No, not an issue. The air dam faults happen occasionally but it seems to fix itself almost all of the time. The other one is the infotainment system/sync. Very rarely it fails to boot so you just restart the truck or you can press 2 buttons on the steering wheel to force it to reboot. It failing to boot properly one time probably caused the code to come up

I would concur that it is probably nothing but…
I would reset the codes and see if they return!
