Disadvantages of the Hyundai G8AB engine

  • This is a completely reliable and resource unit, but its fuel consumption is too big;
  • Catalysts do not tolerate bad gasoline and can fall apart as early as 100,000 km;
  • Monitor the condition of the timing belt, as its breakage is usually fatal for the motor;
  • But the main problem of the engine is the almost complete lack of spare parts.
