Drive shaft/ Drive line noise concern with being disabled. Dealer confirmed noise states "repair under review"

While driving North on I79 in dayligh I attempted to engage adaptive cruse control. The indicator lights on the dashboard were too dim to be visible and I was unable to tell if cruise control was on or determine what the speed setting was. After successfully engaging the control using buttons on the steering wheel the truck began accellerating strongly. I was unable to tell what the speed setting was but it must have been in excess of 80 mph as I had to turn the control off at that point. I returned truck to dealer and was told that lack of brightness for this indicator (and several others, such as turn signal indicators) was a design issue and could not be repaired by the dealer. I have tried every remidy I could find, even had the dealer's sales person take pictures of the dash while driving to verify the issue.
