Sensors constantly list as failed. Makes the automated functions unusable. Paid for these features and they don't work over half the time. Also the JUN 30, 2026 recall is still not fixable. That's nearly 5 months of no serviceable fix. Manufacturer Recall Number26S50 the federal safety agency Recall Number26V417 Recall StatusRecall Incomplete, remedy not yet available

I am reporting a recurring safety defect involving my 2023 Ford Mustang Mach-E Premium. The defect appears to involve the high-voltage battery system, powertrain system, and High Voltage Battery Junction Box (HVBJB). The vehicle and related components are available for inspection upon request. My vehicle experienced failures on May 28, 2026, June 25, 2026, and October 1, 2026. Prior to each failure, the vehicle displayed "High Voltage Battery Warning" and "Powertrain Malfunction/Reduced Power" messages. Following these warnings, the vehicle became completely inoperable and would not start. This has now occurred three times, indicating a recurring defect rather than an isolated incident. This defect created safety risks for both myself and others. During the first incident on May 28, 2026, the vehicle became inoperable while in the drive-through lane of a busy coffee shop. Because the vehicle could not be started or moved, it blocked access to the drive-through during peak morning and lunch periods, forcing the business to temporarily close the drive-through lane. This created a traffic obstruction and left me stranded. On all three occasions, the vehicle became unusable without warning, creating the risk of being stranded and unable to safely rely on the vehicle for transportation. The vehicle was taken to a Ford dealership after each incident for inspection and diagnosis. Despite multiple service visits, the issue has not been permanently resolved, and the same warnings and failure conditions continue to occur. The vehicle and components have been inspected following each incident; however, no repair has successfully corrected the problem or prevented it from recurring. The repeated occurrence of High Voltage Battery Warning, Powertrain Malfunction/Reduced Power, and HVBJB shutdown conditions that render the vehicle unable to start raises serious concerns about the reliability and safety of the vehicle. I am requesting that the federal safety agency investigate this defect.

While I was driving the brakes did not work. I had to slam on the brakes in order to stop the car. The back portion of the car then skid. The following warnings were sent to the phone and appeared on the dashboard as well. There were more on the dashboard but since I was driving I focused on trying to maneuver the car and not reading the dashboard. Not knowing what happened I continued to drive to duplicate the issue. The brakes were consistently only working when slamming on the brakes (and skidding). There was no traffic, allowing us to rely on driving slow speeds and letting the car to come to natural stops. We took it to the dealership immediately who were unable to duplicate. They diagnosed it as a network overload and attempted to release the car back to us. Currently working with a Ford Advocate as a Network Overload will shut our brakes off again. It's just a matter of when. Which is why they can't duplicate it. They can't predict when the Ford Network that communicates to the MachE braking mechanism will overload again.

After stopping the vehicle to run an errand, the vehicle locked up. The steering wheel would not turn. The vehicle would not shift into any gear. The vehicle was inoperable and I found myself stranded 25 miles from home. The vehicle was towed to our local Ford dealership where it has been for the past two weeks. This failure could just as occurred on the road causing a dangerous situation.

I have taken my car to the dealership is three different occasions and reported problems with the screens (they go black, even when driving), rear-view image missing, proximity sensor malfunctioning (beeps even when there are no objects or cars around) and the driving assistance system (constantly disengages and reports it, without intervention). Additionally, I've read that the recalls talks about a possible lock-out issue that could put my children well-being at risk and I'm aware of issues with the doors of the vehicle. Despite the multiple reports and trips to the repair department these problems are still present and this last time my car has been retained at the dealership for over a week without any update or ETA for fixing the problem and I'm being told my only option would be get a new car and start my financing all over

When the "High voltage junction box" malfunctions it can leave you stranded in an unsafe situation. Ford has been replacing them but the new ones also fail. A more robust HVJB should be demanded to avoid putting the public at risk.

I was driving along the road at 35 mph when the vehicle lost power and refused to accelerate or keep speed. The cluster flashed a warning indicating "Stop Safely Now", so I pulled over and came to a stop, and I shifted to P. Thereafter, the vehicle shut off and would not start, continuing to indicate to "Service Vehicle Now", as well as additional new errors, including "Service Powertrain", "Full Accessory Power", "Collision Assist Unavailable", and at least 8 other errors that would not go away. Two red lights were indicated on the cluster - one of them looks like a car with a "!" through it, and the other is a wrench. The vehicle is charged every night to 95% using a Level 2 CCS charger directly to the vehicle's charging port, no adapters. The vehicle had 91% battery remaining when this occurred. About 20 minutes after the incident, while waiting for a tow truck, the vehicle went completely dead and all components were unresponsive. The ignition would not activate, the doors would not open, and the open doors would not properly shut (the electronic catch mechanisms were not catching the door to keep it shut). I could not activate the screen to put it into Emergency Tow mode. The vehicle has 17,999 miles and was purchased brand new in September 2023 with 0 miles.
