2021 Ford Mustang Mach-E lane departure problems

“On August 8, 2026, my 2021 Ford Mustang Mach-E Premium experienced a serious electronic lockout. The vehicle was running, with the air conditioning and music on, when the doors locked and I was unable to regain entry. My keys, phone, purse, medication, and other essential belongings were inside the vehicle. I attempted multiple methods to regain access, including the driver’s door keypad, but I was unsuccessful. I remained locked out for approximately 7.5 hours and ultimately had to break the windshield to reach inside and unlock the vehicle. My understanding is that Ford had previously performed a recall remedy addressing a potential electronic door-lockout issue on this vehicle. I am concerned that the vehicle experienced a similar safety-related malfunction after that remedy. I do not yet know the precise technical cause and am requesting investigation. Following this incident, my vehicle experienced repeated 12-volt battery and no-start problems. When the vehicle was left at Kenny Ross Ford for diagnosis, I was later unable to get it to respond to the key or show lights or audible signals, and it did not appear to respond when connected to a charger.

“Vehicle: 2021 Ford Mustang Mach-E VIN: [XXX] Mileage: 56,005 I am filing this complaint to bring to NHTSA's attention a safety concern regarding Ford Motor Company's decision to make the Blue Cruise driver-assistance system available only via a paid subscription beginning January 2027, at a cost of $49.99 per month. Blue Cruise is a hands-free highway driving assistance system — a Level 2 driver-assistance safety technology. The hardware enabling this system was installed in my vehicle at the time of purchase and was represented as a feature of the vehicle. Ford is now moving to disable this safety feature on existing, in-service vehicles unless owners pay an ongoing subscription fee. I respectfully request that NHTSA examine whether a manufacturer's ability to remotely disable or withhold active safety technology on vehicles already in service — technology that was sold as part of the vehicle — raises concerns under federal motor vehicle safety standards. Specifically: 1. Consumers purchased these vehicles with the reasonable expectation that installed safety hardware would remain functional. 2. Ford's decision to monetize this feature post-sale, on vehicles…”

“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]”

“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.”
