 We purchased the 2012 Ford Fiesta SE (Auto) in August of last year. Since we have put on over 33,000 km on it. Never had a issue with until last week. While accelerating there seemed to be a slip or clunk in the transmission and there would be no acceleration for a very brief period of time. We also started to notice a dramatic drop in our MPG. The first 8 months of use we would get around 650km per tank of gas on a mixed driving terrain. Now we are lucky to push 425km per tank. Dealer says it was the ATC and said it is fixed now. We will see. I really hope the gas consumption gets resolved.
