Prius (Gen 1) :: Auxiliary Battery Drained - Random / Multiple Cylinder Misfires Detected
I left the key on and drained my auxiliary battery(It was weak before) and when I jumped it it started and then shut off after ~20 seconds. I tried various different things and all I succeeded in doing was draining my HV battery from starting it so many times. So I disassembled the pack and recharged it and now it starts and runs but it is misfiring. It throwing 4 codes:
P0300: Random/Multiple Cylinder Misfire Detected
P0302: Cylinder 2 Misfire Detected
P0304: Cylinder 4 Misfire Detected
P1305: Ignition Coil 2 Primary Feedback Circuit
I inspected the igniters and plugs and they seem to be OK and I'm not sure where to look next. I'm not sure if the battery issue is related or not but I did replace the auxiliary battery.
Prius Plug-in 2012-15 :: 2014 Battery Drained Although Charged Overnight
I went to drive to work today and found that my battery was drained. None of my interior lights were on and I'm 100% sure I turned the car off last night after I backed it into the garage. Last night I drove the car home and was mostly on EV, but drove the last 3-4 miles on ICE. I had the car charging overnight too. This morning, with the battery dead and the cable plugged in, it was making a click sound near the fuse box when I tried to start it.
The passenger seat's heater was on (I think) and I don't think any of the doors were ajar. The only door that could have been opened would be the driver's but I don't think it was half closed.
Lexus GS 2013+ :: Battery Drained Itself Overnight For No Reason
I went to start my GS in the garage this morning and nothing happened. I couldn't even open the trunk or turn on any interior lights. I checked the battery with a multi-meter and it shows 5.25V. So for whatever reason, the battery drained itself overnight. I'm positive no lights were left on or doors left open. So this is a total mystery to me.
What might have caused this? Also, how to open the trunk after the battery dies. The car has been great for the first 7k miles and problem free until now.
Saturn - Vue :: Key Left In Run Or Accessory Position Overnight And Battery Drained - Car Will Not Start
I have a 2003 Saturn Vue. My wife left the key in run or Accessory position overnight and drained the battery. Now that I have recharged the battery the car will not start. The dealer where I bought it said to turn the ignition to the run position for an hour to reset the security system. Then turn it off and start it. They said this would reset the computer and reenable the fuel pump. Didn't work.

Just had my first battery boost for my year-old Prius 2K10.
This morning I went to start the car, it didn't open the door for me, then I had all troubles in the world turning the key ... And obviously nothing was opening, no lights, nothing.
I had my car boosted. First time they put the booster, I couldn't start the car (everything showed up but starting the car didn't start the conventional motor - the lights were all on). They unplugged it (everything disappeared yet again) and plugged it back in ... Then I could start my car. Of course, everything was reset: time, trip meters, everything.
That's where I noticed my battery indicator was half-full.
Prius (2010-12) :: 12V Battery Fully Drained / Car Won't Jump Start Either
The 12V battery must have been drained completely over the weekend. None of the lights (interior and exterior) are working. The car won't start even using jumper cable. I guess the 12v battery must have some juice remaining to power up the computer in order to jump start the engine. Am I correct in this assumption?
My Prius is only a little over three years. What is the warranty on the 12v battery? I read that the OE battery is not the best. How long would I expect the OE 12v battery to last?
Prius (2010-12) :: Battery Drained After Left Air On, Loud Sound That Continues
About a yr ago I bought a 2010 Prius with about 36,000 miles on it. Now I'm just about to crack 50,000. Late into the winter I began hearing this sound and thought it was odd. I figured it had something to do with the fact that it was winter and the engine/battery were working together to warm the car up as well as charge the battery. I took it to Toyota this past week and of course the "Service Experts" claimed this was "normal" as one of the managers owns a prius and claims they all do this. I know this to be false due to having owned one for a year now as well as reading up on a lot of the great info poster in here. Now in the defense of the mechanic that day, my battery was pretty well charged. The sound isnt nearly as harsh when the battery stays at or around half way charged.
Today while doing some cleaning inside my car i left the air on. As a result my battery drained low enough for the battery to begin charging. This brought on that miserable sound that continues to get louder and more noticeable with time.
Prius (2010-12) :: Battery Charge Down To 4 Bars Overnight
Should I be concerned..I have been noticing my battery is charging down overnight. I checked and all lights are off. It does charge immediately in the 10 mile I drive to work..but I am concerned why overnight it should be discharging.
Another Question - The right/left indicator sound is very muted..is that normal? Like, if I have the indicator on to merge into traffic, I am not sure it is as I can barely hear it chirping..
Prius (2004-09) :: 2006 - Battery Won't Working Properly After Two Month Rest
We spend summers away and our 06 Prius stays in the garage. I connect a battery minder and it keeps the 12v battery charged with no problem. I also turn off the switch under the steering column that works with the remote.
When I started the car after two months and driving for a few blocks, I noticed the MFD showed the battery at a low of two purple lines. After a while, it charges up normally. The car has 47000 miles and the 12 v battery has never been changed. Would that have something to do with it or am I being concerned over nothing?
Camry :: 2010 - Trunk Remained Open - Light Might Drained Battery
For some reason, I didn't close my trunk door good last night and I discovered that the trunk remained open all night long, about 12 hours. I am worried that the trunk light may have drained my battery. The car started up just fine with no delays or odd noises.
View 3 RepliesPrius (Gen 2) :: Headlights Stayed On And Drained 12v Battery
I was waiting in the mall parking lot. I never got out of the car, so the headlights stayed on and drained the 12v battery. A good Samaritan "jumped" the car with a portable jump-start device. The next morning, I hit PriusChat and found out about the system diagnostic. It shows that battery has one foot in the grave and another on a banana peel - 12.1v at rest and dropping to 9.8v with the dome light on for a few minutes! Back to PriusChat to research replacement batteries, their sourcing and installation.
I have an Optima Yellow Top on order, as well as a pair of those jump-starters (One for the Pruis and one for the pickup). Before I install the new battery, should I have it trickle-charged overnight?
Prius (Gen 2) :: 2006 - Battery Drained, CEL Lights Came On
My wife and I bought a 2006 prius almost a year ago and after going away for several weeks we came back with the battery completely drained. I was able to charge it back up. But after that, on the very first drive, most if not all CEL lights (Check engine, the triangular sign, ((!)), VSC) were on. I figured it was probably related to the battery that got drained since we had no problems before, and after all these warnings came the vehicle does not drive any different.

