aeboi863 Posted March 22, 2014 Report Share Posted March 22, 2014 is it just me or has anyone else noticed lower fuel economy since ford has been doing updates to the cmax hybrid. when i first got mine in june 2013 i was doing really good on fuel economy just driving normal and then they came out with the update to let our cars go up to 82mph in electric mode well every since then my car has been achieving worse fuel economy and seems that doesnt use the electric motor for as long as it did when it had the original programming. Even seems that the engine runs longer while driving i live in fl and its pretty flat every where i go and i do the same 130 miles a day and before the update i always had great fuel economy over 41.2 consistently even 42.3+ on highway on long trips now i can barely ever get over 38 keep in mind during the hottest part of year i was getting the 41+ fuel economy then in september when ford has updates my fuel economy was good for a little while but then since then i have had 2 check engine lights for engine timer sensor running engine to long and even when i have almost a full battery and come to a stop light it will run the engine for almost a whole minute while stopped and then seems to slam the engine off or from time to time when going from park to reverse or drive it sounds like the motors or transmission are already engaged and makes very hard jerks on engine as im going in between park-drive. just wondering if anyone else has had any weird problems like thesethank you,mattsebring flwhite 2013 ford cmax with just over 36k miles Quote Link to comment Share on other sites More sharing options...

Sounds like something is amiss, I gained maybe one mpg with change on HWY. I wonder if they change % of Ethanol during winter in FL. For a test put in Pure Gas for a full tank and maybe injector cleaner see if that makes a difference. Might check air filter, changed mine at 40K, check tire psi, run mine at 49psi. and have 52K them going for 60K. Try to cover all the possibilities, it will be interesting if the Dealer comes up with anything. :) Paul C-MaxSea 1 Quote Link to comment Share on other sites More sharing options...
plus 3 golfer Posted March 23, 2014 Report Share Posted March 23, 2014 What Paul says. Do you know what the diagnostic trouble codes were for the check engine lights? They should be on the service order. ptjones 1 Quote Link to comment Share on other sites More sharing options...

homestead Posted March 24, 2014 Report Share Posted March 24, 2014 I get about the same mpg on the highway and about 3 mpg better in the city, especially on shorter trips.So for us the update was a plus. Noticed that with the temperature rise the last month or so the cmax mpgtracks the temperature pretty close from 38 - 60 degrees F. For example temp today was 60 degrees F and mpg in a9 mile city trip was 60 mpg. C-MaxSea 1 Quote Link to comment Share on other sites More sharing options...

JohnnOhio Posted March 24, 2014 Report Share Posted March 24, 2014 Sounds like you have the same problem I was having. The ICE didn't seem to be putting power to the wheels. It was like driving in a car with the clutch slipping. The engine RPM's are up but your not going anywhere fast. The reinstall fixed the problem. My dealer stinks. I only chose them because they were close. I ordered mine and had to pick a dealer to deliver to. Now that it is fixed I have been driving 35 miles to another dealer that really seems to have they're act together. Kind of sucks putting 70 miles on the car to have an oil change but I'll never go back to the first dealer again. Quote Link to comment Share on other sites More sharing options...
aeboi863 Posted March 28, 2014 Author Report Share Posted March 28, 2014 (edited) well my local dealer said they would flash/download the computer update but cant do it till one day next week and yesterday i had a check engine light for engine coolant temp that i asked them to pull before the computer erased it. i had drove my car before this light came on for a few miles in ev mode at 35 mph and have no idea why it came on. im really wondering if i need to lemon law my car. i have the dealers print out of all services/warranty items that have been performed on my vehicle since i bought it 8 months ago and i have a total of 19 pages of repairs. it was made mar of 13 and i bought it jun of 13. i just dont know what to do im so confused because i love how much money my cmax saves me in fuel every month i went from my 01 blazer at 1200.00 a month in fuel down to just 350+- the only other vehicle i would possibly think of would be a diesel jetta but would rather wait till they came out i think next year with their new diesel engine or the diesel mazda 6 if it ever hits the USA i know they say it will be here but when?

joc Posted December 3, 2014 Report Share Posted December 3, 2014 I recently purchased a 2013 C-Max that was on a dealer lot since last year. It only had 300 miles on it and they made me a pretty good deal so I pulled the trigger. I was trying to determine if the fuel efficiency update has been performed on my vehicle (13B07.) Is there any way I can figure that out without taking it back to the dealer? I bought the car out of town and would like to avoid driving back if possible. Also, is there a general consensus as to whether the update is a significant improvement? Pros? Cons? Quote Link to comment Share on other sites More sharing options...
