If the coolant hasn’t disappeared into the inverter (usually causing a terminal failure of the inverter), then this issue is most likely a failed coolant pump.
There are three pumps on the car:
1) Cabin heater - this pump rarely fails, mostly because the duty cycle is to only run with cabin heater. You can locate this pump by opening the hood, and looking straight down, slightly to the passenger side of the vehicle.
If you turn the cabin heater on, you should feel warmth in the hose within about 1-2 minutes, and feel the pump spinning. It’s safe to put your hand directly on the hose next to the pump, and feel the vibration and heat.
Pink fluid (regular anti-freeze / coolant) will be seen circulating in the pink holding tank.
This is a super simple test for cabin heater failure, or pump failure.
2) Motor / Inverter pump - this is located near the cabin heater pump, but it’s easy to see underneath the car (after removing the plastic underbody panel).
3) Battery pump - this one is located at the rear of the “engine bay”, slightly to the passenger side, next to the battery heater.
If either pump 2) or 3) fails, the respective component gets uncomfortably warm, and power is limited / shut off, and the Check EV System light will come on.
We have the pumps in stock.
