Prius (2004-09) :: 2005 - Dashboard Lit Up And Battery Fan Kicked On - Mpg Dropped To 35mph
Jul 28, 2014
My 2005 Prius started showing all the symptoms of a dead/dying hv battery this morning. The dashboard lit up, the battery fan kicked on and my mpg dropped to 35mph. I was half way to work, so I just continued. I have been checking around and I can get it replaced for about $1000.00 reconditioned, but they have a 7-10 day waiting list. The dealership wants $3500.00 minimum, and says that I should not drive it at all and have it towed. Is this true? Can I drive on gas alone until I find a solution?

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 am pretty new to Toyota Prius. Today I went to test drive a jap import 2nd Gen 1.5 Prius with 50k miles. What I found weird with the car was that, on the startup the petrol engine also started and it was on for the duration I was driving. I then turned on the EV mode and the petrol engine turned off but looking at the battery capacity on the screen, the battery drained pretty quickly possibly (2-3 minutes) and the petrol engine kicked in. Is this normal for 2nd gen prius cars ?

I just bought 05 prius from a dealer I don't know the history was told all it needed was a hybrid battery.
Now I have a 05 that I drive with known good parts so I pulled my hybrid battery and installed it in the new car the monitor showed engine charging inverter then going to the battery. However the bars on the battery graph start dropping. only code is a engine code 2102.
I also noticed the old A/C condenser in the back.

So I met my wife after work. I was killing some time with my son. We drove across the street, then to a neighboring shopping center. I changed the display to see the more accurate instant MPG and noticed my battery was at 2 bars. This is the first time that's happened, that I'm aware of. During normal operation, it stays at 2 bars above the halfway mark, or above.

I recently got my 2007 Prius back from the body shop after a 13k repair following a crash that crumpled my front end. The car seemed to be doing fine, until a long, steep climb had the battery drop to one bar, speed dropping to 40 despite a floored accelerator, and a red triangle that appeared briefly before disappearing just as we completed the climb. It's the dropping speed despite a floored accelerator and the warning light that have me worried.

Today I went to the national car test (passed. but), when the car has been returned to me by the employee of national car test center I noticed one bar on the SOC. This happened for the first time.
Additional notes:
1) recently (about 4 weeks ago) I had to temporarily replace for second hand (20 bucks) 12v small auxiliary battery.
2) recently (withing last four weeks) I noticed high temperature in the boot compartment, I tried to investigate and the ducting leading from the HV battery was really hot, which means that my battery was really hot too.
I tried to explain this to myself that this might be due to HV operating at higher levels due to unknown state of the replaced 12v small aux battery (second hand product).
3) Today I noticed that technician at the test center used some spring assisted bar to press the brake on the car while he tested the car, I recon that maybe he have had powered off the car while doing so, is it possible that this might have contributed to the dropped SOC ?- it's just my guess.
I'm thinking to replace 12v aux battery to brand new battery and then test the operation of the fan and whether the temperature still rise. - is it good idea? Or should I just seek for the testing tool to determine the status of each of the modules?
If so, which testing device can handle this task? I heard from this forum about ELM obd bluetooth adapter. I use android device, would this be okay or should I look for another device perhaps scangauge?

I recently started up a modest hill in the snow. My '05 Prius started to lose traction and the ABS/VSC kicked in and killed the drive power. The drive then came back on and then off several times before quitting completely. The surface was slick. If I could have disabled the system, I could have driven through the situation. Is it possible to turn the system off?

I have a 2005 prius and I got a scanguage to read the codes. I have two lights on my dash. One is the check engine and the other is the (O) light. I think this is something to do with the regen braking. Anyways when I run the scanguage it says no codes found. What type of scanner would be able to pull up all prius codes?

My daughter dropped a dime into the battery exhaust grill (the vents on either side of the back seat).
Do I need to fish it out before the fan kicks in or is there some kind of grill/filter down there?

I have a 2005 Prius that I bought about 1 year ago that has about 75k miles. According to the display, I have been getting about 5.5l/100km (~43mpg) up until I did some maintenance in July.
A friend changed the oil, oil filter, and cabin air filter. Also, right around this time I bought a new set of tires. For some stupid reason, I had the idea that it had run flat tires, so that's what I bought & by the time I realized my mistake, it was too late.

I have a 2005 Prius that I purchased in 2010 as the second owner. When I first got it, I would average 50-65 MPG depending on city vs. interstate (per trip computer). After about a year, I was usually in the 40's. However, in the past 6 months or so, the MPG has dipped drastically. Based on the trip computer, I average about 30 MPG on the interstate and 15-20 MPG in the city. I have read that often times, a dip in MPG signals a need to change the 12V. I tested the 12V, and it's usually around 12.4V after sitting unused for 12+ hours.
More info: -The poor MPG is consistent whether it's 95, 65, or 35 degrees outside.
-Flat terrain (Washington, DC)
-Usually shorter trips of about 20-25 minutes.
-75% city, 25% highway. Highway driving is pretty smooth, little traffic, average of 55 MPH. City driving is incredibly stop and go due to traffic, constant stop signs and red lights, etc., with probably an average of 15 MPH when I'm actually driving.
-No overfilled oil.
-Had an alignment maybe 8 months ago - nothing unusual about the drive or tire wear.
-Goodyear Viva 2 Tire P185/65R15, maybe 15k miles put on them. Tire pressure unknown at the moment.
-I drive like a grandma in D mode.
-I don't warm up the ICE.
-HVAC is off.
-In terms of whether any significant changes occurred around time I noticed the drop: none. I was living in Florida at the time, doing a highway commute of about 2 hours roundtrip every day with a small bit of city driving when the mileage drop occurred. I have since relocated to DC, and the problem is the same.

