The forward collision detection system failed first. Then the car suddenly would not move and gave a pull over immediately warning on the dash and also flashed a battery light. It was 15 degrees outside and my wife and son were stuck in the cold. Not a safe environment. This is inexcusable for a car to be driving fine on minute and to be completely inoperative the next.

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.

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.

The vehicle suddenly had a front windshield camera error light up on my dashboard from just driving regularly on the road. I currently have a crack windshield which I am having difficulty to replace because the front camera sensor error codes wouldn't allow the windshield camera to be recalibrated. My vehicle is currently experiencing this exact service bulletin but since is is not a recall, my dealership charged me to diagnosis this issue for $300 and claimed to fix this issue but is currently not solved. Occasionally the front camera being faulty lights up and disappears, however I am still unable to replace my windshield due to this error.

Our vehicle would flash a "Front Camera fault service required" and a "Collision Warning not available" every now and then that started a few months ago. I had it diagnosed by the dealer and they said it would cost me $786.50 to do a major update on IPC, IPMA, PSCM, CCM, CMR, and perform IPMA Alignment per TSB 23-2040. We have to pay this because we are out of warranty. We thought all system upgrades are supposed to be free. Wouldn't this be a flaw on the Mach-e and should be considered a standard safety issue that needs to be corrected at no cost to the car owner? I saw that many owners also have the same issue. Our family including a [XXX] may be at risk because of this. Appreciate your help on this. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Front Camera Fault & Pre-Collision Assist Not Available Errors COLLISION WARN MALFUNCTION, COLLISION WARN NOT AVAILABLE or COLLISION WARN DISPLAY FAULT. Over 30k miles in the car so the warranty is over for bumper to bumper coverage. Dealer said an update would fix the issue. It cost 2k. Paid. The error came back within a day. Dealer says the next option is to replace all the wiring for the cameras. Which would be another 2-3k.

For over a year I got this warning that said pre collision assist not available. And it would go away after a few minutes. A few weeks ago it never left. Now I have that error as well as adaptive cruise not available. I cannot use my cruise control. I just recently had another issue and paid over 3 thousand. Now ford wants to give me another quote for 3 thousand. I searched and I'm not the only one with issue. This should he a recall problem as we are all having same issue.

Front camera stopped working after a long period of working intermittently (started to happen after passing warranty at 30,000 miles). Without that camera many safety features are disabled, like a front collision warning, lane departure, cruise control with adoptive speed, emergency breaking. The cable and processor issue was confirmed by Ford dealership service.

There is a permanent fault on the front camera of the vehicle, making it unavailable. This has permanently disabled the vehicle's pre-collision safety feature. The adaptive/normal cruise control is also unavailable because of this. Prior to the permanent issue, the fault would occur randomly and without warning, creating an extremely hazardous condition, especially while utilizing the vehicle's "one-pedal" feature. Under this condition (using adaptive/normal cruise control and the one-pedal function), the fault would occur abruptly and without warning, cruise control would fail and the vehicle would brake simultaneously, without driver action. Several times, while driving on the highway, this happened to me. I was fortunate enough to not get in an accident. The dealerships have been unwilling to address my safety concerns. Please see to it that this is resolved. I have seen many consumer forums with this same issue.

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.

The car is frequently but intermittently reporting a failure with the front camera: "Front camera fault Service required". When this happens, the adaptive cruise control and other ADAS are disabled, which is a safety hazard while driving the car, especially at highway speeds. This issue began very infrequently in March 2024 and now happens on the majority of trips when driving the vehicle. I took the car to a Ford service center for repair. They did a software update on the car and told me that they were sure that the update would fix the issue. The front camera fault re-occurred within a week after having the software update done.

Received intermittent warnings that the front collision warning system, cruise control and front camera were not working. The problem I think began after having my roof/windshield removed/reglued under recall. It was intermittent and I could not tell if software updates were resolving the problem, but then the problem became permanent at which time my car was out of warranty. Which does not seem fair since the problem began during the warranty period,. likely as a result of the windshield recall.

While driving I get a camera alert and a collision avoidance system is not working. Then I have to reset the system by pushing a button on the steering wheel. The car has been in for this problem 3 times since 2022 .Now the 3 year warranty is up and Ford won’t cover the repair. May dealership has been dealing with this issue on a lot of cars. I filed a lemon law suit. They are not going to repair the car or by it back. They to want to give a couple of thousand. But nobody can tell me what the cost will be to fix the car. So I am at a standstill

Vehicle receives warning message that front camera and pre collision asst is unavailable after driving it for about an hour. Vehicle was serviced following the ford directive to ensure that the service to the vehicle following the warning was followed correctly. This didnt suffice the warning and the warning continues to show up daily on the vehicle. This is a safety feature that is causing errors and knocking out any safety feature for the operator of the vehicle.

Aug 14, 2024Lane DepartureDriver assistance

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.

Vehicle received "Front Camera Fault" and "Pre-Collision Assist Not Available" warnings multiple times. This is a known issue at Ford as they have a service bulletin (TSB 23-2155 [XXX] ) on it and is widespread. There are forum posts regarding this with 64 pages of people posting about it happening to them [XXX] ). When this happens, it disables Adaptive Cruise Control, Pre-Collision Assist, and Forward Collision Warning. If you happen to be using Adaptive Cruise Control or Ford's HANDS FREE BlueCruise, the hands free system immediately stops working. If you weren't to take over when this happens, it would be a disaster. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2021 Ford Mustang Mach-e Bev Bev verdict →
