Prius (Gen 3) :: 12v Battery Discharged Very Often When Parked Outside In Cold Weather
I got a new Prius Plug-in 2012 and when the cold weather came this winter, which isn't that cold at 40F, the 12v battery seems to get discharged very often. This week, I must have jumpstarted the car twice already. The 12v battery seems to get drained when I park outside in the (not so) cold, or when I park underground for hours. I also notice that the traction battery gets filled up; it's as if the 12v battery drains into the traction battery.
(I leased a Prius 2010, not plug-in, for 3 years and this never happened even if I parked it for days in even colder weather.)
Prius (Gen 1) :: 2001 With Lots Of Codes - Battery Discharged
P0420 CATALYST EFF BELOW THRESHOLD
P0440 EVAP EMISSION SYSTEM
P0441 EVAP EMM SYSTEM INCORRECT PURGE FLOW
P0446 EVAP VENT CONTROL CIRCUIT
P3190
P3191
P0300 RANDOM MISFIRE
P0301 CYL 1 MISFIRE
P0304 CYL 4 MISFIRE
Was driving on highway in mild rain and car started to shudder and stalled. I ran it on the electric motor for a while to get out of traffic so it's fairly drained. Has a year old main battery and a year old 12V Optima battery. Car has 202,000 miles.
The cat code and possibly evap were on all year as check engine light has been on. I get the triangle of death with exclamation point on the right car icon on the screen as well as the check engine light. After resetting the codes the triangle hasn't come back. Haven't rechecked the other codes as it was a borrowed generic scanner.
Just checked the 12V battery at Autozone and they say it's good but discharged. Car won't start and it seems to kill the 12V battery if left to sit. I did the throttle body and MAF clean even though they both looked ok. A little oil in the intake so I mopped it up. Didn't work. I hooked up another 12V battery with jumper cables and it doesn't work. Checked the fuel pump relay and it's ok. I pulled spark plug 1 and it was fine. Check main battery and 12V connections -all fine - tight and no corrosion.
I'll try to check fuel pressure and spark.
Prius (2010-12) :: Discharged 12 Volt Battery Now Won't Have Enough Power?
We accidentally discharged the 12 volt battery in our 2010 Prius with an interior light. By the time we noticed the car didn't have enough power to turn on. I removed the battery last night and charged it with an intelligent charger and have since reinstalled.
Will this have any long term effect on the battery? It seems these 12 volts are sensitive compared to a standard car battery. I have discharged numerous 12 volt car batteries with no major long term consquences after a recharge.
Prius Plug-in 2012-15 :: Battery Apparently Discharged / No EV Range
I picked up our Prius plug in on Thursday evening, fully charged from the dealership in Oakland. We drove it home, about 4 miles, in EV mode and then plugged it in for the night. In the morning the car was fully charged. At 8:00 a.m. I drove the Prius up hill about 1.5 miles in EV mode to our car pool pick up point and left it parked on the street for the day. Car was parked on up hill slope. I believe all lights were off. When I got back at 5:30 p.m. to drive it home the battery was apparently discharged and there was no charge or EV range when I selected EV mode. I drove home on ICE in hybrid mode.

The sound emanates approximately from the area of the coolant storage tank (driver's side, behind the front bumper), though I doubt the tank or its pump is the problem. It sounds only when the car is in 'ready' status. I also think it is not one of the relays in the nearby fusebox. There water-pump drive belt is not on that side, so I don't think it's the water pump or its idler pulley. I have posted a ten-second sound recording on YouTube, greatly amplified. (Ignore the video portion.)

I went away for a week and upon returning, I couldn't get my V6 to start. I couldn't get anything to work....auto lock, headlights......and then I discovered the battery has been discharged totally. I am really shocked as how could this have happened. I have checked everything but nothing seems abnormal as I remember checking every detail before locking up the car and leaving for my trip. This is the longest time which I did not use my car. Before that the longest was less than a day. Btw, the car is only 2 months old.

I tried to turn on my car this morning, but the "Ready" sign didn't go on. The whole display is black. "Check Engine" sign blinked briefly. Battery display shows the battery is "green". Everything else works - cd/radio/bluetooth, etc. As I tried to start it, the screen showed that the engine briefly charged the Prius battery, then it was all quite. I tried to wait and restart a few times, but still the display was all black and no "ready" sign. I WAS able to still move the car, but I didn't chance to drive it out of the garage. I just had it serviced (oil/fluid change). Small battery was replaced in July.
View 19 RepliesPrius (2004-09) :: Check Engine Light And Clicking - 12v Battery Dead?
