 I bought a 2013, used in October 2015.  I have had steering issues, the paint is flying off the car, and I keep getting mice in my vehicle.  My car does not sit, I drive it 90.2 miles per day and, the mice just keep coming.  A week ago, I paid $110 to get a dead mouse removed from my heater motor.  Took the car in for an oil change and signs of another mouse already in the cabin filter.  This past summer, in the heat, I had a really bad odor in my car, found a dead mouse in the glove compartment.  I have asked the dealership how to keep the mice out and they have no idea.  My biggest fear is one eating the wiring harness.  This issue is not covered under the extend, bumper to bumper warranty I paid $1800 for, it's considered maintenance issues.  Before this car I had an Elantra, which I drove to 200,000 + miles, never an issue.  This was my first Sonata and my last!!
