Hi Josh! The Active Fuel Management (or Displacement on Demand “D.O.D.”) causes lifter failure ultimately resulting in needing a new camshaft. Disable it at least before you experience the consequences of the failed lifter.

The earlier models had the most issues, not enough "glue" used to secure the bows to the roof causing buffeting which made people seasick. The new axles had some issues with out of round axle shafts in relation to the hub. The vehicles with 8-speed transmissions needed new fluid or had to have their torque converters replaced. Not all vehicles in the earlier years had these problems. For the most part they are very reliable if taken care of. AFM is way more reliable in this generation, offering near trouble free service for well over 100K miles.

Welcome to the Forum from NH.

Lots of knowledgeable folks here who freely share their knowledge, experiences, and perspectives. Knowledge is power.

I hope that you will become a participating member in the Forum's discussions.

If you have the money, and you want to purchase the 2015-2000 model generation, I would suggest looking at 2017-2020 trucks, just to avoid any potential early model year issues, as identified and suggested above.

And, the search tool in this Forum leaves a lot to be desired. Some folks have had better luck using a Google search and adding 'tahoeyukonforum' to their search text string to get better outcomes from the search.

Welcome, I was wondering who was going to go first this time. Still missing a few of the regulars. This is asked about once a month. LOL

Just check out the first few pages and beyond in this section and in the General Discussion section. Make sure you get ALL service records.

With that said [besides a Condenser which GM covered and was done in less then 24 hours] my 2016 5.3 Tahoe with 102K miles has had nothing but plain old regular maintenance. I bought it brand new. AFM is still enabled.

Noticed that did afm kicks in even while in tow mode. Don't think I want it enabled while towing although getting 20mpg while towing is kinda nice.
