Prius (2010-12) :: Traction Battery Gone To 1 Bar - Mileage Down?
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

Have a 2009 with 25K on it, purchased in April when they were practically giving them away. Recently did an oil change and got snow tires, then left my husband in car with heat on for 20+ minutes, and now mileage is in the 30's and the battery isn't charging itself or regenerating. What could be going on?

View 9 RepliesPrius (Gen 3) Fuel :: Mileage Has Dropped Significantly To High 20s / Low 30s
The last few days with snow and temps dipping below, my mileage has dropped significantly to high 20s/low 30s. I understand that (a) I park my car outside, (b) warm-up my car during the time I clean the snow, (c) no EBH, (d) no grill blocking, and (e) my drive to work is only ~15 miles round trip, but still mileage in the high 20s/low 30s is lousy, even lower than my break-in mileage (30s) that occurred in Jan. Even, my 1995 Corolla with 150k miles also gives about mid-20s during the winter with identical driving styles and conditions. So what's with the Prius?
View 19 RepliesPrius (Gen 2) :: Poor Gas Mileage And Transmission Not Going To High Gear?
My 08 has been getting poor mileage for the past 3 weeks or so ..... I tried a "push the power button and trip reset shift to reverse to eliminate the backup beep" mod and it did not work. However I find now that I cannot get my MPG average above 42. When I tried the mod the odometer went immediately to all bars and then the bar indicators went out one by one until the regular odometer reading came on .... I'm wondering if doing that also set the car into another "mode" where the tranny will not shift to a higher gear???? So symptoms are constant engine running when cruising to a stop and after 20-30 seconds the motor will shut off .... and while driving on the highway the engine will pick up at least 1000 - 1500 rpms just by adjusting the accelerator a smudge .....

Bought a 2013 Prius V with 3000 miles on it over 1 year. The car has only been driven 1000 miles in the last 7 months or so. I am worried this might not be a good thing for the battery(s)? Is there a Diagnostic test I could request that would determine strength of the batteries? Other hybrid parts?

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.
Prius (2010-12) :: Mileage Drops To 2 Bar Within A Mile
When I bought the car in 2009, if I had 4 bars on my traction battery at night, it would have them in the morning. Now I can leave the car for 2 hours in moderate weather. When I drive off, it will show 4 bars but driving in eco mode w/o ac, it will drop to 2 within a mile and stay there for several miles before it starts to charge again. My overall fuel economy has dropped 10%.

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) :: After First Oil Change Mileage Is Lower
I went to the local dealer at about 6K miles to get the free 5K service. The invoice said synthetic service, so it should be the 0W-20. Now the average mileage since the last fill-up is lower by at least 3-4 MPG. My driving habits haven't changed. I inflated the tires to above 40 PSI. I looked at the oil. It is medium amber colored. (I forgot to look at it before the oil change. )
View 19 RepliesPrius (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.

The humidity has an affect on my MPG. I noticed that my MPG went from 49 - 52 MPG down to 44 - 46 MPG when the heat & humidity started here in June. Yesterday a cold front came through and the humidity dropped. I filled my tank up and noticed my MPG is back up to 49 MPG, so the only thing that is different is the humidity. The cold & humidity does affect the MPG (approx 4 - 6 MPG).

I don't have a lot of data yet, but the last couple of times we had temps over 80F, my mileage took a significant hit - about as bad as when temps are below 20F (more than 10%)... Shutting off the A/C doesn't change things much...

I am using a 2012 Prius and I was running around 23KMpL average. For sometime I am seeing my mileage around 17 - 18 KMpL. What could be the reasons for this ?
The only change happened in between is that I had a accident which I had to replace the front buffer.
