Warranty denied, mileage too high! JK, There was a thread a while back about a couple of individuals who had defective instrument clusters. Charge your batts, just to make sure it isn't one of the ESS batt gremlins.
My wife’s 2.0 Rubicon does it too so it’s not the batteries, been doing it for awhile. I call it the Herman Cain tax plan may he RIP, it usually does it on start up and will revert to the correct mileage when it clicks over the next mile.
