Welcome to the forum. Issues have varied amongst many owners, but there have also been complaints of transmission woes and problems with the infotainment system. You can check out some of the most common reported complaints here.
I bought my SEL 4 motion last year in September 17. It's more than a year, and 6600 miles, but no issue so far. I had one concern about mid range acceleration (around 2000 rpm), when it used to think about picking the right gear, and was not quickly accelerating. This used to happen once every few weeks in certain situations, but it got fixed after I took it to dealer for software update, recall checks and service (oil and filter change) last month. I am not sure if software update fixed it or any tuning done on car.
My 2.0 SEL is less than one year old and just turned 10,000 miles with no problems, has a bunch of mods and is a blast to drive, latest trip was to Colorado and average fuel economy ranged from 23 to 26 at speeds from 70-85.