My mechanic installed a new Hybrid battery in my 2005 Pruis using the repair manual and a video that showed him how to do it. He also replaced the harness and the ECU battery. When he tries to start the car all of the lights light up on the dash but no ready light on the start button and the car will not start. The instructions did not say anything about this issue so he is lost! He thinks the smart key and the ECU have to be synced in some way but doesn't know how to do it.

195k miles.... I have charged the battery, I have bought a new battery, I have Charged the new battery... All with no avail.. Slowly but surely one at a time the abs trac control and stability control lights come on and eventually the triangle of death... Meaning when I shut it off its not going to restart.. If i drive it sparingly it might take a week if i drive it all day then it takes one day... when fully charged there is no warning or sign that there is a battery issue or draining untill the voltage is starting to get low. I have an ultra gauge hooked up and shows 14.14 while driving, I am lost as to whats the issue. also no codes or pending codes... I have taken the new battery to auto zone and had a functional test done.. said checked good... signed befuddled

The MFD on my 2005 prius shows that every time the gas engine kicks in, it trys to charge the batt. even when it doesn't need to be charged. This has been happening for about 2 weeks, and not one time has the gas engine kicked in without showing the arrow going to the electric motor, even when the batt is completely full. I know it's not just a problem with the MFD because my MPG average has clearly gone down since this started.

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.

My Prius has 150k miles on it. We didn't drive it for a few days and when we went to turn it on,it wouldn't work. We were able to jump start it a couple of times, however after that we ended up having to replace the battery. We purchased it brand new from toyota. Then, the car wouldn't do a thing (No sounds, no lights, other than the red amber power button and the flashing check engine light, which was not on before.) We ended up having two blown fuses and we replaced them today, one was for the battery.Now the lights are on, but the car still won't start. It will cost over $200 to have the car towed and I am really trying to avoid that right now. I don't know much at ALL about cars. but I'm trying.

My 2005 prius will not start. We had some body work done to it after a deer ran into me. They did a small amount of welding and had disconnected both batteries. Now the car will not start. It can be put in auxiliary mode but if you try to start it with your foot on the brake, it flashes some lights for a few seconds and then goes dead. Is the hybrid battery too low to start the car? It was pretty low. before the batteries were disconnected. Or did they possibly do something wrong when they disconnected the hybrid battery? Final question would be do they have to do some reprogramming after disconnecting the hybrid battery?

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.

If this has been posted before feel free to remove. I searched everywhere and didn't see exactly what I experienced with our Prius when the 12v battery was in it's final stages of death so I wanted to share.
Below issues all occurred within a one week time period 3-7-16 to 3-14-16. 2005 Prius with 145k miles, replaced traction battery on 7-30-15 / 127k miles.
First occurrence - happened a few seconds after starting and driving the vehicle. The ABS light came on and the power steering faded out and then came back, just briefly, and the car did not die. Turned the car off and back on again and all was well.
I performed the 12v battery test by entering maintenance mode. (hold the display button and turn the lights on/off three times, vehicle signal check, battery check) the battery was reading 11.9volts with the car off, I drove the car and it was charging at around 14.7volts and then was reading 12.2 with the car off after driving it. Which at the time seemed a little weak but nothing that was a red flag. I've read that you're supposed to replace the 12 volt battery every 4 years but I swear the one I removed looked stock.
Second time - again happened just a few seconds after starting the car and driving. ABS light came on, red triangle of death light, brake light, power steering was gone, and the power steering light came on, the car did not die. Restart fixed the issues again.
Third time - Happened about 30 minutes in to the trip while the wife was driving on the interstate around 75mph, wipers were on due to rain but visibly lost power, radio came on and off, all the lights on the dash (warning lights included) flickered on and off, power steering was gone, car died completely and would not restart. Tow driver had to boost the battery long enough to put the car in neutral so we could load it on to the tow truck. When we got the car home the battery was completely dead again.
I ordered an Optima Battery 8171-767 (DS46B24R) YellowTop Prius Battery from Amazon which appears to be a direct replacement, and simple to install. I drove the car for a few miles, returned to the house, performed battery test again via maintenance mode and the battery was charging at 14.0 and reading 12.5 when off. I can't be certain but I think the battery check feature may be displaying false information if the battery has dead cells and the car is trying to charge the battery? I took the old battery to Advanced Auto Parts and had them run a diagnostic check and the tester stated that the battery had dead cells and needed to be replaced. I gave them the old battery even though I didn't buy the new one from them and got a 10.00 store credit, unexpected and nice.

I replaced the hybrid battery in my 2005 Prius today & when I disconnected the 12v battery the wrench arced & I assume that I blew a fuse. I have looked, but have not found anything. I hope I am missing something obvious.
