I think the transmission in my 2011 Ford Fiesta is shot. I queried Ford when I had just bought the car and never heard back from them. I knew the Focus had problems, but didn’t know the Fiesta did as well. Is it only dual-clutches, or all transmissions?
It’s only the dual-clutch transmission that’s affected, and Fiestas also had the problem. I’m guessing you bought the car secondhand, which is probably why you got no response from Ford. Contact the ACCC (1300 302 502) for advice.
