2021 Ford Mustang Mach E complaints

Shortly after entering the freeway on August 18, 2023, my vehicle experienced a powertrain malfunction and displayed a Service Vehicle Soon warning light along with a vehicle with an exclamation point light and a wrench light. Motive power was reduced. I received a Diagnostic Test Code of P0ADA, indicating that there was a hybrid powertrain fault. The dealer has confirmed the code and is ordering a replacement part.

Began to receive error messages stating "Front Camera Fault" and "Forward Collision Detection Fault". For a while it fixed on its own, then the messages started to become more and more frequent until now the error messages come up every time we turn on the car. With the malfunction that is happening with front camera and collision detection, it prevents cruise control from being used (which is adaptive) and forward collision warnings are not working/inactive. The lack of both of these systems presents a safety issue. The car has been taken to the local Ford dealership which has determined what needs to be replaced (the front camera and cables connecting the camera). However the parts must come from the Ford manufacturer and there is current no ETA that the dealership is being given for the parts to be delivered. When searching online for this issue, there are other owners that have experienced this and there is currently a TSB for this issue (TSB 23-2155).

Driving my Ford Mustang Mach-E has always been a source of joy, but a recent 250-mile road trip unveiled a concerning issue. The dashboard flashed an error message at least 10 times, warning of "Service Front Camera" and "Pre-Collision Assist Unavailable." Each occurrence led to the disengagement of the adaptive cruise control, stripping away my confidence that the car would automatically brake for vehicles ahead. This intermittent malfunction, combined with the unpredictability of its onset, has cast a shadow over my driving experience. It's deeply unsettling to be constantly reminded of potential risks, especially when relying on safety features that once felt so dependable. The trust I had in my car's safety systems is now tinged with apprehension.

I had my 2021 Mustang Mach-E updated with the recall software last year. In July of 2022, my High Voltage Battery Junction Box (HVBJB) still failed, giving me a service vehicle soon and SEVERELY reducing power WHILE driving. I was on the freeway and my car just started reducing speed since I was trying to pass someone and I almost hit them. I received the new HVBJB from my dealer and had been fine since. Then a couple of weeks ago, I received the errors AGAIN with this "new and improved" HVBJB that Ford said is more robust and not supposed to fail. Same thing, on the same freeway I commute (73 toll road in California). I was passing someone and the car hit me with all these errors and SIGNIFICANTLY reduced my power. Like 66% reduction. I had to get back into my lane and was able to get back a safe speed but you basically have no power to pass. This is unacceptable. I received the "new" part and yet get a failure AGAIN? On a normal commute, not at the track, accelerating to show off the EV acceleration, just DRIVING! Please make them fix this for real. My dealer said there was a new bulletin that came out after my first repair that has an updated part number, but it is not a true revised part, meaning the internals are actually differnt, it is more a housekeeping part number update due to something as simple as the sticker being in a different spot, some backend thing, etc. There has been no revision to the components that fail since they "fixed" the part back in 2022.

On Friday 8/18/23 I was driving down a major freeway and my Mach-E jolted violently. I then received a "Stop Safely Now" and "Service Vehicle Soon" message. The vehicle lost all power at this time. Being on a very busy freeway my safety was at risk and I was luckily able to coast over to the right shoulder. The car refused to "start" after pulling over however the 12v battery did work so I was able to use accessories. Once towed to the dealer I was able to confirm a P0AA2 TSB code that indicated that a conductor was stuck open on the high voltage junction box. This was supposed to be fixed by a previous recall software update that FORD uploaded to my car however that was not the case. I am now without a car for 2 weeks but more importantly I am concerned for the safety of other Mach-E drivers as I am reading that this can happen again even after a hardware fix.

Did a DC Fast Charge at Electrify America in Astoria Oregon from 62% to 87%. Used wide open throttle to pass car on mountain climbs about 4 times with in about 30 minutes of charge. When accelerating on to Interstate 5 south received the Service Vehicle Soon warning - Ford App said stop and get car towed. Continued to drive for 22 miles and made it home. Charged car to 85% on Level 2 charger and drove it dealer on Sunday morning, no issues driving. Dealer had the car for one week and replaced the High Voltage Battery Junction Box and so far the car has been fine. Dealer provided a rental car at no cost their service was excellent. However, I thought it would be best to report this incident in light of the recent news.

