The contact owns a 2021 Ford Mach-E. The contact stated while reversing from his driveway, he shifted into drive and depressed the accelerator pedal. However, the vehicle accelerated at high speed independently. There was no warning light illuminated. The contact continued to drive. The contact stated that the failure reoccurred the following day. The contact stated while his wife was exiting the carwash and making a left turn with a passenger in the front passenger seat, she shifted from neutral into drive and depressed the accelerator pedal. The vehicle accelerated at high speed independently and crashed into the block wall. The air bags deployed. The contact's wife sought medical assistance and was informed that she had sustained a fractured rib on the left side of her body, pain on the shoulders, and pain in the rib cage. The passenger occupying the front passenger's seat sustained pain all over her body and a bruised rib and she sought medical assistance. A police report was filed. The vehicle was towed to a tow lot where it was totaled. The dealer was not notified of the failure. The manufacturer was notified of the failure. The contact became aware of NHTSA Campaign Number: 22V333000 (Vehicle Speed Control, Power Train), which he associated with the failure. The failure mileage was approximately 18,000.

Driving our BEV Mach E at a normal speed, we got an error code, "Pull to the side of the road safely / stop safely" on our instrument display. The car turned itself off, and we had to slowly coast to the side of the road, which caused a lot of potential harm with other drivers not expecting our sudden course change - We activated our hazards, though. After cycling the car on/off, we were able to finish our drive home (about 8 more miles) with no further error codes. But this completely disabled the car and was extremely dangerous. If this had happened on the freeway or at night, and/or the vehicle would not have been able to be restarted, this would have been EXTREMELY DANGEROUS and is UNACCEPTABLE. Ford must be responsible for this, and must take action. Ford must fix the high voltage junction box, before someone is killed by this poor design. Thank you for taking the time to look at this note. This was VERY scary, and VERY dangerous.

Car was parked in my home garage and would not start, displaying "Stop safely now." Vehicle appears to have code P0AA1 Hybrid battery positive contactor - circuit stuck closed. Many other Mach-E vechicles are exhibiting this defective part in the high voltage battery system, which appears to be the Battery Electrical Control Module (BECM). Ford appears to be aware of this issue, and, unconfirmed, has stopped production of the Mach-E to canibalize parts to fix vehicles that fail. However, some are less lucky than me and had their car stop dead while driving on the highway, and Ford should not be waiting for vehicles to stop and strand people before fixing this serious defect.

Second time in less than two weeks: Vehicle started making grinding noise, and a warning came up on the screen SHIFT SYSTEM FAULT, service soon. But the car came to a halt a hundred feet later, then would not get in or out of any gear, parking brake could not be released, vehicle could not get into Neutral so not able to push or roll it. I was barely able to get out of an intersection today (Nov 11), and rolled into a parking area on Oct 30 with the same fault. After about a half hour, vehicle could be moved but would show the fault shortly afterwards, locked up. Vehicle was towed on Oct 31 to dealership, they checked fault codes, performed some software updates and test drove 4 miles. They returned the car. Today, same thing happened. Car was at an intersection. Called AAA and still waiting for them to schedule a tow truck (required wheel lift and dolly). Fortunately I was on back roads today but this is a serious problem which would have been much worse on a highway. Car is not drivable. Again, this is the second time in two weeks!

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. 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 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.

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.
