Ive had the same exact issues with our 2012 focus. The gas issue was the wiring harness to the purge was shorted out. As for the trans at 9,xxx miles they had to replace the seals and clutchs, which the dealer wasnt willing to do untill ford legal was involved after my many unresolved trips to the stealership. So far with about 300 miles on the car it is shifting normal, but we have lost almost 5 miles per gallon on our average since the trans was fixed. This is an on going unresloved issue so far and overall I would say were are very disatisfied with this car and the whole dealership experience. We are currently working with ford to have them buy this car back.