After receiving the remedy to NHTSA campaign 22V-412 on Aug 5, 2022 via a Ford Power-Up over-the-air update, my high-voltage battery contactors still overheated and failed on Oct 25, 2022, requiring warrantied replacement by my Ford dealer on Oct 27, 2022.

This is the second time they have to replace the HVBJB on my car . First time was on 9/2022 and now again on 8/16/2023. the car is in the shop for the same issue.

Powertrain failure- reduced/loss of power High voltage battery warning- unsafe to drive

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

Dealership said no remedy won't fix car but has recall. But when purchased nothing wrong wug car.. everything changed and the whole world is talking in my head saying weird stuff and stealing all my money and the devil acting weird and life just I go through so much and I list nand confused wtf us gong on

The contact owns a 2021 Ford Mustang Mach E. The contact stated that while the wife was driving the vehicle and approaching oncoming traffic the vehicle was stopped. Immediately after stopping the pre-collision warning activated and the vehicle suddenly experienced unintended acceleration crashing into the rear of a second vehicle and pushing the vehicle nearly 50 feet into and across the street intersection. During the incident the driver sustained an injured neck, the front passenger sustained an injured neck and fractured left wrist. Both occupants required medical treatment. Also, the second vehicle's occupant sustained an unknown injury. No further information was available. A police report was taken at the scene and both vehicles were towed to an undisclosed location. The cause of the failure was not determined. The contact indicated that the vehicle's pre-collision warning system had been serviced prior to the incident. The local dealer was notified of the failure. The manufacturer was not yet contacted. The failure mileage was 30,000.

I was driving on the highway (12) in Mandeville, Louisiana and the car (a 2021 all electric Mustang Mach E with only 13k miles) flashed a 'Stop care safely now' sign and then proceeded to power down within 3 seconds of the message. I exited (luckily I was at my exit) and felt the car lose power on the exit ramp. Three signals came up (battery - yet I was at 100% - then a turtle mode and not sure what the third symbol was) and then the car locked up - went into park, would not move or allow me to put into neutral to pull off a very busy highway ramp. I was forced to a dead stop on the ramp (very dangerous). I put on my hazard lights but cars still pilled up all around me, beeping etc. at high rates of speed. I called 911 and the police came out (took about 10 minutes during which time I had to direct traffic around me - again very dangerous) and asked that I move the car but the car would not move or even go into neutral. A DOTD tow truck towed me to a nearby Winn Dixie and then the roadside assistance towed to the Ford Dealer. The Ford Pass app send me the message attached below that said it was forcing a software update and the car would not be able to be used during this update - while the car was in drive and while I was driving it down a four lane highway! Very unsafe considering the car was connected to WIFI at home and that update could have been done at any time - not while driving. There was no notice prior to this that a software update was needed and we have it set

Erratic behavior when semi-autonomous Blue Cruise engaged. Fault may be due to failures/malfunctions in side view mirror camera modules.

Car seat “leather” burned/melted from mirror left in car for two hours. Outdoor temp was max 75° and windows are tinted from manufacturer. I am reporting because material is too flammable and worried if left longer would have started car fire.

I have been having an intermittent warning error saying my front camera is faulty and my lane assist is no longer operational. The error seemed to come and go with bumps. Here recently it has become permanent around the beginning of April 2023, and I no longer have functionality of many safety features including adaptive cruise control, regular cruise control, lane assist, crash prevention warning, automatic braking, or even regular cruise control (if I try to turn off the adaptive cruise in the settings regular cruise control still does not work), automatic bright lights don't work. I have been trying to get this resolved since I purchased the car but despite a dozen or so trips to the dealership I cannot seem to get it fixed. I've attached a screenshot of some of the dozens (hundreds?) of error messages I have received through the Ford app with the car, which note pre-collision assist is not available. It does not seem safe to have so many safety features non-operational.

