Prius (2004-09) :: Check Engine Light Came On - Hybrid Battery Dying?
Jan 25, 2012
So this morning when i started up my car the cel came on. The car seems to be running fine so i decided id try to go to work and hope for the best. Well nothing happened and i made it to work fine, but i noticed i was always regenerating power. My drive is 45 miles all freeway and little traffic most the drive.. ive never had this happen on my drive to work and ive had the car for a year now. Could the hybrid battery be dying? i have a cheap scan tool but that doesnt mean i will get the correct reading...

I just switched out my hybrid battery and put in a brand new one. Now, the car isn't doing anything and all that's on is the check engine light. What now? I was told I had to tow it to Toyota and have them reset the computer. Sound right?

My check engine light came on, I took the car to my usual mechanic, and he said the codes returned indicated that two cells in the batter were bad. (I just called to get the codes, but he's out of the office for about 30 minutes on a test drive...)

I own a 2005 prius. It is stock and i recently had the check engine light pop up as well as "problem" when car was started and 2 lights with exclamation point, one on a car and ones in lil brackets. I believe it is called a "hybrid malfunction light". Well one day they all pop up and about 3 days later theyre gone. Only thing i did was fill up the tank, when they came on only 1 bar was left on the tank. My question is should i still take it in to see whats wrong with it? and what could of caused both lights to come on?

Possible hybrid battery failure in my 2004 Prius (96K miles).
Sunday before last, the check engine light, warning triangle, and hybrid warning light came on when I started my car at the grocery store.
Because I was close to home, I drove home and the car functioned completely normally. The next morning, when I started the car, the same warning lights appeared. However, when I tried starting my car with the headlights off (I always leave them on), no warning lights appeared.
I took my car to an independent mechanic. This is their written report:
"Found multiple check engine codes, P3000, sub code 123, V0100 sub code 211/330. These codes are set when high voltage control detects a malfunction in battery pack/ECU assembly. To check battery pack we took vehicle out on a test drive while monitoring the cells in the battery pack. Found that they are all weak and drop fast when battery is put under a load. Code C2318 is a low voltage error/power supply malfunction code with the auxiliary battery. The voltage spec for setting the code is 9.3 volts, this battery is less than 9.2 volts."
In conversation, the mechanic also told me there was significant voltage variation across the cells in the hybrid battery.
I then took my car to the dealer to try to confirm this analysis. They were unable to read any codes because the independent shop apparently cleared them. The dealer was unable/unwilling to do more than read the codes to diagnose the problem. (Indeed, they seemed surprised that the independent mechanic could monitor the cells in the pack.) All they did was to drive the car around some more to see if the check engine light would come on. It did not.
The car has been driven 80 miles since the warning lights last appeared and appears to be behaving normally. From your perspective, does the report from the independent mechanic make sense and is it believable? And is their test under load definitive of a hybrid battery problem? Could the results be affected by the low auxiliary battery? Also, if I do have a hybrid battery problem, what are the chances of being suddenly thrown into limp mode while driving it?

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.

I've been using my prius 2008 very smoothly till today. It was 100F+ in Austin and very hot. The car, suddenly lit up all the warning lights: Engine, Red Exclamation, Hybrid, and brake lights. The brakes kept beeping on both sides. I also heard an engine noise that is quite uncommon for prius. I stopped the car in a parking lot.
I came back in an hour and tried to start the car. I only saw 2 lights now: Red Exclamation, and Engine check. It might some "click" noise when I started, and after that it was fine. I drove for a while and everything was fine but the 2 warning lights were still on. I tried starting and stopping few times. I did experience the clicks (1-2) and the engine noise. The engine noise lasted 15-30 seconds and then it was back to normal.
I followed the youtube video to look up the diagnostics (Display pressed + lights on/off 3 times) to check the 12V battery. It read 13.8 V. I recently had an oil change at Toyota dealership less than 500 miles back. So I am baffled at this point. I have about ~60K miles and it's a 2008 model. So if it's a hybrid battery issue, I am covered.

