System, Parking, headlight malfunction warnings - 24’ OR Non-hybrid

[wongaust]

Taking to dealership on Tuesday. Driving through mild rain today for approximately 3 hours. System, parking and headlight malfunction notification came on. I tried negative battery disconnect for 30 min but issues persisted. Pulled codes from OBD and only had loss comm with BCM (U014087). Clearing did not resolve. Anyone with similar case? If so, what was outcome of dealership visit?

Vehicle drives perfectly fine except no driver assist features, powered tailgate doesn’t work, vehicle doesn’t register key fob, wipers intermittently works

Currently have 17k miles.

Question, have you added any lights or done any electrical work to the truck?. If you haven't, it sounds like one of the electrical sensors on the bumper., or Leveling kit

Thanks for the response! No mods to vehicle - no added lights nor leveling kits.

Possible since you have a '24 (like myself) that you have the grille shutter that has the poor connection and is getting water inside it, causing a short.

Was there a tsb for this by any chance that I could reference?
