Any of you guy own 2011 to 2013 Silverado or Sierr@ . I'm looking at used in the under 75,000 mile range, but wondered about reliability after 75,000. My Tacoma is at 167,000 with no major problems other than normal wear and tear. I'd prefer to go with the 5.3.
Be cautious of trucks with the AFM. Many have had problems. I think if people changed the oil more often than they do it would not be a huge issue, but that is my theory. Good luck!

I have an 11 with the 5.3 and if wasn't for the fuel management system it would be a great truck. I had an 01 with over 200k that never had a powertrain issue.
The FMS can cause issues of misfire in the #1 and/or #7 cylinders. I bought mine used with 22k and didn't know this, I they had to rebuild the motor at 40k (under warranty, i didn't pay a dime). It's not all of the trucks, supposedly the later 11s and 12s don't have that issue as much.
I'd pull the plugs if I were you to see if it looks like oil has been burnt.

Well that is why it is a theory and not fact, lol.
Hate you have to deal with it.

'13 with 6.0. Don't have AFM. Gas mileage ain't great, but pulls the boat, ranger or golf cart well.
Had a 01 and a 08 Silverado that both had over 190,000 miles when i sold them. Still see with on the road around town today. I currently have a 2012 with over 90,000 miles going strong. Never had a issue with any of them.
I have a 2007 Silverado. 5.3 liter v8. 175,000 miles and all I've done is brakes tires and oil changes and preventative maintenance. 100,000 miles on these they are just getting broken in
'09 Silverado 5.3 & 4 spd auto with 96k............
Pretty much only normal maintenance other than a front 4wd knuckle.
I'm not positive but there is a website that you can lookup the most common problems with about any vehicle I think this is the site I found when trying to find out about my 04 3.0 v6 ranger I wish I had checked before for I bought it I would have found out about the head problems I had to repair. I will double check to make sure but I believe this is it https://www.google.com/url?sa=t&source=web&cd=3&ved=0ahUKEwjgt8C-sJPSAhWIhlQKHYXmCq0QFggOMAI&url=https%3A%2F%2Fwww.nhtsa.gov%2Fcars%2Fproblems&usg=AFQjCNEA8BxbFwbF0_IPUiOnAEpDyhd_nA
Two 96's and one with 277,000 and one with 87,000 5.7 liters and no afm, thanks .The way that works is not good.
No auto select 4x4 mode either. E85 locker rear end.
Did have the tranny rebuilt at 201 ,000 in the one.
Driving a 98 gmc with 5.0 305. I have a 5 speed in it and I guess at 199,000 miles I'll put a clutch in it. Don't use any oil and I get 23 mpg. Sadie won't let me down. Our auto tech teacher has a triton V10 with almost 400,000 miles on a gas burner. Only replaced radiator.
389,750 on my F250 5.4 triton, nicely broke in now. Last truck was a chevy 1500, 2 new trannys and needed a third by 260,000 and became scrap.
I wish I had read stuff like this thread before I bought a 2011 Silverado last Aug. Its been OK so far but I'm hearing not too good reports about the AFM system on the 5.3 engine. Has any one used one the plug in devices to shut off the AFM?
If I had to do it over, I would have waited to look for another F150 to replace my 04 with 205000. It was a good truck.

Some do take it out of the system.

I have an '08 Silverado 5.3 liter V8. Mine has about 150,000 miles on it. I change the oil regularly and have had no problems with it other than wheel bearings.
Good luck with whatever you do.
Got an 08 with 48,000 miles. At 55,000 noticed the oil being used way too much (due to the AFM). Picked up the Range AFM Delete and stopped the oil consumption. At 65,000 I wanted better performance/MPG so I got a Black Bear Tune. Have 111,000 on it now and performs beautifully. We have had several fleet trucks that are 11's with the oil consumption issue from the AFM that led to needing new lifters/pistons/rings. If you go with the 2007.5-2013, get the Range AFM delete or if it is out of the powertrain warranty get you a Black Bear Tune. Had an 03 with 146,000 miles that ran beautifully until a Lincoln Navigator took a shot at it. I hear the 14's and up seem to have gotten the AFM figured out.
I have a '99 Silverado with 210,000 and I would not be afraid to drive it anywhere. Rust ? Yea its getting pretty rusty but it has been a good one for me. In the last few weeks I bought a '88 1500 from my son,because he found a different truck he had to have,and now Im driving the '99 and the '99 is in the drive way. The 88 rides and drives like a new truck even though the odometer says 230,000. I know the motor has been changed in it but I love it and will own it for a long time.
I'll have to research the AFM issues. I don't even know what it stands for.
I've not completely ruled out an F150 5.0.
I've never been extremely loyal to any brand. In the 80's I owned an F150 that was a good truck, a Ranger that was a good truck, and a Dodge Dakota that was a piece of crap. The only new truck I ever bought was a 95 Chevy WT with the 4.3 V6 that was a great truck and I saw the guy I sold it to driving it for years afterwards. In 99 I bought a 95 Tahoe with the 350 in it. I drove it until 2008 when I bought my current 06 Tacoma. I still really like the Tacoma, but I could use the extra room of a full size pickup at this time. In addition to my trucks, we bought an 07 Expedition a couple years ago for a family vehicle that I couldn't get rid of fast enough. In fact........I almost didn't make it to the dealer with it to get rid of it and I lost some $$$ on that vehicle. It left a pretty bad impression of Ford with me (I'd have liked to have pushed it off of a cliff), but I suspect along with a known problem with that particular engine that Ford had only issued a warning on, the previous owner hadn't taken as much care of it as I'd thought.
If I do a search on any of the full size pickups, I can find at least one problem that multiple folks well swear is running wild in that particular model. That's not to diminish the problems that some of you are having, but I've about decided that just about any vehicle (especially a used one) is a calculated risk.
There is an 09 Silverado LTZ (with a topper) with 90,000 miles on it at a local dealer that looks really good. However, I'm really struggling with the idea of shelling out 21,750 (matches NADA without topper) for a vehicle with darn near 100,000 miles. Not to mention, I can find 2011's and 12's with similar mileage for just a few thousand more. But................a new one is off the charts as far as I'm concerned.
Thanks for all the info.

Active Fuel Management, they deactivate, cut the oil of to, 4 cylinders to save gas. It is turning a V8 into a V4 when the power and torque is not needed.
"Cylinder Deactivation (Active Fuel Management) System Description
System Operation
General Motors Active Fuel Management engine control system has the ability, under certain light load driving conditions, to provide maximum fuel economy by deactivating 4 of the engines 8 cylinders. The engine will normally operate on 8 cylinders in V8 mode during starting, idling, and medium or heavy throttle conditions. When commanded ON, the engine control module (ECM) will direct the active fuel management system and deactivate cylinders 1 and 7 on the left bank and cylinders 4 and 6 on the right bank, forcing V4 mode. Refer to Lubrication Description and Cylinder Deactivation (Active Fuel Management) System Description."

Thanks. How much is mileage affected if the AFM is shut down?
I would guess this truck has AFM, so with out it on I would imagine you would get 17-18 on hwy. Just a guess. Someone that has deactivated the AFM could probably give a better answer than a guess.

Good grief! I'm sure there are a lot of folks without problems since more often than not the folks without problems never speak up. However, after reading the number of folks having issues with the AFM, it's unlikely I'll even consider the 09.
'11 Silverado with 115K. One set of brakes is all I've done to it other than typical oil changes. Going strong. Hope to keep it for at LEAST three more years.
I have a 2012 with roughly 50k on it, and they must've adjusted the AFM after the initial complaints, because mine RARELY kicks into 4cyl mode.
