We have had nothing but problems with our 2011 Hyundai Sonata. Less than a year ago our engine completely died while driving the vehicle. The dealership replaced the engine and since then we have had starting and electrical problems. When we went to pick up the car it didn't start right away and they told us we needed a new battery. We bought a new battery and about a week later it still wouldn't start on and off. Since we had the engine replaced, we have had to change the headlights and brake lights 4 times! we believe that when the engine died it caused an electrical issue. Fast forward about 9 months and now the car has 3 engine codes. P0017 p0014 and p0560. Crankshaft and camshaft position sensors and a system voltage malfunction. We will never buy a Hyundai again! they claim they totally replaced the engine but now I wonder if they salvaged old parts in the new engine and what exactly happened to the electrical system when the car shut off while driving.
