Many 6.5 engines including mine have siezed because of a quick disconnect on the oil line to the cooler that wears out and pops off. The damage is done before anything is apparent. GM has known about this for years and done nothing to warn owners. This is a $10,000.00 repair.

I do agree none of the other manufacturers are any better. Their responses are determined by the potential for negative financial impact, and have nothing to do with right and wrong.
