Prius (2004-09) :: When Does HV Battery Cooling Fan Come On
My inverter over heated. Looked at reservoir for motion of water saw none. Took car to toyota for pump recall. When I got it back I heard the pump. Never heard it before. I don't think it ever worked. & water is flowing in reservor now. Now I am thinking about the HV bat. fan because I never never ever heard it working. When does it come on and how could I test it?

I am having issues with my air conditioning on the 05 prius. For some reason when I leave to go somewhere its fine, but if I stop for long periods of the time the a/c stops cooling, the fan is still blowing. Once i take off it cools somewhat better but still not cold as it should be.
I have already had the car checked for DTCs and there are none, plus I had the a/c vacuumed down and recharged to factory specs, it still has the same problem.
Prius (2004-09) :: 2005 - Code P0A82 / Battery Cooling Fan Not Coming On
We took our 05 Prius to the mountains on Sunday. Coming down the hill from Lake Tahoe the temp climbed to 98. Suddenly we got the red triangle warning and the Hybrid system warning light. The car ran fine and showed no symptoms of any problems. We took the car to the dealer Monday morning. They Read the code P0A82. They said the Battery cooling fan was not coming on and blamed the problem on dog hair. The warning light was off. The car ran fine going home with no warnings. My questions
1) Can/did the dealer reset the warning light?
2) Is there a way to verify that code P0A82 is a bad cooling fan.
Prius (2004-09) :: 2007 With 45K Miles - Failing HV Battery?
The battery gauge on my 2007 seems to be dropping much faster than it used to. I can back out of my driveway with full green, and be down to purple in two miles of <45MPH driving. It also seems to recharge faster, as if the 'window' of usable charge has become much narrower.
I took it in for the 45K service, and asked the dealer to investigate. The tech wrote that everything is fine, and that this behavior is normal because "this is deep cycle battery".
Two questions: If the main battery fails completely, will the car still be driveable or will I be stranded at that point?
The little 12V battery is still the original that came with the car. Could it cause the above symptoms?
Prius (2004-09) :: Battery Drains In Couple Of Miles

View 5 RepliesPrius (2004-09) :: 2005 - Massive Hybrid Battery Discharge In First 2-3 Miles
My 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.
Prius (2004-09) :: 2005 - Battery Not Working - Dying Repeatedly At 120,000 Miles
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.
Prius (2004-09) :: Battery Charge Up To 8 Bars All The Time
My 05' with 130,000 miles has been acting weird lately. It likes to charge up to 8 bars all the time now. Before it was always around 5-7 bars. It goes down to purple 2 bars on a 2 mile hill climb. I see the bar from 6 going down to 3 or 2 immediately.
When I am driving on a flat road at constant speed. The battery is charging or being used continuously. Never does it stay at discharge or charge for longer than 2 seconds. The arrow goes green then orange then green, on and on and on. Besides that, it seem to drive ok. No dash lights what so ever.

Prius OEM fan control - EAA-PHEV It seems like at least in the Gen II, the battery fan is quite "lazy" and comes on way too late just like most variable speed fans in electronic equipment.
In the Gen III, does the fan have the same problem? If so, is there an easy way to perform the mod that can be easily undone?
Prius (2010-12) :: Traction Battery Cooling Fan Come On
How often should the traction battery cooling fan come on? It started to be warmer here in FL, and I hear this fan more often now. I bought my 2011 in December and up until now almost never heard this fan working. Now it comes on at least couple of times a day, mostly under heavy acceleration in Power mode.
View 6 RepliesPrius (Gen 3) :: Battery Cooling Fan Constantly Runs At Every Highway Trip
The past week I have noticed my battery cooling fan running constantly on all highway trips - 20 mile one-way trips going 65-70MPH.
The performance of the battery doesn't seem be degraded, but it seems like the battery is hopping more between charging cycle or whatever you would call it , where you watch the instantaneous MPG on the highway drop down for 10 seconds to 40-50, then back up to 60-70.
The car is a 2011 Prius III. It did not run like this earlier in the summer in the same weather conditions, I would hear the fan maybe once every few weeks in hot 90 degree weather. Now I hear it constantly. This is my first summer owning the Prius so this may be normal, but I wanted to double check with you all if this is a sign of premature traction battery death or something.
Prius (Gen 2) :: Hybrid Battery Cooling Fan Running Constantly With Lots Of Warning Lights
Some years back my "farm" '05 prius when a host of bells and whistles went off, cooling fan ran more than normal, and I lost power a couple of times. Turned out this farm prius had an accumulation of dirt, dog hair, hay and other debris that needed to be cleaned out. You got me through the whole process, and the car's run fine until.... . Fast forward a couple of years to 200,003 miles. Now the cooling fan is running pretty constantly, the red triangle stays lit, the check engine light comes on, the (!) is on, and the VSC light is on. Haven't hooked it up to check codes, but did check cooling fan and it's clean. Would it possibly possibly better to change the 12 volt battery?

Now when I got home I went to sleep. I got up 7 hours later and went to go check on my car. It was locked as I always leave it and the keys were not in the ignition. But there was a distinct electronic sound coming from the battery. Like a small motor running. It was odd.
