My 2021 Mustang Mach-E GT Performance is exhibiting a Powertrain Failure and Stop Safely Now message in the instrument panel cluster (IPC). It is due to a high voltage battery junction box (HVBJB) failure. Ford needs to replace the HVBJB with an updated part and reprogram the BECM, at least. The dealer has no information on the replacement part, and has not associated TSB 21-2178 with the vehicle.

My vehicle has 13,000 miles on it and I have been driving it without any problems until August 12, 2022 when I turned the vehicle on and there was "service now" and a "Battery service" message. I was aware of this problem because it was posted online and Ford has sent me mail about this problem but I thought it could be fixed by an over the air update, which I performed already. So I contacted the nearest dealer to book an appointment to remedy this issue but the next available appointment was on August 31st so it was 2 weeks from then. I decided to give it a shot and drive it and I was able to drive approximately 40 miles before the car shut down as I was turning right on a stoplight on my way to work. The propulsion did not work along with a series of multiple error messages on all systems. I was able to bring the car to the side of the road, in front of a tire service company's parking lot. I tried to start and restart it but to no avail. I called the nearest Ford dealership and they accepted my vehicle so I called a towing service to tow my vehicle to them. I decided to step out of the vehicle and inform the establishment about the situation and that I called a towing service already. When I tried to get in, the doors did not work anymore so I was not able to get in. The towing service arrived and told me to put my car to neutral gear so she can pull it up the bed of the tow truck. I said I could not get in and she stated that she might damage the vehicle if she tried to pull it while it is on park. I had no choice but to agree because I cannot get in the vehicle to change the gear. She had me sign a waiver that states that I accept any possible damages that the vehicle might incur during the towing process. She was able to get the vehicle on the tow truck and deliver it to the dealership I mentioned and now they are trying to repair it. I was aware of this issue beforehand but Ford stated that this issue can be resolved with a simple software update.

My vehicle had the NHTSA Recall Number 22V412 performed 2 weeks ago via an OTA update. Today while driving the vehicle I had critical failure while the vehicle was in motion rendering the vehicle unsafe. It was determined that the part which failed was the part addressed in the recall campaign. The recall should not be considered satisfactory remediation of the issue as it did nothing to prevent this safety concern with my vehicle. Software cannot fix an improperly designed piece of hardware.
The vehicle would not start and display an error message "pull over safely now" which the car was not able to put in any gear. This incident happened 2 times already. The first incident was when i drove the vehicle from Oregon to California. As i was about to leave the next morning from the hotel, the vehicle would not turn un a…

The vehicle would not start and display an error message "pull over safely now" which the car was not able to put in any gear. This incident happened 2 times already. The first incident was when i drove the vehicle from Oregon to California. As i was about to leave the next morning from the hotel, the vehicle would not turn un and display the message "pull over safely now". We had to call a tow truck to pick up the vehicle and drop it off at a Dealership in California for about 30 days. We pick up the vehicle and drove back to Oregon and the same issue happen again in less than a week with the same error message "pull over safely now".
Failure of HVBJB after associated recall compliance. One day after recall compliance, “stop safely now” message displayed, vehicle would not power up. Towed to dealership. HVBJB failure verified via FDRS. Dealership replaced HVBJB.
On May 14, 2022, I stopped twice on a 120 mile trip to recharge my Mach E at a level 3 DC charger. Upon completing each charge, the ring around the charging port turned red and I received a default message. I plugged my car into my home level 2 charger and the car completely locked down and I was unable to reenter the car. I …

On May 14, 2022, I stopped twice on a 120 mile trip to recharge my Mach E at a level 3 DC charger. Upon completing each charge, the ring around the charging port turned red and I received a default message. I plugged my car into my home level 2 charger and the car completely locked down and I was unable to reenter the car. I have since learned that this is the classic sign of a HVBJB failure. The dealerships updated the car's programming but did not replace the HVBJB. 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.