The contact owns a 2021 Ford Mustang Mach-E. The contact received notification of NHTSA Campaign Number: 21V711000 (Visibility) however, the dealer refused to replace the windshield and perform the recall repair on the vehicle. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.

Pre-collision assist turns off randomly, This event disables the safety features. When in cruise control the brakes are applied.. This a happened at 65 mph. almost causing an accident. The dealer has tried many times to correct the problem and has been unable to. He has been in contact with ford and they cannot provide a repair. They are aware of the issue

All of the advanced safety features have stopped working in my Mach E The curse control does not work either the adaptive or the standard. The pre-collision system is not working, lane assit is not working. The absence of these working systems is a danger. Ford knows about this software problem with the software, however they refuse to fix the problem at there expense. The Mach E was designed from the ground up as software driven, the manufacture should be responsible to ensure that the software is up to date.

I went to start the vehicle and it gave me a red warning "stop safely now". It was already stopped and would not start at all. It had plenty of charge on the battery pack. It's been at the dealer for nearly two weeks and they have had to order the HVJBC, I believe. I am fortunate that it didn't fail while driving or parked in a place which was inaccessible to a tow truck. The forum I read recommended making a report. This seems to be an all to common problem with this car and can lead to sudden acceleration or deceleration while in motion. Had had received an earlier yellow warning for "service vehicle soon" and took it to the dealership and they assured me they had updated all the software (in the hopes of preventing the "stop safely now" problem). Obviously, that didn't work.

Unintended acceleration from a stop when pushing accelerator. Has happened 2 times in the last 2 days. I touched the throttle from a stop 2 time and it took off like I put the accelerator to full throttle (which I didn’t). Very dangerous situation in parking lots or around pedestrians. I have scheduled an apt with my local dealer.

The contact owns a 2021 Ford Mustang Mach E. The contact stated that the vehicle was previously repaired under NHTSA Campaign Number: 22V412000 (Electrical System) however, the failure recurred. The contact stated that while driving at an undisclosed speed, the park safely warning light was illuminated and the vehicle stalled. Additionally, the steering wheel seized. The vehicle was towed to the dealer; however, the dealer was unable to duplicate the failure. The manufacturer was made aware of the failure. The failure mileage was approximately 35,000.

I have been trying to get the 2 open recalls on my vehicle done since November 2021. Ford says my dealer is authorized to do the work however my dealer refuses to do the work as Ford will not reimburse the dealer fully as I was told the dealer has to outsource the work. The two other dealers here won’t do my car as I didn’t purchase my car with them. I have been talking to both Ford customer service and my dealer Windward Ford Hawaii and they both blame each other. IFord said the dealer should be able to do the work while the dealer says they can’t until they work out the payment from Ford. I just want the work done so my car is safe. I don’t think I am the only one in Hawaii that hasn’t had this recall work done yet…and it’s not for lack of trying. Please let me know if there is anything that can be done so that Mach-E drivers in Hawaii can get this recall work done.

Hood latch on vehicle failed. When opening hood to access the frunk (either thru manual hood release, or electronic release on car screen), hood unlocks halfway, and then is in a state where it can neither be opened or closed. Car has questionable safety once hood latch is in this state, as it is partially open and will not relatch. My car is currently at dealer for replacement of striker, hood latch, and actuator components under warranty.

The car shows front camera fault disabling all collision safety features as well as cruise control.

Ford released an OTA update for the HVB issue Mach-E were having and leaving drivers stranded. I have seen that even with the update many people are still having the cars break down while driving and needing the High Voltage Battery Connector replaced. I am worried that this may happen to my car one day while driving and could cause an accident or death. Is there anyway to force Ford to fix every car that had this issue before we break down? The temporary fix of software is not good. I think FOrd should be forced to recall all Mach-E and replace the connector before there is an accident that leads to deaths on the road.

Front Camera Fault & Pre-Collision Assist Not Available Error messages since August 2022 around the time after a recall for windshield reglue.

