Toyota - Prius :: 2012 - Mileage Decrease Upto 50 Miles Per Gallon?
Oct 14, 2012
I bought a 2012 Prius new and averaged just under 53 miles per gallon for the first 15,000 miles regularly. I have a long commute so my driving mix of city/highway is pretty consistent. When starting the car one morning there was a fairly loud series of clicking sounds from the engine compartment, which then stopped. From that point forward the mileage has dropped to just under 50 mpg. Same driving habits. I am bringing the car if for it's 20,000 mile check up shortly. Any ideas if something happened to the battery I should ask about? It is still under warranty.

My 2000 corolla has consistently gotten 35 MPG until last month, suddenly I've dropped to 18-20 miles per gallon, a friend suggested fuel filter fail, but i can't discern if it has an external one...

Recently returned from trip from Austin Tx to Monroe LA. Gas mileage decreased from about 43.3 MPG to 38.5 MPG. A little annoyed by this but I guess I can attribute this to the increased weight in the vehicle. Still taking care in for other thing. Maintenance needed light came on & I assume it may be for a 15,000 mi checkup since it is nearing that mark.

We picked up our 2009 prius about a month ago from a local dealer. At the time it was getting about 52 miles per gallon. Since then, we have driven about 1000 miles and now we are getting only about 41 miles per gallon. Are we doing something wrong that made the MPG drop over 10 miles per gallon.

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...

Recently, my 2006 has been showing a decline in MPGs. I purchased a K&N filter several months ago hoping that it would work in getting better MPGs. I also watch my tire's air pressure, but the MPGs still fall off. I used to get around 43mpg in town and 45 to 47 on the highway. Now, I'm lucky to get 39mpg no matter where I'm driving.
I've been thinking of changing the spark plugs since I'm sort of grasping at straws. Also, someone told me that the older the battery pack (NHW20) gets the less MPGs I can expect. Maybe true maybe not! My Prius has a little over 60,000 miles on it and it shouldn't be loosing MPGs.

My 2007 (with Nav package and aftermarket Sirius radio) recently started losing channel settings on the Sirius (not on the FM radio!), the dash clock resets, and, recently, the miles-per-gallon and miles driven since last fill-up reset to zero. These events are sporadic, but have started occurring more often. The dealer seems unable to figure out the problem.

This is different from the MPG display that was on my 2010 Gen 3. Is there a way to set the display to show one decimal place.

I have a 2004 volkswagen jetta wagon, 2.0l bev engine, 5 spd. I just recently replaced both oxygen sensors due to codes that popped up, but have noticed recently the gas mileage and performance have decreased. Now I get the code 16804 - Catalyst System; Bank 1: Efficiency Below Threshold P0420. The car passed smogged and all the readiness codes passed. One major noticeable different, is when I apply the gas, it is not accerlating like it should.

The stock 265/75/16 tires need to be replaced and I was considering swapping 285's on the stock wheels. Will I notice an increase in fuel consumption? I realize that calculating mpg will need to be adjusted due to larger tires since the speedometer will be slightly off.

I just bought a 08 Screw with the 5.4 3 valve, 4x4 with the 373 gears, and 25,000 miles on it. I love the truck, but what is the best that you have gotten for mileage on your trucks with the 373 gears? Does it do better at 75 mph or 55? I haven't checked mine yet so I am wondering what to expect...

My 03 2.7 has suddenly lost around 4 MPG in city driving. Haven't taken it out on the highway to know where that is at. Used to get around 20/21 and now I'm around 16/17. Mileage is at 97k now and has new spark plugs and brakes done recently. I know the brakes are not dragging. All the fluids are fairly new and the car drives the same as before, I can't feel a difference in performance. Just lower gas mileage. I haven't changed out the T-stat yet, but the temp gauge in car reads the same as always. I checked the car with a code checker and there are no pending codes. I know this is the age where the oxygen sensors could start to go bad and have never replaced them.

I had a check engine light on my 2005 Ford Taurus and my mechanic suggested cleaning the mass air flow. Afterwards, the light was off and the car seemed to drive fine ( it was driving fine even with the check engine light on) But my mileage dropped drastically. On the freeway it went all the way down to 10mpg! Right now around town it is fluctuating a bit, but around 14mpg. Should I have the mechanic check for a loose wire or something not connected properly? Or just replace the darn mass air flow?

So, I've now had my 2015 F250 6.7 Diesel for about 2 weeks and I just turned over 1000 miles (damn I love driving this truck). And, I'm dying to find out if my mpg experience coincides with any other truck. With no load I am consistently getting right at 22.5 mpg at 70 miles per hour. With all in town driving and no load I'm holding right at 15 mpg. And I've noticed something else that seems odd. I'm actually getting a little worse mileage at 60 and 65 than I do at 70 miles per hour. What is going on there? Do these engines get a little better mileage as they get more miles on them?

My 2012 Prius v (lowercase v) has about 80,000 miles on it, my work commute is 180 miles round trip daily. I had been getting 40-44 for about the first 18 months of owning/driving the exact same commute. In February I noticed when I filled the tank that the range showed around 370, which seemed odd, it was always over 400. I started tracking my mileage and it declined quickly. By mid-March I was getting a range of 320-340 with each fill up, and calculating MPG of 29-31. The dealer has had the vehicle for over a month now and can't find "anything wrong with it". Ummm, the MPG has dropped about 30%, isn't that something wrong?

My 2010 Prius since new, during cold Central IL weather, when I pull out onto the city street, it accelerates VERY SLOWLY no matter how I work the accelerator for 1-2 blocks. Then it takes off normally. When I forget to allow the extra time, it can be scary to have a car coming up fast and not be able to accelerate. I have left it at the dealership for 3 overnights now over 3 years. They went from "couldn't duplicate" to "there is a slight hesitation" that they attribute to normal shift from electric to gasoline. The next morning it took 2 blocks before it kicked in. My gas mileage has only been 35 this winter; I don't believe it has ever been consistently that low.

My Plugin is only about 4 months old, but the EV mileage range is now down to 9.8 from 12.4 from the first very first day I charged it overnight. This with HVAC and fan off.

My 2004 has 132K miles and still running great. We now have a PIP standard model as well. I can't find a screen that tells what the overall mileage per tank is. Does it exist on this car?

I was driving up a hill today at about 30 mph with .9 miles remaining showing on my EV battery meter when all of a sudden it drops to 0 EV miles remaining and shows only 2 of the battery level bars (which is very very low), and the engine of course turns on. What happened?
I promise I did not push the EV power bar over its threshold. I monitor that like a hawk. I also know for a fact that it jumped from .9 to 0, because I watch that part like a hawk. This part of the trip is near the end of my drive home and I've done it about 50 times so far with no issues. With .9 miles left at that point on the hill I have always been able to make it to my driveway with .4 or .5 remaining, so this is very odd.

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.

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.
