I'm on the 6th week with my 2016 duramax in a dealers garage waiting on a particulate filter. It has 80k miles. Its my work truck with anvil and power tools mounted to the frame and bed. My business is going down the drain, I've never been so frustrated in my life. Customer service is nonexistent. Its my 3rd and last duramax. Where the hell is the part I need to get back on the road? Are we living in a 3rd world country? COME ON!
