. This particular Tesla suffered from this. The rear motor was replaced thirteen times, so if we include the original that it came with, that's fourteen motors over the course of 1.2 million miles.

Most of the replacement motors were actually refurbished units and the problem there is that Tesla didn't know the real issue so it didn't know how to properly fix the motors. Some of these replacement motors failed very quickly. Some were covered under warranty, while others were not."

So, not a problem that should be seen on later ones. Early production design issue or mfg issue with the motor it would seem. Sort of like the thing used to be said to not buy the first model year of a new vehicle as they worked out the bugs.
