2014 Silverado/Sierra Member Opinion Poll

[RyanbabZ71]

I really think people are too damn worried about AFM. I have 42,000 miles on my 2011 now without an issue. No oil loss or anything. In town you keep the trans in M4 or M5 and AFM stays off. On the highway it doesn't activate often at all at the speeds I drive. Time will tell but for now I'm not worried about it, though I do wish CAFE laws would be rewritten to make stuff like AFM which has little real world benefit from the factory not utilized.

 

Agree 100%. No issues with it in our 08 Tahoe. Now the camaro is another story

Yes. You don't have issues. Yet.

But others do. And they are worried.

 

Wait for another 20 000 - 40 000mls. Then you can consider your self lucky to have no probs with the AFM.

Maybe.

I didn't have any problems with AFM when my truck only had 42,000 miles either. Wait until you get 75-80,000 miles and get back to us.

Really easy to say something isn't a problem when it hasn't happened to you.....yet.

It isn't widespread. If it were, there would be tons more bad press. GM sells a few hundred thousand AFM-equipped trucks a year, a fraction of our membership here represents that. And average/non-enthusiast are much less inclined to join a forum to talk about how good their truck runs.

I've only heard of it on this site. Nobody that I know w/ a 5.3/AFM truck has had an issue. One mechanic at the local dealer works on most problems like this, and he also does most of the transmission work. I asked him if he saw this problem much, and his reply was simple... "I've seen a few, but nothing special. Haven't really thought about it...". He hadn't torn into motors for oil consumption any more than he had for other reasons.

[VT_Z71]

I've said it many times before and I'll say it again. I am personally close with about 30 given people with AFM-equipped 5.3l GMT-900s in one form or another. Not only has my 70k mile '07 never had any issues, but no one else I know ever has had an engine actually fail because of it. A few of them (usually Crew Cabs) tick a little worse than others, but many of them have well over 100k (of extremely rough construction and logging usage) and still pull strong. I have another buddy with an early '07 LTZ Tahoe that he uses for sales calls all over the state. Its beat to hell, has surpassed 250k on the original 5.3, tranny and G80, and while it does burn a slight amount of oil between changes, what engine doesnt with that past life?

 

And yes, while I have had my AFM tuned out for the past 50k or so, all of the other examples I speak of could care less about modding their truck anything away from stock. They just keep buying them after years of dependable service.

My 07 Silverado AFM (5.3) completely crapped out about 1000k miles ago. I actually kinda like it this way now, albeit I have had no oil burning issues.....yet! The dealership had told me that the AFM failure was cause by a TPS in the throttle body, ironically my oil pressure sensor crapped the bed at the same time. I love my 07 but I have had nothing but problems, small problems, electrical, window switches, rear sliding window motor etc......time to get a GMC finally. Ive been eyeballing them for a while and the new Sierra looks good to me!

Got a 07 Sierra. No difference. Little small probs. Oil burning, rear sliding window, electrical, park assist, and so on..........

 

Only difference is the look of the trucks.

You are aware that GMCs roll down the exact same assembly lines and are put together by the exact same workers right? I do agree the new Sierra looks great but the whole idea that GMCs are held to some higher standard is a myth.

[tanked_darren]

I own a GMC and I consider all other chevy trucks to be inferior!

 

Professional Grade.

I like both. Wish the Chevy had a painted front end like the GMC but there is still hope with the high country edition.

 

I don't like the chrome door handles and mirror caps. Bad move there IMO.

 

I a have had GMCs and Chevy's through the years and I can tell you there are no differences in the two as far as one being the higher end model.

 

So for all the A holes who think one is superior take a moment to consider yourself a cheap bastard unless you have a Denali, which truly is the high end model. Still same frame though and inferior 4wd system.

Completely aware. I think it has better styling cues and an overall cleaner look. I'm not buying it cause I think it's held to a higher standard I'm buying it because the thought of buying another chevy seems like a coin toss to me if I get a lemon or not. Simple placebo effect but ill still sleep at night!

GM is actually making a concerted effort to position the GMC as the higher quality model this time around.

 

"Silverado’s sibling truck, the GMC Sierra differs more greatly this time around with more options coming standard, redesigned exterior, interior and more refined materials including aluminum and carbon fiber appearances in the interior. The target audience is detail oriented craftsmen. The head lights feature LED lights, grille inlets and more details throughout. The first trucks produced by GM were under the GMC name with Chevrolet to follow years after. The GMC truck line was kept so that non-Chevrolet dealers could offer a full line. Now, the Sierra trucks showcase the higher end refined features that are standard."

They will always be the same truck with a different badge and slightly different body. Only higher end about GMC is the Denali line, for the price they can keep it. Sitting in a Sierra or Silverado is about identical. Only thing changed is the steering wheel logo. The 2014 model seems to be that way also from the pictures.

They are certainly very similar but GM is making the effort to separate them. Also, from what I've read, the Tahoes and Yukons are going to be much more different this time as well with different interiors entirely rather than the old "steering wheel swap" treatment only. Even the trucks will be using different materials, etc.
