I recently saw an article indicating 5.3 engines have a lifter issue. There is suppose to be a service bulletin on the issue. Free repairs!

My coworkers 2021 5.3 just came back from the dealer with the same issue and had all the lifters replaced. His dash lights all lit up like a Christmas tree as well.
