Heard it from another that two new Duramax 3.0's have blown up in our area with less than 300 miles. Overheating supposedly. Not sure how that can happen without some royal screw up, but I have to treat it as rumor till I hear otherwise. This friend of mine loves to shoot the bull at dealerships and makes a great mark for salesman, as he tends to trade often, trouble is I have no idea who told him and no way to confirm. Or maybe he just misinterpreted? Also, If this is in the wrong forum, feel free to move it.
