I parked my MachE at home on Sunday evening and I had "lock the car when i walk away" setting turned ON. I also had alarm system turned ON. Car keys were more than 20-25ft away in my home. So, technically no one should be able to break into my car without sounding an alarm. Yet, theft happened on Monday morning without any physical damage to the car and no alarm was sounded. Ford said take the car to dealer and dealer said they don't know how to get the car logs to determine what\how happened and they want to charge me a fee just to take a look at it. Car also had my garage door key programmed, so thief could have simply opened the garage and could come it right away while kids and we were sleeping - it's big security risk. It very much sounds like some fault in the car as one of the scenarios - 1) it didn't lock on Sunday evening even though I had walk away lock setting turned on, or 2) it's so easy to fake or replicate the signals from the key which was stored at home or 3) alarm system is at fault and it didn't trigger for some reason.

While driving on Route 1 and attempting to pass another motorist, a flashing red "STOP SAFELY NOW" lit on my dashboard, along with multiple warnings of a "powertrain failure". Thankfully I was near my house and was able to get home. But the FordPass App is saying that I had a high-voltage power malfunction and will need to tow the car to my local dealership. Now I am being told that the high-voltage junction box has failed and needs to be replaced (consistent with Ford Recall notice 23S56). Unfortunately, Ford hasn't produced a replacement part, and after speaking with multiple dealerships, I have been told that an updated replacement part may not be available until Q1 2024 (Or between 6-18 weeks from now). Those of us who purchased these vehicles now have $65K+ paperweights. Ford should buy back these cars, fix them, then resell them through local dealerships. Please help remedy this situation.

On this vehicle, it looks like I may have some arcing on the pins on my car where the charging port hooks up. This car has burnt up two charging cables. What I would like Nhsta to ask Ford is nowhere in this customer satisfaction program does it say they will replace the burnt pins on anyone's cars if they have them. Also, I do not see any recall for this issue as every single mach e that has any chance of having burning pins in their charging port should be inspected. I have received this letter on my 2022 mach e and 2023 one and I will make a complaint for both. There should not only be a recall opened up on this to properly inspect every single charging port for any kind of arching as any kind of arching may have caused damage not only to the pins but the entire electrical system or any one of the components that go from the pins to the batteries. Furthermore of a recall I also ask that an investigation be opened to Ford itself since they cannot tell customers who pay a ton of money for there vehicles why they did not open a recall or notify Nhsta in the first place. This is even worse in my opinion then the last two recalls when they tried to give us software knowingly having an updated part that was more robust for the battery control module to have to be investigated in order to replace it. This should not be tolerated. My safety, my family's safety, and everyone else's safety who owns one of these vehicles is the main importance to me. Like I said looks like I may have some arching on my pins on my car charging port but who would know Ford is not even going to replace them or inspect them there is no recall for this that I have seen. Shady as usual shame on you Ford I hope NHSTA drops the hammer on you this time and the last time.

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 NHTSA 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 NHTSA 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 NHTSA 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.

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 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.
