Lexus RX 2010-15 :: Traction Battery Cooling Fan Running Consistently
We're on our 3rd hybrid. Our new RX450h traction battery cooling fan under the back seat seems to run consistently after the car is driven for a few minutes. Our previous Prius and CT200h did not exhibit this. Is this typical of the 450h?

My hybrid battery is shot and I do plan on rebuilding it when I can afford the cells. I was talking with Mike at xvipers.com yesterday and he said he could disable the hybrid system and make it run on the engine only for $40. He also says it will get 27mpg that way which is not bad. How one could do this?

Recently installed a curt trailer light. I modified the V plug in harness to work with the C.
I noticed the fan was running louder then usual. I took the right rear panel off were the HV exhaust vent it and there is no ducting from the factory.
The battery duct just goes to the back of the seat and vents out in that right corner right behind the 12V.
It makes its way up and over the right rear tire tub then what ever comes out of the rear exhaust, just vents out with momentum from down below. No duct guiding it from what I can see?
I went back and zip tied a wire that was in the path to sides were other factory wiring runs.
This seemed to fix the issue after making everything neat?
Not sure what caused it but it seems to be from wiring that was in the way? When I run the HV fan with my SG and remove the shock tower assess cover on the passenger side. I can feel hot air coming out. This might be an easy way to get more exhaust venting for anyone that wishes to do that.
Prius (2010-12) :: Can Use Traction Battery To Jump Start / 12v Battery Dead?
If my traction battery has plenty of 'juice' in it, and my 12v battery is dead....is there any way to 'jump' the 12 volt battery with the traction battery to get the car started?

This is my first year driving my prius during a hot season, and for past 3 weeks my mpg has dropped from 49 to 41-43 mpg, and the reason is my traction battery keeps getting HOT! I can hear the battery cooling fan turning on constantly at max when i reach 20 mph, my car doesn't want to start in EV mode the engine just kicks in no matter how light you press the throttle, the EV motor is not assisting with the engine, the infamous slow rpm drop keep occurring and I when to touch the traction battery case and it its HOT, Ive open up the case to check for any dust on the fan and ducts but so far its spotless. I really wished they place an AC vent for the battery because the back passenger area with full A/C doesn't t get as cold as the front dose which doesn't cool off the battery.

Purchased a second traction battery and installed it in parallel with the existing battery? Perhaps one from a wrecked Prius.
I'm thinking that would double the Ev range, which would be very handy in my current commute due to long term construction on one of the highways I use. I am in sub-5 mph stop and go so long each day that I wear down my battery and the ice ends up running while stopped, thus killing my hypermiler goals.
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.

My prius is almost 5 years old and has 88K Klm (49K Miles) My battery has gone down to one bar of late. This never happened until recently, never went below two. The bars seem to fluctuate up and down much quicker than before. My mileage is slightly down but it could be because of other reasons. Does it seem that there is something wrong with the battery? No warning lights are coming on

So I have searched about engine rattle/knock and I have found lots of results for cold starts but I haven't found it for the issue that I am having. I have a 2010 and anytime the battery is real low, around 2 bars and the ICE fires up to charge it, any time I give it a little throttle input, I get heavy valve rattling. It doesn't matter if its cold or hot, it does it as long as the battery is low. I never get this noise when battery is charged up, only when low. I have a link to the video below and you can see once I give it some input, it starts to sound like an old diesel tractor. Prius has close to 200K on the odometer and all my maintenance is up to date. Please turn the speakers up but the noise is right at 5 seconds in or so.

