Prius (Gen 3) Fuel :: Mileage Has Dropped To 35 MPG
2011 Prius for wife. Mileage has always been upper 40s to low 50s until the last week or so, now she is seeing 35 mpg displayed.
I have asked for a check at fill up. I just pulled the car out to wash it and noticed the engine came on right away, same when I put it back into the garage. In the past we would get part way down the driveway before the engine came on. Also did a code check and no codes found
What are the approximate outside air temps? 40s am 70s pm.
Prius C Fuel :: Mileage Dropped From 45 To 40 Mpg
I've had my car going at 45 mpg the past 2 years. I just hit my 45k mileage mark. I drive mostly on the highway to work so getting 45 mpg is pretty good for me. This last few fill ups, I noticed my gas mileage has gone down to 40 mpg. I thought it was a mistake if it was just once but the last 7 fill ups has been that way. It just went down all of a sudden and has stayed that way.

I have an 05 Prius that I bought used. It has 59K miles on it. Recently I took it to the dealer for an oil change. They told me it didn't need an oil change, but did need an air filter. Afterwards, the mileage dropped from about 47 around town to about 42. Had the oil changed a week later, and the mileage is now about 40 around town. The dipstick when cold shows a little above the full mark.

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?

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 have a 2005 Prius that I bought about 1 year ago that has about 75k miles. According to the display, I have been getting about 5.5l/100km (~43mpg) up until I did some maintenance in July.
A friend changed the oil, oil filter, and cabin air filter. Also, right around this time I bought a new set of tires. For some stupid reason, I had the idea that it had run flat tires, so that's what I bought & by the time I realized my mistake, it was too late.
Prius (Gen 2) Fuel :: 2009 - Mileage Dropped After Tire Rotation
I had my the tires on my 2009 Prius rotated a while back. My car has 36,000 miles on it all on the original tires. It seems like my mileage dropped a bit since doing that. There are so many variables in mileage though, it is hard for me to pin it down to that. Could tire rotation affect my mileage?
View 4 RepliesPrius 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.
View 15 RepliesJetta - Volkswagen :: 2004 - Reoccurring Misfire / Dropped Mileage
Recently (5 weeks ago), my 2004 Jetta misfired, which caused the car to shake very noticeably, especially at lower speeds or while idling. The misfire was accompanied by the smell of fuel on the driver side and triggered the check engine light to flash. I took it to the shop (a VW dealer). They ran diagnostics, found it signaled a misfire (but no other major issues/sensors) and told me it was due to the spark plugs/wires. I was dubious, as they were not too old, but I allowed them to replace them anyway, as they assured me this would fix the problem.
Just this week, however, another misfire occurred, also accompanied by the smell of fuel and shaking. This time, the check engine light remained on (constant) for 2 days, and on the third day, it was off. I brought it back to the same shop to try to figure out the real cause of the misfire, which obviously was not the previous spark plugs. My city gas mileage has also decreased over the past month - down to about 20-21 mpg from 23-24. What could be causing such a reoccurring misfire without signaling an issue with a sensor or other part?
Volvo - XC70 :: 2000 - Gas Mileage Dropped Even Have To Accelerate Going Down Hills
The car has drastically dropped gas mileage from 17mpg to 11-12 mpg. It's laboring, and I even have to accelerate going down hills where I am usually breaking to keep from going too fast. I have had the whole car looked over twice -- timing belt was a little old, so we replaced it. The gas filter was full of gunk, and it was replaced. Still has the same problem. Mechanic can't find anything else wrong. I'm getting ready for a long road trip and don't want to pay for all that gas or break down along the way.
View 10 RepliesPassat (B5) :: 2002 - Changed Spark Plugs But Gas Mileage Dropped To 24 MPG?
As far as I know, my Passat has never had any other spark plugs other than OEM. I could also swear that those OEM plugs always had 3 grounds. My gas mileage historically averages about 27MPG in a mixed city/highway environment.
Recently, my spark plugs were replaced and now my gas mileage has dropped to 24MPG. I had a similar problem once with my previous car (1998 Jetta GLI) and it was due to going from a three ground spark plug to a single ground plug. Putting in three ground spark plugs instantly restored the gas mileage to previous levels.
I've read repeatedly that the NKG PFR6Q is the OEM plug but it only has a single ground. I realize that my memory could be faulty, but this is driving me nuts.
Alas I can't be sure what was there before versus what's there now, but I know my previous mechanic was a stickler for OEM parts. Would switching from a multi-ground to a single-ground cause a 10%+ drop in mileage?
Prius (Gen 2) :: Red Triangle Appears When Steering To Left
My partner's Prius is bring up the red warning triangle. She had a system diagnostic carried out, which brought up these two faults:
C1241 Low Battery Positive Voltage
C1300 ABU ECU Malfunction
The faults were reset, but it was only a short matter of time, before the red triangle appeared. My partner tells me this tends to happen more frequently when she is steering left and in colder weather.
She was advised the ABS ECU will need to replaced (it does says "new actuator" on the paperwork)

