Prius (2010-12) :: Won't Start - New Key Fob Battery?
Jul 22, 2016
2012 Prius
Got home from driving. Then 15 minutes later went out to the car to head out again. Car would not start or recognize key fob. One of the two.
Headed back to my computer and researched how to charge key fob. Went back into car, pressed down brake and held key up to start button. Have done a lot of variations of this. The light with the key and car on it was flashing periodically.
Got new battery entirely for fob, installed and still could not start car. Tried the key charging again. Still nothing. At one point I was able to turn the radio on but the display did not come on for the car itself, just the radio and sound.

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?

Not like when you leave the dome light on overnight. I mean when the 12v battery has reached the end of it's useful life after 5-6yrs. How do you know it's time? What will my Prius actually DO? I ask because,in this -10 weather we've been having, my truck wouldn't start. It did that "old, dead battery thing" we're all familiar with. Got me to wondering about how my Prius will act.

The 12V battery must have been drained completely over the weekend. None of the lights (interior and exterior) are working. The car won't start even using jumper cable. I guess the 12v battery must have some juice remaining to power up the computer in order to jump start the engine. Am I correct in this assumption?
My Prius is only a little over three years. What is the warranty on the 12v battery? I read that the OE battery is not the best. How long would I expect the OE 12v battery to last?

Just bought a 2010 Hertz GenIII w/44,000mi. Wife had trouble starting it twice with weird messages like place car on flat surface to orange triangle. I hear it may be a weak battery???

Friday I went to pick my daughter up from the school. Turned 2010 Rav4 off while waiting on her and then attempted to turn back on. I have a smart key, so it is just a matter of pushing the button, but nothing. Band teacher attempted jump starting it with no results. Next day my husband purchased a new battery from AutoZone and we installed it. Have lights, etc. now but it still won't start. tried putting the key up to the on off switch to get it to start, still nothing. It doesn't even sound like the car is even attempting to turn over.
There are multiple lights on in the dash, the check engine light, oil pressure light, electric power steering light, and the automatic transmission fluid temp light. I just had my car into the dealer to have the oil changed, tires, rotated, and the 25 pt. inspection done on it. Upon raising my hood the other night, I noticed that the reservoir for the radiator was empty. It should have been full, as I just had it into the dealership, so where did it go. Should I add coolant to it. Is there something that needs to be done after changing the battery?

I have a RX350 2012 model. Recently, in last 3 weeks my battery has discharged 3-4 times, I had to call for a jump start.
I got my battery checked with my dealership and they say the reports from battery are excellent!
I am not sure why is it discharging? I just think there might be a sensor failure which is keeping something running in my car.

Is the Optima D51 battery the best buy for my 2010 Prius and do I need the installation kit too? Is that kit only available from Eleanaid?

I own 7 taxi's 5 of them are 2nd generation and 2 of them are 2010's . I have had a couple 2008's that had over 600,000km before they were written off in accidents and the origional battery was still working fine. They certainly were not 100% but still were running ok.
I just ordered a hybrid battery for my 2010 that has 280,000km. Very disappointed. Another taxi broker with our company has 3 2010's and he has replaced the battery in 2 of them.
I talked to a mechanic at Toyota and he says the battery is getting too hot because there is not as good of venting to keep it cool as the 2nd generation has. The 20 hour + days and the battery being so hot compared to the 2nd generation is to hard on the battery.
The 2010's have all had transaxle problems and the 2nd generation never had any work done on the transaxle which was amazing the way we eat transmissions in out taxi's.

I noticed it literally when pulling off the lot when I bought it. I only hear it when the car is in drive or reverse, only when gas engine is not running. It is a specific pitch hum. It stops when I hit the brake, and begins again as soon as I take my foot off the brake pedal, only when transmission is in gear. My 2010 Prius II doesn't make this noise.

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.

I've noticed that if I press the EV button when stopped at a stop sign or red light, I can get the vehicle moving up to 25 MPH with the battery. This must save fuel. But I wonder if I am doing something that causes problems with the battery, motor, or other systems.

I am in the market for a used Gen III regular Prius. I know that battery in Gen III is smaller in size and weight, so energy density is greater. That's great. But I wonder if you've seen high mileage (>200K) Gen III owners experience battery performance deterioration, like someone experienced in Gen II.
My 2004 with 220K miles only get 44mpg in this summer temp. (I drive it a little bit aggressive, use AC, and don't care much about hypermilling) I think at least partly it is due to weaker HV Battery. I can clearly feel that now it is easier for engine to rev very hard when accelerate at 50 mph. That's not the case before.

It seems like the fan that cools the hybrid battery pack turns on quite often, almost everyday after two or three hours of driving. I heard it once or twice on my '05, but on this one I hear it pretty much everyday.

I was just wondering... I am in the navy so i'm called to go away quite often sometimes for extended periods.
I have read that the 12V battery will discharge itself if it the car is not being used frequently because it has the memory for everything (radio channels, time, trip meters, etc)
My question is how long is it safe for me to just leave the car parked in my driveway without disconnecting anything and when should i disconnect it?

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.

So the 2011 Prius was sitting around for a month as my friend was out of town. It is parked in my side yard. The hybrid system started just fine, and I put it in neutral while I was sitting there about to drive it. The battery shut off while in Neutral. From what I've read, the battery won't charge while in Neutral. The car will not accept a jump from another car using jumper cables, but it IS GETTING POWER from the portable 10amp charger I set up. The lights in the cabin now come on, the doors respond to the key, etc. The engine will not start though, even though the battery charger says "fully charged". As soon as I unplug it, there is no power to the Prius. I think the problem is that there is no way to get it into "P", which according to the manual, is the only way to start the engine.
The hybrid system will not start in Neutral, according to the manual. How to get it into "P" at this point? The light just doesn't come on when I hit the "P" button. I've tried simultaneously holding the Power button, trying to switch "mode" and everything. Nothing responds.

When the shaded area is in the battery half of the ECO bar I would expect to have the mpg be 100. It sometimes shows only 25 mpg. Just purchased a 2010 and learning how to get the best mileage possible.
