Prius (2010-12) :: Battery Drained For No Apparent Reason
Dec 15, 2010
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 2010 Model I with only 19K miles on it (purchased new). For the past year or so, at any time throughout the night it will give out 5 beeps for apparently no reason. I have reset the system by disconnecting the alternate battery and have used a PocketScan Plus to test the systems which shows no problems.

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 own a 2003 BMW 5301 with the sports ,premium and 'M' package. Of late the battery drains for no apparent reason. This happened a few times 2 months ago and I had the battery and alternator replaced. This has again started happening. The car starts promptly in the morning but refuses to start in the evening when I am ready to leave work. It has to be jump started. This does not happen everyday and the BMW service folks have not been able to figure this out.

I just recently purchased a 1996 celica GT Hatchback. It had 263K on 235K the timing belt was changed, oil and filter, tire rotation. When I bought the car on the 13 of August it drove and ran well. Drove it home over 45 miles with no issues. Only issue I noticed was that third gear grinded a bit but it's to be expected. Today after it had sat for all that time with the lights on the battery was dead. Jumped the car. cleaned and protected the contacts on the batt. and hooked it all back up. Let it charge for an hour and then drove it to work. On my way to work the engine oil light came on and the car died on my. It has oil and there are no apparent oil leaks. The car is turning over but not starting.

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?

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?

There is roughly 800 on the odometer and I was averaging around 35 mpg. I filled it up and driving home afterwards I noticed the mpg drop off significantly. Now I'm lucky to get get 27. It was as low as 16 on the trip computer. The range was the same and the miles come off in sync with the odometer. I'm wondering if its a glitch with the trip computer?

2014 Elantra GLS ... Upon closing, and just as it reaches the wind defector, the Sunroof will " kick back" no apparent reason. This may happen once, twice in a row or not at all. I have checked the sunroof path and the wind defector, but no obstructions are visible.

I have a 2001 Suburban (chevy) 5.3 liter Vortec engine, auto trans 4 wheel drive, fully loaded. As of late I come out in the morning to find a dead battery. this happened before and I disconnected the fuse for the dvd player that was installed aftermarket. some times I have to hit my dashboard to get the dash lights to work, now they dont work at all. sometimes the ride control compressor runs for no apparent reason when the car is off. I replaced the battery 3 years ago and it seemed to solve the problem until now. I replaced the battery with an optima red top yesterday and now the electrical system is going haywire. the ABS light is flashing and the service ride control light is on, the fuel gauge is bouncing back and forth from full to empty. What should I do. I am a fair mechanic but electrical is not my forte.

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.

A month ago my check engine light came on so, after checking to ensure the gas cap was screwed on correctly, I did what the manual recommended and took my car directly to the dealership. After paying a diagnostics fee and losing my car for an entire day while they ran tests and contacted Toyota, my dealership told me they couldn't find a problem and just reset the indicator.
Within a few days the light came on again but before I had a chance to take it back to the dealership it went off. Now some 3 weeks later it is on again and I'm wondering what to do.

I have noticed a significant (15 to 20%) drop-off in mpg in the last 6 months or so. My 2006 prius at 95,000 miles is just short of the warranty on the battery pack. I brought it into the dealership and they ran the routine computer diagnostics and said everything looks good. I fully expected them to tell me that the performance on the battery pack had fallen off, so I was a bit put out. The guy actually got a bit defensive with me when I asked him some further questions about what the criteria are for determining whether the battery back was performing as it is supposed to in order to get the maximum MPGs.

I just had the ICE start on me for no apparent reason. I was driving down Santa Monica Blvd this afternoon. I was accelerating very lightly on a slight down hill and the ICE came on. I looked at the dash and it showed I was in EV and less than 1/3 the way to the power portion so that rules out accelerating too hard. At the time my speed was around 30mph. Temperature was 70 degrees so no heat or AC. The battery was at about 50%.
The only thing I can think of is that it came on because I hadn't run the ICE in a very long time. My trip B indicated that I had done 114.7 miles since the last time the ICE fired up. That's about 184 kilometers but I know that it is supposed to fire at 200 kilometers (about 124 miles). ICE firing up earlier than 200 kilometers?

I just took advantage of incentives and traded in my 2012 PiP for a 2015. In hilly San Francisco I'm accustomed to between 8 and 9 all-electric miles per full charge. Today was the new PiP's maiden voyage--a six-mile trip that in the old car would leave me with 2.1 to 2.3 EV miles remaining (per the readout.) But the new car actually ran out of electric power just before the trip's conclusion.

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.

I have an 07 Camry and the alarm keeps going off for no apparent reason. Is there anyway to reset the alarm system itself? If so how and what do I need to do? How to do this.

I tried starting my car today and it didn't want to go. I took out the air intake sensor blew at it and plugged it back in and started it, but it didn't sound the same, the muffler wasn't making as much noise as usual and just sounded like the engine wasn't working the same. After that it started normal and i've been driving for about a week, and today it didn't want to start again so i took out the censor did the same but still didn't start so i put down the clutch revved it a couple times and like magic it worked.
I think i need to change the censor but i'm not sure and i don't want to spend money if i don't have to.

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?
