First reported the problem of not getting 50 mpg to the mechanic at our first oil change. We were told that it takes a bit for the battery to break in, etc... Well not we have about 44,000 miles and we still cant seem to get more than 36-38 mpg. Most driving is done in the City and this is the same mileage that we get when we travel on Interstate 5. I really feel like we were lied to. I just heard about a possible class action lawsuit. I thought that I would share. https://www.chimicles.com/honda-accord-hybrid-mpg-class-action-lawsuit

We were impressed with the advertised mileage of 'up to' 45 mpg Highway and 50 mpg City with an average of 47 mpg. We knew we wouldn't get the promised maximums, but we didn't realize we would get OVER 20% LESS. The first month we averaged 47 mpg - we were overjoyed and telling our friends! The second month it dropped down to about 42 mpg. We were still impressed, and would mention it if asked. The third month it dropped to about 35 mpg where it has been through the current mileage of about 8,000 miles.

We don't brag anymore, because there are other cars that can get this same mileage without the electric motor and the battery taking up half of the trunk. We liked the thought that we were using less gas and creating less carbon emissions by purchasing this car, but now, since the savings on gas is not as expected, we are worried about the huge expense of the eventual electric motor battery replacement.

PROBLEM: POOR FUEL MILEAGE

The problem is that I am experiencing significantly poorer mileage now than when I first purchased the vehicle. I purchased this vehicle in large part due to its reported EPA mileage of 47 MPG Highway/50 MPG City. I use this vehicle for business purposes and have kept meticulous gasoline purchase and mileage data since acquiring the vehicle in late April of 2014. Through mid-August of 2014 (first 3-1/2 months), I averaged 50 MPG. With no change in driving habits or distance, my mileage then began to drop off to an average of about 47 MPG through early November 2014. As the weather got colder, mileage began to drop off significantly, averaging 42 MPG through early December and now about 38 MPG through the month of December. In eight months, I have put 20,000 miles on the car.

My Honda dealer has offered no viable explanation but encouraged me "to bring the car in" during a weekday (which is highly impractical) for an evaluation. The dealer did offer two possible explanations, neither of which I consider plausible: one, that I should be purchasing 'Tier 1' gasoline as recommended for the vehicle (Shell, Mobil, Exxon or BP); and two, that 'gasoline producers change their formulations for winter,' resulting in lower mileage. While I cannot dispute the second issue, I have been purchasing other-than-Tier-1-gasoline (predominantly from Sam's Club or Wawa) since purchasing the car in April, managing pretty well for the first few months. I believe the cold weather performance of the lithium-ion battery and Atkinson engine are prime suspects. Also, the car's internal cabin heating system is all electric-resistance, significantly impacting battery capacity for drivetrain use. As a result, I have been switching the heating system off and driving to and from work in a cold car to avoid even poorer winter mileage.

This is a serious problem, as Honda's reputation is on the line. I purchased a vehicle advertised to achieve 47 MPG that is now achieving, at best, 40 MPG. While I don't challenge the accuracy of the EPA mileage estimate, I hope that future buyers of Honda Accord Hybrid take into account my real-world experience - so as not to be as disappointed.

When I purchased this car, I had the dealer install the Honda HFP 19 inch wheels with Continental ContiSport 3 235/40-19 summer tires and was told that these tires would impact my gas mileage. So I put back the stock wheels/tires and still I only average 38 mpg. I am SEVERELY disappointed in the mpg this VERY expensive car is returning to me. I think Honda should come clean with the REAL WORLD mpg this car is supposed to get. I see on Edmonds.com that many people report getting 45-50 mpg which makes me think that there is a sub component that is not up-to-par on some of these Hybrid cars. Actually, Honda is quoted as saying that they are building some 336,000 Hybrid Honda Accords for 2014 but have only been able to make 3600 because of "parts shortages" from their sub contractors. This really shouts "sub-standard parts" to me and I will bet money that a recall is in the works. Time will tell if I over paid by $10,000 for this Hybrid technology. Hope not though because the car really is a quiet driving car. And don't get me started on that Honda Infotainment system....

My "Hybrid is supposed to achieve 45 MPG Highway and 50 City, 47 Combined.... We manage a wonderful 34 highway and an Average of 35.3 for the first 1450 miles. When you turn the car off, it gives you a score on your driving technique for increased MPGs... every time it shows a full score. 5 Fully branched trees.. The car is on it's FOURTH (4th) tank of gas. We have placed 13+ gallons at each fill. The range after fill indicates 587 miles on a 15.8 gallon tank? The car knows it's only going to get around 37 MPGs...

35.3 is 21.5 % lower than the Highway estimated rate.
