I have the same truck as you but I can't recall if mine light up with dash when headlights are on or not. I will try to remember and look tonight.I saw this post about trying to reset the BMS, the flash brights/press brake pedal 3 times with key on but engine off did reset the bms-battery light flashed 3x, but didn't fix the radio knob light issue. Will try locking the truck for 8 hours,...
Here is that post, from September this year:

My truck is the work truck supercrew cab, love the truck but would like to get this working, hoping it will be a simple fix.
I haven't looked into the fuses yet-someone had looked at theirs and mentioned they were fine. Will check if the above doesn't work.
