Summary of Safety Issue The vehicle repeatedly experiences sudden loss of propulsion while driving, accompanied by a “Stop Safely Now” warning message and various other dashboard warnings . During these events the accelerator pedal becomes completely unresponsive while the vehicle remains powered, indicating a failure of the hybrid propulsion system or high-voltage battery control system. The vehicle and video footage of the failure are available for inspection upon request. Timeline of Events January 13, 2026 – The vehicle displayed a “Stop Safely Now” warning message and lost the ability to accelerate. The vehicle had to be towed to Lehighton Ford. January 21, 2026 – Paid $866.85 for repairs including battery service, Rear Control Module replacement, and PCM harness repair. Lehighton Ford stated the vehicle was repaired and safe to drive. Within minutes of leaving the dealership, the vehicle stalled again in active traffic and had to be returned. The issue was escalated to the Ford Engineering hotline and a Field Service Engineer.

Although the dealership recorded Diagnostic Trouble Code B11D8—a fault directly related to the stall condition—the dealership later stated that no diagnostic codes relevant to the TSB were present and this component was not inspected.

I have owned this car for the last 9 years and have kept It well-maintained. For over a year, the car stalls in the midst of driving, even on a highway, leaving me the only option to find a shoulder or safe area to park. After I turn off the engine, wait for a few minutes, and turn it back on, the engine turns on just fine and I am able to drive. Lately (for about a month or so) this has been happening more frequently(every other day, sometimes twice in a short while compared to once every 3-4 weeks). A few months ago I took it to the local Ford dealership and they told me, that they would need to replace the hybrid system, with an estimated cost of $15000, which didn't make any sense as even car is not worth that much. I also called Ford customer service and even they didn't offer much and just told me something to the effect of "tough luck". I came across this post [XXX] which matches exactly with the issue I am experiencing. That particular car owner was able to get the transmission replaced by Ford, under a California law and the issue was resolved. This seems to suggest, that Ford bears the responsibility for this manufacturing fault and they should own up to it. It is not fair that after paying over $35000, for the car, the only options I am given is to either take the risk of a catastrophic accident with the car stalling in the midst of a highway (with no safe place to stop) or just junk the car. I am pleading that your department should make it a required safety recall and Ford should be required to either fix this issue, at no cost to the owners or compensate them fairly for the present value of the car.
