sorry to hear about your car, i work at a ford main dealer and often we get jobs that are not simple and do drag on for days before we get any progress, the car may have been there for 6 days but no way has it been worked for that amount of time, 8 hours a day. always get pulled off jobs and onto others and jobs get put to one side for abit, since the car is new i wouldnt say it going to be a simple fault. get onto ford customer services, explain how you have only just got this car, prob the second most expencive thing a person could buy its been in the dealer for as long as you have owned it, do this for a few days and they should send a field tech out to the dealer to assist in the diag
good luck