Stuck Disk Brake: The left rear disc brake was stuck. After releasing the parking brake the car would not move. After two attempts to reverse the brake released. There is a loud thumping sound from the rear wheel. While braking there is a violent vibration coming from the left rear wheel. The car is parked now and will be towed to a Ford Dealer. In the on-line Ford Mach-E forum there are other complaints about brakes being stuck with similar description as above. My car was last driven in wet weather and then parked in a garage. Temperatures at the time were cold but not freezing. The temperature at the time of incident was about 50 degrees Fahrenheit. This seems to be a safety issue.

The contact owns a 2021 Ford Mustang Mach-E. The contact received notification of NHTSA Campaign Number: 22V412000 (Electrical System) however, the part to do the recall repair was not available. The contact stated that several local dealers were contacted; however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.

Occasional failure of video signal from front camera located above rear view mirror causes Alert pop-up on main instrument display and loss of all Driver Assist feature that utilize the front camera such as: lane departure alert and adaptive cruise control.

Occasional blank/inoperative info screen, typically recovers after reset or re-start, but sudden loss of visibility of ALL settings and controls for heat, navigation, and most importantly loss of the ability to enter backup Start code for keyless start can cause possible stranding in dangerous conditions. Loss of control of heating/cooling could cause loss of visibility if defrost is unavailable, or heat stroke if air conditioning is unavailable. My understanding is that re-designed console screens are available to address this known defect in vehicles built prior to June 2022, but no recall has been issued.

While driving and hitting a bump I will get a message in the driver's display stating Forward collision assist unavailable. This causes almost all of the ADAS features to stop working including cruise control and blue cruise. This is very dangerous! There is a huge thread on this issue at the macheforum.com. The issue needs to be addressed by Ford Motor Company in a recall.

Ford has failed to take corrective action regarding their Safety Recall Notice 22S41 ( high voltage battery main contactors may overheat and remain open or weld closed). They have not supplied the program updates NEITHER by Wi-Fi or vehicle modem via Automatic Updates for which my vehicle is set up to receive NOR by way of the Ford dealership (Brewster Ford, Brewster, NY) having possession of my vehicle for THREE (3) full days. They are simply unable to remedy Safety Recall Notice 22S41 endangering my family and I. Please take whatever action that you are allowed to fixed the problem before someone gets hurt. Thank you.

The mach e has a front trunk. I have seen several posts about the front latch failing which includes the emergency release should a child or smaller adult get stuck in the frunk. My mach e did this to me today. As a result I was also forced to drive with the frunk half open to get my car back home until I can get it serviced.

After latest software updates, the Mustang MachE gets stuck in the guest profile regularly. These profiles are responsible for controlling driver aids, one pedal driving, etc. When stuck, my vehicle removes one pedal driving and the car moves unexpectedly. One pedal driving holds with no break, this is removed and the car creeps when break removed, this nearly caused the car to crash through the garage. This could injure people in parking lots, etc. There are many other driver aids controlled by the profile which could unexpectedly get disabled. I have personally figured out how to reset and recognize this after nearly crashing the car into the garage, but Ford has issued no communications to their customers on how to recognize and revert when this issue occurs. When manufactures issue over the air updates, the need to be responsible for communicating issues and workarounds to their customers directly. The dealers (any my dealer) have been useless about any software bug and just state, wait for ford.

This vehicle has an issue with persisent and now completely locked out safety systems. There's a 40 page forum on MachEForums. Currently at the dealer 2 weeks with no known fix. They are waiting on parts, but do not guarantee a fix. All of my safety systems have been disabled from this. Adadptive Cruise Control, which isn't concerning, but - Forward Collision Warning, Automatic Emergency Braking, Lane Departure Warnings, Lane Keeping Assistance. I feel unsafe in this vehicle and Ford has no current fix. A serious investigation needs to go into this as I was advised by the Ford BEV team hotline he had just spoken to someone from California who started a buyback for the same reason, and when the dealer couldn't fix it, to call back and advise it's a lemon. The fact Ford themselves suggested this and cannot restore safety systems is beyond scary. Dealer isn't convinced they can fix it and says parts are backordered, meanwhile there's no concise fix. A master tech in the thread has suggested co-axials, while others have had their camera and camera harness replaced. Others like myself are without the loss of a car for weeks while still having to pay for it. Please launch a formal investigation. If it was just adaptive cruise, it wouldn't matter. Normal cruise is knocked out as well as every ADAS feature, due to a 'front camera' / colission avoidance issue. Another tech in the thread suggested the wiring loom was not long enough causing a harsh bend to the coaxial in the bumper. I

