Prius Plug-in 2012-15 :: Miles To Empty Failing When Driving In EV Mode With ICE Off?
Feb 28, 2014
As I was trying to use up as much E10 before refueling with E0 I was watching the miles to empty and noticed what seems strange, to me. When driving in EV mode, with the ICE off the miles to empty kept falling! Apparently miles to empty somehow includes EV miles. So I checked the MTE both before and after charging and saw no change which indicates EV miles don't count. So now I would like to know what does MTE mean?

I have had my PIP for just about one month now and I have only filled up twice. This car is awesome! I noticed when I filled up the last few times that the last block on the fuel gauge started blinking and my miles to empty reading was pretty low. However, when I filled up the tank, it only took around 9,2 gallons. Doesn't this car have a 10.6 gallon tank?

When in EV mode, there are times that I approach a hill where I want to be in pure HV mode, so I switch to HV just before reaching the hill, and the system appears to switch over. However, the EV miles continue to drop as I proceed up the hill. Is this normal, or should I be switching much earlier?

Ok, I know it's a confusing post title. Bear with me the steps to reproduce:
Deplete all EV range and Prius goes into HV mode
After engine warms up, skillful use of the accelerator can keep the system in "EV" mode by not going to the RIGHT of the throttle indicator. I have been able to drive a few miles in HV mode, but only using EV without the ICE firing up.
What I noticed is that those pseudo EV miles are counted against the HV range and NOT the EV range. I worked hard to get that extra mile of EV. It would be nice if it didn't count against HV!

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.

I had my brand new plug in prius for 6 whole days before my house was hit by lightening, while the car was charging. The car has been in the shop for 3 weeks since that has happened and they eventually replaced the "electric vehicle recharge unit". But it still doesn't seem right to me. one of the things that is happening is that the EV switch is not operating while I'm driving.
For instance: I'm driving locally on EV and then get on the highway and when I get to the point that the engine kicks on, I hit the EV switch to turn it off and move to hybrid mode. However, even though the EV light is off, the battery continues to discharge and will eventually completely discharge. To prevent this I do a number of maneuvers like hit the brakes repeatedly or hit every button the dash (EV, ECO) until it stops!
This cannot be normal but then again I only drove the car for 6 days before lightening struck. It also happens the other way. If I'm driving on the highway and get off and then hit the EV switch to turn the electric back on, the electric motor doesn't kick in.Am I imagining this? Is there some fancy way to switch EV and back on the fly?

If I'm driving around town and have to accelerate to merge with traffic, the ICE will come on even though I'm in EV mode. I understand why that would/should happen. But why does it stay on for so long after that? It seems like it stays on for several minutes, even if you're driving slow after the the few seconds of acceleration. And I've noticed a few times under the above circumstances that the ICE is clearly on (I can feel it's on) but the dashboard indicator shows it is off. What gives?

Yesterday while driving on the freeway in EV mode, my PIP (one of the first delivered to the states) flashed the "Check Hybrid System - Stop the vehicle in a safe place" message. I was near my house so I just went home. My SG2 showed code P0C3E, which is apparently an inverter over temperature code.
Took it to the dealer this morning and they just informed me that the car needs a new inverter, but no other details… "internal fault" is what he said.
While googling, i found this recall notice:
Green Car Congress: Toyota recalling about 701,000 Gen 3 Prius vehicles in US over software issue in inverter assembly
that doesn't talk specifically about the PIP and implies that it is a software problem, but goes on to say if the car is in a fault condition the inverter will be replaced. of course, it's possible that a software problem leads to hardware damage.

How to travel at freeway speeds in a Prius PHV and cause the EV miles to deplete?
To explain, I regularly travel between two homes with charging capabilities. One is three miles from the highway, the other one mile. If I use EV driving to and from the highway, and travel on the highway in HV above 65 MPH, I arrive at the other destination with about 10 miles of unused EV mile capability. I would like to use this extra electricity to improve my HV mileage.

I am very disappointed with my Toyota Plug-in because I have only had it 2 months and have 1400 miles on car. When I first charged it up with the 110 volt charger supplied with the car, I got 13.5 miles to use up before the car went off battery. Then on recharges, every two or three times when the battery recharged the usable mileage dropped by a 1/10 a point. I now have only 9.5 miles to use before I go off battery. When I first got the car I could go to work and have 3 miles extra to go home on. Now I cannot get all the way to work. I wonder how low it is going to go? I took it into Gladstone Toyota and had the service department look at it. They said after they recharged it and found it to be only 9.5 and that there is nothing they can do unless the red warning light comes on saying that the battery is defective. I asked them how low the battery would go and still considered normal, and they said they did not know. So I guess I will keep loosing free electric miles.
My getting progressive lower usable mileage has nothing to do with my driving habits as they have been the same since I started driving the car.

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.

You can put your car in drive, but also, you can put it in the "B" position. What does that do? How do you best use it? And what does "B" stand for anyway?

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.

Got my PHV on May 10th.
First charge showed an estimated range of 12.4.
Second charge showed 11.x. 3rd showed 10.x.
Now and for the last three weeks it only shows 9.4!
Charging with 115v.

On average, how many miles do you average between fill ups. I understand that this is all dependent on everyone's respective commutes, road conditions, ability to charge at work, etc., but i'm interested to know what you all do on average.
I'm still on my first tank and have 905 miles with one bar left on my tank.

My wife and I have 2013 PIP (His and Hers) and we compete for highest EV miles. Her car has had consistently recharged with 14- 15 estimated EV miles. This morning she called me and said as she left the garage she noticed that EV miles were 18.4. I thought wow wish mine did that. We just finished charging hers again and I went out to verify and I was blown away when I saw 20.9 EV miles. This can't be correct, what could be happening?

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.

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.

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?

I've noticed occasionally my music goes silent for a second or so when the iPod is plugged into the USB port. But then it will play without missing a beat for long periods. what could be wrong? No skips when using the aux plug.

I'm convinced this is a real problem with my 3-month-old 2013. When I bring it in for the 5K service, soon, this will be my No.1 issue. When running in EV mode, if you happen to start the ICE it will continue to run when you stop. In fact, it races - it doesn't just idle. I've tested this by being stationery for up to 5 minutes. This occurs not just the first time the ICE cycles on and off - it's every time. It only stops while driving (or by powering off).