I went out in the 9 degree temp this morning to start my car and take off for work. I sat down and hit the power button and some console lights came on. The gear lights were blinking with a square light around each letter (P, D, R, B...) and the pips on the fuel gauge were blinking, beeping during each blink. Also, the green light on the power button was blinking and the little light showing that the key was not in the car was also on but the key was beside me. I turned it off to try it again.
Before I turned it back on, I inserted the key in the slot and hit the power button again and just the Check Engine light came on and everything else was black. There was a slow tempo click-click-click-click... sound coming from under the hood and the Check Engine light was just sitting there. I tried to turn the car off but the power button was not doing anything. All I could do is let the Check Engine light stay on and the click-click-click-click... sound chirp away. I went back out in a couple hours and the battery was dead.
Just seeing if that might mean something specific before I go drop about $200 on a new 12v battery later today.
Prius (2004-09) :: 2005 - Driver Side Power Window Clicking After 12V Battery Change
I have an issue with Prius 2005 driver side power window constantly making clicking sound even after turning off the Prius. All other power windows works, just the driver side is having this issue. This started happening after I changed the 12V battery for my Prius.
The window still rolls down and up but it's very slow and making even louder clicking sound while rolling down and up. Also an other thing that I noticed is that windows keep going down slowly by itself after it's been closed. Any clue as to what went wrong with my driver side power window ?

View 3 RepliesAccent LC (2000-05) :: 2004 Won't Start - Rapid Clicking Sound Comes From Under The Hood
Two weeks ago my car would not start, so I had a friend try and jump the battery. This battery wouldn't hold a charge, I took it into O'Reilly Auto Parts and they said the battery was shot. I put the new battery they recommended, the car ran fine for about 5 days. I took the battery back to O'Reilly and had them test the battery, it was too low to start the car, so they charged it and sent me on my way. The car ran fine for the rest of the day. The next morning the car would not start again, so I called the auto parts store and they recommended switching out my alternator. We switched out the alternator and the car fired right up, it ran perfectly (lights, heater, radio, etc) until yesterday.
While driving down the street, I noticed the radio head unit flicker, then it shut off. The car kept driving for about 2-3 city blocks, then all the lights shut off (dash lights, headlights, tail lights, brake lights). I turned onto a side street and the car couldn't go above 10-15 mph, it seemed. The speedometer and other gauges started going berserk, followed by a ton of dash lights coming on. The car basically rolled to a stop. I put it in park, turned the key to off and had it towed to my house. When I turn the key to accessory, all the lights work, as well as the heater and radio. But when I turn the key to start the car, a rapid-clicking sound comes from under the hood.
Prius (Gen 2) :: 2005 Stalled - Clicking Sound And White Smoke Coming From Under Hood
I have a 2005 gen 2 Prius, 106k miles. Recently in Florida, we had a heavy rainstorm, and I happened to drive it through a flash flooded road. Water was deep enough to reach my headlights. I was out within 10 seconds, then had my car towed. There was a clicking sound and white smoke (steam?) coming from under the hood. The car would start, and I could drive it if I wanted to. After talking to a mechanic, he said to let it sit for 30 minutes with the engine on. Like magic, it started to work like normal, check engine light went away.
Drove fine for 2 days, then the check engine light came back on. Had the codes read at autozone: P0103, and P0031. One day later, my car stalled out while I was driving, and the dashboard lit up like a Christmas tree. Red triangle, yellow exclamation, brake, abs, "problem" on mfd, etc. This site has saved me before, so I came on and thought it could be the MAF sensor. I cleaned it with MAF cleaner, but no luck. I order a new sensor, still no luck. My car stalls out seconds after starting it up. I cleaned my throttle body, still nothing.
Prius (2004-09) :: 2008 - Brake Creaking / Clicking Noise - Lubricating Lever / Shaft?
I have a 2008 Prius with the platinum 7 yr/100K warranty. The brakes are making a creaking/clicking noise when pressed. It only happens when the car is coming to a stop. If you start the car and sit there and press the brake pedal it doesn’t make the noise. Only when the car is in motion and coming to a stop. I took it to the dealer and they said the brake lever/shaft needs to be lubricated. It is only heard on the inside of the vehicle and doesn’t seem to affect the brake performance.
They said it would not be covered under warranty since it was a lubricating job and not a mechanical problem. They said they would have to take apart the whole dash to get to that part to lubricate it. It would be covered only if the part has failed or broken. They called Toyota to approve the fix, but it was denied. It is just annoying to hear the creaking noise every time I come to a stop. I am supposed to pick up the car tomorrow since they are replacing some other items. I asked for a parts diagram of what part needs to be lubricated to see if I can get to it. I have to take part of the dash apart to install my LockPick and XM radio.
Prius (2004-09) :: 2008 - Traction Battery Died?
