There are many reports of the Mustang Mach E "accelerating unexpectedly." This usually happens in parking lots or other situations involving low speed and a rapid turn of the wheel. I know exactly what the problem is, because it happened to me this morning. While parking in my parking garage, my car rapidly accelerated uphill and I only narrowly avoided hitting a wall. Here is why: There are two interconnected problems. The first is that the "cruise control on/off" button is located on the far left of the interior of the steering wheel, which makes it easy to accidentally press when doing a sharp, quick one-handed turn of the wheel (like when parking). When this happens, CC engages while in the act of parking. This is exactly what happened to me. I accidentally hit the button while doing a sharp twist of the wheel, I saw the CC engage, the car rapidly accelerated uphill without my foot on the gas pedal, and I would have hit the wall in front of me if I had been a split-second slower in hitting the brake. The second problem is that there is supposed to be a failsafe for accidentally activating CC at low speed, BUT IT DOESN'T ALWAYS WORK. Page 224 of my manual says "Press the button to activate system. When the system activates, the set speed is equal to whichever is greater, the current vehicle speed, or 15 mph...." This part is true, and this is how the unexpected acceleration to 15mph occurs when parking. But the manual continues: "If the speed is too low, or other conditions are not correct for adaptive cruise control activation, the system enters standby mode. When you are below 15 mph ... adaptive cruise control does not activate unless you are following another vehicle." This is FALSE. This did not work. Clearly the CC mistook the wall in front of me for "following another vehicle." And so, when I accidentally activated CC while parking, it lurched forward UPHILL to 15mph toward a wall a few feet away. Ford needs to move the button and/or fix the failsafe.

My 2021 Ford Mustang Mach-E (142,009 miles) intermittently fails to accept a charge at public DC fast-charging stations. My husband relies on these stations because our home electrical panel cannot support a home EV charger, and he uses this vehicle daily for his work in commercial real estate, often needing to charge it twice a day while traveling throughout Southern California. We first brought the vehicle to Tuttle-Click’s Capistrano Ford (San Juan Capistrano, CA) for this issue, and were charged $250 for a diagnosis and software-related repair (Invoice XXX, dated XXX). The technician’s notes state the vehicle would stop charging after about a minute at DC fast chargers, that the code P0EEE:27 was stored in the SOBDM module, and that the battery was manually charged to 99% and the code cleared. Ford refunded the $250 after the same problem recurred shortly after this repair. When we brought the vehicle back in a second time for the identical issue, the dealership informed us that Ford currently has no fix for this defect, and that only a Level 1 or Level 2 AC home charger can reliably charge the vehicle — which is not an option for us since we have no home charger installed. The dealership subsequently provided us with a copy of Ford’s own internal Special Service Message, SSM 55080, titled ‘Stop Charging When Using DC Fast Charger Level 3 With DTC P0EEE:27 And/Or P2E53:27 Stored In the SOBDM Module.’ This bulletin confirms Ford is aware this defect affects 2021–2023 Mustang Mach-E, 2022–2025 E-Transit, and 2022–2023 F-150 Lightning vehicles, that replacing the charge port hardware will not resolve it, and that a software fix was targeted for Q3 2026 — a deadline that has passed without a working fix reaching our vehicle. This defect leaves us with no reliable way to charge the vehicle away from home, directly impacting my husband’s ability to conduct his work.

In mid-November 2023, the authorized Ford dealership Hutchinson Ford of Forsyth, located in Forsyth, Georgia, sold and installed four Toyo A23 tires (size 225/55R19 99V) on my 2021 Ford Mustang Mach-E. After approximately 23,000 miles, the tires experienced catastrophic premature wear. Upon investigation, I discovered the dealership had installed tires with a load index of 99. The manufacturer's required specification for my vehicle is a minimum load index of 103. This incorrect fitment created an 880-pound deficit in the vehicle's total load-carrying capacity, posing a severe and constant risk of tire failure, especially at highway speeds. This is a critical safety issue for a heavy electric vehicle. The dealership's management has acknowledged the danger. When I raised this issue, the service manager stated they were "glad something bad did not happen." Despite this admission of the risk they created, they have refused to correct the safety issue, claiming the premature failure is normal wear as the tires are "nearing end of life." This constitutes a dangerous service practice by an authorized Ford dealer, which knowingly left a customer's vehicle in an unsafe condition. I am filing this complaint to document this safety issue and the dealership's refusal to rectify it.

The panoramic roof glass panel is not properly bonded/sealed to the vehicle body structure, allowing water to leak into the cabin on the driver’s side. The vehicle and the failed component (roof glass/moulding) remain available for inspection upon request. This creates a safety risk consistent with the one described in NHTSA Campaign 21V712000 / Ford Safety Recall 21S42, which covers 2021 Mustang Mach-E vehicles with inadequate panoramic roof glass panel adhesion to the vehicle body structure — a defect that, per Ford’s own recall filing, creates risk of the roof panel separating from the vehicle while driving, increasing the risk of a road hazard, injury, or crash. My vehicle exhibits the water leak symptom associated with this defect, but my VIN was not included in the recall population. The first visible symptom — staining on the driver’s side rear headliner — was documented in a photograph dated XXX, with continued staining documented in a follow-up photograph dated XXX. The vehicle was presented to an authorized Ford dealer (All American Ford of [XXX]) for inspection on XXX. The dealer confirmed the water leak and documented the driver-side top moulding as faulty, with the roof panel requiring replacement. The vehicle was also examined through a BBB AUTO LINE arbitration proceeding (Case #XXX), which acknowledged the existence of Safety Recall 21V712 in connection with this vehicle’s file. There were no warning lamps or dashboard messages associated with this failure; the only symptom has been visible water intrusion and headliner staining.

While driving my 2021 Ford Mustang Mach-E, the front electric drive unit failed suddenly with no warning signs, warning lights, unusual noises, or any prior indication of a problem. During the failure, multiple fault messages appeared on the instrument cluster, including warnings that disabled adaptive cruise control and indicated the all-wheel-drive system was no longer functioning. The vehicle began to vibrate severely, feeling as though it was driving over rumble strips. As I slowed down, the front of the vehicle became extremely clunky and exhibited abnormal drivetrain behavior. Shortly afterward, the vehicle became undrivable and could no longer be operated under its own power. It had to be towed to a Ford dealership, where I was informed that the front electric drive assembly had failed and required replacement. This is the second time this exact component has failed on the same vehicle. The first front electric drive assembly failed at approximately 33,000 miles and was replaced under warranty. The second failure occurred at approximately 102,000 miles with no warning. I believe this repeated and sudden failure of a critical drivetrain component presents a significant safety concern because it can leave drivers stranded without warning and results in an unexpected loss of propulsion while operating the vehicle in traffic.
