On 4 occasions over a 2 month period my Taurus failed to accelerate immediately due to what had appeared to be the traction control powering down the motor, minus any flashing lights etc. I would pull up to a stop sign, and attempt to accelerate and I would lose all power for approx 2 seconds and then my car would slam into gear and take off (always on dry clean pavement). I at first dismissed this issue to being a sensor going bad for the abs system. I later found that during that time same period the speed control would intermittently stop working at various places and times on straightaways or turns without regard to what speed it was set at, however this did not happen to myself but a relation who was borrowing my car on occasion. The latest issue was when I attempted to pull away from a stop light 4 nights ago and it felt like either my car was in much too high of a gear, or if I had been driving a manual transmission I would have sworn that the clutch had gone bad and was slipping horribly. I released the accelerator and placed the car into manual shift while coasting under 5mph. My Taurus lurched and slammed into first and then when I began to accelerate I placed it back into drive and it shifted fine on its own. I'm headed to the dealer later this week and am hoping to have this issue resolved quickly and easily after having found the service bulletin for this issue on here. I still don't get why this isn't a recall when so many people have had an issue, thankfully I purchased an extended warranty and I'm covered, OH and my Taurus has under 47,000 miles on it so it's not like I've got a zillion miles and this issue popped up, ugh. Good luck to all of you Taurus owners.