I have a problem with my 2002 prius. I was driving home from work when all of a sudden my Hybrid Warning light came on with the check engine light on. On the screen, it gives me a (PS, Battery, and ! ) and the "!" was the one lighting up. The engine was roughing up sounds like it was gonna stop itself so I pulled over to the side and it turned off by itself without me doing anything except to put it on park. Then, i took out my keys and tried restarting it and all i heard was the "Ready" beep but not the engine and it won't move when i step on the pedal. After waiting for 10 mins., i tried restarting it and it worked i drove away and got home safely with all the warning lights i mentioned earlier still on. (Note: i was driving w/ the A/C on because it was hot outside..around 90s, also it was not overheating nor it was any battery problem because all the electrical were working properly.)

The engine check light is ON this morning. It said that there are problems for the hybrid system on the display. I sent it to dealer immediately.

Gen3 Prius. Once it turned 100k miles I took it in for an inverter coolant change per the maintenance schedule. The dealer charged $109 for this and the car had absolutely no issues prior. Got the coolant changed on 7/23 and then drove it short distances in town for two weeks with no issues. Once I drove it on weekend longer road trip got a check engine light P0A93 "inverter A cooling system performance". Shortly there after started getting hybrid overheat alerts and pulled over to let it cool.
I checked the inverter coolant reservoir and it was still above full. After letting things cool, I turned it back on and listened to the water pump. Seemed to be running fine, heard it clearly with my ear up to a long screw driver, touching the pump. Noticed that the hose leading to the pump was vibrating but the return hose out of the inverted was not. Also no turbulence in the reservoir. My guess is that they didn't bleed air out of the system.

I have a Honda Accord 2004 Hybrid with 85,000 miles on it. My IMA and check engine light went on less than 2 months ago, and the dealer replaced the starter battery and it was "fixed". Less than 2 months later the same thing happened and the dealer claims that the hybrid battery is failing, need to replace it, and they can't do this anyhow because the part is backordered "indefinitely". Honda extended the hybrid battery to 80,000 miles but you are over the limit. So here's my question:
1. Can the car be driven without the hybrid battery, just using gas engine, without risk of getting stuck somewhere?
2. Is there any other remedy that would be less costly?
3. Was this a known problem that I should have been warned about when I bought the car.

Trying to figure out whether to fix or scrap our 2005 Prius with 193,000 miles and a mysterious 12V battery problem. What would you do in my situation?
We've had a recurring problem with the 12V accessory battery: I have replaced it myself three times. The last failure was the most mysterious, because after replacing the 12V battery for the third time, I conducted nearly daily voltage tests using the Prius' "secret" vehicle signal check. Voltage coming off of the 12V was normal, if not high the entire time in all of the Prius's various starting and ready modes. I wired up a solar panel to trickle-charge the 12V battery when we weren't around, and we plugged the 12V in at night to a trickle charger to keep the battery topped up.
Nonetheless the day came a few months after the latest replacement when we had our usual 12V failure symptoms: the time on the clock started resetting, the car didn't turn on on the first press, the Prius computer rebooted, and eventually the car wouldn't start without a jump start. This has been super-frustrating, and googling around, I haven't been impressed by people's reported experiences trying to have the dealer try to resolve such problems. My worry is that a dealer repair person will change the accessory 12V battery without fixing the underlying problem. I would suspect a parasitic draw somewhere, but voltage tests when the car was overnighted without any kind of charging did not suggest a serious voltage draw on the 12V battery.
Other details about the car: our keyless entry hasn't worked for several years (dead batteries in the key fob?) and we open the car manually using the key each time. We stick the fob in the slot each time we want to start it. MPG is comparatively low vs. other Priuses, perhaps 44-45 MPG, and lower when the 12V battery starts to die (37-40). I have had the car serviced (oil, etc.) like clockwork every three months; recently, I've noticed the engine is starting to burn oil a bit (level is reported low on each change).
Most of the driving has been done in the flats and the heat of California's Central Valley, and we've put something like 120,000 miles on it just in the last five years. Besides the fact that the 12V battery keeps dying, the car has been very reliable.
We just inherited a free Prius with just 60,000 miles on it, and I have a 1993 Camry with 150k miles on the chassis and maybe 60k miles on the replacement engine I had dropped into it a few years ago. The Camry just passed California's smog test and seems to be running well. We don't want or need three cars.
Our choice is to try to fix the Prius with 193k miles on it and donate the Camry (which gets about 20 miles to the gallon, the horror...), or keep the Camry and donate the Prius. My instinct is to not drop thousands of dollars into the high-mileage Prius, especially if these issues might be pointing to a dying main battery.

