Prius (2004-09) :: Battery Fan Remains On / Warning Light Came On
Aug 11, 2014
I just purchased a 2006 Prius with 89k miles and it has a problem with the drive train and randomly losing all power on the freeway causing me to make emergency shoulder stops to reset the car.
The symptoms are as follows:
-red triangle on, orange circle with ! on, check engine light on, hybrid monitor green car symbol is red with ! in it
-traction battery fan is always on when car is powered
-the car has never driven under electric power
-shifting problems, sluggish acceleration and all power loss on freeway
-hybrid monitor system lies and shows the battery full one second and empty the next.

My 12v battery died, I tried recharging it etc, but it was dead so I took it to my local Toyota dealer and had the battery replaced.
Because I had the battery off, there was a VSC warning light, which I thought that the Toyota dealer could reset. They re-calibrated all the warning apart from one, they say that the Yaw sensor will not clear it's warning and needs to be replaced.
if I can reset this warning myself, or do I really need to replace this sensor?

I have an 07 and replaced the HV battery. Before swapping battery, I had Red Triangle, (!), VSC, Check Engine (took car to dealer who diagnosed it as needing HV battery). Now new battery is in but error-icons remain. The LCD display shows battery as more that half-charged. I connected an old Actron ODB2 scanner (circa 2000), but it doesn't Read any codes and doesn't Erase the codes causing the problem.

In my one-owner purchased-new 2005 Prius w/ 74K miles and w/ no maintenance/accident history other than doing all scheduled maintenances at Toyota Dealers along w/ recalls applicable at each time (other than we had Toyota replace the 12V battery last year just because I knew it would die at some point anyway and I don't like pushing my luck; I'm not 100% certain if there's been a recall on any water pump for this car and if so, don't believe the dealer has mentioned it), I have the following indicators which appeared all at once while I was driving along at around 45 MPH in no unusual circumstances (80F, dry afternoon, about 30 minutes into a trip of mixed speeds, no loads in the vehicle, no effect on the car while driving):
From Left to Right on the display:
1) Red Triangle - Master Warning Light
2) Orange (Symbol)CHECK - Malfunction Indicator Lamp
3) Orange (!) - Brake Warning Light (but it didn't highlight the word 'Brake' in red)
4) Orange VSC - Vehicle Stability Control Warning Light
On the Screen:
Orange Car w/ the ! symbol - Hybrid System Warning Light
We immediately aimed for the house (about 5 miles away); the car drove perfectly fine, with the engine stopping and starting at lights as needed, with speeds going from the 55MPH we were traveling at the time of the alarms down to 0 and back up thru 35/45 MPH and such per normal off-interstate driving. The battery currently shows all the blue bars, and the engine and hybrid systems showed charge/discharge as usual as we drove. There was no discernible change in the driving reaction of the car to brake, steering, accelerator, etc.

A warning light has come on stating" Key battery low". How do I fix this?

But while driving the hybrid warning light turned on in the MTD. A red car if I remember correctly. It was the hybrid battery over heating and to try and mess with the wiring going to the cooling fan in the right rear quarter panel.

2005 Prius I picked up a few weeks ago decided to eat both of it's batteries for lunch and leave me high and dry. I replaced the aux battery yesterday which I was lucky to get at cost at the toyota dealer since the aux battery was original. Put it in and all was well with the car for the rest of the day. Got in it today and headed out and was welcomed with the big stupid "!" triangle, the regen brake warning, check engine light, "PROBLEM" written on the display with a picture of a "!" inside a car outline, and some severely reduced performance. So I looked online and found a place with a bunch of low mileage batteries out of smashed up 2009's.

First a little background on the car , it has 217,000 miles. The battery was just replaced with a used one. While taking it through the carwash, she put it in neutral and a minute or two later she got a warning that the battery was not charging and to put it in gear. Sounds like the battery is having issues to me. She has a 60-day warranty.

I have a 2007 Prius. We left for vacation for 2 weeks. Came home. Started the car and then all the lights came home. I thought the battery must have drained. But the lights are all on with a new battery. Is there a way to clear all these?

My 2006, with original 12V battery, finally failed to start. It was stone dead. I've been expecting this for awhile, given the age of the battery, but so far it has exhibited no warning symptoms. It was just stone dead in the garage, having not been used for five days.
I used my jump box, which I keep in the back of the Prius. Everything fired up without a hitch, other than the alarm going off when I applied power (rather loud with my head under the hood.)

I've seen lots of posts about the traction battery regarding cooling fan speeds, sensors, overheating, under charged, but is there a dash light that warns the batteries are overheating before they are damaged ? I'm worried about someone riding in the back of the car, covering the vent and causing battery damage. It is hard to see if they are covering the vents when you are sitting in the front driver seat.

My 2007 Prius suddenly lost power and all lights on the dash board light up. I had a "problem" error as well. Eventually a message came up stating there was a transmission P lock mechanism problem.
Long story short, realized the 12volt was dead and replaced it. However, the car is still not running after replacing the battery. It went once around the block fine, and then the same thing happened with all the lights (check engine, VSC, brake system, and !) and P lock mechanism warning. Disconnected the battery for 15 minutes and tried again. No luck.

A year and a half ago, I had the hybrid battery warning lights come on and had it towed to the dealer. After given the option of replacing the battery for $4300, I took it home and did a single cell replacement (all cells ~8V, one at 6.6V which I replaced), which seemed to be all good until yesterday. Back with the warning lights and blower fan, I jumped to the conclusion that I have a similar situation, removed the battery and all cells are 8.04V +/- .05V except for 1 cell at 7.92. I am not convinced that this cell is really the culprit.

