I have exactly the same problem!  It has been working fine for over a year but changed on the 23rd of July.
I have compared similar journeys (my usual commute to work) and it started showing my MPG around half of what it was normally.

Looking through the rest of the data reported, I think the Fuel Volume Gallons figure is incorrect which will be used to calculate the MPG.

This is reporting about double what was actually used.  I wonder if there was a change made on the back end around this time?

I have a Diesel car.  Fairly certain I have the Automatic 2nd Generation (possibly 1st Gen!)

Have the same issue here, also a diesel car! MPG is about half of the real number. Checked the dashboard and the date for the change was July 27 (7/26 was still ok).
