google Tesla big drive unit coolant bypass - a well known failure and the aftermarket has had to make a fix for itBut there are already plenty of Mach-E's with over 100,000 miles without a drive unit failure. As much as I can tell from this forum, drive unit failures are far from common.
There are drive unit failures on those Munro worshipped Teslas too.
long / short of it the rotor has coolant inside it and the seal from the end cap where the coolant enters fails and fills the drive unit with coolant eventually frying the inverter
