For the last 4 months the car has been shuddering and hesitating when moving from a full stop (as you tend to need to from a stop sign or red light or a parking spot!). I complained about this when I brought the car in for an oil change and I was told that's a common problem. When I brought my car in for its 15K service I again complained and was told I could schedule a transmission check and there may be reprogramming that could fix that. I was told at the end of the service that my 14 month old car had an oil leak. Service Rep said maybe the oil was leaking on the automatic trans clutches. I brought the car back the next week at a scheduled appointment armed with the relevant Ford Service Bulletin TSB 14-0047 that covers the very problem I was having. I had read on a couple of boards that Ford is reluctant to authorize the warranty repair of replacing the clutch ($3,000) but only replacing seals and cleaning the clutch results in the car having to come back. I don't blame the dealer so much, but Ford did refuse to allow the replacement. The car is running better now, but not as much pep as the Fiesta rental I drove for a few days that had more mileage than my car on it. We'll see what happens.

Update from Aug 17, 2014: At 16,364, the repair (initial part of TSB 14-0047, clutches cleaned and not replaced) lasted the evening after I picked up the car and the same shuddering and acceleration problems began to occur the very next day. Over the next few days the problem got worse than ever and I even almost stalled going up a hill. Car sounded like it has a bad carburetor and I felt like I was back in my mother's old 1984 Ford Escort.

At 17682, I brought the car back and had the full TSB 14-0047 repair including replacement of the clutches. Car returned to me driving like it was supposed to. That last barely a day and it started going bad again. I am back to where I was before. Have to reach back out to Ford to see if there is anything that can be done. Bottom line, as the service repair person said, they haven't perfected the design of this dry transmission. Doesn't seem like this repair is going to make the difference and I am stuck with a bad transmission.

Update from Mar 10, 2015: I returned to Ford not long after the full repair and this time they refused to even test the transmission. They insisted that this is just the way the transmission was designed and it was supposed to do that. They announced to the service agents at large that it was a mistake that I wasn't given the special Ford instructions that tell me that the transmission is supposed to shudder, jerk, hesitate and generally suck. It was I who needed instructions on how to drive and accept their design flaws.

Now, the transmission hesitates when accelerating from a full-stop and then shoots forward. I rear-ended someone in heavy traffic because of it. The Ford dealer won't event hear my concerns or complaints.

Been dealing with the rattling almost from day one. Finally took it in to the dealership. They kept my car for a few days and then told me to come pick it up. Not only is the front end still ratting, but now the ncylight is on, the oil light is on, and the tire pressure light is on. I'm tired of this. Naturally, the rep from the dealership is saying the rattling is normal but I know for a fact the type of noise coming from the front end is not "NORMAL>" I'll give them one more chance, but if I continue to have this problem, I'm contacting Georgia's Consumer Protection Agency.

Had these issues and was told they changed the throttle body in the car. lifted the hood this morning and nothing had been moved, my antifreeze was down to about 1/4" and it was supposed to have been serviced, and the oil filter looked like he had not been changed. I called another ford place and he was very familiar with the issues that my car has and said they first Ford place lied, if they changed the Throttle body that doesn't fix the trouble. Has nothing to do with it. So, they didn't change that, didn't service my car as i paid them to do and kept it for 3 days the 2nd time. don't think i am not going to blister someone over this. i will be writing my letter to the manufacturer to have my bases covered for lemon laws.

Took it in to the dealer for it to be fixed, they weren't sure what was wrong. I told them I went to take off down an on ramp and the car almost died and then all of the sudden it picked back up and took off. The engine light came on. I got to work and they came and towed it in. They say they changed the wiring under the dash and windshield. I asked how they knew to change that and I got the response that it had been that before. I pick it up and no more power than i had when i dropped it off. But they say they drove it. Whatever.
