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. February 17, 2026 – The dealership attempted to return the vehicle after performing a BECM reprogramming. Upon pickup, new issues were immediately observed including near-stall conditions and hybrid system malfunction, so the vehicle was left with the dealership again. February 18, 2026 - The owner brought forth concerns about Ford’s Technical Service Bulletin (TSB) 17-0015 which identifies potential damage to the traction battery interlock harness as a root cause for intermittent stalling and "Stop Safely Now" warnings. 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. February 20, 2026 - Dealership claims that the vehicle has been test-driven for over 100 miles and is “functioning perfectly” and that a ‘battery rebalance’ was causing the issues experie

NHTSA complaint #11596882 — an unverified report by a vehicle owner.
When I first drive it with battery-only mode (about 15 miles), it is quiet. When the engine kicks in, there is a loud whining noise when driving it on the streets or on highways and even on idle. I took it to Ford dealership they said it is the transmission and they can not repair just some parts of it, so it needs a brand new transmission to the tune of $8000. At only 110k miles, I could not drive it past 15 miles of battery range.

NHTSA complaint #11564892 — an unverified report by a vehicle owner.
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.

NHTSA complaint #11539404 — an unverified report by a vehicle owner.
A low rumbling noise seemingly situated at the right front (passenger) tire started with no warning approximately two months prior; no warning lights came on, the car did not change its driving--only a low rumbling noise which increased in revolutions with acceleration and quietened with braking and when in neutral--emerged. I subsequently took the car to a local mechanic to evaluate if the brakes were failing but in his diagnosis, he thought the likely cause to be internal to the transmission--a finding now confirmed by two other mechanics, including the Ford dealership. However, in researching this issue, a Technical Service Bulletin (20-2219) outlining this known issue with the transmission of the 2013-2016 Ford C-max built before August 2015 (mine was built in April 2015) popped up, issued June 2020. My car is now marginally outside of warranty at 112,000 miles but this known issue is one that makes the car a danger to drive-both to myself and other drivers on the road-as no warning has come on, the sound is deceptively benign and yet if the transmission fails while on a highway or other fast-paced motorway, there could be a significant accident that ensues. Given that Ford is aware of this fault in their transmission builds with no prior warning to owners of these cars, this puts road safety of the C-max driver/passengers and others concurrently on the road at significant risk. I am baffled as to why this issue has not been recalled given its severity and the risk of it occurring just outside of warranty when costs to replace the transmission are exorbitant.

NHTSA complaint #11477476 — an unverified report by a vehicle owner.
In addition to the recall gears of not staying in park the transmission also shifts to early or too late. And also a few years ago before the transmission recalls and problems came to surface one time I noticed car was accelerating all by itself with the foot off of the gas. Once foot was off break it was automatically driving. Once I pulled over stopped turned off the problem went away and hasn’t occurred.
