This vehicle has had consistent transmission shudder and engine rattle upon acceleration which affects the the initial acceleration of the car. The sporadic delay in initial acceleration has been an ongoing safety concern. Most recently the vehicle almost stalled completely after beginning to accelerate into a merge. There was a few second delay in any movement or power to the car. Luckily there was no one coming at the time or this vehicle malfunction would have caused a serious accident. My car has been in to a Ford service center 5 times for this complaint and it is still not resolved. I am also concerned that Ford knowingly replaced the clutch and seals in my car with malfunctioning parts. Apparently newly engineered parts were produced as a patch for this issue. Either the old parts were used to fix my car, which would be quite an egregious safety issue, or the newly engineered parts are still malfunctioning. Either way I do not feel that my Ford Fiesta is safe to be on the road and Ford has not adequately address this issue to resolve the matter.
