the GM guys here

Of the Yukon/Suburban's what Engines, tranmissions, years should be avoided if you were looking at one to buy?  I been looking at something to get me thru the summer and they seems to be priced pretty well for what your getting.

The years I am not sure on years But there was a active fuel management system that shut down some of the cylinders and caused a oil consumption issue.  2007- and up, the 5.3 motor I believe.   We stayed away from those, the 6.0 or Escalade or deniali motors used in the all wheel drive model did not have that system or issue

Any 3/4 ton burb is pretty much problem free (relatively speaking) and lasts a very long time. On the negative side, the fuel economy in those is not great

I have an 04 Suburban with the 5.3. It is my wife?s daily driver and now has 195,000 miles. It has never had anything other than maintenance done and an alternator rebuild. Only fluids and filters otherwise. All service done per the owners maintenance recommendations. It is on its second set of tires which are nearing the end of their life. I have no idea how they last so long. This year did not have the active fuel management. If i were to buy a new one that system would be disabled for sure.
The parts to keep these things going are cheap cheap cheap. The alternator rebuild cost less than $100. I was told by a service department in Colorado that they could swap in a new engine and transmission for $2800 each.
When it dies i will repower it. I will add a turbo or possibly do a crate motor that is much larger. I would like a 500-600 horse power sleeper. But, this thing keeps going and doesn?t burn a drop of any fluid. I have also though about shipping it to duraburb for a Duramax transplant.

This is correct.  2007 to current 5.3L engines with AFM are not as bulletproof as the older version without AFM.  2007 particularly is a year to avoid.  After that they implemented a few band aid solutions, but have not completely fixed the problem to date as far as I have seen.  It typically fails outside of warranty, so they don't care.

If you want to avoid AFM here are the options:
2006 or older 5.3L
Any year 6.0L (found in the 2500 suburban only)  At least I don't think they have added AFM yet to this engine, anyone else know about the newest ones?
2010 and older 6.2L (found in Yukon denali and escalade only)

You can get the 6.0 in the the higher end Yukon or Tahoe.  But it was rare

The suburban LTZ and Escalade have the 6.0 but they suck for towing because of the air ride suspension. I would assume the high end Yukon and Tahoe are the same.

In Detroit visiting daughter after dropping dog off in Ohio.  Driving rental Silverado with a v6 and fuel management system. Not bad, but I wouldn?t own one- average HWY mileage close to 23mpg for trip so far.  It will get out of it?s own way but I wouldn?t tow with it. Might make a good LIGHT work truck tossing light bulky stuff in the bed, but definitely not anything heavy of any substance.
