salsaguy Posted May 13, 2013 Report Share Posted May 13, 2013 hmm interesting and quite possible if Ford used 2 different suppliers for a key part of the engine or system that directly affects fuel econ. Quote Link to comment Share on other sites More sharing options...
fotomoto Posted May 13, 2013 Report Share Posted May 13, 2013 Although his location isn't given, his review is from February which could mean his first car was driven in very cold conditions. Too many unknowns. Quote Link to comment Share on other sites More sharing options...
jmckinley Posted May 13, 2013 Report Share Posted May 13, 2013 (edited) But, if this is real, it is really interesting. First, it's amazing that a dealer would buy it back after only 1,000 miles. Everyone else has just gotten the "needs more break-in", "you're an idiot and can't drive a hybrid", "it's too cold", etc stories. Soon it will be "it's too hot, don't use your AC so much" Second, there may be some truth to this. On this forum there are multiple reports (mostly recently) of new owners getting great mileage off the first tank and only improving after that. Others, like me, can't break 40 no matter how dorky I drive. And, mine spent from 2500 to 4000 odo miles in the south with mild temperatures. Did something change between the first builds and now? Maybe. I've complained every time I've taken mine in, hoping that there is a secret fix they're not talking about. No results yet. If the good mileage requires driving real slow and not using the heater or AC I might as well have my old '68 VW back. It got great mileage but was slow and the heater didn't work and there was no AC. Edited May 13, 2013 by jmckinley Quote Link to comment Share on other sites More sharing options...
HotPotato Posted May 13, 2013 Report Share Posted May 13, 2013 Innnnnnteresting... how could we find out if different firmware etc is used from one build to another? Quote Link to comment Share on other sites More sharing options...
Jus-A-CMax Posted May 14, 2013 Report Share Posted May 14, 2013 (edited) I sense that Ford has improved something internally with the CMaxs, just comparing my MPG experience with that I am seeing now. Right now, we are seeing a slew of high MPGs and more :happy feet: 600 Mile CMax Club Members :happy feet: and looking at their odo, they are just starting to break in their engines. I can't recall getting these great MPGs even with my temps here in SoCal - ALL FOR THE BETTER though :rockon: & :drool: Whatever Ford has done (if they did it), I wish they would pass it on to the early adopters as well.

Edsel Posted May 14, 2013 Report Share Posted May 14, 2013 Would be nice if this was some sort of software update!

fotomoto Posted May 14, 2013 Report Share Posted May 14, 2013 Whatever Ford has done (if they did it), I wish they would pass it on to the early adopters as well. IIRC, we've had at least two owners have their original C-maxes totaled from accidents and get another one (hippie-mom and ?). It would be interesting to know if they have seen any big differences.

orphoto Posted May 22, 2013 Report Share Posted May 22, 2013 I was having issues with the window unrolling problem early on and Ford decided to reflash at least a portion of the internal software. Immediately afterwards i got about 1.5 mpg increase in fuel economy. Bought my SE in October so it was one of the early production models and the reflash took place in about January.

That could account for the sudden increase in mpg. Quote Link to comment Share on other sites More sharing options...
orphoto Posted May 23, 2013 Report Share Posted May 23, 2013 Hi Homestead. I think it did reset the trip readouts, but not the lifetime. I track mileage tank by tank, and noticed a change in the way the engine reacted to driving situations and the actual at the pump mileage bumped up roughly 1.5 mpg.

KAL Cmax Posted June 4, 2013 Report Share Posted June 4, 2013 I just bought my Cmax in May, built Sep 2012. I do not have the latest software installed (the hybrid info on MyTouch looks interesting). I have yet to have a battery issue and on my first full tank of fuel averaged 46 mpg. I do live in MA and the weather has nice also.I have read alot of issues blaming on early builds, not sure if this is considered under that. This is my first hybrid too.