I own a 2008 Prius with 87k on it. The factory hybrid warranty was good through 11/15 and on 1/22/16 the dash lit up along with the MFD screen. After research I thought it was an inverter pump. I got the call from Toyota that it was throwing a P80 code meaning it is the hybrid battery. The dealership told me that it would run 3200.00 for a new replacement. I called the service manager and had him send in a goodwill exception since we service our 7 other toyotas with them.
Toyota corporate responded they would cover the battery under goodwill but I would have to pay the labor cost of 450.00. I spoke to the service manger and the dealership is covering half of that which I'm only liable for 225.00. I'm not out 3200.00 but after doing more research the typical battery last 60-80k. Some are luckier to get over 150k. For those Prius owners approaching those miles beware that you might need a battery replacement. This will be the last hybrid I will ever own.
Prius (2004-09) :: 2008 Does Not Always Engage EV Mode When Battery Is Green
I have noticed that my 2008 Prius does not always engage EV mode (after I push the EV button) when the battery is green (nearly fully charged) and speed is well below 45 km/hr. Message displayed is "switching to EV mode is invalid now". So it seems there are factors at play other than the speed and the level of traction battery charge.
What these are? Is battery temperature monitored? Will the operation of the air conditioner affect it? Most times it doesn't but I wonder if under certain circumstances it might.
I use it at times if I am going up a slow speed incline, often from a standing start, knowing that there will be plenty of opportunity to recharge shortly after.
Weather here is pretty warm- around 30C maximum during the day.
Prius (2004-09) :: 2008 - Battery Stays Blue All The Time
My 2008 Prius battery stays blue all the time and my MPG went 43 from 51MPG. Two days ago I drove almost 600 miles but battery sign didn't go to green. I dont know if is there any problem with my car? NO CIL.
View 17 RepliesLexus RX 2004-09 :: Battery Resets When Turn Off Engine / Pop Hood
I recently replaced a dead battery in my Lexus RX 300, and have noticed something weird which I'm hoping to get an explanation for (and potentially fix).
When I turn off the engine, sometimes the battery itself seems to disconnect.When I try to turn on the car at this moment nothing happens. However, when I press the button which pops the hood in the car and then try to start the engine, everything turns on fine (and my clock resets).
My guess is that something is loose near the battery, but how to address this.
Prius (2004-09) :: 2008 - Entire Dash Lit Up Then Died - Dead Battery?
I have had my '08 Prius for 3 years and have little to no problems with it. This morning I jumped in to go to work and the entire dash lit up and then faded out and died. The only lights still on is the check engine light, Airbag light and the little green light on the Park button. The worst part is now I can not completely shut it down. I am wondering if it is just a dead battery or if this is something bigger. If it is a dead battery I am baffled at how it could be. I have AAA coming to jump it and I hope that is all it is. Sound familiar?
View 16 RepliesPrius (2004-09) :: 2008 - Hybrid System Warning Again Even After Replacing 12V Battery
I haven’t been on these boards very often since getting my used 2008 Prius because until now it has been very kind to me in terms of not needing mechanical repairs. Unfortunately that good streak seems to have come to an end. Driving home Monday evening (after ~30min freeway driving), my master system warning light came on, accompanied by the hybrid system warning light. I didn’t know what the latter was – had to look it up – but I immediately pulled to the shoulder. The car was driving normally, however. Since shops and dealers were closed for the evening, after much debate I ended up having the car towed to a family friend’s body shop; they were still there and had a scanner to check the error codes for me. My car was on the side of the freeway for well over an hour with hazard lights on and the dome light on and off occasionally as we got in and out of the car. By the time the tow truck arrived, I discovered that the 12V battery seemed dead; car wouldn’t boot up all the way, wouldn’t shift to neutral and didn’t want to power down – I had to try turning it off upwards of 10 times. I was surprised, given just the hazard light and limited dome light usage. We jumped it, got it in neutral and on the truck.
At the body shop, they said there were no error codes related to the hybrid battery; something about transmission that wasn’t clarified, and errors for low voltage on the 12V battery. With everything off, it measured 10-something V; something higher when turned on, but they believed the problem was a dead 12V battery. I was surprised that it would suddenly give out in the middle of driving, but we went ahead and replaced it the next day. I picked up the car Tues evening, and had no problems driving it home, to work the next morning. Unfortunately, during my drive home – strangely at almost exactly the same location as the first time – the same hybrid system warning light came back on. I’d driving about 70 miles with it off at this point before the reappearance. This time I didn’t pull over to the side (had enough of that before) but rather drove a few more miles to a parking lot where the car has now stayed overnight. I note that the car seemed to drive perfectly normally during that time; no loss of power.
