On certain vehicles, the check valve for the purge control system could wear and cause the fuel tank to expand. As a result, the fuel tank could contact hot components and fuel could leak.
Safety Risk
A fuel leak can create the risk of a fire.
Corrective Actions
Hyundai will notify owners by mail and advise you to take your vehicle to a dealership to inspect and, if necessary, replace the check valve and update the electronic control unit (ECU) software. The dealer will also inspect the fuel tank and surrounding components and repair them, as necessary.
