Oh Bugger .
Has it done anything like this before? or any others?.

Old Faithful is a guyser, not a volcano.
No, but old faithful sits directly on top of the largest volcano in the world.

I would suggest a faulty catalytic converter, but if its still under warranty then take it back to the dealer and make them fix it.
Specifically, it appears that this access road in Yellowstone National Park overheated and started to melt after hot oil built up below it and eventually worked its way towards the surface and came in contact with the asphalt.
“Extreme heat from surrounding thermal areas has caused thick oil to bubble to the surface, damaging the blacktop and creating unsafe driving conditions on the popular, scenic road, located off the Grand Loop Road halfway between Old Faithful and Madison Junction in the park’s Lower Geyser Basin.”

From April 9 to 13, 2015, scientists will be using Ground Penetrating Radar (GPR) to map what lies below the ground around Old Faithful Geyser. Team members will be visible walking off the boardwalks around the cone of Old Faithful.

Blue/Gray Smoke:
Blue/gray exhaust smoke is an indication of oil burning in the combustion chamber. These are possible symptoms and causes: Valve Seals: Leaking valve seals will cause blue/gray exhaust smoke. Valve Guides: Excessive clearance between the valve stem and the valve guide allows oil to leak past the gap into the cylinder. Piston Rings: Worn or damaged piston rings will cause blow-by, resulting in blue/gray smoke. Worn Cylinder Walls: Worn cylinder walls cause blow-by, resulting in blue/gray smoke. PCV System: A stuck closed PCV valve causes excessive crankcase pressure, resulting in blue/gray smoke.
Black Smoke:
Black exhaust smoke is an indication of a rich fuel condition. These are possible causes: Fuel Injectors: A leaking or dripping fuel injector will cause a rich fuel condition. Fuel Pressure Regulator: A stuck closed fuel pressure regulator will cause a rich fuel condition. Fuel Return: A restricted fuel return line will cause a rich fuel condition. White/Gray Smoke:
White exhaust smoke is an indication that coolant is burning in the combustion chamber. These are possible causes: Cylinder Head: A crack in the cylinder head (around the coolant jacket) will cause coolant to enter the combustion chamber. Engine Block: A crack in the deck of an engine block near the coolant jacket will cause coolant to enter the combustion chamber. Head Gasket: A damaged or blown head gasket will cause coolant to enter the combustion chamber resulting in white/gray smoke coming from the tailpipe.
Exhaust Color Diagnosis
Black smoke is caused when the mix of fuel and air inside the engine becomes un-balanced. Normal mixture is 14.5 parts air to1 part fuel. When the fuel to air mixtures change because of a malfunction the mixture can go as high as 14.5 to 2 or 3, two to three times the proper amount. The black smoke seen from the tail pipe is the excess fuel generated from the rich mixture. Malfunctions in fuel delivery or a leaking fuel pressure regulator will cause black smoke to be produced. The fuel injection system atomizes fuel by pushing it through a small nozzle of the fuel injector while under pressure. The computer system measures vacuum and air flow into the engine intake manifold to determine a proper amount of fuel that should be released. Airflow is controlled by the throttle body or throttle valve actuator (throttle) as fuel is distributed directly in each cylinder. The process of measuring the amount of fuel a fuel injector is dispersing is determined by the PCM (powertrain control module - computer).
