Vehicle stalls while driving at low speeds and during acceleration. The engine loses power unexpectedly in traffic and may shut off completely while in motion. RPMs increase without corresponding acceleration and the vehicle fails to shift or respond normally. Check engine light is on with fuel/emissions-related codes. Fuel gauge is inaccurate and vehicle has unexpectedly run out of fuel even when gauge showed remaining fuel. The vehicle also hesitates, jerks, and feels unstable when stopping or turning. These issues have been present since shortly after purchase and have continued for approximately one year. Vehicle is unsafe to operate due to risk of stalling in traffic.

I filled up my gas tank and a couple minutes later experienced shuddering while parked so I decided to turn the vehicle off and turn it back on but it struggles to turn back on. I then drove back home and as I was driving the acceleration was going up and down and then to 0. As i stopped on a red light the car completely shut down while the light then turned green and the check engine light, battery, and oil light came on. I then turned the vehicle off and in order to start it I had to step on the gas. I made it home but have not driven it since. I noticed there was a 19S22 recall but I spoke with ford and they said my vehicle didn’t get it but it is experiencing the same issues that the recall mentioned. There is a one time replacement for the CPV but it doesn’t cover half of what the 19S22 does and it seems to be the same problem.

On Friday [XXX], I was at a stop sign waiting to turn right, when it was my turn to go my car would not move at all, forward or back, the regular lights on the dash board were still on. I put my blinkers on and had all cars go around me. I turned my car off and then back on, that's when the check engine light came on. After 8 minutes of turning the car off and on, I was able to move backwards and forwards I was able to drive. I stopped at AutoZone on the way to get my car scanned. I received a report with a bunch of p-codes. I made it home, I called Ford, they didn't have any immediate appointments. The closet Ford dealership to me says they don't work on cars over 10 years old. I made an appointment at Firestone for saturday morning, they got the same P-codes and said they were all transmission problems and recommended I go to a Ford dealership or a transmission specialists. on my way home from Firestone, first my car speed felt like it was speeding up on it's on and then my car slowed down tremendously and I has to pull over, again I put my blinkers on. After 5 minutes I was able to move again, I was close to home. My car moved so slow feeling like it would stop any time, i drove with my blinkers on and made it home. On Monday my car wouldn't start up at all. A Ford that would take my car didn't have an appointment for 2 weeks. So I made an appointment with AAMCO for Tuesday and I had my car towed there because it wouldn't turn on. My safety was put at risk because I could have been driving at normal speed and could've slowed down out of know where and a car could have slammed into the back or side of me. AMMCO says it my dual input clutch assembly, actuators, forks and TCM This is my first time ever seeing the check engine light on [XXX] Ford's TCM extended warranty expired [XXX]. I called Ford's corporate customer service for help with diagnosis and repair but they said there was nothing they could do.
