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.
Engine seems to run fine as I have not noticed any other issues but the engine will sporadically shake when turning off the vehicle. I had someone tell me I should try using fuel injector cleaner and switch to BP or Shell gasoline which I have done for about two months now but the problem still happens from time to time.
