I drove a 2011 Tahoe 5.3 liter. with AFM about 150 thousand miles, then I drove a K2 Tahoe with a 6.2 engine for about 110 thousand miles with active AFM, now on the T1 there are already about 40 thousand miles on the odometer with active DFM. There are a lot of friends who have K2 generation Tahoes and Escalades with over 200 thousand miles on them, without any problems. Moreover, there are people with disabled AFM and dead lifts, and there are those with active AFM, but the lifts work without problems. My personal opinion is that the problem with lifts does not depend on AFM and DFM. But, the problem with lifts does not happen suddenly. They become audible, they begin to knock noticeably. So if you listen to the car, you can replace it in advance. I have a friend who basically changes lifts every 60-70 thousand miles. and it already has over 200k miles on it. Also an option for solving problems.
