2021 Ford Mustang Mach-E Driver Assist & ADAS Problems

An error message intermittently pops up on my vehicle that says, "Front Camera Fault", causing collision assistance and adaptive cruise control to suddenly stop working. This is a major safety issue, as a failure of adaptive cruise control while under operation may lead to a risk of an accident. Ford is aware of this issue and has issued TSB 23-2155, but they are treating it like a standard repair and not covering vehicles out of warranty. This should be a safety recall.

The front camera has failed and it is available for inspection upon request. The safety of myself and everyone in my car is at risk when the pre-collision assist is not available due to this components failure. Yes, it is a daily occurrence and the camera never stays on for long. A fix was attempted once by a dealer. The component has not been inspected by either of those parties. Only the dealer whom the car was purchased from. Yes, warning messages pop up every time in the car and in the phone app about the issue. They first appeared before car purchase when the dealer fixed it in early February. Then it resumed again in late February/March.

The backup camera and 360 view stopped working, and the reverse break assist is not available when placing the vehicle in reverse. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The car would intermittently give an error saying pre-collision assist not available and now this error is permanent. There is a technical service bulletin for it 23-2155 Lots of people have been complaining about this in the mach e forum https://www.macheforum.com/site/threads/front-camera-fault-pre-collision-assist-not-available-errors.18710/page-69#post-1026803 This causes people to drop out from the automatic driving bluecruise without notice and adaptive cruise control becomes unusable.

There are many reports of the Mustang Mach E "accelerating unexpectedly." This usually happens in parking lots or other situations involving low speed and a rapid turn of the wheel. I know exactly what the problem is, because it happened to me this morning. While parking in my parking garage, my car rapidly accelerated uphill and I only narrowly avoided hitting a wall. Here is why: There are two interconnected problems. The first is that the "cruise control on/off" button is located on the far left of the interior of the steering wheel, which makes it easy to accidentally press when doing a sharp, quick one-handed turn of the wheel (like when parking). When this happens, CC engages while in the act of parking. This is exactly what happened to me. I accidentally hit the button while doing a sharp twist of the wheel, I saw the CC engage, the car rapidly accelerated uphill without my foot on the gas pedal, and I would have hit the wall in front of me if I had been a split-second slower in hitting the brake. The second problem is that there is supposed to be a failsafe for accidentally activating CC at low speed, BUT IT DOESN'T ALWAYS WORK. Page 224 of my manual says "Press the button to activate system. When the system activates, the set speed is equal to whichever is greater, the current vehicle speed, or 15 mph...." This part is true, and this is how the unexpected acceleration to 15mph occurs when parking. But the manual continues: "If the speed is too low, or other conditions are not correct for adaptive cruise control activation, the system enters standby mode. When you are below 15 mph ... adaptive cruise control does not activate unless you are following another vehicle." This is FALSE. This did not work. Clearly the CC mistook the wall in front of me for "following another vehicle." And so, when I accidentally activated CC while parking, it lurched forward UPHILL to 15mph toward a wall a few feet away. Ford needs to move the button and/or fix the failsafe.

Going over any bump in the road greater than 2 inches in heigth causes the following: - Front Camera Fault Service Required message - Pre-collision Assist inoperative - Adaptive cruise control inoperative

I was driving on the highway when the car gave me an error saying that the front camera is faulty and the collision warning system was giving an error. This stopped my cruise control and lane departure settings. I had just got my car back from Ford for this issue where they replaced a $7000 computer part and said it was fixed. This issue has been happening since I purchased the car in Dec 2024.

Anti collision, cruise control, automatic braking system, and lane assist will abruptly stop working when used. Has caused multiple almost accidents when vehicle was slowing down. Vehicle has been inducted for repairs twice for this issue and same symptoms are occurring in less than 6 months

Front camera fault. Pre collision systems don’t work without it. Large online community with the same issues but ford refuses to acknowledge it’s an issue. They won’t help even if errors start happening before warranty is over. And once warranty is over they charge large amounts to fix. There is a TSB out for the issue and it seems like a pinched coaxial cable. Our safety is at stake and the number of occurrences can’t not be random.

The front camera system stopped working, so I lost access to Pre-Collision Assist—(e.g., Collision Warning, Automatic Emergency Braking) as well as all other driver assistance feature. This would occur suddenly while I was driving (sometimes at highway speeds) where I'd have to swerve during a turn while using hands-free driving. Every time I start the car now, I have a permanent error message telling me the safety systems aren’t available. I’ve tried restarting the vehicle and checking for any obvious problems, but nothing has worked. The dealer told me it’s a hardware problem with the camera or its wiring, but fixing it would cost more than I can afford ($4K+). Since Pre-Collision Assist is a key safety feature, not having it working puts me—and possibly other drivers—at greater risk of an accident. This seems to be a common issue with Mustang Mach-Es, and I’m worried about the safety impact. I hope NHTSA can look into this and see if a recall or some other action is needed.

