If it's any help, I have a summer 2022 140 9 speed auto, which does not have U connect, but a pioneer radio, where all adjustments are made via the steering wheel controls. I have never had any problems with the mpg readings at all...our dash display shows no current fuel [instant mpg] on dash display does however show some random letters or emblems this is uconnect syst and the radio screen will display the readings [dont look correct though] fiat have now spent several weeks trying to resolve this on our new van. interested if anyone has or had same problem
thanks glyn
I do have ongoing problems (since 3 weeks ago) where the driver assist systems continually but intermittently, shut down and restart. As I am in France this is something that I am living with until I get back to the UK.
