  1. In 2020 I purchased a new Silverado 2500HD. Vehicle has the GAS 6.6L Engine. It recently had it's second Oil Change and Service. Vehicle ONLY has 6,500 miles on it. Now it has a knocking noise when idling. I took it back tot he dealer where I purchased it. They have had it for over a week. Initially told they had no idea what the noise was. They were communicating directly with GM to diagnose the issue. As of now they have replaced engine bearings and dropped the Oil Pan with no loose or metal particles in the Oil. With all of that said and done the noise is still present and they are waiting for further instructions from GM. Just curious if anyone else has had this issue?