The contact owns a 2021 Ford Mustang Mach-E. The contact received notification of NHTSA Campaign Number: 21V711000 (Visibility) and 22V412000 (Electrical System) however, the parts to do the recall repairs were unavailable. The contact stated while driving 60 MPH, he received a warning from the manufacturer app of a high voltage spike and that the vehicle would shut down. The contact exited the highway and pulled into a parking lot where the vehicle shut down. The contact could not restart the vehicle. The contact stated that there was no warning light illuminated. The contact had the vehicle towed to a dealer however, the vehicle was not diagnosed. The mechanic was able to restart the vehicle. The mechanic was unable to duplicate the failure. The contact drove the vehicle to his residence; however, the high voltage spike failure recurred. The contact had the vehicle towed back to the same dealer. The contact was informed that there was damage to the battery metal shielding on the passenger’s side, toward the center of the vehicle. The dealer stated that there were two holes and determined the damage was due to the vehicle striking an object. The dealer stated that since the damage was caused by the vehicle operator, the NHTSA Campaign Number: 22V412000 (Electrical System) could not be performed. The failure mileage was approximately 7,000. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repairs. The manufacturer was made aware

The contact owns a 2021 Ford Mustang Mach-E. The contact stated while in reverse(R) and driving approximately 3 MPH, the vehicle would independently brake suddenly. The contact stated that the parking brake light was illuminated. The contact stated that the brake failure was intermittent and occurred without warning. Additionally, the contact stated that the vehicle would lunge forward while stopped at a traffic signal without depressing the accelerator. The vehicle was not taken to the local dealer; however, the local dealer was contacted, and the contact was asked if she had duplicated the failure. The contact stated that she could not since the failure was intermittent. The vehicle had not been repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 21,000.

* On October 16th, 2022, at about 7:00 pm, I was driving my 2021 Ford Mach-E GT when we began to change lanes (we were in the left lane heading East) as the vehicle in front of us slowed down to make a left-hand turn. There was a car behind us and two vehicles in the right lane (two-lane road in each direction) that were a few car lengths behind us as we began to change into that lane. When I turned on my signal and turned the steering wheel, I pressed the gas pedal to accelerate to get around the car in front of me to keep my distance from the vehicles in the lane I was transitioning into. Unfortunately, when I pressed the gas pedal, we experienced complete vehicle failure. I had no steering, brakes, or acceleration. Within a short time (30-45 minutes), we had no power as the lights on the vehicle, and all electrically powered devices and components were entirely out. This made it very difficult to tow the car as it is all-wheel drive, and we could not put it in Neutral to pull the vehicle. As this happened, five cars were in the area, and several had to swerve and fly off the road onto the dirt shoulder. We barely missed the car in front of us, and the car behind us had to lock up its breaks not to hit us. Our car gradually slowed down and cost off the road about 50 yards or so after losing power, as it was very difficult to get the vehicle to steer; it took everything I had to turn the wheel to get it off the road. We put on the emergency blinkers, but the vehicle lights f

Pre-Collision Assist Not Available has been persistent since purchasing last month. There is 27 page thread (https://www.macheforum.com/site/threads/front-camera-fault-pre-collision-assist-not-available-errors.18710/page-25) recommending that we file a report here.

