Consumer Description

Car was being driven home when car started shaking heavily and check engine light started flashing. Car had been needing 1qt of oil every 600-800 miles, depending on drive (highway would go longer). Pulled off to the side and plugged in code reader - found that cylinder 3 misfired and catalyst system below threshold. Was able to get the car home. Towed it to Hyundai dealership the following week once they were available and they found a bad cylinder head and leaking cylinder. Assumption is the amount of oil it was using ended up backing up carbon buildup. Car has less than 100,000 miles on it and even with maintenance it needs a new engine.
