2023 FORD F-150 LIGHTNING BEV Power Train Problems

The front traction motor on my 2023 Ford F-150 Lightning failed without warning, causing the vehicle to lose all-wheel drive capability. The truck automatically limited available power to about 67%, which I later learned indicates the front motor was disabled and the vehicle was operating in rear-wheel drive only. The failure occurred with no warning lamps, messages, or prior symptoms on the dashboard or in the FordPass app. I assumed AWD was functioning, which could have caused a serious accident in snow, ice, or gravel conditions because the loss of front-wheel traction significantly reduces vehicle stability. The component/system is still available for inspection. At this time, the issue has NOT been reproduced or confirmed by a dealer, and the vehicle has NOT yet been inspected by the manufacturer or any other party. Cause of failure is UNKNOWN. This lack of a warning or alert to the driver represents a major safety hazard because it changes how the vehicle handles without the driver’s knowledge.

I was leaving my storage unit on Sunday October 6, 2024 at around 7 pm. I was traveling at 5 mph as I approached the exit gate code box. I stopped at the top of the steep hill by depressing the brake. I rolled down the window so I could put the code in that opens the rolling gate below. As I took my foot slowly off the brake, suddenly the vehicle rapidly accelerated, veering slightly left, the steering wheel locked as I pressed the brake pedal twice more it was unresponsive. We flew like a rocket ship knocking down small trees, 2 light posts with 1 light coming down and breaking passenger side windshield. Continuing crashing through 2 iron water main fixtures and through an iron gate. At the bottom of the hill the truck flew into the air and came to a hard landing, the steering wheel unlocked and we came to a stop quickly as the one pedal finally engaged and the computer screen announced " one pedal engaged". Then announced Power Train Malfunctioned. Also airbags never deployed. Prior to the wild ride, the vehicle was awaiting the overdue WiFi update named Power Train system update and prior to approaching the hill, I had tried twice to turn on the one pedal and got the never before seen message " one pedal failure could not engage". Truck was a total loss and my passenger and I were injured. When I contacted a Ford representative and told them about the incident, I mentioned that there was 2 other incidents of a brief steering wheel lock and rapid acceleration without injury or crash, I was told that I should have brought it in, therefore they were not responsible. The 2 brief incidents left me unsure of what had happened so we thought it was a fluke and without out any computer warnings we paid it no mind.

I made a left-hand turn during a snow storm, and the right rear wheel slid and I made contact with the curb at a relatively low speed. The rear right wheel assembly failed and snapped, leaving the wheel assembly 90 degrees to normal. In other words, the wheel went from vertical to horizontal. Upon visual inspection, the axle snapped, and the axle's interior steel looked defective. The axle appeared very coarse, porous, and poorly consolidated. I requested to keep all the parts which are now located in storage. Both the insurance company and the Ford Motor Company dealership seemed to think the axle was defective. Nobody was injured or hurt.

Powertrain Failure. Vehicle unresponsive. Multiple complains through various individuals of this failure. Battery pack failures causing numerous safety issues related to driving, 12v system, etc

On my new Ford F-150 Lightning, five out of the six studs on the right front wheel sheared off, leaving just one lug nut and stud holding the wheel on. I took my truck into the Ford dealership who repaired the vehicle and it was returned to me. They did not appear to be escalating the dangerous situation to Ford. The dealership kept the removed parts for warranty submission.

“Powertrain Malfunction/Reduced Power” error message with accompanied vehicle propulsion reduction to approximately 5 mph.

While driving in sport mode multiple times, received "drive mode not available" message. Vehicle reverted to normal mode changing expected regeneration braking force. No other issues with the vehicle noted or stored in CAN. Seems to be a software glitch but arrives randomly and unexpectedly changes expected regenerative braking force requiring more driver input.

The contact owns a 2023 Ford F-150. The contact stated that while driving after a cold start or after stopping at a traffic light, whenever the accelerator pedal was depressed, the vehicle started losing motive power. The contact stated that the "Wrench Symbol” was illuminated and the message "Powertrain Malfunction/Reduced Power - Contact Dealer" was displayed. The contact had taken the vehicle to a local dealer, who diagnosed that the gear shift module needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure. The contact researched online and related the failure to Manufacturer Communications: Battery Electric Vehicle (BEV) High Voltage Battery Module Replacement Program Number: 23H01 (Electrical System). The failure mileage was approximately 2,300.

Mileage: 2,300

While driving at high way speeds, a fault in the drive train was detected and reduced power to the electric motors, reducing our speed to only 5 MPH.

Jan 9, 2024 Aprox 465 miles Powertrain malfunction/ reduced power (15 miles per hour) Vehicle was on the dealer shop for 8 days...at the time of returm 9f the car they told me that the issue was fixed

Aprox 1083 miles PowertraiN malfunction/ reduced power Vehicle was on the dealer shop for 4days so far( still counting)...second time on a brand new vehicle with a little bit more than 1000 miles Not able to drive a vehicle after 15 min, very unsafe

• power train malfunction / reduced power • dealer sees the same problem / issue • I did get a "wrench" icon on my dashboard and a power train malfunction notice on my ford pass app
