See attached statement word document for full details. I have owned this car for two years now, I purchased it in December of 2014. At the time I was commuting 120 miles daily to support a project. I was very early on the car began to jerk and shake. I retuned it first for a defective tire, defective backup sensor and unsafe transmission functionality. Kings Ford (cincinnati OH) replaced the tire (I had to pay for the tire), replaced the backup sensor (warranty) and ¿reset/updated¿ the transmission controls firmware. After this, I retuned the vehicle multiply times for unsafe transmission functionality. After about two more times of kings Ford ¿resetting/updating¿ the transmission controls firmware they finally replaced the clutches. This was at 20,000 miles. Since then I have taken the car to kings Ford two more times for unsafe transmission functionality. Each time they ¿reset/updated¿ the transmission controls firmware. Yesterday, I called Ford roadside to pickup the car and return it to kings Ford due to unsafe transmission functionality. Also, I have another faulty tire and the air handing actuators in the dash are making grinding sounds. I have had multiply near accidents due to the vehicles unsafe transmission functionality. The vehicle has disabled itself in high speed interstate traffic. I had navigate the car from the fast lane to the right shoulder without any available power. I narrowly missed a set of large commercial trucks! once at the side of the road, I had to cycle the ignition before the car would respond to accelerator inputs. There have been multiply other instances where the car fails to accelerate correctly when merging into traffic¿nearly being rear ended, certainly leading to a few road rage incidents.
My car does not always go when the gas is hit. When you go to pull out while stopped at a red light or stop sign, the car acts like it is stalling out, shakes, makes grinding noise in the engine. Has been in the shop for the issues. I've had the dual clutch replaced and module reprogrammed a few times. I was told numerous times by the Ford tech, that the shuttering is normal for this type of vehicle. This is not normal. I had other people drive my car and they also agree that it shouldn't drive how it does. I have to avoid steep hills because the acceleration doesn't always work.