Battery was fully charged when left it at night that in the morning the battery level would be less. This happened to a friend of mine twice so far.
The first time it happened she accidentally left the lights 'on' which supposed to turn off on their own after 30sec. But in the morning she's only left with 2 bars from fully charged. And a week later it happened again but without leaving the lights 'on', from almost full charge to 3 bars of battery in the morning.
Prius (2004-09) :: 12V Battery Drained And AC Stopped Working
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.

Loaned my car to a friend who left something on and drained the 12v battery. Some "good person" tried to jump start the car and was unsuccessful. When I got there I attempted to jump start from the front and direct to the battery in the back, both unsuccessful. After having it hauled back, I charged the battery with my charger, no luck. When I put the keyfob in, press the break, and push the power on button; get green light on the power on button and a check engine light on the panel. This 12v battery is original battery and car has 100K miles.

I have a 2008 Prius and have been thinking I should be changing the auxilliary battery soon as a preventative measure. I've changed plenty of batteries in other vehicles before but I was wondering if there's anything that's much different in these cars that I should be aware of?
View 9 RepliesPrius (2004-09) :: Auxiliary Battery Running Down?
I left my car for a week in the garage and the battery ran down. I had it re-charged but now even running the radio for a ten minutes with engine off runs down the 12v. The panel check says that its charge is over 12.4 v. What is going on? How do I prevent having to jump start the car every day or so even after running for 20+ miles at freeway speeds?
View 5 RepliesPrius (Gen 2) :: Hybrid Battery Drained / List Of Codes Scanned
I'm hoping I can get some diagnostic insight into a problem I just started seeing on my 2007 Prius. I have had the Prius for a little over 4 years. Currently around 123K miles.
Starting two days ago I noticed when I started driving that the engine was constantly running and when pulling out from a stop sign just up the road from my house the acceleration was sluggish. I look at the MFD and see the hybrid battery is nearly drained. Unusual because it was blue or green when I parked the night before. Driving for a few minutes, the battery fills back up and driving is normal. The only warning light is for a tire pressure sensor which just started to come on that day. Over the last two days I get the same thing at start up. Hybrid battery is drained. Lights aren't left on over night. Tire sensor light is constantly on but I checked the tires and pressure is good all around. Nothing plugged in anywhere to drain battery. The 12V battery was replaced maybe a year or so ago with an Optima yellow top, so not likely the issue. I checked diagnostic codes in the MFD and came up with a lot of codes:
LAN Monitor EMV:
01-DB 190- 40- 5
01-DE 178- FA-1
01-DB1F1- E5- 4
01-DB 110- 8A- 7
01-DB 178- 46- 3
LAN Monitor NAVI:
01-E3 - 00- F
Prius Plug-in 2012-15 :: Car Left In Idle For Two Days - 12V Battery Drained
Yesterday when I went to start my week old PIP, the battery was drained. There was no power to start and no power to the dome lights etc. I got out the owners manual and on page 594 there were instructions to jump start which I did. I drove it to the dealer and they checked it out. They said the 12V battery state of charge was 50% after being jumped and driven for 30 minutes. They then charged it to a full state of charge. They couldn't find any other drain overnight.
I am trying to determine why this happened. The reason was not apparent. No interior lights were left on. There were no other electronics attached. We had driven the preceding two days in EV mode virtually exclusively. I don't recall if the ICE came on. The car sat unused for 36 hours. It had been plugged in to charge the traction battery and it charged via the timer without any apparent errors.
The service tech wondered if the battery had been fully charged prior to delivery. I know the traction battery had not been fully charged because I was anxious to take delivery. Could this be a consequence of driving in EV mode almost exclusively?
