I experienced the dreaded Check EV System message. There was also a brief Battery Overheat Message displayed as I limped home less than one mile in Turtle Mode.

I towed it to Crown Toyota Ontario as they were the closest Toyota Dealer with a RAV4 EV Certified Technician. (I live in Las Vegas) The report came back that it was the Drive Motor Water Pump. The estimate is $1,000 for the pump with 3 1/2 hours labor.

Has anyone else experienced this problem or am I just the lucky one?

The pumps are known to fail occasionally. There is one pump for the main coolant loop that cools the drive unit, charger, and DC-DC converter. There is a separate pump and coolant loop for the battery pack. There seems to be some conflict between your symptoms and their estimate since there are two different pumps for those functions.

There is a third pump for the cabin heater coolant loop.

The MSRP of the pumps is only $585.
