Does anybody know if a weak or failed accessory battery affect mpg? I noticed my mpg suddenly dropped from around 46 to around 41 over the past several months. I have owned my ford fusion hybrid 2013 for 3 years in florida and have the same driving patterns, but could not get an answer from the ford dealers. They blamed it on more ethanol in the gas. I researched that and could not find anything on that. I was in for an oil change and asked the dealer to check the accessory battery because my car would not stay in accessory mode listening to the radio before turning off. They found a bad cell in the battery and had it replaced and low and behold, my mpg has jumped back up.

I just bought a 2013 ford fusion hybrid last week and so far my mileage is quite good. I left the dealer registering at 19 avg and it is now past 42 and climbing. My trip meter is even better since I tried it once over the past couple days and it is registering over 47mpg. I drive differently than the way I drove a gas version but I keep up with traffic and anticipate lights. i get most of the regen energy also. The car is extremely quite and smooth. When driving down the highway I rarely notice when it switches between ev and gas.

Just bought the 2013 ford fusion hybrid last week. I was very worried that I would not get the mpg because of all the discussions of not getting anything close to the sticker mpg. My fusion started out with 19mpg off the lot and is now at 42.2 and cliimbing. I also set a trip and I am getting over 47mpg
