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 own a 2012 Ford Focus with approximately 51,000 miles. The transmission warning light came on, and I was informed by a repair shop that the transmission control module (TCM) and gears need repair. This vehicle uses the PowerShift dual-clutch transmission (DPS6), which has been the subject of a class-action lawsuit and multiple extended warranties due to widespread failures. The car exhibits jerking, delayed acceleration, and loss of power, which create dangerous driving conditions, particularly when merging into traffic or crossing intersections. Ford informed me I am outside the warranty period and refused to assist, despite this being a well-documented, recurring safety issue for which they have admitted fault in other cases. I am reporting this issue because it poses a serious safety hazard, and I believe the TCM defect should be subject to a mandatory recall. Ford is shifting the burden of a known manufacturing defect onto consumers, and this needs to be addressed before someone is injured.

My 2012 Ford SE stalls out between First, second and third gear whenever I am accelerating to 40mph. The Transmission error continues to pop up after driving for a long period of time. Whenever driving 50 mph to 70 mph as soon as I release the gas pedal, the car goes into neutral stall out & whenever I press down on the gas pedal nothing happens and I have to pull over & Turn the car off and turn it back on to reset the transmission computer. If I don’t do that and I press the gas pedal again, the car would jerk and I have to pull over immediately and the car off. I cannot press full on the gas pedal because the car would not accelerate at full speed. Whenever I put gas in the car, it won’t start right away. It would jerk and choke just to start up. It takes me a couple attempts to start the car after putting gas in order for it to start and go. Whenever I’m finished driving and turn the car off, it makes it clicking noise in the engine area for about 2 to 5 minutes and it won’t stop and it only happens when you open the front doors or when the car is completely turned the car off. Whenever I put a full tank of gas or a half tank , the car would not dry properly install out on the highway or street I can’t drive at normal speed because I don’t know when the car is gonna stall out before it hits 1,2 or 3rd gear, which makes it very dangerous to drive on the highway.
