I have found one issue with the "new" Jeep Wrangler. This is a 2007 Wrangler X with 87k miles. When I cycle through the display, the AVG ECO screen does not display any numbers and the DTE screen always shows 255 miles left regardless of how much fuel is in the tank. The rest of the displays like Elapsed Time and the regular and trip odometers function as expected. But it's like the trip computer doesn't know how much fuel there is though the fuel gauge appears accurate.
