2023 Ford F-150 Lightning electrical system problems

“The high-voltage battery in my Ford F-150 Lightning is exhibiting significant degradation and erratic power availability. The vehicle will no longer charge above approximately 60% state of charge. Upon startup, available power can suddenly drop from 100% to approximately 50%, and the indicated available power continues to fluctuate unpredictably while the vehicle is being driven. I am concerned this condition could result in an unexpected reduction or loss of propulsion power while driving, creating a potential safety hazard. Car is scheduled to go to dealer on 10/8/2026.”

“On August 20, 2026, while driving my 2023 Ford F-150 Lightning, the vehicle suffered a sudden, complete, and catastrophic loss of propulsion. The truck stopped abruptly while in motion on an active roadway. This immediate loss of power created an extremely hazardous situation, exposing myself, my passengers, and oncoming traffic to an immediate risk of a collision. The vehicle was towed directly to Williams Ford of Binghamton (Vestal, NY), where technicians diagnosed the issue as a major component failure tied to an outstanding manufacturer safety recall. Ford recall 24S12 Positive HV battery junction box. The vehicle has been grounded at the dealership for over a week awaiting replacement safety parts from the manufacturer. This unexpected, abrupt stop constitutes a severe safety risk that renders the vehicle dangerous to operate on public roads.”

These temps made a battery fire a significant possibility putting myself and others on the road around me in danger. The car is at the dealer in Hays, KS being looked at. There was no indication on the dashboard that there was any problem. According to information I have uncovered, these temperatures are over 3x the safety limits specified by FORD.”
