2010 Prius stalled on Freeway tonight - check hybrid system

Safety Recall J0V - Where is the Remedy?

 

Days ago exactly the same thing happened to me, checking the car I found that I had a fault in the engine water pump, and doing a more exact follow-up, I found that the relay of the engine water pump had failed. I changed it and the problem was solved. Check this Relay, possibly that may be the problem

Since the check hybrid system message illuminated, are you sure it was the engine water pump and not the inverter water pump?

If the car has sat for a bit does it restart? Is there movement in the inverter reservoir?

 

J0V update will make sure your car goes into limp mode and pull over "safely" if inverter fails, which sounds like you did successfully so technically you don't need the fix. Sounds like your inverter kicked the bucket.

 

Sooner or later, trouble codes will be read, and then we'll all know what we're looking at.

The recall pertains to one reason the inverter can stop inverting (when a transistor inside the inverter actually fails). But there are other reasons the inverter can stop inverting (such as a failure of its coolant pump, making it stop inverting on purpose so the transistors don't fail; fix the pump and it's happy again). So it's worth checking for that, as Raytheeagle suggested.

But as to whether to start by trying to enumerate possibilities and check them, or start by asking the car why it stopped, I would start by asking.

If there is damage in the inverter, and if it is the kind of damage addressed in the J0V recall, you can take it in for the recall and the inverter will be repaired.

 

My inverter reservoir has movement. The engine water pump relay was the problem

Check the codes yourself. If the car is storing one or more of these codes, P0A94, P324E, P3004 and/or P0A1A, IPM failure is confirmed and you're fully warrantied for 15 years/unlimited miles under the ZE3 warranty extension. This would be the failure mode the J0V is tied to.

 

Good move.

 

You need to install a new sending unit in the gas tank. Apparently they go bad and will give you false readings

Part 83320-47080

 

Just a great reason NOT to let the tank get low! Shoot for fill up at half a tank, but NO less than 1/4 and you should be fine.
