IllustrationThere’s a known recall. “2021 Mach-E models produced between Feb 24, 2020, and July 18, 2021, are at risk of the glass panels detaching or leaking.” But my car, a 2021 model, isn’t on the list. I just discovered that my headliner is stained and there’s a leak.

After recall-related software updates were performed on my 2021 Ford Mustang Mach-E, the vehicle began experiencing repeated electrical and climate control failures. The heating and defrost system stopped working, leaving the vehicle without heat and causing the windows to fog, which reduces visibility in cold weather and creates unsafe driving conditions. The vehicle has been taken to multiple authorized Ford dealerships for inspection and repair; however, the problem returned immediately after the repair. The issue was reproduced and confirmed by a second dealer. A required part is currently on back order until the end of Feburary, leaving the vehicle unrepaired for an extended period. In addition, the vehicle experienced 12-volt battery failure and slow charging after the last recall update. These issues were not present prior to the recall. There were no warning lights before the failures occurred. During severe winter weather conditions in Pennsylvania, the lack of heat and defrost made it extremely difficult and unsafe to operate the vehicle. Because of reduced visibility and freezing interior temperatures, the vehicle could not be safely driven and, due to frigid temperatures, has remained parked. I am still making monthly payments on a vehicle that cannot be reliably or safely used.

Per your instructions I'm filling this complaint due to Ford refusing to perform recall 21S42/21V712 Issued on 09-14-2021. I have opened multiple complaints with Ford Corp regarding their dealerships refusal to perform this safety recall in which the roof of my vehicle can fly off during operation. For weeks now I've been trying to get Ford to provide me with a dealership that would perform the recall as I have been refused by 5 local dealerships. Ford tells me "we can't force the dealership to do anything" and have refused to find a dealership that will do this recall and contact me. I have been attempting to get this recall done on and off for 3 years now.
The instrument panel center display fell out of the housing today.

The instrument panel center display fell out of the housing today. Keep in mind this display controls things like all HVAC, defrosting, audio, rear cross traffic camera, and is the sole access to the front trunk (frunk). It looks like two seals on the top failed. When driving slightly inclined on a hill, it became detached and was dangling. This caused immediate distraction. The screen did not break. The screen fits back into the casing but there is no mechanism to attach it without complete permanent (ie superglue).

Windshield loose adhesion from paint separation from primer. The Glass windshield in my car had a small chip occur while driving at 40 mph.. about 60 seconds later a crack appeared about 18 inch long lengthwise across the windshield. after being parked will ordering a new windshield the crack grew to 90 percent the horizontal width of the windshield. Later while having the windshield removed for replacement by the owner New View glass in a cool indoor environment we examined the windshield adhesive and found that the paint was peeling off from the primer where the glass adhesive attaches to the car. The strength of the paint or clear coat bond to the primer or car metal is not sufficient to hold in the glass as a structural part of the car body. I am a car dealer so have more windshields replaced that a normal person. It is very unusual to see this condition. I am aware that some 2021 Mustang mach e had a recall for this condition but this VIN was not included in that recall. Perhaps it should have been. The glue just peels off with the clear or paint

The side mirrors in my vehicle are motorized and set to automatically fold in when I lock the car after getting out. They rarely do this (not the issue, and they’re fine mechanically). When I get back in and start the vehicle they are supposed to automatically unfold. 1/3 to 1/2 the time they do not. More than once I have started driving in a parking lot to realize I have no side view mirrors. I have to stop and press the “fold/unfold” button to make them open. With the mirrors closed I am unable to see out them to check blind spots or look for pedestrians or other cars. I have learned to be very careful to check if the mirrors failed to unfold because of this. I have asked my dealer to look at this at least twice (most recently Monday). They can never reproduce it, both auto-fold and unfold work for them perfectly from what they say. That’s quite different from my experience. There are no errors or messages anywhere about this. My car has the most recent software (except possibly 22S41), none of the major or minor updates it has received have ever made a difference.

Ford Dealers are refusing to complete recalls 21V712 and 21V711. To quote an e-mail from O'Meara Ford in the Denver metro area that summarizes my conversations with every other dealership, "I’ve been informed that we will no longer complete the glass recalls on MACH E vehicles. Long story short Ford does not reimburse us enough money to cover these Recalls with our labor and sublet invoices, this may be why other Ford dealers are refusing to do the recalls." Ford is not guaranteeing reimbursement for the new roofs and windshields that all the dealerships need to order before doing the work because there is over a 50% chance they will break upon removal. Ford tells me they can do absolutely nothing (customer service case no. CAS-37570083-G3K5V9) and I told them they could pay more and they said they can't. Meanwhile NHTSA is also doing nothing as this is my second complaint in 2-3 months with nothing being done. I've now had four cancelled appointments from three different dealerships in the Denver Metro area.

There are two safety recalls for many Mach-Es including mine for the windshield and glass roof. Many owners are finding that their Ford dealer is refusing to do the recall work. I first attempted to get mine done in November 2021. My dealer says they still can't do the work. I have called 5 other dealers in the Denver area and I finally got on the waitlist for one dealer. The other dealers say they are unable to do the recall. I have talked to owners in other parts of the country that are experiencing the same refusal by their dealer.

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.
PE24012 · Collisions Involving Ford Bluecruise

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.

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.

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.
