Disadvantages of the Hyundai G8AB engine
Although this unit is fully dependable and resource-efficient, its fuel consumption is excessive;
Catalysts can break down after just 100,000 kilometers and cannot withstand poor gasoline;
Keep an eye on the timing belt’s condition because a breakage typically results in the motor’s death;
However, the engine’s primary issue is the nearly total scarcity of replacement parts.
