Subaru - Outback :: 2015 - Gas Mileage Has Been Steadily Dropping
Feb 10, 2015
Gas mileage as stated by Suburu for the 2015 Outback (2.5 engine) is 25-33 with a combined of 28. Mine has never attained that and it has been steadily dropping. Now it is displays as 19 mpg. It is new and has just under 500 miles on it, and I read that the break-in is 1000 miles. That being said, shouldn't I be seeing better MPG than that?
BTW - I am hoping that I am just not being fair (to the car and to Suburu) and that I'll be up in the advertised MPG's soon after I hit 1000 miles.

My 2007 Prius (72k miles) has been dropping in MPG steadily for the last 6-8 months. Where we would get a strong 42 mpg, we are now experiencing 34-36 mpg. After a 400 mile trip to the coast, we just experienced a 34 mpg average. 1 year ago, we would have seen 42-45 mpg on the same trip.
I had the dealership check it out, only to tell me the computer says nothing was wrong. This is the 2nd time I've voiced this concern about the car in 12 months. They told me to replace the tires. We did. No change.
I checked the 12v battery through system check on the display screen (method I found on this website). It was showing 12.4v for an unloaded battery. When i put a load on it, it dropped to 11.7v. Once I had it charging, it raised to 14.0v.

I think I'm getting the hang of this car after 3 months. My mileage has been steadily increasing as the weather has gotten warmer and as I've adjusted my driving a bit. If I drive fairly normally i get about 55 mpg (HSI, ~52 mpg actual). If I'm more careful I get closer to 60 mpg HSI. If I'm really careful I get over 60. My last tank was 61.8 (HSI), and 59.6 mpg from the fillup (see attached). I put 10.13 gallons in the car for 604 miles. I call that 60 mpg, and I'm pretty pleased. This is for a week of normal commuting which includes lots of hills, about 1/3 surface streets, 1/3 state highway, and 1/3 interstates with occasional stop-and-go. It is pretty hot here these days so the AC runs constantly. I have only seen my mileage get better with time so I haven't seen it roll over as the weather has gotten really hot, but that may be that any affect is counteracted by my learning to drive this car.

I just bought a 2010 salvage Prius. I have another 2010 I have been driving for 3 years so I am pretty used to the mileage I can expect under different conditions.
When the car is totally warm and I measure the mileage for 15 miles or so I get normal readings of mpg. But with a lot of 2-3 mile trips during the week I am getting about 10mpg less than usual compared to my other 2010.

I have noticed over the past few months that my gas mileage is dropping (from about 29 to 24) on the highway and I seem to have lost some power. I know the car is getting older, but where do you think I can get some of it back? The plugs are only 20K old and the air filter is new.
It is a 2004 1.8t with 109k on it.

I have a 2004 Chevrolet Tahoe 2WD with the 5.3L V8. Tahoe has 134K. At about 125K miles, I replaced air filter with a K&N, new OEM spark plugs and spark plug wires. The Tahoe has been running great and was getting normal mpg until recently. 15mpg in town and 17mpg on the road is what I normally get. The last 3 fill ups my mpg has been below 13.5mpg. Car still runs great but at 13mpg it's starting to hurt a little financially. Weather here in NC has been normal, my driving conditions or habits have not changed, etc. What could be causing my mpg to drop by so much while the suv still rides smooth and straight?

With the colder weather in the NE, I am experiencing lower mpg with the ES 300h. We have had several cold days here, and my mpg seems to be going down. My driving habits have not changed.

We bought a 2015 Corolla LE Plus this past weekend. The tank went from full to ¾ full after 38 miles of city driving. The onboard MPG calculator said it was getting 16 MPG (it’s rated 29 city/38 highway. When we took it back to the dealer the sales consultant said that’s normal – that it would improve after it got “broken in”. The car mechanic who I have taken all my Toyotas to and who has only worked on Toyota for the last 30 years says plus or minus a couple MPGs would be reasonable but not minus 13 MPG.
We drove it another 400 miles to “break it in” and during this breakin period it did get close to 38 MPG when we drove on the highway. Then I topped off the tank with gas, recorded the odometer mileage, zeroed out the onboard trip mileage recorder and the MPG calculator and my wife drove 61 city mileage. The onboard MPG calculator said it was getting 16.8 MPG and 61 miles divided by th3 3.854 that it took to top it off again = 15.8 MPG. Either way I don’t think the mileage should be this bad.

My 2000 outback wagon has only 67k miles. About a month ago, the check engine light came on. I took it to an Auto Zone and although unfortunately I didn't write down the code, the person who checked the car seemed to think it was probably just a bad tank of gas. I ran through that tank of gas and filled up with premium gas. Light didn't go off until THAT tank was near empty. Filled up a third time and light remained off until tank was near empty and it came on again. It has not yet gone off. I'm not sure how many more tanks of gas I should run through! The car isn't running poorly so I thought the bad gas was a good explanation.
A side note: about 6 months ago I had to have the head gasket replaced. I argued with Subaru and got some extra work done in exchange for the head gasket payment since my car missed the recall by a few digits but I was obviously stuck with an inferior product. I'm hoping they didn't do an inferior job. Even though it was 6 months ago, it wasn't that many miles ago - you can see my the year/mileage on my car that I don't drive a lot. Does that gas explanation sound reasonable? Anything about a head gasket related?