I keep receiving a fault for the front camera which seems to be a very common occurrence amongst Mach-e owners lately. After receiving this message, the cruise control abruptly kicks off. All functions of the cruise control do not work in this instance…adaptive, speed keeping, lane control, etc. This fault happens about once every couple of minutes while driving. When I’m using cruise control in ‘one-pedal’ drive mode and this fault occurs, the vehicle immediately starts braking. This happened one time as I was entering a narrow bridge in Solomons, MD, and a car behind me nearly rear ended me.

I have had a camera fault error for several weeks. This leads to the pre-collision assist and other features not being available. The camera module has already been replaced once and I still have the same problem.

Sudden failure of front cameras. Sudden loss of adaptive cruise control and front collision early detection system as well.

The contact owns a 2021 Ford Mustang Mach-E. The contact stated that while her husband was driving slowly into the garage and the vehicle suddenly experienced unintended acceleration and crashed into the home and went through to the bedroom, causing damages to the vehicle and the home. No warning lights were illuminated. The vehicle was taken to a local dealer for an unrelated recall repair and the contact made the mechanic aware of the failure. The mechanic confirmed that there was no related recall on the VIN. The vehicle was not diagnosed. The contact was concerned about the safety of driving the vehicle and was referred to the manufacturer for guidance. The contact filed a claim with the insurance provider and the vehicle, and the home was repaired. The manufacturer was made aware of the failure and a case number was provided. The approximate failure mileage was 2,335.

Car purchased new June 2021. In April 2022, I began to get intermittent faults regarding the front camera “Front Camera Fault - Service required” - this would disable cruise control on highways and cause quite a lurch and change in speed. The error message disables cruise control, camera, pre-collision assist, and lane keeping assist. The error message would disappear after a few minutes. By Memorial Day weekend May 2022, the fault was persistent and the error message did not go away. In August 2022, I left the car with my dealer for 3 weeks and they did some software updates and re-seated my windshield to address an open recall. Since then, I have received the front camera intermittent fault three times. There’s quite a number of us with this issue and Ford has initiated buybacks due to the problem being unresolved. We just want the issue resolved, as it’s a safety issue.

Front camera fault. Was periodic. Now permanent. Disables BlueCruise, Adaptive Cruise, and other camera dependent features.

HVBJB failure, vehicle lost power and threw an error “stop safely now”; will not drive

Starting approximately in June 2022, my vehicle receives almost daily faults. It will generate a "Front Camera Fault" and a "Pre-Collision Assist Not Available" message. When the car generates these faults, the following other features will fail to work: Adaptive Cruise Control, Normal Cruise Control, Automatic headlights, Lane Centering, Pre-collision warning. I brought the vehicle into two separate dealers on two separate occasions to address the problems. Both times, parts were replaced, software was updated / reset, and camera systems were re-aligned. None of these efforts have even made the problem any better. The fault will sometimes appear when first starting the vehicle. But, sometimes the fault will appear at highway speeds which causes the car to disengage cruise control suddenly which is jarring and unexpected.

The contact owns a 2021 Ford Mustang Mach-E. The contact stated that while her mom was driving, the vehicle accelerated without warning. The electrical system was inoperable. While the contact was driving at low speed in a parking lot approaching a stop sign, the vehicle accelerated. The brake pedal was applied but the vehicle continued to drive and crashed into a Toyota 4 Runner. The air bag deployed and impacted the driver in the face and she sustained knee injuries and cuts on her stomach and blood in her stool. A police report was filed. There were no reported fires. The vehicle was towed to an independent collision center. The vehicle was taken previously to the local dealer where the hardware was updated and a reboot was completed. The vehicle was repaired but the failure persisted. The manufacturer was not contacted. The failure mileage was unknown. The VIN was not available.

The Adaptive Cruise Control will arbitrarily reduce speed for no apparent reason. This has happened on several instances. Sometimes the vehicle just slows down and other times the brakes are suddenly applied. The vehicle speed has been suddenly reduced by 20 MPH on a busy 65MPH road in rush hour. No accident occurred. Vehicle was in service just this past month. All updates were entered and several flaws were corrected. Problem has continued up to and including this morning. No warning lamps or collision avoidance alarms were triggered.
