I purchased the car with 7,000 miles and since the beginning there has been a humming noise every time i turn the steering wheel to either side. i took it to the dealer and they told me it was a piece of plastic stuck to the control arm. the car continued making the noise only audible on a quiet night and now the car has 30,000 and humming is more pronounced day and night with only slight turn angle. the other issue is the drivers seat has a little play, felt during turns. and the last issue is the usb just stopped working
