Prius (2004-09) :: 2005 Not Starting After Replacing 12 Volt Battery
My Prius has 150k miles on it. We didn't drive it for a few days and when we went to turn it on,it wouldn't work. We were able to jump start it a couple of times, however after that we ended up having to replace the battery. We purchased it brand new from toyota. Then, the car wouldn't do a thing (No sounds, no lights, other than the red amber power button and the flashing check engine light, which was not on before.) We ended up having two blown fuses and we replaced them today, one was for the battery.Now the lights are on, but the car still won't start. It will cost over $200 to have the car towed and I am really trying to avoid that right now. I don't know much at ALL about cars. but I'm trying.

I am not sure if I need a new fob.
My smart key quit working. I have replaced the battery, and checked the button under the steering wheel. The little red light on the fob does not blink or light up when I push it. I think I recall this light coming on when a button is pushed.

We just got our 2012 Camry XLE about 1 month ago. Today, the smart key push start didn't work; the brake pedal seemed like it was seized, but the green (key) light did manage to come on, indicating it knew the key was there. When I pressed the start, all of the dash lights were flickering, but the car wouldn't start. Was towed to the dealer, who ran a diagnostic that indicated the battery had failed (the options for the diagnostic are pass, charge, and fail). They installed a new battery and it seems fine.
One of the doors wasn't completely closed overnight - would this have caused the battery to be done? I could see if it caused the battery to drain, requiring a boost / charge.

I have a 2007 Prius 2, the key will not open the doors, so I went to the store replaced the remote battery but it is still not working. The light on the remote lights up as usual. I can get in using the small metal key, the car starts and everything seem to be working fine with the smart key plugged in. The 12v battery seems to be fine as all the lights work when the car is off. What this might be?
View 5 RepliesPrius (2004-09) :: 12 Volt Battery Drain
I started having a problem last week when my 2007 Prius was setting for two days while I was using my pickup truck. Found the 12 volt battery dead so I disconnected it and tested it with a battery load tester. And it showed it was bad. Well Ok, that figures, since it was an OEM battery and ~6-7 years old.
I have another 2007 Prius here for body repairs so I took the aftermarket (newer) battery out of it and topped the charge off in it. The battery load test indicated it was still a serviceable battery.
Put it in the car and cleared the red triangle, etc.. Everything was fine.
Since I was still going to be short one battery, I contacted Battery Systems, my shops battery dealer and ask them to drop off a new Yellow Top Optima that fits the Prius (FYI my shop price is $159.96). I would be a couple days til their deliver truck would be here and again I left the car sit for a couple days and drove my truck. On the day of the delivery, I had an appointment and drove the Prius, about 15 miles. No problem. Left it at in a street parking space for about 2 hours. Came out and all systems were dead. Nothing. Dome light was the only indication that the battery was so low that it was very dim. Head light were off and I hadn't used them while driving.
I called for road service and got a jump start and the systems came up and I was able to clear the Read Triangle when I got home by turning the car off and back on again.
The new Yellow Top Optima arrived shortly there after and I installed it. Drove the car for 6 days and this morning everything was fine when I drove to church and left it, head lites off (never had used them), came out 2 hours later and when I started the car, I got the Red Triangle and Ready but continued home. I turn it off and on again but this time I got no Ready but the Triangle and the whole sting of check light. Could only get it from park into neutral. Nothing else. Wouldn't clear.
Using my Torque Pro program, tried to read the ECU and it indicate no codes stored, Several tries, no codes or history. Called friend who has reader that will read the CAN Bus and he managed to find an odd P0503 code having to do with a speed sensor. Cleared that and the Triangle went out.
In the end I went and checked the voltage of the new battery and it was only 12.01 volts. I put the load tester on it and the condition is fine. Just the charge voltage is low.
Prius (2004-09) :: 12 Volt Battery Would Not Boot Up Car
2009 Prius 36,000. Driven at least 30 miles per day. Two months ago, 12 volt battery wouldn’t boot up car. Crazy messages on MFD like “Park on level surface and apply parking brake.” Jump started and drove car to the dealer. No problems found. Three weeks later, same problem. Again, no problems found but dealer replaced the battery. About three weeks later same problem except this time got the friendly Triangle illuminated. Drove to dealer and left car. I have an extended warranty so Im not too worried about any costs. The next morning the triangle was NOT lit and the only error code was low voltage. No interior lights on and current draw is normal when car is parked.

I recently discovered that the compartment where the 12 volt battery is located had water inside. I checked for leaks none found. I also found a drain plug underneath, to drain the water out. Where might the water be coming from.

