Must be the luck of the draw. We are on number 3 with no problems on any of them. My wife put 120,000 miles on hers with no repairs, only tires, brakes, and oil changes, before trading it in for a Ford pick up she wanted. I put 15,000 miles on the 2014 SE I bought last October with no shifting problems before trading it in this spring for a 2015 SE hatch with a sunroof.
