On November 18, 2022 my vehicle's High Voltage Battery Junction Box (HVBJB) failed. Ford replaced this part with an "upgraded" version of this part and I received my car back on November 28th. Shortly thereafter, the federal safety agency issued a recall, the solution for which was a software update that my car received. On October 10, 2023 my vehicle's HVBJB failed once again (the newer upgraded part). Coincidentally, while my car was in the shop, the federal safety agency issued a second recall for this issue, indicating that Ford would be recalling the physical HVBJB. Shortly after this recall, my recall was marked as complete because I received the upgraded version of the part once again. Ford's upgraded part that is a solution to this issue has been issued in many Mach-e cars and is the standard for late '22 models and '23 models; however, in addition to my own HVBJB failing, I am hearing many instances of this newer part failing. Being that this recall stemmed from vehicles potentially losing propulsion as a result of this failure, the risk still exists (although potentially at a lower rate). I do, however, believe that Ford knows that this failure rate is still high and that their upgraded part does not provide a sufficient solution to the problem but has not been transparent with the federal safety agency due to the costs associated with redesigning a third version of this part. I do not feel safe driving my family in this car because I know that it's just a matter of time before this part fails once again.
2022 Ford Mustang Mach E fuel system complaints

The high voltage battery junction box failed on my car at 9500 miles, and now again at 19200 miles. Failure prevents the car from running properly, or at all. The dealership is reporting that Ford has not developed an updated replacement part, and is only replacing with the same part that the vehicle left the factory with.
While driving the vehicle in the highway the service/malfunction indicator light (MIL, wrench symbol) turned on and the vehicle dramatically lost propulsion power limiting my acceleration/speed. I opened the Ford Pass App on my phone and the following messages were shown regarding the issue: "High-Voltage Battery Warning and Powertrain Malfunction/Reduce Power". The message in the app also indicated to contact the dealer immediately. I would estimate that max acceleration was instantly reduced over 30%, causing a great concern while cruising at highway speeds. Previous to the date of this incident, the warning/check engine light never turned on. I made the next exit to use secondary roads as a precautionary measure since the max acceleration was limited. I am very active in various Mach-E forums, and this is a well-known issue for Ford. These messages are the ones related to a potential design problem with the High Voltage Battery Junction Box (HVBJB) included in my vehicle (Mach-Es built on or before May 28, 2023). My production date was January 2022. This vehicle got the safety recall #22S41 (software update) at the dealer last year. The software basically allowed the driver to get these warning messages if issues with the HVBJB contactors were detected. It is noteworthy to mention that I did not get the “Stop Safely Now” message, which would have made the vehicle undrivable. Next morning the wrench symbol disappeared from my instrument cluster. Ford issued a technical service bulletin #23-2257 to address a fix, which will involve the replacement of the potentially defective HVBJB for a redesigned one. The dealer indicated the remedy Ford provided was the software update, however multiple owners have reported the replacement of the potential defective part by Ford can only be done if the vehicle is totally inoperable showing the "Stop Safely Now" message. A sudden loss of propulsion while cruising at highway speeds is a safety concern for driver and others.
Powertrain malfunction warning while driving to work on 55MPH road. This has occurred twice since buying the car new. November 14, 2022 with 9k miles was when the first warning/malfunction occurred. HVBJB was replaced. This last/second powertrain malfunction and High-Voltage battery warning occurred on May 26, 2023 with 15k miles. HVBJB replaced again. This warning resulted in reduction of power, but not full loss of power. Unfortunately, the last time this occurred was when I was attempting to pass on a two lane road. The power reduction when this warning occurred prevented me from safely passing and getting back in to my lane. Image of warnings on my Ford app are attached for details and dates. Northfield Ford (Northfield, MN) replaced the HVBJB on both occurrences. I have never used a DC Fast Charger. Most used charger is 110v.
I bought a 2022 mustang Mach e. Which was supposedly fixed at the factory in regards to the HVBJB issue. However, in mid 2023, my vehicle suffered a limp mode/warning about reduced power while on the interstate, was limited to about 60mph with very poor acceleration. Was diagnosed by ford tech as a failure of the recalled part and required HVBJB and BECM replacement, similar to 22V‑412 recall. I think this should be added to RQ23004 investigation, as these vehicles had both the new hardware and software and were supposed to be “fixed”.
After charging for the first time at a DC fast charge station to 80%, I resumed my trip and drove about 3 miles to merge onto the expressway, my screen panel said "safely stop now", with a turtle logo and battery icon coming on. my car then came to a complete stop within a few seconds in the middle of the on-ramp leaving me stranded. I repeatedly tried to turn the car on and off to see if i could get it to accelerate again but to no avail. I was stuck in the middle of the merge lane where my car would not move. After trying several attempts to rebooting, locking, turning off the car completely for 10-30 minutes, nothing worked. Although the accessory power said it was active there was no AC. After a couple of hours of waiting for a tow truck that would actually work with an EV, I locked the car again and tried to start. There were no warning lights so I tried to go to get off the expressway. After 3 miles at 70mph, the same warning lights came on and the car started to decelerate and then stopped. Luckily I was able to get over to the side of the interstate. After still waiting on tow truck for another 2 hours, lights inside the car started blinking, a loud banging sound started coming from the car and then nothing would work. Screens were black, doors were locked, windows wouldn’t roll up. No accessory power at all. It was 95° in Florida sun and I was completely stuck in the middle of nowhere at the mercy of any tow truck that would come help. It took 6 hours to get someone to come. He jumped the 12V battery and the car turned on and we loaded it onto the flatbed and took it to the dealership. Waiting now to see what is happening.
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.
