Front camera fault and pre-collision assist not available warnings. Car is unable to use cruise control or lane departure assist or warning.
Vehicle in Adaptive cruise will unintentionally accelerate when a motorcycle is lane splitting to the right of the vehicle, causing the vehicle to accelerate towards a slowing or stopped vehicle. This puts me and other motorists at risk of a crash.
This is becoming a common occurrence with this vehicle. The power train/ front end collision sensor/ tire sensor/ air bay sensor/ drive train all malfunctioning. Ford refuses to help.
After using fast charger in Santa Rosa Ca, to 85% proceeded to freeway on ramp, getting on freeway on ramp, Message came up on screen "STOP SAFELY NOW" 2nd Message. "FULL ACCESSORY POWER ACTIVE. I pulled over to shoulder, unable to restart car. After getting started after 15-20 minutes again the same thing happen again 5 minutes later blocking lanes of traffic. Restarted after 25 minutes went to Ford dealership which was 1 mile away. Rented car and waited the next day till I called at 4;30 to see how car was and it was.

Forward collision warning constantly going on. Brought it for service and told them but still going on
While driving on the NJ turnpike I notice a grinding noise. I was using 1 pedal drive at the time. Once I disabled the 1 pedal drive. I received multiple dash board alerts and App alerts that the Mach E was experiencing a Powertrain Malfunction/ Reduced power. Hill start Assist Warning/Pre-Collision assist Not available. This happened on 8/24/2023. I drove to the dealership and left the vehicle with them to look into the alerts and grinding noise. I called the dealer the next week and was told that the front motor had failed and a replacement was ordered. I reached out today 9.18.23 and learned it was an oil leak that caused the motor to fail and that a new motor was being ordered, the original part number was replaced with the new part. I was told that it will take another month. I do not know if the part was examined by the manufacture. I my odometer was at 45,000. I was concerned while driving to the dealer that I would lose all power.
Several people with known issue of “pre collision alert” having to replace coax cables and impa camera. I am no longer under warranty and have to pay out of pocket til this becomes a recall. Cruise control will stop working when getting this alert
Pre collision assist and front camera malfunctions randomly. Dealer did a software update and has not resolved the issue. This happens at least once every time the vehicle is driven. It is out of warranty and will not be covered. This is a problem that plagues a significant amount of vehicles, I follow a mach-e group on social media and it’s a prominent issue. If you’re using blue cruise. The vehicle stops self driving abruptly.
After having my front windshield replaced due to a recall my front camera quit working properly. This happened a year ago. Since then I have had a warning come up on my dash ever time I start my car saying the front camera has a fault and the front collision avoidance does not work. Additionally this effected the following. I have no cruise control, no blue cruise, no lane keeping assist, no self park, no adaptive cruise control and no accident avoidance system functions. There was a service bulletin issued but it should be a recall as it effects anyone that has had the windshield replaced. Apparently the wires that connect the camera are ridiculously fragile and when the windshield was replaced they were damaged. I have been waiting since spring 2023 for the parts after software updates failed to fix the problem and Ford realized the problem. They are now on back order and it keeps being pushed back. The wires are clearly defective and should not have been used if they can be damaged by a windshield replacement. And issuing a service bulletin clearly shows that they know it’s a problem but they do not want to pay to fix for everyone.
The front camera system has failed. The cables need replacing, which was diagnosed by a Ford dealer. I have no collision assist, no cruise control, no lane keeping abilities, nothing that has to do with the camera in front. This is a known problem that Ford is not admitting to. All years of the Mach-E are having this issue, frequently. It has put myself and others on the road in danger by not being able to function as it should. Every time I turn the car on I get multiple warnings on the dash concerning these issues. This is not the only problem and safety issue I've had with this car in less than 9 months of owning it. Something must be done to hold Ford accountable.
It would appear that after the recall repair my car is experiencing problems that we’re supposed to be addressed with the recall. All systems are constantly malfunctioning.
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.
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 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.
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.
The car shows front camera fault disabling all collision safety features as well as cruise control.
Front Camera Fault & Pre-Collision Assist Not Available Error messages since August 2022 around the time after a recall for windshield reglue.
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.
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.
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 just want a safe car back. All features such as lane keeping, even auto-braking are now gone. My dealer is unable to calibrate the camera anymore and suggested Ford released this vehicle a bit too early. This is worrying. Thanks
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 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.
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.
Sudden failure of front cameras. Sudden loss of adaptive cruise control and front collision early detection system as well.
Front camera fault. Was periodic. Now permanent. Disables BlueCruise, Adaptive Cruise, and other camera dependent features.
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.
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.
