Ford Mustang Mach E lane assist problems

Filed Sep 22, 2026 · Driver assistance, Electrical · CA

On almost all Mustang Mach-E vehicles, a loose or faulty cable connection which runs to the forward facing camera in the rear-view mirror housing causes error messages to suddenly display on the dashboard screen. Generally, the driver will receive a "Front Camera Fault – Service Required" error message, in addition to a "Pre-Collision Assist Not Available" error message, also followed by an error message indicating that lane centering is also no longer functioning. All of this occurs after the vehicle travels over a harsh imperfection/bump in the road pavement, or in my case, every time I drive over railroad track crossings. I have seen so many reports of owners receiving this exact same issue, and everyone says the same thing: when this issue begins to occur, the vehicle will disable all of these safety features for about 30 seconds or less, and then all of the systems will reactivate like normal. Many owners state that eventually these errors become permanent, which causes all of these safety systems in the vehicle to become PERMANENTLY disabled, until the vehicle is brought into a dealership service center. If the vehicle is still within the 3-year/36,000 mi factory warranty, Ford will replace the coaxial cable running to the camera at no charge to the vehicle owner. However, as many owners have stated, if their vehicle is beyond the factory warranty, the vehicle owner usually is forced to pay for the repair out of pocket, which seems to range anywhere between $1,000 and $4,000. The reason I am reporting this matter is because I believe this is a major safety concern. When the front camera fault appears on the driver's display, the vehicle automatically disables many of the safety systems, including the ability for the vehicle to avoid a collision by bringing the vehicle to a stop. Because this is a major safety concern, I believe that NO Mustang Mach-E owner should be forced to pay for this repair out of pocket, and I believe that this should be a recall.

Ongoing issues with forward facing radar preventing collision assistance and adaptive cruise control along with lane keep assist from working. Ford knows about this. There is even a TSB. A car manufactured in an era that requires collision prevention should not be allowed to have significant camera faults that prevent safety systems from functioning properly. Unfortunately, the plan for many is to continue operating without these important safety features and crashes will occur as a result. Ford should be required to properly fix their radar system functionality in the Mach-E.

My car displayed a warning that the pre-collision assist was not available. This caused all of the safety features not to work (collision warning; lane departure warning; parking collision warning etc.) The car has been in and out of the dealership since Aug. 6th to repair this but Ford has not corrected the problem. We have not been told what is wrong with the car or any estimation on if or when it will be repaired. I requested the service documents for all of the records of when my car has been in the shop for this issue. I received the document but it has incorrect and missing information which causes me to be concerned that the issue is not being address but instead my car is being held with no efforts of a remedy. My car has not operated correctly for almost 2 months but the only service recorded was a replacement of a coaxial cable which did not fix the car.

Camera system that allows hands free driving, lane departure warning, collision warning and adaptive cruise control fails and all system offline. Extremely widespread on the 2021 models. Looks to be a cable route to the camera that was installed incorrectly. Went to dealership, they said they see this in almost all of the Mach E vehicles. Usually begins failing when hitting bumps -- system goes in/out. After a while, system drops out completely and all safety systems relying on them fail.

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.

Some of the driver assistance warning systems may not be operable due to multiple and frequent warning messages. Messages are: Front Camera Fault Service Required; Pre-Collision Assist Not Available; Lane Keeping System Fault Service Required. Ford is unable to correct these making it potentially unsafe. Additionally, they are not covering the attempt to fix this under the extended warranty. There are hundreds (if not thousands) of owners of the same model and year of my car, and subsequent years as well, having this issue with no resolution. There needs to be a recall.