I've had a 2004 Prius for about one year. It has ~120K miles and has been a great car. We left a light on, and the 12V battery died. We jumped it and everything seems to work fine, except now the air conditioner isn't working.
View 2 RepliesPrius (2004-09) :: Red Triangle And VSC Warning - 12 Volt Battery Not Charging?
I've seen this a couple times but always made it home with the Red Triangle and VSC warning. A year ago, I blamed it on the OEM 12 volt battery and eventually replaced it with a Optima Yellow Top. No more problem until today. Day time driving with my Plug-in Supply 10k rechargeable conversion performing normally. City driving raining but normal Western WA conditions. Red Triangle and VSC warning. Other systems operating normal.
I knew, from previous experience that the Prius operating systems would continue to work only until I turned it off. I did turn off the Plug-in Supply controller to isolate that system and observed that the OEM traction battery was at a fairly high state of charge and the ICE was still providing the normal amount of assist to the traction battery through normal street and driving conditions.
I should have driven the 20 + miles to get home, even with the Red Triangle warning. I had done that in the past with the old OEM 12v battery. But I needed gas and went to a station and turned off the system ICE out of habit. Sure enough, the system wouldn't go back into Ready but would go from Park to Neutral. Since it was rain hard now, and I was calling my road service, I ask for a Flat Deck Tow home rather than a jump start.
As soon as I got off the tow truck I put my battery charger on the Yellow Top and it only read 11.7 volts. It's still on charge now. Now I'm wondering why the power conversion system wasn't charging the 12 volt battery or is my 1 year old Optima bad?? Or is there something about my driving conditions/plug-in conversion that is effecting the charge of this battery. I did a 2400 mile road trip to So. Calif and back to WA without any problems. Car has just 98169 miles right now. About 10k miles on the Plug-in Supply conversion.
Prius (2004-09) :: Master Caution Light / Dead 12 Volt Battery
So our '06 Prius has been very, very reliable, and we have a bit over 105K miles on it now. But we have a problem that the dealer hasn't been able to confirm, much less fix.
Probably three months ago now I began to notice that, from time to time, when I started the Prius, the master caution light (red triangle) would come on for 2-3 seconds. At no point did it stay on, and at no point did the Prius fail to start. So, it was an intermittent caution light of brief duration.
Then we had a bad storm coming (Sandy) and although it wasn't nearly as bad here (N. VA) as it could have been, I put the Prius in the garage, and it sat there for three days. When I went out to start it, the 12 volt battery was dead.
Fortunately I always back into the garage, and so jump starting the Prius - although it was my first time doing so - was no problem, and I got it to the dealer that morning. They tested the battery, and it was fine. They checked the codes, and all was well. It was as if the battery had never died. AND we stopped seeing the master caution light ... until two days ago, when my wife said that she saw the light a couple of times when she was out running errands.
Is it possible to have a problem with the 12 volt battery and/or electrical system that doesn't show up in the codes? And am I wrong to lose confidence in this very, very reliable car??

I have a 2007 Prius. Last night, my neighbor said he thought he heard my car alarm going off. I used my car fob to turn the alarm on then off to ask him if that's what he'd heard, and it wasn't. Seems he mistook someone else's car for mine.
Today, I find my car's smart key functionality is limited. I can keep the keys in my pocket and still unlock and lock the doors, but the engine won't turn on, instead displaying the key symbol on the dashboard; I need to insert the fob into the slot instead. None of the buttons (lock, unlock, alarm) on the fob work. The smart key button under the wheel is protruding, as I believe it should.
Prius (Gen 1) :: Car Sat Idle - 12 Volt Aux Battery Died
Well, since I had to fix the traction battery. The car I bought was a salvage vehicle that had been rebuilt.
On pesky problem was found after I'd had the car for about 4 months. I let it sit for three days. When I went to start it nothing happened. The 12 vdc Aux battery died. It tried charging it and it wouldn't charge. I bought a new aftermarket battery at WalMart and installed it. Merrily being led down the garden path I figured I'd not see that pesky problem again.
I was wrong. It continued. About the time I was going to tackle it, I moved and that took the next 4 months and the Prius sat idle when the HV Traction battery error cropped up.
This week I figured since all the carpets and shrouds were out of the trunk for the battery repair I'd look at the luggage courtesy light, it was the most obvious cause of an error. Sure enough the lamp would not shut off even though it seemed to operate correctly. It pulls up ground and turns on the light.
Prius (Gen 3) :: 2011 - Dead 12 Volt Battery After ECU Update
I got the ECU Update Friday.. Today my 12 volt battery died. (got it started after a jump)..Any correlation?? Toyota service days no. Is there any kind of a warranty on the 12 V battery? 2011 with about 40k on it seems way low for the battery to die. No changes in driving habits since ECU update either...
View 7 RepliesPrius (2010-12) :: Charging A Dead 12 Volt Battery
My dad's Gen III has been sitting garaged for almost a year now, and of course the 12 volt battery is dead. Firstly, it's sitting in a one car garage, and secondly I have a Gen II so a straight jump isn't possible. I have a trickle charger that should be able to bring the 12 volt back up in 15-19 hours, but here's my question:
Maybe I'm being lazy, but I'd rather not deal with climbing in the back to release the hatch and running an extension cord so I can get the charger close enough to hook straight up to the battery..
Prius (2010-12) :: OEM 12 Volt Battery Be Replaced At What Voltage?
As our Pri age, sooner or later the 12 v battery will fail and at exactly the wrong time. So perhaps preventive maintenance means replacing it just before failure. What has been the experience of other owners of 2010's as far as failure goes?
