- Ford Mustang Mach E Premium
After 7 tries over three dealerships and 9 months with this problem, I believe my 2021 Mach-E is now finally fixed. Not all dealerships are created equally - they are really just franchises after all, and full of humans with all the various trappings that entails.
As mentioned on this thread and others, I agree that in most cases, this problem seems to be caused by poor design in the way the coax cable is routed to the camera in the wiring harness. Coax cable is not really designed to be subjected to sharp bends. It may have been an issue waiting to happen, or as I suspect, the problem was created or exacerbated during the windshield replacement after the recall for the adhesive. Over multiple visits, typically the car would spend time at the dealership, and then I'd pick it up, in most cases having the problem reoccur sometime on the drive home. Most times, but not all, it would be in reaction to a bump in the road. Some people here have been able to recreate the issue by pressing on the headliner near the camera itself, but not me. It could last for seconds, or up to 10 minutes. At one point it became permanent as there are a finite number of times it can be reported before it sticks. After that module was reset, it went back to being intermittent.
The fault would of course never show up for the dealerships, who seemingly on principle would ignore my suggestion/request to look at the wiring to the camera itself, instead wasting lots of time reprogramming or replacing modules that didn't need it. Much time was spent waiting for components to arrive.
As I had been dealing with the issues for so long, with the car spending almost as much time on dealership lots as my driveway, the car was in for its last time before the buyback procedure would have started. That was when a Ford tech eventually gave the dealership the go-ahead to replace the wiring harness. The wrong part arrived twice, but after installing the 3rd one, I've had no recurrence in almost one month and 1000 miles. I'm hoping this continues, but at least now I'm able to go back to the same dealer and tech to replicate their previous fix if it happens again. Hopefully, Ford will redesign this aspect of the car for the future as it seems to be a weak spot for a number of people reporting this.
Ford customer service is very busy but were helpful to me with rentals etc.
Happy to relate further details of my experience to anyone suffering with this.
Have you had any more issues with your car since you made this post? I've been having the same issue for months with my 2021 Premium. I've been to the dealership 3 times (total of ~30 days). The techs have been following the same protocols and have even attempted to replace the camera. I'm not sure they're having luck figuring it out just yet but if this is the fix that would be great news!
