2021 Ford Mustang Mach E: lane keeping assist jerks the wheel

Filed Oct 4, 2025 · Driver assistance · CO

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.

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.

I am getting a warning in the car that the front camera is failing. The warning includes an error that the front camera failed, and that the forward collision is unavailable. Each time this happens, this causes the cruise control, lane centering and lane departure systems to disengage, which means the vehicles hard brakes at highway speeds when this happens. It disabled forward collision detection when this happens. Ford has TSB for this but when I took it in for repair/replacement they said it wasn't covered by anything and charged for the fix.

After transitioning from i35 south, to Highway 183 towards Austin-Bergstrom International Airport, the auto-pilot (Ford Blue Cruse) fails, the speedometer fails, the battery level indicator fails, the instrument cluster fails, cruse control picks a random speed and struggles to keep it, lane keep assist is erratic at best. This occurs every time, and in both directions, I take my vehicle on that highway. I took a video of it this last time, and offered it to Ford. They recommended I file this report with this agency.

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.
