Used Silverado / Sierr@

[kjnengr]

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

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?

[davisd9]

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.
