   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.…

   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…

   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. NHTSA 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…

   On November 18, 2022 my vehicle's High Voltage Battery Junction Box (HVBJB) failed. Ford replaced this part with an "upgraded" version of this part and I received my car back on November 28th. Shortly thereafter, the NHTSA issued a recall, the solution for which was a software update that my car received. On October 10, 2023 my vehicle's HVBJB failed once again (the newer upgraded part). Coincidentally, while my car was in the shop, the NHTSA issued a second recall for this…

    The high voltage battery junction box failed on my car at 9500 miles, and now again at 19200 miles. Failure prevents the car from running properly, or at all. The dealership is reporting that Ford has not developed an updated replacement part, and is only replacing with the same part that the vehicle left the factory with.
