Default 12V battery?

Guys,

I am a new Prius owner. I have a 2004.

A few goofy things happened to me today:
1) The digital speedometer completely went out so I cannot see if I'm in P, R, N,D nor how fast I'm driving.
2) I tried to pull the key fob out of the port and it wouldn't come out.
3) I also got a triangle icon on the screen.
4) The car seems to run fine but I'm afraid if I'm going to stall on the road.
5) When I tried to shut off the car it ignored me. Car wouldn't shut off.
6) The locks were acting goofy.
7) Sometimes I would hear clicking coming from the back of the car.

Question - Do you think it is the battery?
If so, where is the best place to get it?

Thanks in advance.

Yes it could be the battery but........

If it REALLY will not shut off, why would you NOT GO TO A TOYOTA DEALER to see what gives ?

What are you going to do with it tonight......just leave it sit there in the ON state with the FOB stuck in the slot ??
You'll be lucky if someone doesn't drive it off.

Well since no one answered and I did research myself I will put this out there to help anyone else with similar problems.

There is a recall for the Combination Meter. The Combination Meter is the LED cluster display (shows how much fuel you have, speed, whether you are in D, N, or R and also all the lights like Check Engine, Temperature (little snowflake), Red Triangle, Seat Belt, etc). It has been known to go completely blank which completely freaked me out. Somehow, in my case, it came back on for unknown reasons. Just be aware that there is a recall and you should contact your nearest Toyota Dealer to get it replaced hopefully for free.

Additionally, I also found a way to reset your system. You simply unplug your battery for about 30 minutes. You would unplug the little connector and that should help bring the Combination Meter back on.

I didn't have to check the battery or replace it for now but if the problem persists, I have learned the battery might also be the culprit.

Lastly, for the car not wanting to shut off. You would do the following: Push On/Off button for 3 seconds. That will shut off your engine. Then push button again 2 times quickly. That will completely shut off all your power so that you can rest assured the car indeed is completely turned off. Then the key will easily slide out of the key fob port.

I hope this helps someone, someday.

Cheers!

A 12 V battery getting weak can cause all kinds of strange things to happen......including having the vehicle STOP right in the middle of the freeway. You REALLY should get it checked out.

I replaced the 12V battery. I bought from Toyota dealership and replaced myself. $200 fix. Problem solved. Took care of all my problems above.
