Hyundai Sonata 2016 Automatic Diesel mileage: 300 KM or more Hyundai Sonata 2016 Diesel. The car has a head gasket leak and needs repair. The engine is still running, but it overheats due to the head gasket leak. Other than this issue, everything else in it is working excellently. Regarding the body, I cannot confirm its condition as I bought the car without inspection. Mileage: 320,000 km. Price: 16,000 Riyals, final and non-negotiable.
