Have seen the recall notice on Sonata 2011-12. I have a 2010, manufactored in alabama. The motor went out in the car a few months ago while I was driving. It lost power and stopped. The car continues to sit in my driveway. I had the dealer inspect it before it went out because of a knocking noise. The dealer (mungenast Hyundai, 649 dunn rd. , st. Louis, mo) reported it was a motor problem and the only way to fix it was to replace the motor. The warranty had already expired, and I did not have $5000 to replace the motor. The motor problems did not start with the 2011 models. I hope you can look into this, and hopefully I can get my vehicle repaired. Thank you.