The contact owns a 2021 Ford Mustang Mach-E. The contact stated that the vehicle failed to start. The contact stated that “Stop Safely Now" and "Accessory Power Active" messages were displayed. The contact exited the vehicle and upon attempting to unlock the doors, the doors failed to unlock. The contact was unable to unlock the vehicle for several hours and remained stranded on the side of the road while awaiting assistance from Roadside Assistance. The vehicle was towed to the dealer where the battery was replaced and an unknown software update was completed; however, the failure recurred. The contact later received notification of NHTSA Campaign Number: 22V412000 (Electrical System) however, the part to do the recall repair was not yet available. Airport Marina Ford (5880 W Centinela Ave, Los Angeles, CA 90045) was also contacted. The vehicle was not repaired. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the failure. The failure mileage was approximately 6,000. Parts distribution disconnect.

The HVBJB subassembly in ALL Ford Mach-e vehicles has known defects with 'under-designed' main contactors that known to fail under normal charging and driving conditions as outlined in current open Ford recall notice for my vehicle 22s41. Any internal damage to contactors is not externally visibley, 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, 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 NEED 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 band aid and does not require removal of the parts KNOWN TO FAIL. These parts should 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 suffered a failure related to this post-recall and had a sudden and permanent loss of power while driving at Texas highway speeds (70mph) in congested morning traffic. Fortunately I was able to make my way off the highway but other conditions could have ended up worse. Software "fixes" are not the solution and the actual problem of the defective parts need to be replaced in the affected models to avoid possible injuries and fatalities from these vehicles.

4EA25001 · Collisions Involving Ford Bluecruise
Opened Jan 17, 2025 · No close date supplied
Status: open (inferred from source dates) · Electrical System:adas
On April 25, 2024, NHTSA’s Office of Defects Investigation (ODI) opened a Preliminary Evaluation (PE24012) to assess BlueCruise, a partial driving automation system available on certain vehicles manufactured by Ford Motor Company (Ford). NHTSA opened the investigation after the agency received notice of two fatal collisions involving BlueCruise-equipped Ford Mustang Mach-E vehicles. Based on the incidents, NHTSA scoped the investigation to 2021-2024 Mustang Mach-E vehicles equipped with BlueCruise. In June 2024, ODI sent an Information Request (IR) letter to Ford requiring that it provide certain information pertaining to crashes, non-crash reports, and technical specifications that relate to BlueCruise, as well as other Ford partial driving automation systems that offer lane and speed maintenance. In its response to ODI’s IR, Ford stated that there are 2,539,962 Ford and Lincoln vehicles (including subject and peer vehicles) equipped with a partial driving automation system within the scope of the request. The majority of these vehicles are equipped with a system that Ford calls Lane Centering Assist (LCA), which is a hands-on partial driving automation system that combines longitudinal control authority governed by Adaptive Cruise Control (ACC) and lateral control authority governed by a steerable path. LCA is offered on a wide range of Ford and Lincoln models beginning in model year 2019. Vehicles that are equipped with BlueCruise, the focus of this investigation, have LCA capability and additionally offer hands-free partial driving automation when certain conditions are met. Hands-free BlueCruise operation is only offered on certain roadways and system availability is geofenced using vehicle GPS. BlueCruise-equipped vehicles employ a camera-based driver monitoring system to determine driver attentiveness to the roadway. BlueCruise was introduced in model year 2021 and is currently available in a select range of Ford and Lincoln vehicles. For BlueCruise- and LCA-equipped vehicles, both ACC and Pre-Collision Assist (PCA) features use a combination of camera and radar sensing technologies to detect and classify objects. ACC is specifically designed to detect vehicles (including cars, trucks, and motorcycles) and bicycles in front of the subject vehicle which are either stationary or moving in the same direction as the subject vehicle. Through this investigation, limitations in the detection of stationary vehicles in certain conditions have been identified. Specifically, due to the potential for false detection of stationary objects at long distances, Ford designed ACC to inhibit any response to reported stationary objects when the subject vehicle’s approach speed is at or above 62 mph. Additionally, system performance may be limited when there is poor visibility due to insufficient illumination. In addition to reviewing Ford’s response to ODI’s IR, the agency conducted a review of crash and non-crash reports identified collectively through Ford’s IR response, incident reporting through Standing General Order 2021-01 (SGO), and NHTSA vehicle owner questionnaires. In total, 32 crashes and 2,004 non-crash reports on subject and peer Ford vehicles were identified across manufacturer and ODI data sources. A detailed analysis of each crash was conducted including the review of any available police reports, photographs, data recovered from in-vehicle event data recorders, connected vehicle data, and/or other information. In both fatal collisions referenced in the PE24012 opening resume, the subject Ford Mustang Mach-E vehicle was traveling over 70 mph on a controlled-access highway during nighttime lighting conditions with hands-free BlueCruise engaged when it collided with a stationary vehicle. Analysis of data imaged from the vehicles’ event data recorders demonstrates that in each incident, the driver did not apply the brakes or take evasive steering action, and no deceleration was initiated by either the BlueCruise system or PCA prior to impact. Through the agency’s crash analysis, four additional frontal collisions were identified where the subject Ford impacted a stopped or slow-moving lead vehicle or another stationary object located in the travel lane. Two of these four incidents involved BlueCruise-equipped Ford Mustang Mach-E vehicles (included in the failure report summary along with the fatal collisions discussed above), while the other two involved other Ford models equipped with the LCA system. Additionally, a trend was identified through analysis of the non-crash reports relating to allegations that ACC (the longitudinal component of both BlueCruise and LCA) failed to detect and/or respond to a stopped or slow-moving lead vehicle. In these reports, consumers often describe that the absence of deceleration initiated by ACC was unexpected and required harsh manual braking or intervention from the PCA to avoid a frontal collision with the lead vehicle. Based on NHTSA’s analysis, system limitations relating to the detection of stationary vehicles while traveling at highway speeds and in nighttime lighting conditions appear to be factors in collisions under investigation and several apparently similar near-miss, non-crash reports. This Engineering Analysis (EA) is being opened to further investigate these system limitations and to evaluate drivers’ ability to respond to scenarios that exceed system limitations. During the EA, the agency expects to, among other things, perform vehicle evaluations, review additional technical information, and perform additional analysis of related crashes and non-crash reports. The crashes included in the failure report summary can be found at NHTSA.gov under the following SGO report identification numbers: 502-7268, 502-7426, 502-6852, 502-8738.

