Driving home from work the check engine light came on then I received a message through my phone app regarding possible issue with ABS & to stop driving it light comes on.  Brought it in the dealership the next morning.  They called me in few hours that Code: 20-NA-155 appeared.  Basically, break system control has a bug and new coding calibrations are available.  Long story short, this is not covered under warranty & was $250.00 out of pocket for me to have the tech update the computer.  How is this not covered under warranty since it is their internal programing issue?  Thoughts, anyone have this issue?  Did the fix work.  Have had the truck for 3 years now with no issues prior.  Ballentine attached for this code.
