Hopefully they can find the problem or help out with replacing the vehicle without any cost to you. This would drive me nuts since I would be expecting great gas mileage with a Fit.

I am sure the dealer checked all the items below and you did not indicate any of these symptoms.

Reasons a Car Is Burning More Gas Than it Should

Saving money by improving gas mileage.
An unexplained increase in fuel consumption by your car costs you money and is a symptom of potentially expensive problems. Identifying the reasons your car is burning more gas than it should and correcting them will save you money and help you to avoid costly repairs. Familiarizing yourself with the more common causes of poor fuel economy is a smart way to help keep your car running as economically and efficiently as possible.

1. Fuel leaks
   
   
   • Fuel leaks can cause a sudden drop in fuel economy and create a potentially dangerous fire hazard. You should suspect a fuel leak if you smell a strong gasoline odor near the vehicle or notice unexplained wet spots on the ground underneath your car.
     
     
   Dragging brakes
   
   
   • Brakes can malfunction, causing a condition where they do not fully release. This increases the load on the engine, forcing it to work harder and burn more gas. Suspect dragging brakes if you notice excessive gray dust on wheels and tires, or the accelerator must be depressed farther than usual to achieve normal driving speeds.
     
     
   Vacuum leaks
   
   
   • Vacuum leaks cause a car to burn more gas than it should by introducing excessive air into the engine, unbalancing the fuel to air mixture. The engine compensates for this uneven fuel to air ratio by introducing more gasoline into the mixture to compensate for the increased air volume. A vacuum leak will typically cause rough idle, poor acceleration and misfires at operating speeds. Cracked hoses, worn out gaskets and loose fittings are common causes of vacuum leaks.
     
     
   Clogged air filter
   
   
   • Air filters trap dirt particles, preventing them from entering the engine. Over time the air filter will become clogged with dirt particles, reducing its ability to allow the free flow of air into the engine. Symptoms of a clogged air filter are burning more gas than normal and poor acceleration.
     
     
   Worn spark plugs
   
   
   • Worn spark plugs reduce an engines ability to burn all of the gas in the combustion chamber. Some of the gas remains unburned and is expelled into the exhaust. This reduces power, causing the vehicle to use more gas to do the same amount of work, lowering fuel efficiency. Worn spark plugs cause misfiring, reduced power, poor acceleration and reduced fuel economy.
     
     
   Underinflated tires
   
   
   • Tires that are not fully inflated increase resistance to rolling, requiring more energy to move the car forward. The engine has to work harder to overcome this increased resistance, resulting in the car burning more gas than it should. Tire inflation should be checked regularly with a tire pressure gauge and kept at the manufactures inflation specifications.
     
     
   Driving habits
   
   
   • Aggressive driving, jack rabbit starts, exceeding normal speed limits and excessive idling increase fuel consumption and should be avoided.
     
     

 

Do you weigh 800 lbs or something?

 

Out of all those things I suppose I would look at the brakes.

We know it's not a fuel leak, because the dash MPG gauge wouldn't account for that, that would also eliminate siphoning, besides that he said it's garaged. All the rest should be non-issues if the car is well maintained by the OP, and it only has 39k miles.

ECU issue? I would assume if it were having any major engine or sensor problems it would be throwing codes but maybe it's not communicating, in open-loop, or something like that? I would think the first thing they would do at the dealership is hook up a scanner, so idk.

 

Nope. There's no way. Its in garage always. I'm the only one with access. I'm positive of this. I have surveillance cameras cause all my tools. Trust me. Lol

 

Yeah I've pondered the ecu thing. I mentioned it to them before to update and or reload the fuel maps and whatnot but they said it checked out. Its a head scratcher at this point. But Honda's sending some bad ass mechanic to assess it and see if he can fix. If not we sit down to chat was they're words. Idk well see. I don't care if they lemon it, I don't want no money, I don't care what happens as long as its fixed and if it can't be then replace the engine or the car or something. I'm usually good at figuring this stuff out myself and it erks me I am stumped on this one . lol

 

186lbs pal!

