In this video, I show the two common issues/failure modes for the Tesla Large Drive Unit. This applies to of course the RWD and Performance variants of Tesla Model S and X from 2012-2021, as well as the 2012-2014 Toyota RAV4 EV, and 2014-2017 Mercedes B-Class ED/B250e.
The most important thing to do on these at least once a year is to inspect the rotor encoder sensor (aka "speed sensor") for signs of coolant or corrosion. If you happen to be in the Portland area and want me to inspect your speed sensor for free, feel free to get in touch!
