Hi. I just got my 1500 ZR2 Duramax a few weeks back. I live in Hawaii and flew to Dallas to get the truck. Drove it back to California, stopping to see my new grandson, then loaded the truck onto a ship. It took 2-3 weeks to get it here. I’ve been happy with it so far, although it did throw a P138c code yesterday. Emissions related from what I’ve read. Set up an appointment with the local dealer next week, and cleared the code myself for now. I appreciate the help, experience and knowledge of the forum.
