  1. Yes that's the exact sound. I had a GM rep come and listen to it and he said that's how they sound now but to confirm it he called a GM engineer who did confirm it. Said the motors are quieter in some aspects now and some sounds like the thumping/knocking are more pronounced. I find it very annoying but not much I can do about it.
  2. Yes it's a deeper thumping sound that is heard. It's harder to get it on an audio file to hear the true sound but it sounds like you can hear it. In person it's very noticeable. Yes i hear the injector tick which you can hear on all diesels and I actually like it. LOL The thumping is obnoxious, I own a RV dealership and my service manager was a Chevrolet service manager for years and worked at the Chevy dealership for over 20 years in different capacities. She stills has connections with the GM reps and has a call into him about it. She's never heard a diesel motor sound like this so not sure what to make of it. The warranty will cover anything that goes wrong but for 77k you would think it wouldn't sound like it does. Also this is my 5 diesel and when i was in the waste business we had 100+ diesel trucks, most large trucks but again I've never heard a diesel sound like this and not have an issue. Thank you for your time, I greatly appreciate your help! Please keep me posted if you should hear any info on this. Kenny
  3. That could be a contributing factor, thank you for the info.

  5. This is my 5th diesel and none have ever sounded like this with the loud knock, and my 2020 does. I can't believe they changed anything from 2019 to 2020 that would cause this obnoxious knocking sound.
  6. It's not the ticking noise as described in the bulletin, its a knocking noise. I'll try to record it and post it.
  7. I just joined the forum to see about the knock i hear. It is faint at first start up but as the engine heats up it gets louder.
