2014 mkz 2.0L fuel economy gauge bug?

[c-plus]

For 2013/14 2.0 or 3.7, anyone notice the fuel economy bar almost never moves while you driving?  The bar is supposed to move up and down depending on the amount of fuel is being used at that moment.  The only bar that really works is the average per litter/mpg.

I believe this gauge records average fuel economy, and not instantaneous. The longer you go without resetting it, the less it will change.

I'm sure the gauge shows both, average and instantaneous.  The reason is, the bar (not the one showing the average with number) jumps up and down when you traveling about 20-30 km/h.  If you're in US, you are using MPG, which means the bar is always down.  That's why you don't notice it's there.  If you are using L/100km, the bar is always up, and does jump up/down sometimes when traveling at low speeds such as 20-30 km/h.  See pics attached.

I drove a 2.0 ecoboost that showed the graph in MPG mode. I have the 3.7 FWD and in MPG mode i only see a white line near the zero on the scale. Shouldn't it be correcting for units when the units are changed to MPG?

 

The eco boost model was actually displaying instant MPG on the scale between 0 - 40 depending on the amount of gas I was providing. 

 

I changed the units on my mkz to L/100 km and noticed the full length white bar when idling - which is technically incorrect considering i am sitting idle and my instant mpg would be 0 (irrespective of the units)

So I took my car to the dealer today for the fix on the Temp, Instant MPG bug and Vehicle report "Data Collection Fault" and in return I was given a 2014 3.7 Z as a loaner.

 

In this vehicle, the Temperature display is present next to the car odometer reading and the instant MPG bar graph (white) goes up and down based on relieving and applying gas pedal, respectively.

 

When I showed it to the Tech, he said that the early batch of 2014 Z have been coming in regularly for software reprograms due to improper module activation during the build stage. At this point he did not have a clue as to why this was happening and it seems that all the bugs in my car may be "fixable" with a software refresh and/or update.

 

Will keep posted when I hear something.

Posting an update:

 

The dealer finally got back to me after 8 days saying that there was a TSB out for MKZs manufactured between Oct 13 and March 14 regarding guage cluster re-programming. 

 

I picked up my car today morning and the instant MPG readout is now functioning as expected. 

 

Also, for owners who use the "snapshot device" from progressive, it is not completely compatible with the SYNC system and you may lose functionality like VHR and NAVIGATION. The simplest fix for this is to do a master reset after you remove snapshot from the ORB port, when you are done. 

 

They still do not have an answer for the missing temperature readout in the cluster. Their current response is that it may not be available on the 14s. I do not believe them as I already drove 2 2014 Mkzs (one 2.0 and one 3.7) and both had the readout for temperature in the cluster.

Thanks for the info.  I'll get mine done the next time I take it in.
