We have a Fiesta and as we have discovered by browsing the web that others have had problems with the dual clutch transmission jumping terribly. We called and the part was on back order. Called again in a couple months after hearing nothing, and they said it was still on back order. Called today after it has been about 6 months and the service department said that they had no record we were waiting on a back ordered part. Then the service department said that the mechanic had wrote that the transmission was fine when he drove it and that they didn't see the issue needed to be fixed. However, the day we went in for an oil change, the guy said the transmission was acting up badly and needed to be fixed when the part came in from back order. Clearly this place is extremely unprofessional and doesn't care about their product.
