 Up until today, I would have told you I was pretty pleased with my Sonata. However, with 85K miles my engine is dead. Driving to work today, the engine started knocking, the check engine light came on, and about 5 seconds later the car just died (while I was driving.) I was fortunate not to be on the interstate, and was able to coast to a safe side road. I am the second owner, so the 100K warranty doesn't transfer to me. I contacted Hyundai Customer Care, and they said sorry, but what do you want me to do about it. The cost to replace the engine is $5700. I will now have a loan for my car, and a loan for my engine. I have read on other sites that the 2011 won Beware of the Clunker Award.
