Post: I bring it in the 3rd time and now GM says its a lifter noise and they are aware of the problem but no fix is available at this time. Some of the techs at the dealer weren't 100% convinced this was a lifter problem but GM engineers seem to think it is.

Exactly the issues I have been going through. Dealer said the same thing. They weren't 100% convinced that it was a lifter issue but GM told them to stop diag and handed me a piece of paper that says they realize the problem but their is no fix available at this time. Per the bulletin the truck needs to tick past the 5-7 minute mark and make a constant noise for them to replace anything. The rapping noise is so loud in my truck I can hear it inside my house when I remote start it. I don't care what GM says but 100% this cannot be good for the longevity of the engine.

Keep in mind this bulletin has been around for a year now. clearly they have no plan on fixing this issue anytime soon.
