We've had our 2011 Sonata SE for like 3 weeks. Tonight we came out from Wal-Mart and when I pressed the Start button the engine got stuck in some kind of loop for 10-15 seconds. It did not start but was "turning over" repeatedly like it was attempting to start. Finally it just quit. I again depressed the brake pedal and pressed Start. This time it started normally. This is very, very worrying to me on a brand new car. Anyone else seen this?
