 From the moment I purchased this car (which is an automatic) there was a shuddering when you stopped  at a red light or stop sign and accelerated after the stop.     When I finally called in August 2015 after I told them what the car was doing it took me two months to get in to have them diagnose the problem because as I was told this was a problem with this model.  Once I got it looked at in October 2015 I was told it was the clutch as they had suspected.  They returned the car to me and I was told 4 to 6 weeks to get the part in.     In middle to late December 2015 I called to see if the part was in and NO.  I was number 30 on the list (so there are 30 cars before mine that are waiting on this part)       Called in late January 2016 to see about the part and NO part for my car yet I am number 23 on the list.  In the meantime I continue to drive this car which shudders and sputters every time I drive it wondering if this is going to be the time that it will shudder and sputter until it dies and I am left stranded.     Call a 1-800-392-3673 number I was told to contact to see why I cant't get this part for my car.     This is a KNOWN problem with this car.  Google it and you will be amazed at the problems they have with this car.     I can't believe Ford isn't manufacturing this part faster than this so this can be repaired and that they continue to sell this car (It's just not with this model year.  If you go online it with this model in general).      This is the first Ford I have ever purchased and you can count on it that it will be the last.           Customer service by Ford in manufacturing the part and getting out to the dealership (at least the dealership I am dealing with keeps telling me they are getting about 3 parts per week from Ford) so these repairs can be made is terrible.    I am truly disappointed that I purchased this car.
