GM to cut powertrain warranty to 60,000 miles

GM has been aggressive about recalls since the ignition switch issue and these have no doubt cost money. Personally I will give up that mileage if I know a safety issue is covered pro actively and off warranty. I feel the general drive train quality is very good and warranty failure is rare. What does fail are rubber inter cooler boots -water hoses and belts -wear parts affected by heat. Not warranty anyway after the 3 year.
