Prius (2010-12) Fuel :: MPD Dropping With No Identified Reason
I am the owner of a new 2014 Prius Two as of three months ago. I have really been enjoying the car, and it is certainly more friendly at the pump than my old Chevy Tahoe. I have a question as to why my mpg has been getting worse of late.

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.

Just had my first battery boost for my year-old Prius 2K10.
This morning I went to start the car, it didn't open the door for me, then I had all troubles in the world turning the key ... And obviously nothing was opening, no lights, nothing.
I had my car boosted. First time they put the booster, I couldn't start the car (everything showed up but starting the car didn't start the conventional motor - the lights were all on). They unplugged it (everything disappeared yet again) and plugged it back in ... Then I could start my car. Of course, everything was reset: time, trip meters, everything.
That's where I noticed my battery indicator was half-full.
Prius (2010-12) :: 5 Beeps That Happen At Any Time Of Night For No Apparent Reason
I have a 2010 Model I with only 19K miles on it (purchased new). For the past year or so, at any time throughout the night it will give out 5 beeps for apparently no reason. I have reset the system by disconnecting the alternate battery and have used a PocketScan Plus to test the systems which shows no problems.
View 5 RepliesPrius (2010-12) Fuel :: Temps Have Been Dropping, MPG Dropping As Well
Grill blocked today for the first time and have a couple questions.
Temps have been dropping more these last 3-4 days and have noticed my MPG dropping as well so I thought I'd try grill blocking.
Tempts have been and will be high 30s-low 40s in the morning and upper 50s to mid 60s for the high.
At first I just wedged the pipe insulation and drove one trip. I didn't feel comfortable that it would hold for the long haul so I added zip ties.
I used two pieces of pipe insulation 1/2 inch copper / 3/8 inch iron. Up close it looks like 2/3 or 3/4 of the grill is covered.
My two questions:
For fWT, at what temperature should it not exceed?
At what outside temperature should I remove the pipe insulation? In the Phoenix area, temperatures rise in March and sometimes we will have a short period of warmer than normal temps in February. I just want to make sure I do not cause overheating.
Prius (Gen 3) :: 2010 Mileage Is Dropping Than Usual
I just bought a 2010 salvage Prius. I have another 2010 I have been driving for 3 years so I am pretty used to the mileage I can expect under different conditions.
When the car is totally warm and I measure the mileage for 15 miles or so I get normal readings of mpg. But with a lot of 2-3 mile trips during the week I am getting about 10mpg less than usual compared to my other 2010.

There is roughly 800 on the odometer and I was averaging around 35 mpg. I filled it up and driving home afterwards I noticed the mpg drop off significantly. Now I'm lucky to get get 27. It was as low as 16 on the trip computer. The range was the same and the miles come off in sync with the odometer. I'm wondering if its a glitch with the trip computer?

While most of the emphasis I've seen on improving fuel economy seems to focus on warming the car up quickly in cool/cold weather, I seem to be experiencing significant mpg drops at the other end of the spectrum.
View 8 RepliesPrius (Gen 3) :: Check Engine Light Came On - No Apparent Reason
A month ago my check engine light came on so, after checking to ensure the gas cap was screwed on correctly, I did what the manual recommended and took my car directly to the dealership. After paying a diagnostics fee and losing my car for an entire day while they ran tests and contacted Toyota, my dealership told me they couldn't find a problem and just reset the indicator.
Within a few days the light came on again but before I had a chance to take it back to the dealership it went off. Now some 3 weeks later it is on again and I'm wondering what to do.
Prius (2004-09) :: 2006 - MPG Dropped With No Apparent Reason
I have noticed a significant (15 to 20%) drop-off in mpg in the last 6 months or so. My 2006 prius at 95,000 miles is just short of the warranty on the battery pack. I brought it into the dealership and they ran the routine computer diagnostics and said everything looks good. I fully expected them to tell me that the performance on the battery pack had fallen off, so I was a bit put out. The guy actually got a bit defensive with me when I asked him some further questions about what the criteria are for determining whether the battery back was performing as it is supposed to in order to get the maximum MPGs.
View 3 RepliesPrius Plug-in 2012-15 :: ICE Startup For No Apparent Reason
I just had the ICE start on me for no apparent reason. I was driving down Santa Monica Blvd this afternoon. I was accelerating very lightly on a slight down hill and the ICE came on. I looked at the dash and it showed I was in EV and less than 1/3 the way to the power portion so that rules out accelerating too hard. At the time my speed was around 30mph. Temperature was 70 degrees so no heat or AC. The battery was at about 50%.
The only thing I can think of is that it came on because I hadn't run the ICE in a very long time. My trip B indicated that I had done 114.7 miles since the last time the ICE fired up. That's about 184 kilometers but I know that it is supposed to fire at 200 kilometers (about 124 miles). ICE firing up earlier than 200 kilometers?
Prius (2010-12) Fuel :: MPG Dropping - Replace With New Tires?
So I bought a used 2010 Gen 3 with ~26,000 miles on it in July 2013. I started out getting 48-52mpg depending on where I was driving. I live in Raleigh, NC and I did notice a drop in drop in MPG over the winter ranging between 44-48mpg but the mpg never rose again as the months warmed and I averaged 44-46mpg for most of the summer. After changing my tires a few weeks ago I've dropped to about 40mpg regardless of where or how I drive. I bought Pirelli P4 Four Seasons 195 65R15 91T and have them inflated to the levels recommended by Toyota. 35/32 or something like that. Is it the tires or is there some other possible issue?

