Yup just saw this while researching this issue I now have at my local "trusted mechanic" because it blew up on me just this morning on the highway. Got a warning "oil level low, turn off engine". I pulled over, popped the hood and engine smoking from oil all over. Dumped my 8 qrts all over the highway. Mechanic even took a pic of the oil cooler line busted. For the entire lines, assembly, etc it's running me about $1400. I'm sending an email over to GM based on your below details. Should I call too to put in a case or await the long ass email reply?
Thanks in advance as this is the exact issue I have currently.
