Hyundai Sonata GL 2011 Automatic Gasoline mileage: 300 KM or more Peace be upon you. Hyundai Sonata 2011, clean. Two days ago, a sound came from the engine. My friend told me it's a crankshaft sound, and the engine needs replacement. Of course, the car is running. Whoever wants it as is, is welcome. Renewed, inspected, insured, ready for transfer. May God provide for us and for you from His abundant grace.
