About 20 minutes ago I started up the car and the screen indicated the main battery was pretty much empty. And hour before I had pulled into my driveway and the battery had indicated maybe 70%+. The car was off, nothing like headlights or anything I know of was left on.

leave the car parked for 4 days and when it starts it shows one bar below full green.
put the car in D and go to the corner about 1/4 mile, maybe less and its down to one purple bar then starts to recharge . AC/RADIO ECT ARE OFF
2006 Prius with 130k miles. I'm thinking that my HV battery has slowly deteriorated to the point where it's causing drivability issues, and now needs to be replaced.
The main symptoms I'm experiencing are rapid charge/discharge according to the MFD and significant loss of power once the battery has discharged to one bar. I realize the latter is "normal," but the problem is that I'm seeing one bar frequently now. Hill climbs that my car used to do with no problem and would drain the SOC to 2-3 bars now cause the battery to drain to 1 bar about half-way up and then loss of speed from 65 mph to 45 mph by the time I reach the top. Descending hills, it's not unusual to see the SOC go from 2 bars to 7-8 bars within 30 seconds or so.
I'm not seeing any error lights, and my (cheap) code reader does not report any logged DTCs.
This seems to be a slow degradation of battery performance, rather than an outright failure. I first noticed that the battery would charge/discharge a little quicker than it had been at about 90k miles. At 99k (before the warranty ended) I took it into the dealer and they tested the HV battery. Block voltages ranged from 16.59 to 16.68 V and resistances ranged from 0.025 to 0.026 ohms. Based on this, they said that the battery was fine, and sent me on my way. Since then, the problem has just gotten worse and worse, though.
My car is an 05 and currently has 219,000 miles. Runs great. Only things I've replaced are the 12 volt battery and the rack and pinion. Replaced the rack because I was trying to drift in the snow and tried to beat the traction control. Needless to say, I lost and hit the curb. Jammed the gear in the left side of the rack. Replaced the rack with a $75 used one and no problems since.
My issue is this, even if my battery is at 6 bars when I first take off, my hybrid battery drains down to even as low as 1 bar. It only got down to 1 once but is hitting 2 regularly. After about 3-10 miles it is back to the regular charge rate. I also noticed the other day with the window down, there was a slight whirring sound, almost like a gear or wheel that is a gummed up and is being slowed down. It also felt like there was resistance, almost like the brake was dragging. After a few miles, as in less than 5, the noise was gone and the car was going along just fine. I've checked the emergency brake to see if it's dragging by applying it and releasing it several times. Does not appear to be the issue. Today I put it in neutral to see if that changed anything but it did like it always does and just coasted along fine with no resistance. My thought is the transmission. I'm wondering if the fluid it so old and broken down that maybe things are gumming up. Either way, I purchased the tranny fluid and will change that out. I know people will probably gasp but I have never changed it. Actually thought because it's a cvt and there is no dipstick to check it, that it doesn't need changed. After reading up yesterday I discovered I was mistaken.
I think that's about it. I'll edit it if I think of something more. Once the battery is back up to charge it accelerates and drives like normal. I do want the car to last so my daughter can use it when I buy the new Prius Prime.
I have a 2005 with 165K on it. Just within the last 2 weeks, at start up, no matter what level the charge shows on the display, the HV battery will almost fully discharge and then come back up to full charge within a mile of driving. I just replaced the 12V battery thinking this could have been an issue, but it didn't change anything. The car never acted like this since I bought it in 05. When it drops to the discharge level, It running on ICE only, with the typical slower acceleration. What could be going on?
View 8 RepliesVery occasionally and usually from a cold start I get a rapid discharge of the battery.
View 7 RepliesThis evening, long after sundown, I found myself stuck on an unmoving expressway with no sign of traffic starting up again (the radio reported a vehicle fire ahead, all lanes blocked). Time dragged on, and I started worrying about the possibility of the headlights draining the 12V battery , assuming that they do indeed run off the 12V battery. In a conventional car this wouldn't have been a problem because the idling engine would have maintained enough battery charge, but of course here the ICE wasn't running. So I turned off the power button to shut down the lights (it's a Canadian car, so there's no way of turning off the headlights with the power button on). That was safe in this particular situation because there were plenty of stopped vehicles behind me. It definitely would not have been safe if mine had been the last vehicle in the lineup.
View 7 RepliesI still have my 2004 Prius which currently has 264,xxx miles. The car runs very well (at least I think it does). I have always maintained it beyond what was required. Anyway, it has been very, very hot lately in south Florida (high 90's plus 50% humidity) so I do not know if that has anything to do with my problem. I have noticed that after I have driven the car for a while the engine periodically turns itself on when I am at a stoplight even though the battery shows practically full (full blue). The engine will continue to stay on until I resume driving. I have the AC on full blast as it is needed to keep the cabin cool. Otherwise, the car seems to be performing satisfactorily.
