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?
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 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 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?
A yellow triangle with exclamation mark illuminated on my dash. Pg 3-100 of the manual has a picture of the light, and the description calls it the "master warning light" and continues: "This indicator light illuminates When there is a malfunction on the low washer, Smart cruise control, and so on. To identify the details of the warning, look at the LCD display." Later in the manual there are examples of the light going off together with LCD messages, so I know that's what this light is called.
There is no message on my LCD display. When I first bought the car, I set the car to remind me at 5000 miles about getting my oil changed (I drive mostly highway, long trips etc.) For the last week, the car's LCD has been reminding me that i'm due for service in X miles. Today, I hit 5000 and the messages stopped. Around 5050 miles on the clock, the yellow triangle warning light went off, with no explanation on the LCD.
Bluelink diagnostics also reports no errors. Is it just the oil change interval that I set and passed?
The airbag warning light came on last week and stayed on for my hour commute home. Later on that same evening, I took the car out again, and the light was off. Stayed off for about 3 or 4 days and now comes on intermittently. I called the dealership today to try and set something up, and they said if if it's coming on intermittently, check under the seat for anything obstructing the airbag sensor and whatnot. I looked today and found nothing (I keep my car extremely clean) but none the less found no issue. The service advisor from the dealership also said that I need not bring it in unless the light stays on all the time. But I'm insisting on bringing it in in the next few days. I'm just concerned that either the airbags may inflate without cause, or may not inflate in the event of an accident. Should I wait until the light stays on? Going into the service department at my local dealer is always at least a 2 hour ordeal and they don't issue loaner vehicles unless they absolutely have to. I just don't want to waste my time.
View 20 RepliesVery occasionally and usually from a cold start I get a rapid discharge of the battery.
View 7 Replies2006 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.
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.

View 10 RepliesI have been using ACC a lot during my daily commute, it's really an effortless way to drive the car on a daily basis.
One of the issues I have been running into with it is that sometimes when the car in front (recognized by radar) accelerates and immediately decelerates to a quick stop my Sonata's ACC does not react and apply the brakes fast enough. The car will basically apply some braking power (~50%) while very quickly approaching the car in front, all the while triggering the rapid beeping of the Collision Detection system. Everytime this happens I have always had to manually intervene and apply the necessary braking power to stop short of hitting the car in front. This is pretty ridiculous to me since if the car KNOWS that it will crash without additional braking, and has the ability to apply the brakes, why doesn't it do so properly?
On my limited sometimes when I am driving randomly and a car is in front of me but not far up my collision warning signal goes off.
It's only happened about 4-5 times and I am not sure what sets it off or how it even really works?
Have any of you noticed the collision warning popping up on the dash while driving? The first couple of times I missed what was popping up since I was busy driving and not getting into a collision. The last time, however, I did notice. A car was making a right turn up ahead and had almost stopped in the lane..
View 17 RepliesExperienced an incredible failure this morning when I went out to start my 2015 2.0t Ultimate. Foot on brake, press start. Engine starts and the car icon in the middle of the instruments shows the system scan. Scan completes and all warning lights stay on. The LCD panel starts to report system after system has failed ... SCC, EPB, FCW, RPD, LDW, a veritable alphabet soup of abbreviations. Put car in gear and pulled out of space to see if that would have any effect. Turning wheel very heavy as if power steering has failed. No effect from moving a few feet. Couldn't get back directly to my parking spot so carefully around the block to get back to my space. Rear view camera came on when in Reverse but it remained on after shifting into Drive.
Back into park. Turned off engine. Tried to restart. No dice, won't even go through the start cycle. just all the warning lights on and LDW Failure on the LCD panel. Arranged a tow to the dealer and when the tow truck arrived we discovered the Electronic Parking Brake had automatically engaged even though I intentionally had left it off and there was no way to release it. Battery appears to have plenty of power so unlikely it is a low battery issue ... the two times it did start it turned over without hesitation. It's behaving as if the computer has been totally scrambled. There used to be a joke around that if Microsoft made cars, all the instruments and warning lights would be replaced by a single big red light in the middle of the dash reading "General Vehicle Fault" and it seems like that's what mine is telling me.
This 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 RepliesOn my way home tonight, I received several messages on the screen that a battery drain is happening and I should start the car. However, it WAS running!
View 12 RepliesMy 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 just noticed this morning that the "warning" light (orange triangle with exclamation point) is on in the Multi Info Display in the middle of the dash ONLY when the engine is off. I scrolled to it and it says "check charging system" with the battery logo. When i turn the engine on, the warning light goes away.
The battery logo does not light up where the gauges are. Does this mean the battery is okay? Its confusing and the manual does not clear it up.
Am I correct in assuming that I'm low on battery only if the battery logo lights up where the gauges are? I have no issues when starting the engine or anything.
There is what appears to be an icon on my touch display that resembles the battery icon on my smart phone. Currently is has one red bar lit up. I have not been able to find anywhere in the owners manual what this battery icon means and what to do when it is red.
