2022 Ford Mustang Mach-E electrical system problems

“1) The high voltage junction box failed causing the vehicle to abruptly stall on a public road. The part will be available for inspection through contacting a local dealership. 2) The vehicle completely stalled at night in the middle of a 6 lane intersection. This posed a hazard for myself as well as for on coming and cross traffic. 3) The dealer has confirmed the failure of this component. 4) The vehicle component is being order of replacement at the dealership. The manufacture has also been informed via their corporate customer service line. 4) 5 seconds before the stall, the vehicle user interface displayed the message "please pull over safely". 10 minutes after the stall the Ford My Pass App showed three error messages: “High-Voltage Battery Warning”, “Powertrain Malfunction/Reduced Power” “Charge System Fault””

“I had put the vehicle into One Pedal Drive mode for the first time on the morning of Aug 29th. Vehicle operated as it should for first few places I drove to and stopped, but then I approached a red light, removed foot slowly from accelerator and vehicle came to a full stop as it should. Approximately 2-5 seconds later, without warning or even the collision avoidance system activating, my vehicle suddenly accelerated into the rear of the stopped truck in front of me. Fortunately no serious injuries but someone could have been killed. My foot was NOT on the accelerator at the time - it was hovering over it while waiting for the light to change to green. My vehicle was taken to Ford for evaluation, but they claim it has to be repaired before they can diagnose/confirm the issue. I am the original owner with no previous accidents or incidents.”

“I just had the High voltage battery junction box replaced after being in shop 16 days. Upon arrival to my house yesterday my car would not charge. upon further investigation once the Hvbj connector is replaced a charge of the car to put a full load on this connector is not performed. Instead ford goes the easy route and uses a test drive and other diagnostic test such as there computer to see if the connector is bad. This software does not detect even close to 100 percent of the time a faulty high voltage battery connector there diagnosis software it is flawed. The only true way to ensure proper replacement of this connector has been done is to charge the car with the charging cable that has come with the car and do thermal imaging on the connector. Because this is not being done you are putting peoples lives at risk by not knowing if the work has been done correctly without this thermal imaging test. Eventually if the high voltage battery junction box is replaced and even the slightest mis crimp of the connector is not done properly without putting a charging load on the connector and testing it with thermal imaging testing they are doing the quick and easy…”

“The high voltage battery junction box connector has failed. There have been two recalls one software and one to replace this part the high voltage battery junction box with a more robust part to handle thermal loads. As of now there are zero recalls on my car open so they are all done. The first time this component failed was around 24k miles ish it's now 56k miles ish and it has failed again even after two recalls and an investigation around the same exact time. This means one of two things has happened either somehow the recalls by Tim Moran ford where not done properly and somehow the older failed part number was installed in my car or the more likely senario is that fords supposed robust part was just a simple part number change without a robust enough design to handle the thermal load. I would like to think that Tim Moran ford who is independent from for has done there due diligence the first time it was replaced and but the correct part number which leads me to conclude the investigation by the NHSTA that resulted in a part change did not fix the issue at hand and the car is now unsafe to drive as this is the second time it has happened to me on this…”

“I am unsure, but I think it's the High Voltage Battery Junction Box. A week after buying the car used from Aaron Ford of Poway, I received a Safely Stop now warning, then the car broke down on the middle of the turning lane into my job a medical clinic putting myself, patients, other drivers, and my coworkers all on danger as it is a busy street. The hazard lights would not work, and the car would not go into neutral. The next day, all the dealership did was replace the 12v battery, then I only got 1 mile from the dealership before it broke down again in an even more busier and dangerous highway in the slow lane and crosswalk. The hazard lights would not work, and the car would not go into neutral.”

“The contact owns a 2022 Ford Mustang Mach-E. The contact stated that while driving at an undisclosed speed, the vehicle became inoperable and the vehicle stalled, and the gear shifter was inoperable. The contact exited the vehicle and was unable to re-enter the vehicle because the doors were locked and failed to unlock. The messages "Service Now" and "Battery Management" were displayed on the instrument panel. The pre-collision sensor warning light and several other unknown warning lights were illuminated. The failure had occurred on several occasions. The vehicle was towed to the residence, and the batteries were replaced. The contact researched the issue and became aware of an unknown recall; however, the VIN was not included. The vehicle was taken to a dealer, where it was determined that the battery management system needed to be reset. The vehicle was repaired, and the dealer advised the contact to drive the vehicle for 30-40 miles. However, after approximately 3 miles, the message "Stop Now" was displayed on the instrument panel, and the failure persisted. The manufacturer was not notified of the failure. The failure mileage was approximately 40,000.”
