Prius Plug-in 2012-15 :: EV Mileage Sudden Drop

I was driving up a hill today at about 30 mph with .9 miles remaining showing on my EV battery meter when all of a sudden it drops to 0 EV miles remaining and shows only 2 of the battery level bars (which is very very low), and the engine of course turns on. What happened?

I promise I did not push the EV power bar over its threshold. I monitor that like a hawk. I also know for a fact that it jumped from .9 to 0, because I watch that part like a hawk. This part of the trip is near the end of my drive home and I've done it about 50 times so far with no issues. With .9 miles left at that point on the hill I have always been able to make it to my driveway with .4 or .5 remaining, so this is very odd.

Prius Plug-in 2012-15 :: PHV Range Could Increase Mileage Without Using EV Mode?

I'm just curious...if somebody drives a PHV Prius like a regular Prius (not using the 13 mile pure EV mode range), could they theoretically get better gas mileage by staying in the electric part of the hybrid system indicator?

Prius Plug-in 2012-15 :: AC Use Subsequently Increase Estimated EV Range?

Typically after I use AC for most of the available battery capacity in EV mode, then following a charge, estimated EV range typically drifts higher.

Prius Plug-in 2012-15 :: Estimated Range Has Dropped After Fill Ups?

I have noticed that my estimated range after fill ups has dropped after the last three fill ups. I used to get around 520 miles after fill up. The last three have been in the 480 miles range.

Prius Plug-in 2012-15 :: How Accurate Is The Estimated Miles Left In Tank

I was wondering how accurate the estimated miles in the tank is? For the next two days I will have a 204 mile commute. The Prius estimates I have 210 miles left. Should I be able to make it?

Prius Plug-in 2012-15 :: ECO Icon Always Lights Up When Driving In EV Mode And Car Switches Over To HV Mode

I have noticed that when driving in EV mode when the car switches over to HV mode the Eco icon always lights up! Of course you can select Eco, or Power mode manually, but when it does this automatically, after the EV battery charge is used up, it keeps showing the Eco icon being lite not HV.

Prius Plug-in 2012-15 :: EV Mileage Range Down To 9.8 From 12.4

My Plugin is only about 4 months old, but the EV mileage range is now down to 9.8 from 12.4 from the first very first day I charged it overnight. This with HVAC and fan off.

Prius Plug-in 2012-15 :: 2004 - Mileage Per Tank

My 2004 has 132K miles and still running great. We now have a PIP standard model as well. I can't find a screen that tells what the overall mileage per tank is. Does it exist on this car?

Prius Plug-in 2012-15 :: 2014 - Mileage From 45 - 46 Normal?

Brand new 2014 Prius Plug in. I am getting about 45 mpg on a 14-mile all-city trip and 46 mpg on a 30-mile mixed hwy/city trip. The mpg numbers are from the information display when the car were turned off.

Is that normal? I thought it's supposed to be about 50 mpg. Btw, ECO mode was enabled.

Prius Plug-in 2012-15 :: Mileage Is Off - Check Engine Light Comes On

My son got this for his '05 Prius, and I plugged it into my PiP for awhile. I am learning to brake more slowly and accelerate more gradually, but the mileage is obviously way off. That seems to be about all it's good for, unless a check engine light comes on.

Prius Plug-in 2012-15 :: EV Mileage Dropped Without Any Apparent Reason

I just took advantage of incentives and traded in my 2012 PiP for a 2015. In hilly San Francisco I'm accustomed to between 8 and 9 all-electric miles per full charge. Today was the new PiP's maiden voyage--a six-mile trip that in the old car would leave me with 2.1 to 2.3 EV miles remaining (per the readout.) But the new car actually ran out of electric power just before the trip's conclusion.

Prius Plug-in 2012-15 :: Engine Start Resetting Mileage Back To Zero

I have a vague memory that the PiP will start its petrol engine every XXX miles just for a maintenance warm up if it has not been used for that mileage. An engine start will reset that mileage back to zero and start recounting its EV miles until that limit is reached again. What is that limit?

Prius Plug-in 2012-15 :: EV Mode And Using A/C?

Can you drive in EV mode with the A/C or heater running to keep you cool in summer and warm in winter? If so, how much does it change the range from the normal 13-14 miles of EV?

I'm trying to determine how short of a commute I would need to have to not use gas while still driving normally and not giving up climate control use.

Prius Plug-in 2012-15 :: Cold Weather Driving (Rattling Noises) - Gas Mileage Down

Today, I experienced the coldest temperatures yet on my drive to work. At one point, I saw a '24F' shown as the outside temperature (although not unusual for April in Minnesota):

Expected: My gas mileage was down a bit. I was impressed it wasn't as bad as I would have expected from our 2005 Prius, though.

I should have expected: On the last 1/2 mile or so, when driving slow on the little bit of EV left while in the forced HV mode, I accidentally accelerated too much and forced on the ICE again (it had been previously on earlier in my 22 mile commute). This time, however, it was different because it didn't shut off immediately. I think the ICE had to do a second warm up. I'll have to watch that more closely next time (darn that cold weather)!

Prius Plug-in 2012-15 :: Car Goes Out Of EV Mode When One Surpasses 65 Mph

On a long downhill, with EV mode selected, the car goes out of EV mode when one surpasses 65. When slowing down from 70, the car will not go into EV mode until one is down to 62. THen it stays there until one exceeds 65. I wonder if there is any difference in what is happening when one is going downhill at 66 vs 61? Both are using 0 gas. But one counts as an EV mile and the other does not. Here in high Colorado, this sort of thing makes the EV ratio somewhat meaningless.

Prius Plug-in 2012-15 :: Gas Engine Often Starts In EV Mode

On occasion - not frequently - I'll notice the gasoline engine kicking in when I'm in ECO/EV mode with plenty of EV battery left. Today it happened on a relatively flat street, going maybe 30 mph, without the a/c or anything else on, and about 7 miles left on the EV battery indicator. In less than 30 seconds it went back to pure EV and the gasoline engine never kicked in again.

Prius Plug-in 2012-15 :: Blended HV Mode At All Speeds

Today I drove my Prius Plug-in from my home almost to the highway in EV mode. When about one minute from the highway, I pushed the PWR mode button twice, on and off, and the ice came on for warmup. All the green symbols above the speedometer were cleared. I then again pressed ECO to bring back that mode.

I believe the vehicle was in what I think of as blended HV mode. This mode blends the extra battery capacity of the Plug in with the ICE. After a 40 mile trip, the available EV miles dropped from 13.9 to 1.2, and the trip meter registered 76 MPG. I went up and down a serious hill which probably reduced the mileage.

Prius Plug-in 2012-15 :: Difference Between EV And Early HV Mode?

Is there a difference between full EV mode and the early HV mode where you are in EV (left half of the indicator on the HSI screen)? Aren't you in full electric in both situations? If so, then why would you need to manually toggle between the two modes?
