Nah, your 12v battery is probably overdue to a change. That usually happens when the 12v is dying.

 

Yep. Super common. All hybrids turn to junk when they hit 100,000 miles.
It says so in the owners manual.
All hybrids over 100,000 should just be given to me for free.

Just kidding.......
Follow Mavi's advice.

 

Stop by the local auto parts store.
They may be able to check your 12v for free.

You could check it yourself with the "turning lights on/off 3 times while holding the Info button" trick.
That is a real thing.
With car in accessory mode (NOT "Ready". In other words keep foot off the brake, press power button.)

Hold down the "Info" button and while holding it down turn the parking lights on and off 3 times,
System Check Mode screen comes up
Press the "Menu" button in the upper right corner
Diagnosis Menu screen comes up
Press "Display Check"
Display Check screen comes up
Press "Vehicle Signal Check"
Vehicle Signal Check screen comes up
The 12v battery voltage will appear in the upper left part of the screen.
Note the voltage (11.9v - 12.6v is normal)​

 

Is the MAINT REQ'D light on too? Did it come on at the same time as the others? That's strange since that light is just based on a mileage counter and has nothing to do with the other lights...unless it was already on.

 

If the 12v was at 12.5 volts with the car off, that sounds okay.

You'll probably want to get the codes read.

 

You can check inverter coolant pump function...with the car in "ready" mode, have her check for turbulence in the reservoir toward the center, back of the engine compartment with the pink fluid in it. It's sounding more like a significant failure of the traction battery.

I don't think the inverter coolant pump not working would keep the car from moving. Is the gasoline engine starting? If so, is it running at high speed?

If it's anywhere near San Fran, you might consider Luscious Garage instead. Luscious Garage | Hybrid Specialists They're kind of the national authority on repairing Prii.

 

Good luck!

 

If I were you, at the least I would get Torque app so you can do your own code reading in the future.

 

The 12V AuxBattery in my 2009 Gen II up and died at about a year ago (~ 106,000miles). First symptoms were SKS system started to get flakey and not resolved by replacing fob batteries. Eventually I had to use JumpStart system so I had the dealer to a load test, they found dying AuxBattery which they changed, and so problem was fixed. I've started using a battery-maintainer (Sears DieHard) - I connected the pig-tail to the jump-points under the hood, so now if the car is not going to be used for a few days, I can quickly plug in the maintainer, and make sure the AuxBattery is kept in good shape! hope this helps - Wil
