I had a 2011 Tahoe with the 5.3/6 speed and a lifter went bad around 160k miles. Mobil 1 and frequent changes since new. Cheaper to put a new short block in it than repair the lifter. Replaced it with a 2018 Yukon Denali with the 6.2 and 10 speed - significantly better drivetrain. Have 154k on that now... Knock on wood no drivetrain issues to date. Can't say enough about the 6.2/10 speed combo, gets 21 MPG on highway and plenty of power.
