2012 Prius Plug-In: Dead as a Doornail

Check the 12 volt battery for starters.

(Think I beat @bisco, lol)

 

Yup! A dead 12V is the most likely cause I can think of. Same as with a regular car.

I think I beat him too, @Mendel Leisk. What a coup!!

 

And once you jump-start it, look to see if you left a courtesy light on, or a door ajar, or if a door or hatch switch might be mis-adjusted and not shutting off the courtesy light. Those will drain the battery.

 

Check the voltage with a digital multimeter first, see where you stand.

 

EVERYTHING usually works right up to the instant that it fails. Think a blown light bulb.

And......the charging system can often keep the car running even with no battery, until you turn it OFF of course.

It is a bit unusual for it to go completely and totally dead though. Might just be a loose cable.

 

If it's an original 12v battery, it's due. And the 12v is only used to start up. Won't affect the running. Good luck!

Actually it can and often does.
Because the charging system doesn't operate exactly right with no battery present.

 

OMG... BISCO didn't post anything yet?
as evrybody said, after jump starting the vehicle, check for doors ajar or the rear hach door

 

The 12v battery is only used to boot up the computers and close the high voltage relay.
The high voltage traction battery starts the engine, if needed.

 

grandchild, dentist and recycling day, who's got time for priuschat?

thanks for filling in fella's!

 

be careful if you jump start. cross polarizing can cause thousands of dollars in damage. pip charges the 12v while charging the hybrid battery, have you been plugging in?

 

Similar thing happened to me, I also have a 2012 but I was driving and mine completely shut down. Yes, while driving. In the end, Toyota determined my hybrid battery was the culprit and they replaced it (free of charge).

 

Geesh, how many miles?

This might be the first PIP battery failure?

 

WOW!!! Glad it was a total fail, though, and you got a new battery with no arguments.

I wonder what's happening with @old5ten.

 

i'll be curious to know how many miles as well. i can't recall anyone else replacing a battery.

 

That the first I've heard of for sure, but I think I remember once reading that someone said they thought they'd heard of one. Which is about as nebulous as you can get.

 

check the 12 vo............................. oh never mind....
im going to suggest the blinker fluid from now on..
