Ford Dealer STUMPED...REFUSES WARRANTY!! (Part 1 - Intermittent Charging System MALFUNCTION)

Owner of this 2021 Lincoln Corsair EcoBoost reached out to PHAD because the local Lincoln Dealer has been unable to repair a VERY intermittent Charging System Problem that has been plaguing this car since DAY 1. The car only has 25k miles! The issue has occurred a total of 12 TIMES over 3 YEARS...WOW...how am I supposed to reproduce the customer complaint?? MISSION IMPOSSIBLE! "U012D - Lost Communication with Alternator" is stored in memory. It has been to the dealer 4 times over the last 3 years, and is STILL BROKEN after several parts cannon attempts... They replaced the Active Grille Shutter...TWICE! Owner had no choice and started a BUY BACK request, but got DENIED by the dealer, stating that the car was over 3 years old...Crazy!! Owner's wife loves her Lincoln...can we save the day and diagnose a weird issue that happens ONCE EVERY FEW MONTHS?? I don't have high hopes, but let's follow Standard Operating Procedure: -Research the Charging System -Make a GAMEPLAN: test the LIN BUS wiring integrity from the PCM to the Alternator Will the Diagnostic Plan yield any interesting results?
