There are 2 owner-reported suspension complaints for the 2021 Ford Mustang Mach-Ein NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The contact owns a 2021 Ford Mustang Mach-E. The contact stated that on several occasions while driving at various speeds, the vehicle was extremely bouncy. Additionally, the contact stated that while making left or right turns, the vehicle lost traction and skipped. The contact stated that steering control was lost momentarily when the vehicle skipped. The vehicle was taken to a tire shop where the tires were replaced with wider sized tires, but the failure persisted. The manufacturer was not notified of the failure. The failure mileage was approximately 38,000.
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 NHTSA strengthen the Ford recall to include both improved software AND removal/replacement of the HVBJB sub-assembly with the new 'beefier' parts.
