I programmed the middle of the dash to display the vehicle speed, and noticed today while on the highway, the analog speedo is exactly 5mph faster than digital read-out? anyone else experience this? I have the stock Rubicon 33s.

Probably not an apples to apples comparison, but my sport is spot on no matter the speed.

Do you have a GPS or phone to compare them to see which one is wrong?

Mine is spot on digital vs. analog. I checked them both against each other and against hand held GPS today.

so went to test today with phone, and both digital read-out and analog speedo gauge are now reading the same, go figure?? I know yesterday I accidentally switch it to KMH so maybe switching back screwed up the syncing between the two. The digital readout and cruise are spot-on according to my phone. I got use to the digital read-out in my other car where it is more critical to use the the analog gauge is in 25 mph increments and trying to determine the speed. between 50 and 75 mph is very hard to do....

You left out that tidbit when you did your original post. Daaaah, that will do it... cause the discrepancy.

I had the same issue. My tires on JLUR came over inflated. I let out 5psi on each tire to make them 37 and now the speedos match.

****fake news. Still off just closer than before. :(

Mine was about 1mph off for about 500mi then today noticed it was about 3mph off at 50mph. Hopefully it will change back eventually.

Some dealers are shrugging it off as normal saying the speedometer is just an estimation. Pretty hilarious because the problem is intermittent in that there are times when it's spot on and others when it's off by over 5km/h.
