You may have a crack in the oil tank or an improperly plastic-welded seam on the tank. The replacement tank is reinforced and more heavy duty in that regard. You can purchase just the tank and transfer the oil pump assembly. Talk to your dealer plus ask if there is a software update for your motor.