 

I'm getting 23mpg but I do have a heavy foot lol

 

Since the car was drop off yesterday at the dealer according to the first post in the thread would be interesting to find out if the dealer was able to resolve the issue?

 

Since the OP said that he/she bought the gas from the same station and even the same pump. isn't it possible they are continually buying crap gas? Try a different station.

Don't ever forget about the KISS rule.

 

Nobody siphons 3 gallons at a time.

I'd agree- it's stupid advice to tell you to keep buying gas at the same pump. If anything that's not eliminating a variable but adding one, unless you know for sure the pump is properly calibrated.

I'd say disconnect the battery just on the off chance that something got weird in the computer and it's not running right.

And that if the dealer sent you out to buy more gas a few more times he's really just trying to get rid of you.

 

Postponed till weds.

 

No dude. No. I have never bought gas at same pump or station. This is a procedure Honda does when a car is doing what mine is doing. As far as the kiss rule goes .....I live it! Literally! Lol

 

Batteries been disconnected before and ecu was checked. It was not the issue. The dealers not trying to get rid of me , theyre the only ones willing to help. The one i bought it from is incompetent. Lol Honda's saying its prob the motor itself at this point. I'll find out when they lmk. I've mentioned alllllll of this already guys. Thanks for the help tho.

 

Given that you have come from a previous Fit that was getting better gas mileage, I think we can more or less eliminate overly aggressive driving (normally the reason for this issue!)

I am going to go with one of two things (plus a third). 1) It's possible the gas station you are going to is overstating how much gas you're getting. Basically, scamming you. Or the shutoff on the gas pump is kicking in too early. If you're going to many stations, this isn't it. 2) Dragging brakes. Yes, it could be elsewhere in the drivetrain but this is the most likely area. Also, this is very unlikely, but do make sure your foot isn't slightly overlapping the brake.

And the third possibility I think, is that the car does indeed have something more seriously wrong with it. I would keep communicating that you would like to solve the problem, but you're willing to exchange it for a different one if you have to. That should help keep the dealer on the same page as you, but honestly, their incentives aren't exactly the same as yours - the seller hates the idea of a lemon. And yes, that is a rare outcome, but it does happen.

Such a low fuel economy is only "normal" for an extremely aggressive driving style, which you don't seem to have. So I would say that mpg is not normal.

 

Exactly my thoughts as well. Yeah I'm not loyal to any particular gas station. I use whichever I need. Gas pump scamming me was a thought bit the math checks out and I generally go to too many diff stations for gas. Only reason I'm going same one same pump is Honda directed me to do so. The rep from Honda said there was a few cases of aluminum shavings left behind on accident in some engines resulting in scarred cylinder walls not enuff to kill the motor but kill its performance resulting in poor fuel economy. It was accords and civics so far tho. No fits yet that he heard of. Idk I'll see what they say. I just want it fixed or replaced. I don't really care which.

 

24mpg is the average for the life of my 09. You are not alone. I have blamed my aggressive driving. But I have to wonder...what mileage do other 09 owners get on one tank of gas if they drove aggressive.

 

I'm thinking sticky brakes or something like bad spark plug gap? Or a coil problem?

One way to tell if it's sticky brakes is to take two similar cars to the top of a hill and just let them roll down... there will be some differences due to tires but they should be close, I would think.

 

Soooo...just to update...car is at Honda as of 3days ago! Finally! Haha called today to ask about its progress and after three days they say they're still running diagnostics to try figuring it out cause so far they're stumped as to what it is causing this. They aren't denying it, they in fact have confirmed it. Honda north america gave me a case number again and said if they can't fix the problem then its arbitration time. I don't know what's gonna come of this but like they said when I called its not looking too good for my fit. So now I'm stuck waiting and wondering what they're going to do about it if its unfixable and deemed a lemon. Any insight into it, or the arbitration process from anyone that's been through it?

 

Man this process is taking forever! Lol

 

I get generally 500km to a full tank on my GD3. Please tell me im about average.