So I went to start the car (2013 C3) and it wouldn't start. The batter was horribly dead (dim screen and would only go into POWER ON mode.) I charged the battery for like a half hour using a plug in charger using the hood terminals. When I tried to turn it on later, The only thing that came on was the check engine light (really dim) so it's not charged up enough yet obviously. The issue is now it won't turn off. That check engine light is still there. No other screens are on and the vehicle doesn't make any other noises (door ajar, etc.)

My 2002 Toyota Prius keeps dying (triangle of death and OBD Code 3191) after running smoothly for a few seconds each time I start the engine. Clearing the DTC code allows restart. But the check engine light and triangle of death keep returning after a few seconds.
It has been doing all this since I recharged the 12V battery (which had been drained completely by a dome light left on for 3 days). Initial attempts to recharge the 12V battery were causing current spikes at charger, and (relay?) clicking sound under the hood. So I disconnected positive battery cable and charged the battery in isolation, then reconnected it to the vehicle after charging was complete.
When I reconnected the recharged 12V battery the vehicle (honking horn) alarm went off. But that stopped when I unlocked door with key. It may not be related, but I'm also hearing a fan-like sound (under driver seat) when ignition key is in run position. I don't recall hearing that sound in the past.

Jumped into the Prius this morning to discover dash lights working, no radio etc so vehicle would not turn on. Replaced the auxiliary battery (about 5 years old.) Now all dash light, radio etc are looking great BUT:
- Enngine will not engage
- Message stating Check Hybrid System
- Various waning lights on dash (yellow waning triangle, swerve icon on left)(battery, brake, chech engine, steering wheel?) and abs!!!on the right)

I only drive my car once a month or so to visit family. A few years ago my 12v Battery stopped working in my car. I assume age and just moving my car from one side to the other every morning contributed to this. I got the battery replaced at my local Toyota dealership in Jan 2012.
In early March of this year my 12v battery died again. I jump started my car every morning (with a portable battery pack) until I was ready to drive it a distance a few weeks later. I got about 2 miles and then my check engine light came on as well as my Hybrid System Warning Light.

My 2010 Prius sat idle, parked for 7 days while my wife and I were on vacation. When we went to pick up the car, the airport valet said that the Prius wouldn't start, and so that they'd have to jump it. I approved the jumpstart, and got into the car. We got about 1/4 a mile before the display totally freaked out, including the "check hybrid system" as well as about every warning light there is. The car was beeping, acceleration was lost and it eventually died on the side of the road. The car would not start back up.
Had it towed to the nearest dealership. Initial diag from the service manager was that the 12v battery was dead. I approved replacement of that, and also authorized clearing out "a few software alerts". Got a call later in the day from the same manager (very nice guy) and there are about 11 errors that cannot be cleared out. Now he's asking for 3-4 hours labor to "trace the wiring" as suggested by Toyota. Apparently the tech had been in touch with them all day.

I have a 2002 prius with 143,000 miles. On Friday, I went to start my car and put it in gear and the check engine light came on and the "triangle of death" lit up and car died. I turned it off and waited about 30 seconds and tried starting it again. It started and I drove 1/2mile home. Went into the garage and got the Actron/OBDII code reader. Pulled the code P3125 which when I googled it, it was referring to the inverter. I cleared the code and all was well.
