2022 Ford Mustang Mach E: loss of power steering

Filed Mar 6, 2023 · Engine, Fuel system · CA

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.

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.

The HVBJB subassembly in ALL Ford Mach-e vehicles has known defects with 'under-designed' main contactors that are known to fail under normal charging and driving conditions as outlined in current open Ford recall notice for my vehicle 22s41. 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... and failure of other 12v systems due to failure to charge the 12v battery properly after contactors 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.
