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.
car still idles but does not accelerate while in motion
While driving in the dark (only) my traction light comes on. During this time, while I am driving, the car fails to accelerate. It will lose all momentum. The car never shuts off. I have to remove my foot from the gas and reapply it, for the car to correct itself. Very scary. I drive on the highway everyday to and from work. sometimes it does it repeatedly, giving my car a "hopping" feeling. It does not do it every morning but at least 3-5 times a week. Some days I am worried I will not make it to work or worse get hit from losing speed.
