New to the site and the duramax. Well, as the title states I have a 2011 LML with a broken crankshaft. Truck is bone stock with 133k miles. Is it just me or is it rediculous that this happened? The truck is sitting at the dealership now. Waiting to hear if GM is going to help with the repair costs. I've read of quite a few of the older models having this issue but they usually have a tune or a ton of miles. Is this issue going to continue continue into the LML line of engines?
