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.
The turn signals do not turn off as expected. Instead they blink 2 x going the opposite direction! This definitely causes confusion for the driver and the cars following you! It makes you seem like an idiot because as you try to turn off the blinker, it keeps blinking 2 x in the opposite direction!!!! Technicians have not found a cause or resolution. They just chalk it up to user error, which it is not! Its just another quirk that I've had to live with since I've had this car. At first I didn't really pay attention to it, thinking it was user error, and then as I became more aware of the times it happened, I was assured that it was the car at fault and NOT me.