View 19 RepliesPrius (2010-12) Fuel :: Mileage Uphill And Down
So, I was in Wash. State for a while this month and rented a Prius. I decided to check some mileage on mountain roads, and here's what I got. All of these are indicated by the computer, so they are probably 5% or so high. Unfortunately, I did not see either the maximum incline or average incline of these roads posted anywhere, so unless someone else knows them, these numbers are not worth too much scientifically:
UPHILL:
Going uphill on I-90 to Snoqualmie Pass from the West (from Seattle), at 70 mph (the speed limit), fairly steady, with a few decreases for traffic and curves: 18.6 mpg.
Going uphill on US 97 to Blewitt Pass from the north at 50 mph, also the speed limit: 27 mpg.
Going uphill on the Olympic National Park road to Hurricane Ridge, speed limit varying between 35 and 25, with a couple of sections as low as 15 mph: 22.1 mpg. (Maximum incline here might have been 6 or 7 percent).
On the Hurricane Ridge road, I reset the Trip Meter A about a mile from the top (interestingly both segments of the uphill trip registered 22.1).
DOWNHILL, mostly:
The Hurricane Ridge downhill produced an interesting number, because I didn't reset the thing at the top, so I had a mile of 22.1 mpg at the beginning. You go down for about 18 miles, losing about 5200 feet of altitude to nearly sea level (Strait of Juan de Fuca). We kept driving, and at 24.7 miles (so about 6 miles of driving near sea level), the mileage gauge still showed 99.9 mpg. (I took a picture, but it's too fuzzy to put in here.) It was a couple of more miles before I noticed that the trip mpg was down to about 91.
Prius (2010-12) Fuel :: Winter Mileage Very Low 42 - 43?
Temps average maybe around 10-15F in the winter so mileage won't be great. Tires are up, grill is blocked. We're getting about 42-43 on the HSI which means about 40 mpg in reality (I've checked this many times and Toyota is off by 3 mpg on average in our car). But Mike in Maine shows up with a 60+ mpg in 15F temps, and I know my fellow Alaskan, Spiderman, is getting 50+ easily. My commute is more highway than stop and go. I don't use P&G but I'm very gentle with the go pedal. I feel that I should be getting closer to 50 here, even with the temps. Is this too much to ask? Maybe it is...

I have 2600 miles on my 2012 mdl II. A month old. I have been averaging 47.5mpg since day one based on miles driven and gas put back in tank at each fill up. I have used only Mobil bottom 87 oct gas.Last fill up got me 48.2, very nice, then I filled up with mid grade 89 oct as it was all I could get then. The next day I was in the dealer for my 1000 mile checkup. when I got out my battery was down to 25%, okay no biggie. Then from there on out I notice my mpg changed alot. The comps used to read 49.1-50.1. Now it reads 42.2-44.1. I drive the same way and my 85 mile round trip to work hasn't changed. My first fill up since the dealer, got me 45.0 mpg. wow a big drop off.

I commuted to LA 2-3x a week. The mileage on my car is now at 90k. I have had an average of 40 mpg since new, but suddenly it began to drop. We took it to our local Toyota dealer and was told it was most likely a cable that needed to be cleaned. That was $160. It didn't work.
