Lexus GS 2013+ :: Battery Drained Itself Overnight For No Reason
Nov 11, 2012
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.

I just bought a certified 2010 Prius and have had it for 3 months now. Twice within one month, there was absolutely no power to start the car because the aux battery went dead overnight. I'm pretty sure I didn't leave any lights on and don't think I did anything differently when exiting the car for those 2 times. I took it into the dealership, and they couldn't find anything wrong. They said the battery was good. What is draining the battery overnight?

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.

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.

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.

I have a VERY intermittent problem with my 2013 Avalon. For the last two years in the months of Jan.- Mar. Sometimes (perhaps twice a season in Winter) When I leave the car sit for over 1 evening in a heated garage without driving it, the battery goes dead. I can charge the battery for an hour then get the car started, take it to the dealer and they can find nothing wrong. Even replaced the battery last year which solved it until the winter months set in 9 months later and now it's doing the same thing again.
I think that some accessory or something may be sticking on like the seat heaters or headlights, on those rare evenings when I don't think to check on it after I shut it off. Whatever it is, it's drawing a lot of current to deplete a new battery in 24-48 hours.

Our 2103 GS most times when you exit of the chimes going off until you close the door.
Everything is off, why it does this. I asked the dealer a while back but they gave me the "No problem found".
Again nothing is left on and it doesn't matter whether the automatic headlights are on of off.

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?

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.

I have a 2000 ford explorer sport. For some reason the battery is being drained when my wife runs errons. It will start fine and she can make a couple stops then it will be dead. Is this just because the battery won't hold much or a charge anymore? This is the original battery. I checked the cable and they looked fine. It will charge up so she can start the next morning but like I said. If she has to make a few stops it goes dead. Looking for options before I start re-building the whole thing?...

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.

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.

My friends have a 2002 Accent with the 1.6 DOHC that I've been puttering around with all weekend.
The door was left open a crack and the battery drained. It was brought in, didn't charge right (he said he accidentally put the cables on reverse). Tried to install it, still did not start, put it back on charger correctly, and then re-installed. It was unknown at the time, but the black cable that went from the negative post to the fuse box popped off, and then he said there was no lights in the car, but tried to start it anyway.
We tested the battery both with a voltmeter and at a parts store - its testing like a brand new battery. I've tested all the fuses in the box under the hood, and in the box by the driver's feet. I also tested continuity in the ground to the engine, ground to the body, ground to the fuse box, and the alternator to the fuse box cables. All the wires show up as less than 0.5 ohms resistance (I'm assuming since I didn't get an infinity reading that they are intact).
I then tried to just put the key in the 'on' position to see what I could get - no interior lights, no start, no accessories at all. It wouldn't even let me shift it with the key in. I've got no clue what left to try. I guess these don't really have a "main relay" but at any event I don't know how to properly test these relays anyhow.
This used to be my car, and last year I replaced the positive cable to the starter, and the CD player was erroring out (it kept reading that there was a CD being inserted then stopping and then turning on the radio) so I just pulled the fuse under the hood. I don't know if they would have some effect over a year after the fact.

Current issue: fuel pump stays on and has drained battery. I do know the door switch has been acting up with the usual symptoms (automatic locking at inappropriate times, lights not coming on, etc.). I know the fuel pump will often not start because of faulty door switch, but I've not heard of it causing the pump to run continuously. I haven't found much in search.

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

Where this buzzer is located? under the dash(where)? Mine doesn't seem to work anymore. I've drained my battery like 5 times already.

My daughter has a 1999 New Beetle and when she doesn't drive it for a week or so, the battery is drained down to zero and the car needs a jump start. We've replaced the battery twice - the latest battery is only about 3 months old but when we came back from a week's vacation, the car was dead. Instead of jump starting it ourselves we decided to call AAA (gotta' use the membership occasionally). They tested the battery and it was drained to zero (in warm weather). After jump starting it and a few days of normal driving, I took it to the shop where we bought the battery. They tested it and it registered 759 amps (its rated at 730).
The guy at the shop said that it was normal to for a battery to drain to zero after sitting for 7-9 days because of negative drain (keeping the clock running, etc.) I'm not sure I believe him - because I've never had that quick of a battery drain with my other cars.

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?

I've got an '05 burb that for a couple weeks now the interior lights will not come on when you open any doors. Just tonight I went to start it and it took a couple tries and finally did, but I noticed that the clock had been reset almost like the battery had been drained.
I drove it to my destination and just let it run for about 30 min thinking it needed to charge (nothing had drained it that was obvious to me). I had to go back out and it did the same thing, started hesitantly and the clock had been reset.

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?
