1) The high voltage junction box failed causing the vehicle to abruptly stall on a public road. The part will be available for inspection through contacting a local dealership. 2) The vehicle completely stalled at night in the middle of a 6 lane intersection. This posed a hazard for myself as well as for on coming and cross traffic. 3) The dealer has confirmed the failure of this component. 4) The vehicle component is being order of replacement at the dealership. The manufacture has also been informed via their corporate customer service line. 4) 5 seconds before the stall, the vehicle user interface displayed the message "please pull over safely". 10 minutes after the stall the Ford My Pass App showed three error messages: “High-Voltage Battery Warning”, “Powertrain Malfunction/Reduced Power” “Charge System Fault”

I had put the vehicle into One Pedal Drive mode for the first time on the morning of Aug 29th. Vehicle operated as it should for first few places I drove to and stopped, but then I approached a red light, removed foot slowly from accelerator and vehicle came to a full stop as it should. Approximately 2-5 seconds later, without warning or even the collision avoidance system activating, my vehicle suddenly accelerated into the rear of the stopped truck in front of me. Fortunately no serious injuries but someone could have been killed. My foot was NOT on the accelerator at the time - it was hovering over it while waiting for the light to change to green. My vehicle was taken to Ford for evaluation, but they claim it has to be repaired before they can diagnose/confirm the issue. I am the original owner with no previous accidents or incidents.

I was pulling into a parking lot at low speed when the car suddenly began accelerating rapidly on its own. Fortunately, when I hit the brakes it stopped without incident. However, if someone had been right in front of me at the time - a pedestrian or car - it could have resulted in a crash. I am certain that I didn't hit the accelerator, nor was it pushed by floor mats or anything like that. It is conceivable that when I was turning, my left palm activated the cruise control in some manner, but that scenario wouldn't explain the acceleration part. And frankly, I don't think that is what happened. I love the vehicle and am not trying to get anything out of it. I am a capable driver with good reflexes and experience. I was able to stop it, but if this were to happen to a new driver or senior driver it could result in a crash. I looked on reddit and many others report exact same issues.

I was driving my car when all of a sudden it lost all acceleration and power, I was lucky that I wasn't on the highway anymore and was able to pull over safely on a side street while car was rolling still. Dealer said 12V battery fused, and I have been reading forums where this is a common issue.. In a normal ICE car when 12V battery dies while driving, car can still drive, in this case, it just stops and pops up a dozen errors about everything being broken.

Ford knowingly sold unsafe vehicles. the federal safety agency caught them and forced a recall on the High Voltage Junction Box (they are still failing, so you may want to look into this). But what they have hidden from you and all of it's customers that they suckered in buying their defective product, is that the front motors, have undersized wiring, which could cause a fire . They have attempted to hide this from the public, by limiting the power of the car to 5 seconds of full power and then dramatically decreases the power after that. The sold the cars to consumers without revealing that fact, so folks bought the performance "GT" versions and yet they are neutered. It's only a matter of time, where those tiny wires in the front motors give up and start causing fires. It's time for the government to stand up for he consumer here. I've brought it to [XXX] 's attention, but they are hoping we all go away and allow them to get away with selling a defective potentially dangerous vehicle INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

- What component or system failed or malfunctioned, and is it available for inspection upon request? According to Ford Service, this is confirmed to be a High Voltage Battery Junction Box failure (HVBJB). The part is pending replacement currently at Central Ford, CA. While Ford issue recall (23S56) to replace all HVBJBs in Extended Range and GT model '21 and '22 vehicles built before May 24, 2022, my car was built after the date. - How was your safety or the safety of others put at risk? The failure of HVBJB directly leads to the lose of power suddenly when driving on the highway. I was cruising on california state highway CA-110 while the car pops up "stop safely now" on the instrument cluster. I lost all power for acceleration and relies purely on 12V battery to power the accesories. There was no emergency lane near the location of the incident which leads to the blockage of highway on the junction from CA-110S to I-10W. This post a significant threat to me as the driver and all other drivers on highway. More importantly, the 12V almost died before the tow truck and police could arrive to solve the incident. Fortunately, I was not hit by ongoing vehicles, but multiple vehicles have to brake agressively to prevent collision. The car was unable to be shifted to N or D since the incident. -Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle had been inspected by Service department at Central Ford and confirmed by engineers at Ford to be a HVBJB failure. - Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? 2 warnings and notifications can be seen from information cluster: "Full accessory power active", and "Stop safely now." There is no information displayed on the main infotainment screen.

Car suddenly lost all power and flashed multiple warnings. Steering also became disabled. This was moving at a low speed through a school zone so it did not cause an accident. After several restart attempts the car moved again but quickly same issue occurred. Car was towed to Ford. Still waiting for diagnostic.