2006 Toyota Prius 93000 miles
On 3/8/13 my Prius would not start. I read some information online and came to the conclusion I needed a new battery.
I started the car, and it immediately started up. I drove it for a very short time and parked it in the garage.
Today I started the car and drove it for about 5 minutes to a restaurant. I did some shopping and about 3 hours later I started the car and A Big Red Triangle appeared along with a yellow circle with an exclamation point in the center and the check engine light.
I immediately drove it to the Toyota Dealer 5 blocks away.

I've had my 2006 Prius since Jan. Today it started giving me a warning when I put it into drive. The warning was the battery couldn't charge while it was in neutral. It told me to place it in park. I did. I repeatedly tried and even drove out of my parking but it continued to say this with the ! in the triangle appearing. I've never even put it in neutral before.

I had noticed a drop in MPG in the last month (more than normal this time of year), so I started searching on PC. That lead me to testing my 12V battery 4 days ago, with the following results:
No load: 11.8V
Load: 11.5V
Charge: 14.2V
Car started and ran fine, but since the battery is the original on my 2006 with just under 130,000 miles on it, I figured I'd get a new 12V the next time there was a good deal at Advance Auto. No other symptoms until today. After driving around 150 miles on Saturday, the car sat for 3-1/2 days in 25-40 degree temperatures. Started and ran fine today. Did a 5 mile trip, followed by a 1/2 mile trip, followed by a 5 mile trip home.
On the way home, the car lit up like a Christmas tree (appropriate for this time of year). Master warning light, brake system light (yellow; not red), check engine light, VSC light, hybrid system light (no ABS light). Turned it off and restarted and the VSC wasn't lit, but everything else still was.
More info... I finally got around to disabling the back-up beep, and the driver side seat belt warning yesterday, which may have run the 12V down even more.

I've seen this a couple times but always made it home with the Red Triangle and VSC warning. A year ago, I blamed it on the OEM 12 volt battery and eventually replaced it with a Optima Yellow Top. No more problem until today. Day time driving with my Plug-in Supply 10k rechargeable conversion performing normally. City driving raining but normal Western WA conditions. Red Triangle and VSC warning. Other systems operating normal.
I knew, from previous experience that the Prius operating systems would continue to work only until I turned it off. I did turn off the Plug-in Supply controller to isolate that system and observed that the OEM traction battery was at a fairly high state of charge and the ICE was still providing the normal amount of assist to the traction battery through normal street and driving conditions.
I should have driven the 20 + miles to get home, even with the Red Triangle warning. I had done that in the past with the old OEM 12v battery. But I needed gas and went to a station and turned off the system ICE out of habit. Sure enough, the system wouldn't go back into Ready but would go from Park to Neutral. Since it was rain hard now, and I was calling my road service, I ask for a Flat Deck Tow home rather than a jump start.
As soon as I got off the tow truck I put my battery charger on the Yellow Top and it only read 11.7 volts. It's still on charge now. Now I'm wondering why the power conversion system wasn't charging the 12 volt battery or is my 1 year old Optima bad?? Or is there something about my driving conditions/plug-in conversion that is effecting the charge of this battery. I did a 2400 mile road trip to So. Calif and back to WA without any problems. Car has just 98169 miles right now. About 10k miles on the Plug-in Supply conversion.

Well all the lights are on for mine as well as of 2 days ago... checked the 12v, was at 11.8v, tested under accessories load (without engine on) and went to 11.4v then tested with the car on and we're at 14.2v
So just to be safe I went ahead and got a NEW 12v and installed it yesterday. All the lights went away immediately. Drove 30 minutes to the town over after the install... fine.... it sat off for about 1 hour.... drove it back home another 30... perfectly fine.
This morning the wife takes it to work, starts the car, all the lights on again... turns it off completely, then turns it back on and all the lights are off and then drove it to work just fine.

I have a 2003 Prius with just over 116,000 miles. When my wife cranked it a couple of days ago, the "Hybrid System Warning Light" came on.
As advised by the owner's manual, we didn't drive the car. We took it to the local dealership to be checked out. When I called for an update last night, they said that the computer indicates that the hybrid battery is leaking.
So I guess my questions are:
1) What kind of lifespan is typical of a 1st Gen Prius?
2) How many more miles are reasonable to expect from the gas engine?
3) Is there anything I should be aware of to make sure I'm not taken advantage of? (eg is there a credit for the battery since it has valuable components)

I have a 2004 Saab 9-3. Currently the Battery Warning Light has come on. It came on while the car was being driven. The car's performance seemed to suffer and it was hard to turn the steering wheel. We were about two miles away from home and we somehow managed to get home but we simply couldn't get the car to turn on to our driveway because of loss of power for steering.
We checked the Saab manual and it reads : Warning Charging - This light comes on together with 'triangle/exclamation' light if the battery is not charging. If it comes on while you are driving, stop the car as soon as possible and switch off the engine.Check the alternator drive belt. If the belt has broken, the engine may overheat (cooling system will not function properly), the battery will not be charged, the A/C compressor will not run and power assistance for steering will be lost.
Our observation:- We experienced the a/c not working too well- We had problem with steering - It was almost as if the steering wheel was locked. It was extremely hard to turn. Is this an alternator belt or a battery issue? If so, how do we figure out?

I bought a 2006 Prius with a diagnosed bad battery and tons of warning lights lit on the dash. Toyota had diagnosed a bad hybrid batt and ECU. (I have not replaced the ECU). The car was driving and running fine otherwise.
