so I recently had my 2012 Prius in for oil, tires and alignment. I was getting 55mpg all day and now I can't keep over 45mpg. Tire press is 38 all around with Goodyear assurance. Could the alignment be off causing higher rolling resistance. Maybe wrong oil.
View 12 RepliesOk, so I was already getting pretty bad fuel economy from my 3.6 4motion wagon (14/24 city/highway). so last week I take it in to the dealer for 5k oil service. now after the service I get 10/18 (city/highway)!!!!
Car seems to run fine, but for some reason the fuel economy has dropped significantly. Most people on here say they get better economy after the 5k service.
Now the car is at the dealer for a few days for them to check it out. Gave me a old hyundai for a loaner.
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.

View 12 RepliesOK, I couldn't take it any more, I took my 2010 III Prius in for the oil/tire rotate and had them change the backup beep to one, how nice. Within three minutes of driving from the dealer, I knew something was different, it wasn't acting the same, in eco mode it acted more like power mode. I noticed my normal driving was giving me lower mileage, seems like the engine is running longer etc.
I took it back and they said no way the beep change would have done that, yeah I agree, but something changed. When in eco mode, if I am running along at a low speed and step on it, it gets up like power mode almost, it never did that before. They had it a couple hours, ran full diagnostics on it, nope, nothing wrong. It's almost like something go changed, upgraded to pep it up, yet it's yanked about 6-7 miles per gallon from me.
At my last dealer performed oil change, he writes "CDM front caliper service due next time". He says something about needing to lube the front calipers .....
Is this service that should be done, or is the dealership service department looking for a chance to make money for unneeded service?
I had 15,000 miles on my 2010 Prius at that time. If needed, is it something I can easily do myself?
I just purchased a new Prius a couple days ago. When is the first scheduled maintenance interval? My dealership told me 10,000 miles for the first oil change? I've always been under the impression that you need to do the first service as soon as possible with a brand new vehicle? To rid the oil off metal shavings and break-in oil.
View 11 RepliesDrove to work today and all was fine. Came out at 3 and started my Elantra up, dropped it into gear and it was ROUGH. Engine ran for a few seconds before I put it in gear. The shifts up the street were hard and the downshifts were equally hard. I put the transmission in manual--same thing. After a few minutes, the shifts returned to normal. No CEL. The car has 48,700 miles on it.
View 10 RepliesOn my battery poles I measure like 12.8v, my scangauge reports around 12.4v/. I have an additional voltmeter connected to the cigarette lighter cables & same thing there: 12.4v. The voltage go down soooo much. My first thought was that my battery is not getting fully charged, but after measuring directly at the poles, it's obvious that the voltage drop happens on the way.
View 16 RepliesMy 2007 Prius has about 105,000 miles on it. For awhile I was getting around 41-42 MPG which I thought was a bit on the low side, but the dealership never found any problems. I had the recommended 60k service done then after that stopped going to dealer for routine maintenance like oil changes and such. Lately though, my MPG has dropped to around 37. I use Chevron gas all of the time and I keep up with my oil changes. I try to also make sure my tires are inflated properly.
They had a special on oil changes at the dealer so I asked them what they thought might account for the drop in mileage. Their initial thought was cleaning out the fuel injectors. I do change my own air and cabin air filters.
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.
Well I shouldn't say MPG since we canadians use L/100km.
View 19 RepliesMy Father In Law bought a 2012 Prius C last year in Houston, they are from El Paso. The car drove great for many months, he takes the same path to work and same speed every day and was consistently getting over 60 mpg. All of a sudden winter came and he lost MPG and the engine would come on more often, even while parked. I own a 2009 Prius and told him mine did that too during the winter, because for some reason, during winter the battery drains while parked and the engine comes on to charge.
View 8 RepliesThe engine light went on and I took it to my mechanics who is good on everything except Hybrid system.
Immediate after the lights on, I filled gas and the mpg dropped to 31, soon back to 37 on a hot day 85 degree. At red light, I feel the engine still running, not very smoothly. But the next day, it back to normal, mpg also back to 48 something.
My friend has a 2005 with 140K also got the same code. His mpg dropped to 40 and feel that engine power is lower now.
I would like to know if this is a common problem, what's the most probable cause, and if there are many possibilities, what's the best way to approach.
Here is problem area by OBD-II:
Engine and ECT
Hybrid Control
ABS/VSC/TRC
Air Conditioner
Immobiliser
We recently got back from a 2800 mile trip. Our v now has 10,600 miles on it. We have been averaging 41 mpg until the last two tank fuls. For some strange reason we got 34.5 displayed on our last tank, 32 actual, and right now after 90 miles we are showing 30.5 displayed. My wife drives the car 98% of the time, but even when I use hypermiling techniques the car is not yielding the past displayed results. We are about to take it in for the 10,000 oil change.
View 8 RepliesI'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.
View 3 RepliesWhat should one expect during the 10K service? Is there anything I should ask for specifically? I already got some default settings fixed during my 5K visit.
View 1 RepliesI have Prius 2010 and I was getting 20 km/l to 22 km/l until I repaired the part which is between two tires and when you revolve your steering it revolve due to that rod. Right after I drive my car as I came out of workshop, it seems that my engine keep running more and turn off less.
1- Can I check if my Hybrid battery is getting weak or what is the health of my hybrid battery ?
2- Is there any way if I can check my front tires are revolving without any friction and revolving freely ?
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.
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 RepliesWe 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.