View 4 RepliesPrius (Gen 1) :: Input Vol Error Appears When Charging Battery
I was wondering how I would charge my gen 1 battery cells and balance them with my IMAX b6 lipro battery charger. Every time I try to charge it or hook it up the thing keeps saying "input vol error". Now I don't know if that means I need a different ac adapter since I'm now using a 19.5 v laptop charger and most of the time they use a 12v ac adapter.
Most of the cells have a reading under 6v but we have 38 new cells coming in today. How we can balance them with this charger because I know it has a balance charge setting for the lithium batteries. That has a separate plug though. Should we just put the cells closest to their voltages and have them balanced that way?
Prius (Gen 2) :: Hybrid Battery Level Appears Incorrect On MFD?
The Hybrid battery level appears to be higher on my 2007's MFD, when compared to my Scangauge ll. For instance, the MFD will show the pack almost full, yet the Scangauge says it's only 67%. Not sure why this is happening. All I know, is that both gauges used to provide very similar data years ago.
View 8 RepliesPrius (Gen 3) :: Need To Pull The Door Handle Otherwise Key Not Detected Appears
Over the past month or so, my 2012 Prius Three is being strange. I always keep my key fob inside my purse. Sometimes I have to pull the door handle a few times before it will unlock. Other times it will say key not detected when I try to start the car. I will have to try a few times before it will start. Or the strangest thing is, sometimes when I pull over before my husband and I get home, and when he gets out of the car (I have NOT turned it off) it will display the message, key not detected.
The thing is, he does not carry a fob with him, the only key is in my purse, which is inside the car with me. I thought maybe it maybe it was the key fob so I swapped out the fob I was using with the 2nd one we have and it is still happening.
Prius (2004-09) :: Red Triangle Appears When Braking On Hill
I am just trying to find out if this means I need to have something checked like coolant hardware/fluid...
It is over 100 F these past several days and at 35 minutes just hopping off the freeway, and then again today, coming down a big hill at another part of the freeway, I noted that as I quickly had to brake the system made the computer noise (same as when I switch from the power view to the trip view), red triangle comes on, no other indicators. The first time it happened I was back on the throttle almost right away and red triangle went back off.
Everything fine. Same today but it was on until I was back on the throttle at the bottom of the hill...

Prius (Gen 3) :: 2010 Engine Starts To Shake, P3191 Appears
I have a Prius 2010, 4 years old with 144.000 km.
The last 3 night we had temp. below freezing point. So every time I started my Prius up at the morning, the engine starts to shake violent, and then automatically shut off the engine with a message on the screen "Check Hybrid System". So after several times I restart the car, it runs normally, still with the message on. The temperature outside was -1 degree Celsius.
So I used my OBD to pick up the codes, which says P3191 - Unknown Error.
What does this error mean at what could cause this problem?
