Headlight Gremlins
My dash threw a Headlight Service warning at me after 3000 miles. Didn't see any thing wrong. Message said "Headlight Service needed Check owner's manual" Not much there. Turned every thin off then back on . Message gone. I have the HID option. Anyone else seen this?
There are no HIDs in 2021 F-150s, but it's tough to say. The truck has light burn out detection, and some faults can trigger incorrectly if the module responsible doesn't get a response in a certain time period, which can be caused by the vehicle network just being busy. If you don't see any light issues, I would just move on.
