“My vehicle is subject to open NHTSA recall 25S76 regarding a fuel injector that may crack and cause fuel to accumulate on top of the engine near hot surfaces, creating a fire risk. This recall was identified months ago, but Ford has stated parts are not currently available and no repair date has been given. I have not received any further communication or updated timeline since the recall was issued. In the meantime, my vehicle has also been experiencing intermittent jerking during acceleration between approximately 40-50 mph, which I am concerned may be an early symptom of the injector issue described in this recall. I am continuing to drive the vehicle because no remedy is currently available, but I am concerned about the extended delay in providing parts for a safety recall involving a known fire risk. I am requesting that NHTSA review the length of this delay and Ford's plan for remedying affected vehicles”

“The contact owns a 2021 Ford Bronco Sport. The contact stated that on several occasions the vehicle lost automotive power while driving and while stopped and idling. The check engine warning light was illuminated. The contact stated that after refueling, the vehicle required several restarts before continuing to drive. The vehicle was towed to a dealer to be diagnosed, and the contact was informed that the battery was prematurely draining and that the EVAP was clogged, and that the battery and EVAP needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was 35,000.”

“On 9/15/26, while actively driving with my child, the monitor screen suddenly turned black and an error message of "Vehicle Network Communication Error", a few seconds later my dashboard turned black, no display messages, speed limit, or manual gauges were working and that too went blank; blinkers did not work when trying to use them. Luckily I was a short distance from where I was traveling to and when we arrived I turned off my car to see if i restart it, it would reset my car. It did not work. My car did not turn on, did not crank- the light on my start button just flashed rapidly. It was not until after my husband later arrived he disconnected the negative battery terminal and let it stay disconnected for 20-30 minutes and it then restarted. Case #CXH-09342591-W5K1G2 was filed with Ford Customer Relations, but they said further information regarding the case would likely not be provided to me as an update.”

“The vehicle's entire powertrain and transmission system failed completely. The vehicle will not turn on, will not start, and the electronic rotary gear shifter is physically locked out, refusing to shift into Park or Neutral. The transmission assembly component is currently available for physical inspection upon request. The sudden loss of powertrain and electrical control module communication caused an immediate loss of motive power, stalling the vehicle and leaving it completely stranded and un-drivable. The physical lockout of the shifter mechanism prevents rolling or shifting the asset safely, creating an immediate rollaway or crash hazard if stranded on an active roadway. The car was also jerking vilolently in the middle of an intersection almost causing an accident where we would’ve been rear ended. Yes. The failure was formally diagnosed and confirmed by an authorized dealership, Jim Taylor Ford in [XXX], under Repair Order (RO) #XXX. The component has been physically inspected and diagnosed by the certified technicians at Jim Taylor Ford dealership, who confirmed a total internal failure. They have ordered an entire replacement transmission assembly…”

“I had recalls for body control module and power train control module calibration updates. i took it to my ford dealership on august 12th, 2026 they had it done with within the day i picked it up. within a week after (i don’t drive my car much just to work mostly) i had an error come up on my dash saying the powertrain control had failed and i was unable to put my car in park. i immediately called the dealership they asked me to bring it back in. they ended up giving me a loaner vehicle and was with out my car for 2 weeks before I called and asked for an update. they said they were so sorry the transmission was compromised and i was going to have to pay 11,500 for a new one. I had never had issues with my transmission before bringing it in for my recalls to be addressed. i am still without my car and figuring out what to do next.”
