My 2012 just did this yesterday ... no high speed, no abuse , just normal city driving , got home and right front caliper smoking... I installed new pads about a month ago, and the pistons compressed with no problem then... I drove it to the parts store fully intent on buying another ... but the problem went away ... even the parts guy said don't blow $$$$$ on a caliper till you know the lines are not causing the issue ...

don't waste your time with it ... just change it... the dual piston setup is the problem... one piston will freeze up , especially if you live in cold snowy climate... I changed my passenger side for the very problem you described mine would act up then work fine for a month or so , until one day getting on the highway ramp I tapped the brakes and my caliper locked up almost pulling me into the guardrail ... I immediately changed it after that ... that was a year ago... now my drivers side started doing the same thing this week... terrible smell of burning brakes , but I learned my lesson and immediately changed it out...
