Here is our latest video on how to check the speed sensor for leaking coolant in the Tesla Large Drive Unit in your 2012-2014 Toyota RAV4 EV. If your car is NOT on the Toyota Platinum extended warranty (VSA), this information is critical to your finances. If you do have the Toyota Platinum warranty, you will want to check that sensor before the end of your warranty, or if you prefer to not have the motor quit in the middle of a freeway.

Coolant into the motor and inverter assembly can (and has) destroyed the motor, so that it cannot be rebuilt. PERIOD. Don't be that guy or gal. Check it regularly.
