Odometer not reading mileage & trip not registering distance

Cstringer · February 7

I’ve got a 2020 gmc sierra 1500 Denali w/6.2. Few weeks ago the odometer quit reading on the dash, just displays “- - - - - -“. The distance on the trip screens do not register anything.
when I unlock the truck & open the driver door the dash lights up and the odometer does display, but after a few seconds it goes back to the dashes.

also flashes warning on dash to program cluster both of these came up issues around the same time.

any idea on the fix for this?

Are you using the MyGMC app? If so, is the mileage still showing on the app?

Did you ever find a solution for this?

I did not find a solution to this. It doesn’t seem to affect anything. I’m dreading calling the dealer to ask. I have seen one post of someone asking about this same situation happening on an HD truck. He said the only solution the dealer presented was to replace the gauge cluster.