I have had my 2010 Prius 2010 for a year now. I have been taking my Prius to a full service car wash with the conveyor belt. They have always seemed ver Prius savvy. But the last couple of times, after getting in the car and driving away, the car seemed to hesitate upon initial acceleration. Then the problem goes away.
The last time I took it to this car wash, I sat in the car, because I only needed the express exterior wash. About a third of the way through, the instrument panel said "Low Traction Battery... put into Park" I did not obey the warning because I was afraid of putting it in Park while the conveyor belt system was pushing my Prius along. So I ignored it. By the end of the car wash, the engine had shut down. I had to start it up and drive out, and I got that same momentary, initial hesitation as I accelerated, like before. The hesitation went away after that.
Prius (2010-12) :: How Long Does Traction Or Hybrid Battery Hold A Charge
I've noticed that after sitting over night my battery for the hybrid system is not charged enough to operate the car in EV or for the first mile or two it does not seem to use as much electric power to supplement the car. After a couple miles it is charged or near charged and I see more use.
View 5 RepliesPrius (2010-12) Fuel :: Charge Traction Battery While Stopped In Hot Weather?
On a hot sunny day, occasionally I have to be stopped for extended periods with the A/C running which means the engine will come on for a few minutes out of every 10 minutes or so. to charge the traction battery. Engine comes on at 2 bars and goes off at 3 bars.
As engine efficiency at idle is low, would it be better to put it in D with the brake firmly pressed and push the accelerator so that the engine speed is in the high efficiency range so as to produce more charge for the fuel burnt and maybe also I could charge it to a few more bars on the battery indicator?
Prius (2010-12) :: Yellow Triangle With Message - Low Traction Battery Shift Into P Position
Today after running several errands, I stopped by the local CarWash to rinse the car. Same as always, parking brake off, shift into neutral and away we go. Half way threw she starts beeping, I see the yellow triangle and to the right a boxed message "LOW TRACTION BATTERY SHIFT INTO P POSITION". There was a sudden rush of anxiety because I could not shift while being conveyor-ed threw the wash. As soon as I was pushed out and the light turned green, I shifted into drive to exit. The warning and box cleared instantly.
I pulled into parking, shifted into P, and noticed the battery indicator had only 1 bar. Did a quick walk around of the car and got back on the road thinking, head directly the Dealership. Before I got to the freeway I was back up 4 bars and climbing. Continued on the freeway and within 2 exits all looked normal. As it is Saturday and the Dealership was 1 hour from closing, I proceeded home. Later we went to dinner and an event, then came home. All is still normal. Owners Manual only states to follow the command on page 515.
I know this is a long story and was intentional to starve off multiple questions. The only thing I can think is that the air conditioner, radio and headlights were on prior to, while waiting my turn for wash (park-roll-park-roll...) and up to the point of the warning (tuned off all at that point) while in the tunnel. However this is normal for me. Will monitor the battery indicator more closely for a while. I'm sure this event latched in a computer somewhere, so will run by the Dealer if anything else acts up again. A/C and radio and lights are turned off now while in "neutral", for whatever reason. The car is a 2010 II and only 27600 miles. Was not a pleasant feeling.
Elantra MD (2010-15) :: Turning Traction Control Off Under Normal Dry Conditions?
I was just thinking about this last night when driving home under heavy rain. It was nice to have it on the highway turns where there was heavy flooding and hydroplane possibilities, especially since I am used to 4 wheel drive in these conditions. I was wondering if I shouldn't be turning it off under normal conditions though? I know it's handy to do so if you are stuck in heavy snow but since the default is always on I wonder if there is any other gain to only using it when needed rather than only turning it off when needed?

My girlfriend has a 2010 prius with the navigation package. We go to the drive in movies quite frequently because it's cheaper and close to us. Every 30-45 minutes the prius will automatically shut off the battery. The interior lights turn on and the sound goes off.
We are kind of getting tired of getting dirty looks when this happens. So we're wondering if there is a way to take this setting off.
Prius (2010-12) :: Engine Keeps Running When Battery Cold?
up. Coolant temperature was high (160 F). Car was in low speed (5-10 mph because of traffic). Battery level was high (67.8% 7 pips).
But gas engine was still running non-stop.
Checked battery temperature. It was 28 F.
Switched from recirculating to fresh air mode. The battery temp raised from 28 F to around above 32 F rather quickly. Then the gas engine stopped and car started to run on full EV mode.
Did not know the fresh air mode will have such a prominent effect on battery temp...
Will use more fresh air mode in summer when the AC is blasting.
Prius V :: Traction Battery Gauge Never Shown Full Battery
My 2012 Prius v has a traction battery gauge beside the fuel gauge. The gauge has never shown that the battery is full. It appears as if the indicator is 2 bars below full at all times. Is this by design or should the gauge look full with bars to the very top after charging on a long trip?
