2023 Ford F-150 Lightning power train problems

“I purchased a used 2023 Ford F-150 PowerBoost on April 3, 2026. Within days, the vehicle began making a hard clunk during initial acceleration and when stopping. It also hesitates before accelerating, especially while transitioning between electric and gasoline operation. At times, pressing the accelerator does not produce an immediate or predictable response. The problem is worse when accelerating uphill. This creates a collision risk when entering traffic, crossing intersections, merging, or driving uphill. The clunk can be heard and felt through the vehicle. There is also a loud, high-pitched whine that follows engine speed and certain gear transitions and can become extremely loud at highway speeds. On April 22, a Ford dealer confirmed the clunk during acceleration and stopping. The dealer found excessive movement in the rear leaf-spring and shackle bushings and replaced them, but the clunk and hesitation continued. On May 11, the dealer confirmed the high-pitched whine, traced it to the Hybrid Drive Unit, consulted Ford’s escalation team, and replaced the unit. The whining, clunking, shifting irregularities, and hesitation remained and have progressively…”

“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.”

“The contact owns a 2023 Ford F-150. The contact received notification of NHTSA Campaign Number: 23V896000 (Power Train); however, the part to do the recall repair was not yet available. The dealer was contacted. The dealer confirmed that parts were not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact had not experienced a failure.”

“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.”

“I am reporting a safety-related transmission problem I experienced with my 2023 Ford F-150 equipped with the 10R80 automatic transmission. While driving normally, the transmission suddenly does not accelerate for up to 3 seconds while pressing the gas pedal, brakes either harshly or too soft at varying times, and very irregularly. This occurred while accelerating onto the highway, and almost every time I am braking at a stop sign or light, creating a potentially dangerous situation because the truck did not respond as expected when I needed predictable acceleration, propulsion, or deceleration. I believe this incident may be related to the known 10R80 CDF clutch-cylinder/sleeve problem. Ford technical information identifies axial movement of the CDF sleeve that can cause hydraulic-circuit leaks and harsh or delayed engagement and shifting. This condition can result in slipping, RPM flares, delayed engagement, unexpected gear changes, harsh downshifts, lurching, or loss of propulsion. This is a safety concern, not merely a transmission quality or reliability issue. Unexpected loss of propulsion or unpredictable shifting while merging, accelerating into traffic,…”

“I am reporting a safety-related transmission problem I experienced with my 2023 Ford F-150 equipped with the 10R80 automatic transmission. While driving normally, the transmission suddenly fails to engage then randomly shifts violently. This occurs when merging onto a highway, crossing an intersection, traveling at highway speed, stop-and-go traffic,creating a potentially dangerous drive. This is common issue with this type of transmission, mostly related to the drum itself; slipping thus causing its erratic behavior.”
