The contact owns a 2022 Ford Mustang Mach-E. The contact stated that while having the Blue Cruise system activated at approximately 70 MPH, the vehicle suddenly drifted to the right. The contact was able to straighten out the vehicle however, the vehicle drifted to the left and then to the right again. After a while, the contact was able to regain control of the vehicle by manually operating the steering wheel instead of using the Blue Cruise system to control the vehicle. The contact stated that shortly after regaining control of the vehicle, the failure recurred in the opposite direction going from left to right, and then to the left. There were no warning lights illuminated. The contact was able to maintain control. The dealer was contacted and was able to remotely pull the codes from the vehicle for diagnostic testing.

- What component or system failed or malfunctioned, and is it available for inspection upon request? According to Ford Service, this is confirmed to be a High Voltage Battery Junction Box failure (HVBJB). The part is pending replacement currently at Central Ford, CA. While Ford issue recall (23S56) to replace all HVBJBs in Extended Range and GT model '21 and '22 vehicles built before May 24, 2022, my car was built after the date. - How was your safety or the safety of others put at risk? The failure of HVBJB directly leads to the lose of power suddenly when driving on the highway. I was cruising on california state highway CA-110 while the car pops up "stop safely now" on the instrument cluster. I lost all power for acceleration and relies purely on 12V battery to power the accesories. There was no emergency lane near the location of the incident which leads to the blockage of highway on the junction from CA-110S to I-10W. This post a significant threat to me as the driver and all other drivers on highway. More importantly, the 12V almost died before the tow truck and police could arrive to solve the incident. Fortunately, I was not hit by ongoing vehicles, but multiple vehicles have to brake agressively to prevent collision. The car was unable to be shifted to N or D since the incident. -Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle had been inspected by Service department at Central Ford and confirmed by engineers at Ford to be a HVBJB failure. - Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? 2 warnings and notifications can be seen from information cluster: "Full accessory power active", and "Stop safely now." There is no information displayed on the main infotainment screen.

The vehicle was delivered [XXX], its an EV and does probably 70% highway/30% city driving. As an EV is on "one pedal" mode exclusively to use the motor to brake the vehicle and regenerate charge to the battery so we rarely use the actual brakes. at 18k mile we notices when the brakes were applied the vehicle and steering wheel shock, we took the car in for service and the front brake rotors were re-surfaced as per Metro Ford in Miami, FL. We noticed again at 22k miles and then Metro Ford in Miami, FL replaced the front rotors as they could not be resurfaced since they were already resurfaces once and would have been out of spec. At 28k miles we notices again, we took it again to Metro Ford in Miami, FL and they said it was cause by brake pad glazing and pad needed to re-surfaced and this time also resourced the rear rotors. All this is been done under warrantee with the exception of replacement of front pads in the last repair as Metro Ford in Miami, FL considered them a "wear" item (even with clear history with brakes) the approximate cost was $427. I believe there is clearly a brake defect with my car as i dont see how an EV on one pedal driving has needed to have front rotors resurfaced 2x and replaced 1x, needed new front pads, and need rear pads resurfaced 1x in less then 2 years/28K miles.

I just had a similar experience about four hours ago during normal conditions (dry and daylight). I was approaching a red light that controlled an on/off ramp intersection where a rural road intersects a state Highway. I was on the rural road. As I started braking, the pedal almost immediately felt soft. I kept pressing (never pumped) the brake pedal steadily lexpecting to feel more normal resistance. The brake pedal traveled more than double the distance that it normally does. I started to get some braking, but I don’t think I could have locked up the brakes if I wanted to. The emergency braking didn’t engage; however, there wasn’t a car traveling in my lane between me and the intersection. There were cars exiting the freeway and turning through the intersection immediately in front of me. Fortunately, I had enough brakes to stop just before the intersection. I had my wife and son in the car. I will be having the local Ford dealership look over the car. That incident happened 5-10 minutes after leaving my house. I had used my brakes during this trip prior to the incident. The brakes worked normally for the remainder of the 20 minute trip. Whatever is going on, isn’t right and although I never was dangerously close to an accident, if conditions were slightly different it could have been very bad.

Early January 2024 recall updated to remedy available with note to schedule service with your advisor. 3. Called Mullinax Ford in Apopka Florida second week in January and clearly stated I was calling to schedule an appointment for HVBJB recall, noted above. Appointment was made for next available which was February 12, 2024. 4. February 12, 2012 I take vehicle to Mullinax Ford for 7:30am appointment. Advisor writes up HVBJB issues along with tire rotation and another software update for stuck charging plug. 5. Throughout the 6 hours of waiting at the dealer the service advisor neither updates me or informs me that the HVBJB recall is not taking place. They apparently performed another recall for a parking break release cable that was neither listed on the ford site or NHTSA as a recall applicable to my vehicle. 6. At the end of the 6hours they hand back my vehicle without the HVBJB recall performed and could not tell me when it could be performed or if parts were available or if they had even checked for the parts. They simply said they would get back in touch. I left to mull things over and clear my head. 7. Called back Mullinax Ford from the car and talked to someone named Michael after asking for the service manager. Explained I specially made the appointment a month ago for the HVBJB recall and that didn't happen and I wanted to know when they could have the part on hand and when I could schedule the recall. He said he would research it and call me back. 8. As of [XXX], three days later, I have not received an update. 9. The recall status now shows remedy unavailable again which means the part is obviously on back order. 10. This HVBJB problem surfaced in early 2022. The first recall which consisted of a software update in was issued in June 2022. There is no excuse for not having ample parts to remedy this in 2024. No long distance/fast charge driving.

I have had 14 incidents over two years where this vehicle suddenly, rapidly accelerates from slow speed, usually less than 15 mph, and six of those incidents had a near collision. Most of the incidents happen in a parking lot or drive-thru and require immediate fast braking to avoid collision. This sudden, unexpected acceleration has been widely discussed on the Mach-E Forum and there is general agreement the cause is inadvertent engaging cruise control by accidentally hitting an overly sensitive button on the steering wheel when the hands are in the 9 to 3 position. I have reviewed all related threads on the forum and counted 36 different owners who have experienced this same problem, most reporting near collisions and serious concerns for safety. Some posters have described possible remedies.

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.

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 Preliminary Evaluation is being upgraded to an Engineering Analysis (EA25001) 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.
RQ23004 · High Voltage Battery Contactor Failure

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.