View 7 RepliesI have posted separately about my 'supposed' dead HV dead battery. The charge was down to one bar and the the system didn't allow ICE to start for recharge. I finally got a reading of a about 207 volts today and when I fiddled with the start button on and off a few time today, the ICE started. After about 15 sec.
It indicated it was pumping juice into the battery. When it finally got up to about 4 bars it turned off. I had to move the car off the tow dolly (it's home for the past week) and did so in electric mode even though there was a Ready on the display the engine never came on. Before maneuvering it around much I tried to get the ICE to start again to recharge the battery, now down to 2 bars.
By pressing the gas in park and neutral, it would start and rev up but never generated any power to the battery. Fiddled around with the power button some on/off/on, etc. until I got the ready light and sometimes it would start charging but only once did it charge to 6 bars and usually stopped as soon as there were 4 bars.
When battery is low (purple bars IN DISPLAY) EV mode is not allowed, obviously; but WHY is it not allowed when the battery is full or nearly full (green bars on display) ?
View 6 RepliesMy 2012 Prius v has a traction battery gauge beside the fuel gauge. The gauge has never shown that the battery is full. It appears as if the indicator is 2 bars below full at all times. Is this by design or should the gauge look full with bars to the very top after charging on a long trip?
View 5 RepliesMy car is eating up battery power: only when outside is cold, below 10 C,something very strange, in summer days there is no battery draining, my climate stays adjusted at 19 C, but now is very cold and I make it 25 C,and then it is the mystery: the battery is draining for 2-3 hours below 10V?
I made some tricks:
-when the car i turned off while climate is set to 25C(or above 24C)-the battery is draining very fast, second battery relay switches on and I can turn the ignition on only with the key in!
-when the car is turned off while the climate is set to 18C(or below 24C) the battery drain is very small???
So does something turn on while the car is locked,or something is trying to keep any temperature inside? I double checked if AUX heating is off,and it is off,I don't have parking heater or anything. Another thing I notice is when I turn on the rear seats climatronic above 24C the voltmeter goes from 14V to 13V and stays there for a 5-10 min,if I turn off the rear seats climatronic or set it below 24V the voltmeter gets back to 14V?
Whats is happening with the car?
The stereo will power off after 10mins or so (even if the ignition button is on ACC or Power position), and the radio screen shows a battery discharge warning (this goes on before the power gets cut off).
Is there a way to keep the stereo power on even with the engine off? The ignition button is already on ACC or Power (without engine on) and the system still cuts off the power after 10mins or so...
I got the Battery discharge warning massage today, I was listening to xm in the car for about 5 minutes on engine set to ACC and the Battery discharge warning massage came on and tells me to run system while the engine is running. Am I not suppose to be on ACC if I just want to listen to music?
View 17 RepliesI just brought home a shinny new 2012 Hyundai Sonata Limited with Nav and it's awesome! Just discovered something though...
When the engin is off and I am running the radio I get the Battery Discharge Warning pop up on the Nav screen accompanied by a beep. It goes off every minute or so.
This is going to be annoying next time I go to the drive in that we like to frequent as we need to play the audio on the FM radio with the car turned off.
How I can turn this off or disable the sounds at least?
I replaced a post-cat O2 sensor because of a code that came up last week. We didn't reset the ECU, but after driving it a couple days the check engine light went out. 3-4 days of driving and everything looked good.
Today the check engine light came on again and autozone read the code as:
P0136 - heated oxygen sensor - bank 1 sensor 2 (HO2S12) sensor range/performance condition
Explanation Open circuit or short circuit condition
Probable Cause
Poor electrical connection
check other service codes
Faulty Bank 1 Sensor 2.
Anyway, I thought it might be because we didn't reset ECU and some kind of calibration might be off in the system. So, I unplugged the battery in an attempt to let it discharge and reset ECU. When I connected the battery back up.... ALL THE FREAKIN LIGHTS ARE NOW ON THE DASH. Check engine... traction control.... tire pressure.... everything.

I've noticed that the display shows the Battery Discharge warning while the vehicle is running. I notice it while reversing, because - well, I'm watching the image from the camera. The message goes away in a few seconds and the regular "look around you" advice appears. It doesn't happen every time nor does it follow a change in weather. Just random occurrences.
View 10 RepliesWhy the battery indicator on my v is never full? It's always one bar less...
How is everyone's battery indicator, have you ever get it to fully charged?
I've had my C a week and a half and it is doing great, but I wonder if the system is ok. It has never shown the battery at 100%. My Civic would charge all the way quite often.
View 19 RepliesI notice that if I use AC, the battery drains a lot faster. If i do not use AC, I see my battery stays at one bar from full on flat freeways or local streets.
If I use AC, I see the battery goes down quickly to 2 bar from full just on local streets.
So AC drains the battery quite a bit. Does ppl use their AC all the time or not?
I never see my battery full or empty. Why? There are always 1 or 2 levels missing or left, and it can't go any further.
