Ford Mustang Mach E power steering loss problems

Filed Jul 9, 2025 · Electrical, Fuel system · WA

At [XXX] on Tuesday [XXX] while driving our 2023 Ford Mustang Mach E GT eastbound in the left lane on [XXX] near the [XXX] intersection the car suddenly stopped. There was a second or two of multiple warning notices then the car instrument panel went blank. The car “bricked” as is known in Electric Vehicle jargon. There was no power to anything, and the stop was sudden and steering was extremely difficult. Washington State Patrol and Washington Department of Transportation responded to provide safety assistance while eastbound traffic on [XXX] backed up for several miles. The car is now at Frontier Ford in Anacortes Washington and they have confirmed its status as completely dead. In fact it took almost an hour to get the car off the tow truck. The dealership tried several battery jumper options to the 12v battery but when they worked it seemed to only work for a few seconds before the car “bricked” again. There is probably a WSP police and WSDOT report about responding to this incident. In the seconds before the complete electrical shutdown there was a cascade of warning notices then everything went blank and the car abruptly stopped in traffic. It took over an hour to get a tow truck and then the cars “bricked” status made the towing job very difficult and eventually the car was literally dragged onto the flatbed with a winch. This incident happened during rush hour in heavy traffic and both occupants safely was put at high risk of a high speed collision from traffic approaching from the rear of the car. We have made two reports to Ford Customer Service. Case # [XXX] And case # [XXX] The suddenness and inability to maneuver and get out of traffic is a real safety problem that can lead to a severe accident.

The HVBJB subassembly in ALL Ford Mach-e vehicles has known defects with 'under-designed' main contacts that are known to fail under normal charging and driving conditions as outlined in current open Ford recall notice. Unfortunately, the internal damage to contactors is not visible externally, and warning notices on display only AFTER the damage has occurred, and can result in sudden loss of propulsion power at highway speed, loss of power steering, and power brakes... and failure of other 12v systems due to failure to charge the 12v battery properly after contacts are damaged. Less catastrophic results can include failure to start; which can 'strand' driver's and passengers in remote areas, bad weather conditions, as well as cause loss of use for weeks due to delays in replacement parts and local Dealerships needing equipment and training to effect removal/replacement of faulty unit with a new HVBJB having re-designed 'beefier' components.​ ​ My complaint is that Ford's recall notice 22s41 is a software-only attempt to prevent future damage, and does not require removal of the part(s) which are KNOWN TO FAIL to be replaced with the re-designed components which are available, and have been used to repair failures under warranty. I have no way of inspecting the original equipment to evaluate current condition; and failure can result in sudden and unexpected loss of power, steering, and braking as well as potentially 'stranding me' in unsafe conditions unable to re-start my vehicle.​ ​ I would like to see the federal safety agency strengthen the Ford recall to include both improved software AND removal/replacement of the HVBJB sub-assembly with the new 'beefier' parts.​

The HVBJB (high-voltage battery junction box) subassembly in ALL Ford Mach-e vehicles has known defects with insufficiently robust main contactors that are known to fail under normal charging and driving conditions as outlined in the federal safety agency Campaign Number 22V412000. Unfortunately, the internal damage to contactors is not visible externally, and warning notices on display only after damage has occurred, and can result in sudden loss of propulsion power at highway speed, loss of power steering, and power brakes, as well as failure of other 12V systems due to inability to charge the 12V battery properly after contactors are damaged. Less catastrophic results can include failure to start, which can strand drivers and passengers in remote areas, bad weather conditions, and also cause loss of use for weeks due to delays in replacement parts and local dealerships needing equipment and training to effect removal/replacement of faulty unit with a new, more robust HVBJB.​ ​ My complaint is that Ford's recall under campaign 22V412000 is a software-only attempt to prevent future damage, and does not require the part(s) which are KNOWN to fail to be replaced with the re-designed components which are available, and have been used to repair failures under warranty. I have no way of inspecting the original equipment to evaluate current condition; and failure can result in sudden and unexpected loss of power, steering, and braking as well as potentially stranding me in unsafe conditions unable to restart my vehicle.​ ​ I would like to see the federal safety agency strengthen the Ford recall to include both improved software AND removal/replacement of the HVBJB sub-assembly with the new, more robust parts without a known failure risk.​ Thank you very much for your time.

* On October 16th, 2022, at about 7:00 pm, I was driving my 2021 Ford Mach-E GT when we began to change lanes (we were in the left lane heading East) as the vehicle in front of us slowed down to make a left-hand turn. There was a car behind us and two vehicles in the right lane (two-lane road in each direction) that were a few car lengths behind us as we began to change into that lane. When I turned on my signal and turned the steering wheel, I pressed the gas pedal to accelerate to get around the car in front of me to keep my distance from the vehicles in the lane I was transitioning into. Unfortunately, when I pressed the gas pedal, we experienced complete vehicle failure. I had no steering, brakes, or acceleration. Within a short time (30-45 minutes), we had no power as the lights on the vehicle, and all electrically powered devices and components were entirely out. This made it very difficult to tow the car as it is all-wheel drive, and we could not put it in Neutral to pull the vehicle. As this happened, five cars were in the area, and several had to swerve and fly off the road onto the dirt shoulder. We barely missed the car in front of us, and the car behind us had to lock up its breaks not to hit us. Our car gradually slowed down and cost off the road about 50 yards or so after losing power, as it was very difficult to get the vehicle to steer; it took everything I had to turn the wheel to get it off the road. We put on the emergency blinkers, but the vehicle lights flashed erratically inside and outside the car. We had over a dozen warnings flash on our dashboard about vehicle failure. The speakers in the car were making a thumping sound on their own as the car was flashing headlights, brake lights, and flashers on their own and very sporadically. It was like a disco club in the car as all the lights were flashing on and of at a rapid rate. The other cars stoppe and were very angry at us as the screamed at us that we almost caused an accident.

Power steering went out including 10+ error / fault codes displaying on the dash on the vehicle after planned having vehicle towed but was back to normal after a restart. Exiting the parking lot at a low speed power steering failed again resulting in a low speed crash. After having it towed to dealership they reviewed software on the vehicle seeing vehicle has has fault codes and module errors for 3+ months on their Ford telemetries cloud system showing module and system errors every other day. Dealership asked if I ever got notice via vehicle or app about these errors which I never received. Ford Legal was notified and said vehicle did have a possible Bluecruise recall and nothing wrong with vehicle without having a Ford Engineer viewing the vehicle. My dealership still said cloud system showed all these errors which didn't seem be an issue to ford. My insurance said they'd make repairs but if my dealership said vehicle isn't safe they recommenced fix what is needed which Ford said 0 issues.

On May 14, 2022, I stopped twice on a 120 mile trip to recharge my Mach E at a level 3 DC charger. Upon completing each charge, the ring around the charging port turned red and I received a default message. I plugged my car into my home level 2 charger and the car completely locked down and I was unable to reenter the car. I have since learned that this is the classic sign of a HVBJB failure. The dealerships updated the car's programming but did not replace the HVBJB.
