Broad range of choices...recommendations?

I know it's a common thread, but all seem to be different. I am 74, and between 1996 and 2019,owned twelve '96 to '03 Tahoe/Silverado Chevy's, but never a newer year. None owned since 2019, just Vettes.

I am now looking for a Tahoe as a second car. High miles, up to 150k, doesn't bother me. I've found several nice '03 to '10 LT Tahoes. The AFM thing has me a bit concerned. I like the later models, but don't want a huge repair bill on something that was running perfectly one minute, and completely broken the next. Also don't want to put a cheap AFM kit on, yet don't want to spend $3,000 or more to replace valves that are just fine, and mod the system.

So...I am curious about how serious, or likely, the AFM engine-breaking issue really is. Like, one in 10, or 1 in 100. I don't expect a real number, I am just phrasing like that to get an idea of how bad the problem really is.

Thanks for reading my long message.

The newer the vehicle the less of a problem as the system became more reliable as the improvements were released. 2012-2014 are best.

The solenoids wear out at some point, just like an alternator or starter and when they do they often take out a lifter or two. Plan ahead and delete it or turn it off.

2009 Tahoe with 6.2 does not have AFM. Neither do 2007-2009 Denalis or Escalades.
