Default GM Dex-cool

Has anyone heard about the class action lawsuit by many people nationwide against GM and others concerning Dex-cool coolant causing problems, like leaking intake manifold gaskets and overheating. I was at a local radiator shop having a friends radiator flushed and he handed me an article about it. This was the first I had heard about this and was wondering what any others may have heard.

I havent had any problems with it other than my intake gasket, only eating about 1/2 coolant bottle every few months.

So which of those is the most relevant about the law suit?
My 3800 II runs dex-cool, I have not had any leaks yet close to 90K miles, but it is not a nice thought, since so many HAVE had problems.

Dodge uses a similar Dexcool coolant. Took the Caravan to have the oil changed; they topped off all the fluids. Although the reservoir had a giant warning label to not add regular coolant, they did. It also created a mess and the coolant turned into sort of mud. The van started to overheat and it cracked a cylinder head with only 6,000 miles in the odometer. It was a big event to make the shop repair the van until they were legally threaten. They wanted to just replace the head gaskets; I had them replace the whole engine with a new unit at the dealership.
