Prius Plug-in 2012-15 :: Drop In Estimated Gas Mileage While In EV Mode
While driving in EV mode I noticed my remaining estimated gas mileage drops. I watch the dash and the EV is constantly light and it doesn't appear the the ICE is coming on. Is this normal?

Why all of a sudden the mileage indicator on my 2012 suddenly dropped about 5 miles/gallon, both highway and around town? The car has only 9000 miles on it. Has there been a service bulletin regarding the "Eco'" mode? Having the "Eco" mode on or off doesn't seem to make a difference.

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.

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.
Prius (2004-09) :: 2005 - Cause Of Sudden Drop In Gas Mileage?
My '05 Prius has been going strong with just passing the 200k mark recently. However about 2-3 weeks ago after I replaced the PCV valve, I started getting really bad gas mileage. I'm talking about getting an average of 45 mpg in city/highway combo down to 30 mpg. Filled up my tank twice from empty so I'm pretty sure it's not just bad gas. Highway driving does slightly better than city.
Today I noticed that my acceleration from stop is just absolutely terrible. The car responds really slow and sluggish and takes a while for it to realize I want to go. Low speed doesn't get good mileage at all. It seems I get normal mileage at almost 65 mph, not sure why.
I don't think the 100 degree weather we are having here in Texas is causing THAT much of an effect because last year and two years ago during 100 degrees, gas mileage was normal. What to check? I searched and most talk about cold weather. I have a relatively new 12V gel battery so I doubt it is that but I can try disconnecting it.
Passat (B6) :: Sudden Drop In Gas Mileage?
I have an 08 2.0T and it just suddenly had a huge drop in gas mileage. I recently had new tires put on and an oil change (about 35k miles). getting closer to 40k miles now and wondering what could be causing this. Usually I get about 30-33 mpg easy on the highway. Now I'm getting 24-26 mpg. Already checked the tire pressures. they're to spec. no gas leaks from what i can see.
View 6 RepliesSubaru - Forester :: 2004 - Gas Mileage Sudden Drop
I have a 2004 Subaru Forrester with a 2.5L engine (non-turbo) and about 137,000 miles. I usually get just a bit more than 300 miles on a tank of gas. About 3 weeks ago, I took the car for a major tune up (and they also replaced a valve cover around the spark plugs area). After the tune up, the car was running great and I was still getting about 300 miles to the tank. Within the last 10 days, I noticed that the gas mileage on the car has decreased - I am now getting closer to 250 miles per tank. The mechanic rechecked the fuel lines and test drove the car two days ago but did not see any signs of leaks. The weather was near freezing for about a week but has warmed up again to the 40's. My driving habits have not changed and I am driving the car the same way as before. I am stumped as to why the gas mileage would drop that much. What might be happening?

My 03 (129k miles, 2.7 AWD) is up to date on all maint (this summer saw new timing belt etc., transmission service) and oil is current. Spark plugs are due at 131k. Air filter is new, tire pressure maintained at 30-32psi.
MPG has consistently been ~20, slightly more on trips. October 27 to November 26 was 19.8 mpg. Putting on brand new snows (General Altimax Arctic) knocked it down to 17.5 mpg for the next ~250 miles. However, since early December it's dropped again to 13 mpg!
Mechanic just checked for brake drag (none - rotating one wheel turns all 3 others easily); no pulling, rolls well in Neutral. No engine symptoms (missing, bucking) or CEL lights. Power seems a little diminished (for instance, it takes longer to shift during acceleration sequence).
I will add my Lucas Oil gas treatment just in case it may be injectors. My mechanic says he has seen MPG suffer from certain gas brands (and I do wonder if the tank fillup after which the MPG dropped had something to do with it).
Elantra XD (2001-06) :: Sudden Drop In Mileage And Hard Shifting
All of a sudden my fuel consumption dropped from 28mpg as read from the computer display in the dash, to 21mpg. This was not a gradual drop, it was at 28mpg one day and 21mpg the next day. There is no service light on, do these cars produce codes that don't trigger the service light?
A few months ago the vehicle was getting stuck in various gears and lunging, this was from battery corrosion dripping down and eating away at the transaxle range sensor. I cleaned up the battery and replaced the range sensor and the vehicle was driveable again. It re-learned the shift timing and seemed to be ok, then about a month ago it seemed to be forgetting the learned shift positions after sitting over night, I replaced the battery, thinking it was in a marginal state where it would forget the program while sitting. The shifting is still hard sometimes but this seems to have worked but, now my mileage is horrible.
I thought I'd just change out the oxygen and air flow sensors but, then looked at how much they cost now, and realized this would be some costly trial and error. Is there a methodical way to troubleshoot this issue, any way to pull the sensors and measure them?

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.

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.

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?
View 19 RepliesPrius 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?
View 19 RepliesPrius 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)!
Tiguan :: 2012 - Sudden Drop In MPG
Our 2012 Tiguan (FWD) has been experiencing a sudden drop in MPG for the past two weeks. We had no significant change in climate or driving habits. With mixed driving, we dropped from about 24 MPG to 20 MPG. We had our 40K service done just two weeks ago.
View 9 RepliesAccent RB (2012+) :: Extreme Drop In Fuel Mileage
I live in the suburbs, so I do a lot of stop and go driving. For the longest time, I would typically get 25 or 26 mpg city, as per the gauge. I would see the number climb to 41 or so in constant highway driving. I am pretty sure the fuel tank is about 10.5 gallons or so as when the low fuel light comes on, and there is only one bar left on the gas gauge, and I top up the tank, I never put more than about 9.5 - 9.8 gallons in.
All this being said, in the last few weeks I have seen a severe drop in MPG. The gauge is constantly reading about 19.5, when I hit the expressway it will climb a bit, but when I compare the miles driven to the bars on the gas gauge, the bars used to drop at about 20 miles driven, now each bar will drop at around 13-15 miles driven. We are having some extreme cold here in the midwest, as opposed to last winter when I bought the car.