There is a repeated front camera fault that prevents the "Pre-Collision Assist" from working, which could lead to a car accident and possible injury/fatality. It has been to the dealership many times over more than 2 years, and the issue still has not been resolved. The Ford dealer had been able to confirm and reproduce the issue. There is no consistency for when the alert appears on the car that the "Pre-Collision Assist" is not working, but it happens often.

Backing up from a parking spot it failed to give warning of pedestrians crossing. It also fails warning for lane departures or Collision Alert warnings. All settings are on the console settings for drivers assist. Warning are given too late for pedestrians and Auto crossing while backing up. Forward collision warning does not work at all.

Front Camera Fault & Pre-Collision Assist Not Available. Vehicle displays these warnings every time a speed bump is driven over. These warnings take over the screen leading to distracted driving.

I frequently get front camera fault warnings from my car and then it disables the adaptive cruise control and the collision warning and assistance features. I have attempted to fix this and the Ford dealer held my car for about 14 days (also damaging it twice). They attempted to replace the module but could not get the new one to work and then opted to put the old module back in and apply a software update. There is a TSB for this issue to replace the coaxial cable that goes between the camera and the IPMA module. For some reason the dealer did not opt to replace this cable after attempting to replace the module. There are a large number of reports of this problem on Mach-E forums and Reddit and clearly a recall is necessary because dealers are not adhering to the TSB (perhaps to wait out warranties). They're also not providing loaner or rental cars as required as a way to discourage consumers from having their vehicles repaired (while keeping vehicles for a long period of time). A recall would resolve the fact that that this is a serious safety and quality issue and protect consumers who are out of warranty. The fact that I'm continuing to get these errors after two weeks of service is disturbing. I'm including a copy of the TSB and the detailed error message from the FordPass app.

What component or system failed or malfunctioned, and is it available for inspection upon request? Front Camera Fault; pre-collision assist; Adaptive cruise control not available How was your safety or the safety of others put at risk? I can get into a car accident and injure myself or others Has the problem been reproduced or confirmed by a dealer or independent service center? Yes Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? unknown - this is a well known issue multiple owners reporting on message boards and Ford has not done a recall Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes warning light came on and functions don't work

I am the owner of a 2021 Ford Mustang Mach-E and have experienced repeated failures of the front-facing camera system, which directly impacts critical safety features such as automatic emergency braking, lane-keeping assist, and adaptive cruise control. When the camera fails, these safety systems become unavailable or behave unpredictably, putting my safety and that of others at risk. The issue began around 40,000 miles. It is typically preceded by dashboard warnings such as “Front Camera Fault” or “Driver Assistance Features Unavailable.” I paid out of pocket for a repair at an authorized Ford dealership, but only four months later, the exact same issue happened again. Now, Ford is requiring me to pay for the repair again, despite this being a repeated safety-related failure of the same component. The dealership confirmed the problem both times, and the front camera module is still available for inspection if needed. Ford has refused to cover the cost under warranty or acknowledge any broader defect. I am also aware that other Mustang Mach-E owners have reported similar failures online. Given the recurring nature of the issue and the impact on critical driver assistance systems, I believe this is a serious safety concern that warrants a formal recall and investigation by NHTSA.

On multiple occasions in the past 5-6 months (~40, see attached photo), we have received this error which disables the forward collision detection and inactivates the collision avoidance. ERROR: Pre-collision assist not available sensor blocked

The car detects changes in speed limits, presumably with cameras. When that happens an and cruise control is on, the car will change speed automatically. However, it often thinks “65” is “85.” Thus, sometimes, the car will unexpectedly begin to accelerate very fast. This poses an obvious risk: the car is speeding up a lot, past the speed limit.

Car reports Camera Fault; forward-facing camera no longer working and adaptive cruise control, lane keeping, emergency braking and collision avoidance systems are all no longer available.

When driving two errors occur randomly and repeatedly. 1) Front Camera Fault, and 2) Pre-collision Assist inoperative. If driving with using any of the ADAS features, the car immediately begins to slow rapidly although each time it has occurred there has been no obstacle present. In one instance, it was on a freeway at 75 mph speeds nearly causing a severe accident due to the unexpected rapid deceleration. Luckily this was at 10pm at night. Had it occurred during higher traffic volumes I can almost guarantee there would have been a multiple vehicle collision. Researching online, it appears that the manufacturer has issued a TSB 23-2155 acknowledging the problem exists, but they do not see this as a significant enough safety issue to warrant a recall. When the failure causes complete disconnection of all ADAS features and the vehicle to attempt unneeded, unexpected, and unpredictable evasive maneuvers, I believe this to be a significant safety issue. The warning and attempted braking by the vehicle occur on a daily basis.
