What owners say about the fuel/propulsion system

Verbatim from NHTSA complaints, newest first
“While driving the vehicle at 60 mph in traffic, all propulsion was lost and the car displayed "stop safely now." Fortunately, I had enough momentum to drift to the side of the road, but this was a very unsafe situation. The vehicle was towed to a dealership where they diagnosed the high voltage battery to have experienced a sudden failure. The vehicle has approximately 60k miles, and searching online indicates that this is a common problem at this mileage. The replacement batteries are jow only built to order, so the vehicle has now been out of service for over 2 months while waiting on a replacement battery.”

“The current recall issue already happened to my vehicle in 2022 and I had to pay out of pocket to have the entire engine replaced. I have contacted ford to get reimbursed for this due to the recall and they have not responded. Also this recall has been in place since 01/2024 and still no fix.”

“After working on [XXX], my vehicle made it home, and wouldn't start. After jump starting, I began to drive it to the dealership. My safety, and others, was put at risk when the car began to smoke, lost power in a driving lane, and then burned down with extreme intensity. The dealership isn't helping. Ford said their Office of General Council is still looking into it, but originally denied my claim before saying they would reconsider my case. An official report from the Lakeland Fire Department stated mechanical failure and loss estimated to be equal to $10,000. The engine light blinked on the way home, the oil lamp went off and on, and then the car wouldn't start. These were the only signs prior to a total loss of power and smoke before my life was in jeopardy.”

“My vehicle has had 3 Evap Canister Valve Recall repairs since 2021, I purchased my 2018 Ford Focus Titanium brand new in January 2019. I have all receipts. I recently had the 3rd Evap canister valve repair January 15,2025. My vehicle had pending codes P144A and P1450 which would have prevented it from passing Texas Emmissions. My Vehicle has also had a Transmission Control Module Recall repair -TCM twice, once in 2022 and 2023. My car has had intermitten stalling in the middle of a intersection due to this recall putting me at risk for an accident. My vehicle currently has a pending code P2867 which is the TCM code. I have AAA tow truck history of my vehicle being towed to Classic Ford for these repeat repairs. I have taken my car to Classic Ford several times in Galveston, TX in which they have not successfully repaired these recalls. Which has turned into repeat repairs. Invoices to prove it. Cook Ford in Texas City recently repaired the 3rd Evap Canister Valve on January 15, 2025 in which they also found the faulty code for the Transmission Control Module. This is a serious concern.”
