In a multi-million dollar study, GM quietly discovered that Dexcool was incompatible with the Nylon 6/6 that they were using in many parts of the engine and cooling system - gaskets, radiators, heater cores, etc. Rather than risk the tax credits they get from the Gov't for long-life coolant, they are quietly changing the plastics rather than the Dexcool. This is how I understand it.
