So, I bought our '16 V after it had sat on the lot for a couple of weeks. After purchase, the mpg display stuck on 44.2 for a few weeks and then started working again. Fast forward to the present, and after returning from two weeks away, same issue, same mpg. Thoughts? Thanks.
how long have you owned her, and how many miles? first thought that comes to mind is the 12v battery.
What is the display at? Trip 1, Trip 2, ? Have you played with the disp settings on the steering wheel?
