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.
The battery energy control module recall software update was completed on my vehicle on september 22nd 2022 at 1203 pm at gosch ford of hemet. Upon leaving around a mile down the road I was driving around a corner. While in this corner multiple things happened at the same exact moment. My traction light momentarily flashed along with a service wrench. Vehicle skid partially off-road into the ditch. I lost control for a breif moment but was able to gain control before crashing. My speed was drastically reduced to about 1/3 of its normal power. The vehicle would still drive just much slower. Upon this happening I immediately took my vehicle back to the dealership. This recall was very vague. When I was at the dealership I initially asked the ford service salesman daniel ventura if this software changed any aspect of my vehicles performance. He then read the recall letter and said if it did it normally would say it either in the recall itself or the letter ford sends you they would normallysay it in it. It did not mention that while driving thru a corner if you loose power in the car due to a battery control module failure that you may loose traction and loose control of the car momentarily. This is a very unsafe driving condition. Furthermore when I left the dealership the car drove differently. It seemed like the horse power was about 5-10 hp less then when purchased. It felt a little weird to get used to driving down the road since it had a little bit more push then before. I mention this because I believe that as a consumer I have a right to know the software that is going into my car. If any adverse reaction that may cause me a different driving experience or put my life at risk of crashing should have been included in the safety recall or the letter ford had sent us in the recall. I am a firm believer they do not want to tell us that this vehicle is still not safe to drive as what happened to me having the battery control module failure during cornering.
To whom it may concern, Today I washed my car for the first time. My brand new Mach-E that I purchased 2 weeks ago. While going through the car wash the charging port opened up and got soaked with soap and water. This effects the vehicle charging capability and cause an electric issue to the car.
Brought Mach-E into dealership on 8/31 for recall on battery. Recall is corrected via a software update the can had not applied on its own after the last month. Car was serviced in about 2 hours and returned along with paperwork stating the recall was applied. Upon entering the car a new warning light was illuminated showing the software update was not yet complete. I assumed this just needed some more time to finish so the vehicle was driven home. Once home I used the messages on the center display to apply the update now. After about 20 min the first failure indicated the update was not applied because prerequisites were not met. A second attempt to apply the update was made and failed again. The failure clearly states it was not applied and that the update was intended to fix the specified recall. The car was immediately returned to the dealership with the error light still on at which point the service manager starts saying he’s sure they applied it but maybe the car didn’t take it. After some review the dealership they say they think the error is a conflict between the dealerships update and the over the air update systems but they believe it was actually installed even though the car says it failed. Due to other problems I’ve had at this dealership and the conflict of information at hand I don’t really have any way of knowing if this was properly applied. The dealership has asked to wait and check on it later to see if the errors continue.
Adaptive cruise control fault, pre-commission sensors not working, anti-lock break fault, restraint fault, tire pressure fault, dash turns off while driving which makes unable to see speed driving.
