I had a '15 Focus with the 2.0L DI I4 as well. The engine was great, got around 38 - 40 mpg highway, but the dual clutch transmission was absolute trash. I traded it back in at 35K miles after an abysmal transmission fluid UOA. The report indicated the DCT fluid had become extremely abrasive. Not all DCTs had this problem, but many of them did. I can't remember is Ford ended up settling the class action or if it's still going on.The late model Focuses..had a '15 model bought new used for daily driving got excellent mileage w/that smooth DI 2.0L . Never burned oil & sold it w/146k mis running very well. I regret sellin it now w/current gas prices! The dual clutch tranny in mine performed just fine. Most ppl didn't understand the workings of an auto dual clutch in my opinion. Still tons on rds!
