Dex-cool is not the cause of the problems in GM cars. There are plenty of GM cars and trucks out there with no cooling system related problems.
The intake leaking problem is caused by a combination of...gasket design and material, low torque clamping forces of the bolts, expansion and contraction rates of the manifolds.
Some things to remeber about Dex-cool is to make sure you use a 50-50 mixture, fill the overflow jug to the hot level, replace the radiator cap