On April 25, 2024, NHTSA’s Office of Defects Investigation (ODI) opened a Preliminary Evaluation (PE24012) to assess BlueCruise, a partial driving automation system available on certain vehicles manufactured by Ford Motor Company (Ford). NHTSA opened the investigation after the agency received notice of two fatal collisions involving BlueCruise-equipped Ford Mustang Mach-E vehicles. Based on the incidents, NHTSA scoped the investigation to 2021-2024 Mustang Mach-E vehicles equipped with BlueCruise. In June 2024, ODI sent an Information Request (IR) letter to Ford requiring that it provide certain information pertaining to crashes, non-crash reports, and technical specifications that relate to BlueCruise, as well as other Ford partial driving automation systems that offer lane and speed maintenance.

On August 17, 2023, the Office of Defects Investigations (ODI) opened RQ23-004 to investigate instances of loss of motor power due to overheating high voltage battery contactors in model year (MY) 2021-2022 Ford Mustang Mach-E vehicles (subject vehicles). This Recall Query (RQ) was opened after receiving 12 consumer complaints alleging a high voltage battery main contactor failure in subject vehicles that were included in Recall 22V-412 and remedied prior to the reported incidents. The remedy in 22V-412 was a Secondary On-Board Diagnostic Control Module (SOBDMC) software update to monitor contactor temperature and reduce battery power to prevent damage to the contactor, and a Battery Energy Control Module (BECM) software update to monitor contactor resistance to identify an overheated contactor and reduce vehicle power to prevent further damage. On October 13, 2023, Ford filed Recall 23V-687 of 34,762 2021-2022 Ford Mustang Mach-E vehicles produced from May 27, 2020 to May 24, 2022 with recalled Bussed Electrical Center parts NK48-10C666-AA, NK48-10C666-BA, or LK98-10C666-AB. Affected vehicles are equipped with the extended range battery. Ford stated that preexisting damage to the contactors caused by heat and accumulated wear may reduce the effectiveness of the software update remedy in 22V-412. The remedy of 23V-687 is to complete a replacement of the Bussed Electrical Center, or High Voltage Battery Junction Box. In addition, Ford stated that subject vehicles equipped with standard range batteries, in comparison to vehicles equipped with extended range batteries, are less at risk of experiencing this failure due to their smaller battery capacity and lower output electric drive motors. In view of the recall action taken by Ford, ODI is closing this investigation. ODI will continue to monitor reports of this failure in both extended range and standard range models. The Agency reserves the right to take additional action if warranted by future circumstances.
