2012 Chevy Equinox catalytic converter

Chevy Equinox

My catalytic converter has melted so says the garage.

Was there a question in there? The converter typically melts internally if there is un-burnt fuel exposed to it during operation. For example, if one of the cylinders of the engine was not firing and allows the fuel to simply pass through. When this happens there is usually a rotten egg smell that accompanies the situation.
