Wish I read this forum before I purchased my truck. I have only had it for week and have no issues yet, but looking at the AFM threads has me scared to death. I had a blazer back in 86 and many other vehicles since then.
now needed something to pull my boat and get around on the beach, so a jeep was out of the question, and thus I now have this Tahoe LTZ.

What is an AFM?
What has you scared? I have had 6 of the old new body style trucks between
My wife and myself. I have had a battery drain issue in the 07, fixed by computer. They have replaced the steering column on 3 of them(slight shake, and I have delt with same dealer for 25 years. So they look to make me happy)
A door panel replacement, a shock absorber replaced , and some recall stuff. Oh yea the nav screen went out on one. No tranny or engine issues. Car has been very reliable in all weather.
I have not burned a drop of oil in any of them. I have so much confidence in this car, I got my father one. These trucks run pretty smoothly and go pretty much where ever I needed them to go.
Every vehicle will require maintenance and will be as sound as the guys that owned it before you. If they beat on it, you may have a problem. If not then
You will have fewer problems. Nothing lasts forever and you should expect a problem or two.
But overall you will enjoy your new truck.

AFM is Active Fuel Management
The problems with the AFM system is that the AFM lifters can fail, taking out the lifters and cam shaft resulting in engine failure... cost to repair/replace can be in the thousands....
I have over 100k miles on my 07 with no issues...

thanks guys. There are so many people here who have had very expensive problems I was beginning to think I made a huge mistake.
Hoping and praying it will be a good truck and repairs will be minimal.

if you ever have the oil pan removed, have the afm shield installed over the afm valve. It will stop oil consumption issues if its installed before the oil control rings crud up. If I had one of these, it would be the first thing I get done.

I've had 8 Tahoes and Avalanches. Usually put 80,000 miles or so on them in a couple of years before giving them to my son. His current 2010 has 110,000 miles and looks and runs like new. I have never had an engine problem with any of them. My current 2012 Tahoe LTZ That I bought as a leftover in 2013 has 50,000 miles with no major problems and I just ordered a 2015. Just keep up with the oil changes and enjoy the truck.

Welcome to the forum...
I would like to add to that not just keeping up with oil changes but also regularly checking the oil level!
The owners manual clearly states to check your oil level at every fill up, I know very few of us really do it that often but it should be an item you check a couple times a month...I am beginning to believe a lot of the AFM failures are due to the oil level getting too low in engines that have consumption issues...
