2019 Ford Fusion Hybrid SE. Vehicle experienced a “Stop Safely Now” warning with hybrid system shutdown, occurring both while driving and while parked/idling, causing jerking symptoms. This puts driver and other roadway users at risk, as loss of power/propulsion can occur without warning while in motion. Vehicle also set a P0073 (ambient air temperature sensor circuit high) fault code. The ambient air temperature sensor was replaced (Ford part numbers AU5Z-12A647-B / FC4Z-12A647-A) but the underlying issue has not been fully resolved and diagnostics are ongoing. Vehicle also had a prior transmission replacement (January 2023). Vehicle has also had extreme, unresolved electrical issues: fuses repeatedly burning out, lights burning out, two horns replaced due to failure, backup camera display turning blue/failing, and dashboard warning lights randomly illuminating. The dealership has confirmed electrical issues are occurring but has not been able to identify the root cause despite inspection. Issue has been confirmed/reproduced by a dealer. Vehicle and components are available for inspection upon request. Exact onset date of symptoms is UNKNOWN, but warning lamps and jerking preceded the “Stop Safely Now” shutdown events.* problems have been ongoing since purchase of the vehicle in 2019. Ongoing still in 2016

I drive a 2016 Ford Fusion Hybrid with approximately 105,000 miles. The transmission (HF35 hybrid) recently started making a whining noise. The vehicle was diagnosed at a Ford service center as needing a transmission replacement due to failure of the transfer shaft gear assembly bearings. Issues with premature failure of the transfer shaft bearings for this transmission are well documented online and in multiple Technical Service Bulletins (TSB 14-0214, 16-0105, 17-0039) spanning several years. Previously, a Customer Service Satisfaction Program 14B07 was established to replace transmissions with this issue, for 2013-2014 model years. The program expired; however, many vehicles were produced with the same transmission issues after this Customer Service Satisfaction Program expired (including 2015 & 2016 Ford Fusion Hybrids built before Aug 2015). It is clear Ford was aware of the transmission issue when these later year vehicles were sold. I have reached out to Ford for assistance in repairing this defect but they have not provided any support. These defective bearings will certainly fail in thousands of cars currently on our roads and highways. Transmission failures are unpredictable and could result in dangerous vehicle behavior and vehicle accidents. Repair of this transmission defect is cost prohibitive for many vehicle owners and will force them to continue to drive the cars with failing transmissions. Ford, or the federal safety agency, should issue a recall or Customer Service Satisfaction Program, to repair/replace these defective bearings both for public safety and to value their customers.

The contact owns a 2013 Ford Fusion Hybrid. The contact stated that while driving at various speeds, an abnormal whining sound coming from the vehicle with the check engine warning light illuminated. The contact also stated that while refueling the vehicle, fuel would spew back out of the tank. As both failures persisted, the vehicle began to jerk and hesitate upon the depression of the accelerator pedal. The contact attempted to make an appointment with the dealer but was informed that due to a shortage of employees, the vehicle could not be serviced for months. The contact stated that while waiting for the appointment while driving at an undisclosed speed, the vehicle stalled upon depression of the accelerator pedal while at a complete stop. The "Stop Safely Now" message was displayed on the instrument panel. The vehicle was towed to the dealer and diagnosed with a defective purge valve which caused the transmission failure. The contact then received notification of the federal safety agency Campaign Number: 22V413000 (Power Train). The dealer and the manufacturer were notified of the issue and informed the contact that the recall was not related to the transmission failure. The vehicle was not repaired and remained in the possession of the dealer. The failure mileage was approximately 130,000.
