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.
View 6 RepliesRecently, 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.
View 8 RepliesI 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...
View 8 RepliesI 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.
View 4 RepliesI have GX470 2007 (100k miles) and last weekend I noticed that I drove 60 miles (on streets) and gas needle was down to 1/2 of tank. When I went to gas station to fill up, I was able to get only 5 gallons and tank was full. I drove another 45 miles (on the highway), and needle already was down to 3/4 of tank. I did not have this in the past. I was getting 12-14 miles / gallon on the street and 20 - 21 miles / gallon on the high way.
View 6 RepliesMy neighbor stopped me this morning saying her 2005 prius was acting up.
When we started off the MFD was showing all blue bars, ac lights radio all turned off.
Drove less than 3 blocks and it dropped to one purple bar and had hesitation on acceleration.
Went around the neighborhood about 3 miles and it was showing full charge green , parked and restarted, it dropped to all blue bars.
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...
View 11 RepliesSo, 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?
View 3 RepliesI 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.
View 15 RepliesSo I met my wife after work. I was killing some time with my son. We drove across the street, then to a neighboring shopping center. I changed the display to see the more accurate instant MPG and noticed my battery was at 2 bars. This is the first time that's happened, that I'm aware of. During normal operation, it stays at 2 bars above the halfway mark, or above.
View 6 RepliesI 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 RepliesI recently got my 2007 Prius back from the body shop after a 13k repair following a crash that crumpled my front end. The car seemed to be doing fine, until a long, steep climb had the battery drop to one bar, speed dropping to 40 despite a floored accelerator, and a red triangle that appeared briefly before disappearing just as we completed the climb. It's the dropping speed despite a floored accelerator and the warning light that have me worried.
View 19 RepliesToday I went to the national car test (passed. but), when the car has been returned to me by the employee of national car test center I noticed one bar on the SOC. This happened for the first time.
Additional notes:
1) recently (about 4 weeks ago) I had to temporarily replace for second hand (20 bucks) 12v small auxiliary battery.
2) recently (withing last four weeks) I noticed high temperature in the boot compartment, I tried to investigate and the ducting leading from the HV battery was really hot, which means that my battery was really hot too.
I tried to explain this to myself that this might be due to HV operating at higher levels due to unknown state of the replaced 12v small aux battery (second hand product).
3) Today I noticed that technician at the test center used some spring assisted bar to press the brake on the car while he tested the car, I recon that maybe he have had powered off the car while doing so, is it possible that this might have contributed to the dropped SOC ?- it's just my guess.
I'm thinking to replace 12v aux battery to brand new battery and then test the operation of the fan and whether the temperature still rise. - is it good idea? Or should I just seek for the testing tool to determine the status of each of the modules?
If so, which testing device can handle this task? I heard from this forum about ELM obd bluetooth adapter. I use android device, would this be okay or should I look for another device perhaps scangauge?
I used to get 55-58 MPG when my commute was 65 miles one way, 85% freeway. But these days I noticed that when AC runs hard and trips typically 16 miles, 40 MPH, mpg dropped to 42-45. That worried me a little bit.
Driving style: conservative. I start off normally, but I use N gear as soon as passing speed limit. (this factor alone should enhance mpg by 10 I guess. I used this technique on my 98' Lexus LS400, 4 Ltr V8 engine, once got 38 mpg on freeway, while the sticker says 18/25). This is the main reason I worry that something is wrong with my prius.
Typical range: 16 miles, all local.
Tire pressure: 40 psi
AC runs hard, outside temp 90 degrees, I set temp to 72 inside. (I guess this is the main reason for mpg drop, but I don't think it should drop that much)
I recently changed oil and trans oil.
My battery is a little bit weak, but no warning light. If I forget to turn off head lights, it needs jump in 10 minutes.
Mileage is 143K, 2004 model.
Water pump changed by Toyota free of charge.
Any clue? or it sounds normal and I don't need to worry about it?
So i had been up in the woods for better half of the day. I had been in 4wd a few times, didn't thrash on anything and while driving home about 30mins into the return trip on the pavement i noticed my speedo only showing 10mph. I know i was easily going 50mph. I changed my SGII gauge to show MPH and sure enough i was going way faster. Eventually the needled dropped to zero and stayed that way for at least 5 miles. Then I came to a stop to and made a right turn giving it a bit of throttle and the speedo began to work correctly and did so for the remaining 5 miles. the Odom also during that time wasn't adding mileage. could this be from the rear sensor ontop of the rear diff?
View 6 RepliesToday the flow rate of the air out of the vents on my Prius has noticeably dropped.
It makes no different which vents I select (front, feet, or windscreen).
The blower seems fine - it's still making its normal noise.
The air still blows out nice and cold, there just isn't much of it coming out, even on full blast.
I've pulled the cabin air filter and checked it's not clogged, so it seems like there must be a blockage downstream of the blower.
I had the cruise control set on the speed limit going up a hill. Half way up, the cruise control dropped as did my speed from 70 to 56. There were no warning lights but the battery meter was in the one bar pink range. I managed to continue up the hill at 56 mph by flooring the accelerator. When I got to the top and started to regenerate power to the battery, I regained power and speed. I am discussing a 2008 Prius with 89k miles. What the issue may be ( like battery pack declining efficiency)?
View 15 RepliesMy 2005 Prius started showing all the symptoms of a dead/dying hv battery this morning. The dashboard lit up, the battery fan kicked on and my mpg dropped to 35mph. I was half way to work, so I just continued. I have been checking around and I can get it replaced for about $1000.00 reconditioned, but they have a 7-10 day waiting list. The dealership wants $3500.00 minimum, and says that I should not drive it at all and have it towed. Is this true? Can I drive on gas alone until I find a solution?
View 19 RepliesI own a 2007. The problem i noticed was that while driving, the AC. was on and suddenly the fan speed dropped and the horns sound also became dim. this was hust like experiencing a loss in power as happens when the voltage drops and the machinery slows down. This persisted for a few minutes to recover back to normal automatically.
This happened a couple of times and then the master warning light and check engine light came on. A couple of weeks back the radiator fan motor dysfunctioned and had to be replaced. I am really concerned as to what is wrong as none of the mechanics have been able to satisfy me with a diagnosis ...
2006 price with going back - rest about 105K miles on it. Recently the dashboard lit up like a Christmas tree with all the warning lights. Battery fan runs non-stop as soon as the car is started and if driven, the gas engine never turns off. When it happened I was circling the neighborhood looking for parking. After about 5 minutes the car dropped out of drive and wouldn't go back in until I shut down and restarted. The battery still charges, and holds a charge when left parked. What is most likely the culprit before I bring it in this afternoon? The dealer is 3.5 miles away (about 15-minute drive in Chicago). Am I risking further damage driving it in? Should I call for a tow?
Update: A check of the inverter coolant reservoir shows that coolant is flowing. Ripples on the surface.
