2012-2017 Lamborghini Aventador, if the fuel tank is overfilled the gasoline may overflow to the EVAP carbon canister. Because the canister is too close to the exhaust it may cause a fire or at minimum melt the rear grill. Other symptoms include the check engine light on or the engine stalling at idle or fuel smell. This is caused due to roll over valve found in the fuel tank filler tube not stopping the fuel when the tank is full. This problem becomes a concern or increases the risk of an accident if you rev up the engine after it has been overfilled with fuel. Lamborghini has issued a safety recall to upgrade the EVAP system free of charge. This problem affects Lamborghini Aventador Coupe and Roadsters manufactured from 2012 to 2017.
