CarComplaints.com Notes: The 2011 Sonata has a seriously defective engine that seizes without warning. It was awarded the dubious honor of being the first CarTalk / CarComplaints Turd of the Week in late September 2015.
A class action lawsuit was filed in May 2015 against Hyundai that claims the 2.4L Sonata engine is defective. More info here.
This is a real hazard for anyone who has kids and drives this car. There is no way to lock the doors manually after it gets in this state. The only work around I have found is to "reboot": the car. Technicians have found no cause or solution.
