Looking to purchase either a 2012 and up Tahoe LTZ. Or either a 2008-2009 or 2012 and up Yukon Denali/Escalade.

looking for this specific years because I read the 2012 and up have the updated valley cover to help with AFM oiling. Or 2008-2009 6.2 engine vin code “2” wasn’t equipped with AFM components at all.

Anything else I should be looking for in these? Common problems? First time purchasing a GM honestly. (Converted lol). Downside to either engine? Leaning towards a 6.2 for the 80 more hp. But idk.

Let's correct some info to aid in your searching. The L92 (VIN 8) was used in 2007-2008 and does not have AFM and is not a FlexFuel engine. The L9H (VIN 2) was used in 2009 and in some select 2010s and also does not have AFM and is a FlexFuel engine. The L94 (VIN F) was introduced in 2010 and has AFM and is FlexFuel capable too.

The AFM updates were introduced throughout production during the 2010-2011 model years and were complete by April or May 2011 if memory serves. At this point you can just do the easy updates yourself right off the bat and do the others later when needed or time permits.

Bring a scan tool and let it inspect the entire system for problems.

About a month ago there were 12 6.2 Tahoes for sale across the USA. I posted links to them on here somewhere.

Start scanning VIN numbers. I open up every ad (only 2009 Tahoe LTZs for example) and scroll down to view their VIN and then delete and move on.

For a 2009 6.2 Tahoe you are looking for 1GNK332 (4x4) or 1GNFC332 (RWD).

There are other unicorns out there such as the RWD 2008 6.2 Tahoes, the 2013 6.2 Canadian Avalanches, 2010 GMC Yukon XL SLT with the L9H and so on.

I bought a used 2012 Escalade 6.2. It is wonderful and powerful. Had a 2013 5.3 Tahoe, but the hills out West were ******* that engine. the 6.2 has no problem.

As far as features, go crazy while the pickings good. $80k+ vehicles are going for 10-$20k. It’s a rare time when depreciation has swung the other way to benefit the buyer.

The one year option that jumps out to me is the 6.2L w/ no cylinder deactivation and flex fuel in the 09 motor. Don’t forget all those PPV & Gov’t vehicles turning out from fleet use.

I’ve clocked 40k+ on our 08 Denali AWD as the 2nd owner purchasing at 96k for $19k in ‘14. The 6.2L is regularly driven hard and the trans kick down is used weekly to full stomp. It’s on its 100% original drivetrain with no rebuild, knock on wood.

The one observation I made is romping ******* the AWD will cause the engine’s main oil seal to fail. It’s been replaced 2x in those 40k+ mi. The front end is ready for new bushings as expected after 12 years. Regardless of what you go with, do the 6.2L without the cylinder deactivation then choose your platform for 2WD, AWD or 4WD.
