While returning from vacation, driving home on the highway, our car suddenly stopped working. We had been traveling at approximately 65 mph on SR 1 in Delaware when I accelerated to pass another vehicle and the car suddenly jolted forward and the engine seized. I received a warning to pull to a safe location as soon as possible. Thankfully, we were able to pull the car over to the shoulder of the highway without incident. The cars electrical system gradually shut down, limiting our ability to place the vehicle in neutral for towing. Approximately 250 miles from home and forced to wait more than 2 hours in the 90 degree weather with no AC, we were forced to bring the car to the nearest ford dealership in new castle Delaware. Since the battery and power completely failed, the dealership had to jump the 12 volt battery several times to get the car back in neutral to remove the vehicle from the tow truck. We needed to find our own car rental as neither the dealership nor ford customer service would assist with getting us back home to NY.
2021 Ford Mustang Mach E transmission complaints
Page 3 of 3: complaints 41 to 53 of 53, newest first, as owners wrote them.
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
Power loss a week ago. Had to have Mach E towed to dealership. Ford is aware of Mach E power loss.
While legally passing a car on a 2-lane highway, at over 50+ mph, the car lost motive power and began to shut down leaving me with no power facing on coming traffic. I had no choice but to force other cars to slow down behind me, causing another hazard, in order to get to the side of the road. I could have been killed in an oncoming car collision.
The contact owns a 2021 Ford Mach-E. The contact stated while reversing from his driveway, he shifted into drive and depressed the accelerator pedal. However, the vehicle accelerated at high speed independently. There was no warning light illuminated. The contact continued to drive. The contact stated that the failure reoccurred the following day. The contact stated while his wife was exiting the carwash and making a left turn with a passenger in the front passenger seat, she shifted from neutral into drive and depressed the accelerator pedal. The vehicle accelerated at high speed independently and crashed into the block wall. The air bags deployed. The contact's wife sought medical assistance and was informed that she had sustained a fractured rib on the left side of her body, pain on the shoulders, and pain in the rib cage. The passenger occupying the front passenger's seat sustained pain all over her body and a bruised rib and she sought medical assistance. A police report was filed. The vehicle was towed to a tow lot where it was totaled. The dealer was not notified of the failure. The manufacturer was notified of the failure. The contact became aware of the federal safety agency Campaign Number: 22V333000 (Vehicle Speed Control, Power Train), which he associated with the failure. The failure mileage was approximately 18,000.
Driving our BEV Mach E at a normal speed, we got an error code, "Pull to the side of the road safely / stop safely" on our instrument display. The car turned itself off, and we had to slowly coast to the side of the road, which caused a lot of potential harm with other drivers not expecting our sudden course change - We activated our hazards, though. After cycling the car on/off, we were able to finish our drive home (about 8 more miles) with no further error codes. But this completely disabled the car and was extremely dangerous. If this had happened on the freeway or at night, and/or the vehicle would not have been able to be restarted, this would have been EXTREMELY DANGEROUS and is UNACCEPTABLE. Ford must be responsible for this, and must take action. Ford must fix the high voltage junction box, before someone is killed by this poor design. Thank you for taking the time to look at this note. This was VERY scary, and VERY dangerous.
Travelling from WI to NC using Electrify America DC fast chargers along the way. While in NC, got Stop Safely Now alert on screen and had to immediately pull over and stop where there was no shoulder. Could not move vehicle in any way after this. Could not put it in N, could not put it in Emergency Tow Mode. Had to wait 8 hours for tow with proper equipment. Issue was caused by failure of HVBJB - High Voltage Battery Junction Box which needed to be replaced.
During a normal maintenance service appointment car had a Stop Safely Now error message appear. Diagnosis was a bad High Voltage Battery Junction Box and BECM. With were replaced and car has been fine since then
Second time this has happened. A message will pop up saying “please stop safely now” once you stop you can not get it out of park. If your driving you are stuck wherever you are. I was stranded the first time with no heat in 20 degree weather. They fixed it after having it for a month then it just happened again today in 80 degree weather with my kids in the car. This has happened to multiple other people as well.
Was driving 55+ mph on freeway, was told by the car to 'stop safely' Had no accelleration, no power steering, came to a stop at a stop sign, could not shift to neutral to move it.
Car was parked in my home garage and would not start, displaying "Stop safely now." Vehicle appears to have code P0AA1 Hybrid battery positive contactor - circuit stuck closed. Many other Mach-E vechicles are exhibiting this defective part in the high voltage battery system, which appears to be the Battery Electrical Control Module (BECM). Ford appears to be aware of this issue, and, unconfirmed, has stopped production of the Mach-E to canibalize parts to fix vehicles that fail. However, some are less lucky than me and had their car stop dead while driving on the highway, and Ford should not be waiting for vehicles to stop and strand people before fixing this serious defect.

Second time in less than two weeks: Vehicle started making grinding noise, and a warning came up on the screen SHIFT SYSTEM FAULT, service soon. But the car came to a halt a hundred feet later, then would not get in or out of any gear, parking brake could not be released, vehicle could not get into Neutral so not able to push or roll it. I was barely able to get out of an intersection today (Nov 11), and rolled into a parking area on Oct 30 with the same fault. After about a half hour, vehicle could be moved but would show the fault shortly afterwards, locked up. Vehicle was towed on Oct 31 to dealership, they checked fault codes, performed some software updates and test drove 4 miles. They returned the car. Today, same thing happened. Car was at an intersection. Called AAA and still waiting for them to schedule a tow truck (required wheel lift and dolly). Fortunately I was on back roads today but this is a serious problem which would have been much worse on a highway. Car is not drivable. Again, this is the second time in two weeks!
As I was driving down the road (in motion / city street) at 30 miles per hour in my brand new (4 week old / 2200 miles) all electric ford mach e, the display flashed multiple warning lights that came too quickly to decipher, and then the car went dead. I was able to pull off the road and come to a stop. At this point the car was completely dead. Even the hazard lights wouldn't work which made the situation dangerous since the cars behind me could not tell that there was a problem.
