1. A fuel system of a vehicle, the fuel system comprising:
a turbocharger including a compressor disposed on an intake line of an engine, the compressor being configured to selectively compress intake air supplied to the engine;
a canister connected to the intake line via a purge line, the canister being configured to capture fuel vapor discharged from a fuel tank;
a purge control valve provided on the purge line, the purge control valve being configured to open or close the purge line depending on a pressure of the intake line;
a check valve provided on the purge line, the check valve being configured to block movement of a fluid from the intake line to the canister; and
a controller configured to perform control such that the purge control valve is operated in a closed mode to prevent intake air in the intake line from being introduced into the fuel tank when it is determined that the check valve has broken down during driving of the vehicle.