I recently purchased a new prius 2015. When I first got the vehicle and filed up it would say I had approximately 600 miles to go now it says I have approximately 400 something and I actually get a little under 400. So how many miles do you get let tank? Are they mostly highway or town miles? When you fill up how many miles does your car say you have? Also I was wondering how to actually get battery meter to ever say full I can never seem to get the last bar. And when I purchased the car they told me I couldn't go any faster then 15mph in ev mode but I actually can't go any faster then 8 mpg which kind of mashes the feature useless.

I just bought this car for my daughter. It's in very good shape; runs like a top. But the gas mileage is a lousy 20 mpg. All of my trips are local (no stop and go stuff as we live in the country). A buddy of mine with the same car and similar driving habits says she gets 25-28 mpg. So far I have changed the oil, oil filter and air filter.This can't be the best I can expect, can it?!

Having problem with corrosion of the tie down on a battery? The terminals are fine. It's just the metal plate that holds the battery in place with bolts. The paint has corroded off. I clean it up and cover it with dielectric grease. I have to do this every 4 to 6 months or so, because the corrosion keeps coming back. I had the same problem with my 2004 Subaru Legacy, and had to replace the battery holder as a result.

Our 2011 Subaru Outback 3.6R, which we bought brand new back in Feb ’11 and only has 4k miles, seems to be having issues with the cooling fan. The cooling fan will come on when the engine is cold and it will stay on the entire time the engine is running. I’ve read that the cooling fan will run the whole time when either the A/C is on or the vent control is set to defrost, regardless of whether the engine is cold or hot. In my case, the cooling fan comes on when the engine is cold, even with the HVAC off and it will remain running at full speed when the engine is running, again with the HVAC off.
Every time I go to start the car after it has been sitting for an entire day and the engine is cold, when I turn the key to the “On” position, before the engine is even started, the cooling fan comes on. How is this possible when the engine isn’t even running and the engine is cold. Again, the HVAC is off. Once the car is started, the cooling fan will remain on until the car is shut off. The fan is running as such a high speed you can hear it over the noise of the idling engine. Once I turn the car off the fan shuts off.
Since we’ve owned the car there were two other issues First, the transmission pan gasket wasn’t properly installed and it was leaking transmission fluid. That issue was fixed and is good now. The second issue was that oil was leaking from the timing chain cover. It turns out that the timing chain cover gasket was also improperly installed. This too was fixed, and doesn’t seem to be a problem anymore.

I purchases a 2012 Subaru Outback i2.5 Premium in January. The car has been stalling out after getting gas; I've put gas in it about 10 times, and it's stalled out or nearly stalled out after 4 or 5 of those times. The first time it happened I had to have the car towed back to the dealer. At the time, they thought it was bad gas, but the repetition of the problem has them stumped. There are no warning lights or error codes. I have had the car back to the dealer on four occasions, and unfortunately they can't replicate, find, or correct the problem. Now Subaru is involved. The car also runs rough and shifts rough, compared to the identical 2012 Outback I was given as a loaner the last time I had it in.

Where the heck is the gas cap release. Just bought it to get back home as the jeep needs broken motor mount fixed and had to leave it in town. The subaru is pretty beat up so the gas cap release could be hiding (as in handle gone) ?

I own a 2002 Outback. It is overheating. We have replaced hoses, thermostat, water pump, the temp sensor, had the radiator tested. Nothing has changed our problem. My husband is at a loss and the mechanic who has is now has no clue as to what else it could be. The mechanic is referring to it as a ghost problem.

I have a 2001 Subaru Outback with the 5 speed manual transmission. About 6 months ago the clutch went out and we had it replaced. We did not go to a professional shop and instead used a friend of my father-in-law who used to be a mechanic. Last weekend I drove the car on the beach to go fishing and got the car stuck in the sand.
After 2 attempts to get unstuck the clutch started smoking and blew out. I only attempted to get unstuck 2 times and was not "rallying" the engine hard. I realized I was good and stuck and stopped because I didn't want to spin the tires and dig myself so deep I couldn't get towed out.
My question is this; what are the chances that a brand new clutch would blow after 6 months? The car is used mainly to drive on paved roads to and from work and the grocery store. Both my wife and I have driven manual transmission cars for years and we don't ride the clutch. It goes through the usual wear and tear of everyday driving and yet, one incident that requires a little beef from the clutch and it blows?

I have a 1998 Subaru Legacy Outback (automatic) that has 176,779miles on it. I live in San Francisco and only drive the car occasionally every 2-3 weekends out of the city. Recently within the past month I have noticed that after turning on my car and once it is in drive for the first 10-15 minutes it has a hard time getting past 20 mph. When I put the foot on the accelerator to go past 20mph the rpm goes way up to 4, 5 or 6. Once it gets past this then car is smooth and I have no problems. This problem seems to go away within 10-15 minutes of driving or if I turn my car off and then on again it seems to go away. I called my mechanic and they said it could be that the transmission fluid is low. I checked the level and it is perfectly normal.
