Thank you for the extra advise. I am still at the beginning stages and have a couple of weeks to complete my claim. My wife keeps telling me not to pay anyone to try to fix it since I only have 15,000kms on the truck and it's only 1 yr old. All I know is that I will never buy a GM product again after this and the way GM treats it's customers.

Act now! Mileage will hurt above 20k

 

Best of luck.

Well folks, I did it. After all the failed attempts at the Chevy dealer I traded it in for a 2015 Ram 1500 Larame. I have to agree with the other folks on here that have done the same thing, it was th

Apparently you and the other customer reps don't care. If you or GM would care y'all would put more effort in the matter. Just coming on the forum and stating the same repetitive posts and being a 3

Well I have some good news and bad news about my truck vibrations. Good news is that my truck has a significantly less vibration at speed. The bad news is my truck has significantly less vibration. Fo

while I'd never get one because the front end doesn't look good to me, sounds like you got a good truck otherwise. Good luck with the Yohota.

just like with power equipment.... function over form!

My 2016 Denali 6.2L/8sp started the AFM shake (rumble strips) at 30k miles... it's now at the dealer for the 2nd time, they couldn't get it to repeat the condition the first time. The service manager right away said torque converter, then they changed their tune and are blaming the GM Performace center designed Borla exhaust... Borla is awesome, they are sending a new exhaust to prove it's not their product.

 

The dealer says there's a problem and my truck is throwing several codes, but aren't sure what the issue is... I guess the exhaust is them trying to eliminate a cause. Anyone know how this is going to play out? Am I pretty much screwed, and stuck with the shake monster?

 

P.S. Deactivating the the AFM is not an option, I need the fuel efficiency since I drive 50 miles to work..

You need fuel efficiency? That's why you got a full size truck with a 6.2 liter engine? Don't make me laugh. Here is a fuel efficient vehicle for you: 2017 Ford Focus SE, 1.0 liter 3 cylinder turbo, 6 speed manual transmission. They are selling them brand new here in Florida for $12,700 (sticker is about $19,000).

You're a helpful one aren't you? I get 20-23 mpg with this truck and maintaining what I get is important to me. I pull a 19' Ranger, and a 21' Yetti fish house so I need the truck.. Can you tell me the effect disabling the AFM has on MPG's? That would be more useful than your above post.

So, since the Magnuson law ( i dont know spelling​ off hand) where aftermarket parts dont void warranty, they have loopholed and basically refuse to work on the trucks while an aftermarket part is on it. So, youll have to put the stock parts back on. Happened​ to may others in this post. Lift kits, leveling kits, rims, ECT ECT. Ect. As for mpg, i remember reading around 13 mpg unloaded. Ive never done it myself personally. GL.

This is my first post and after seeing the duration and number of pages on this one thread, I'm not hopeful that my issue will ever be resolved.

 

I bought a 2016 GMC Denali 3500HD Crew DRW 4x4 on 3/31/16 (traded in a 2013 black 3500HD Denali Crew Dually 4x4 that never exhibited any vibration). I've had both steering wheel & wheel/tire vibration problems with this truck since I bought it new from Beck and Masten GMC in Houston, TX.

 

The first time it was brought in was on 4/19/16 with 579 miles. I've attempted to let the service department resolve this issue 6 separate times where they have used the Pico, and RFB'd the tires each time. No tires or parts have been replaced to date. The truck now has 17,999 miles and it still has the same issues - extreme vibration of entire vehicle at 60+mph and steering wheel vibration/wobble from 35+mph. The truck is back in the shop currently and the service manager left a voicemail on Friday that they had found one bent inside wheel in the rear. I'm frustrated beyond belief.

 

Without me having to read the 700+ pages in this post, can someone summarize what the causes/fixes have been?

 

Also, how I can contact the regional GM customer service manager or whoever I need to talk with?

I think you'll find that the AFM system doesn't improve mileage much, if any at all. On my '14 I noticed zero difference when deactivating it. Each truck is different, but based on experience from members of this forum, even if it does affect mileage it will be by 1 mpg or less.

when I had my 15 Silverado i saw about a 4-5 MPG loss when deactivating the AFM system when towing it lost anywhere from 4-6 MPG. Now My ecoboost can pull a trailer with equipment and only lose about 1 MPG hahaha and I have no AFM to deal with and no shake :)

How bad is the vibration on a scale of 1-10. The reason I ask is because since I've owned my 2017 Sierra, I've noticed a low humming sound at slow speeds and at times I can see the passenger seat belt vibrating. So I'm wondering, if it's typical road noise, surface conditions, or am I experiencing the same type of vibration issues others are complaining about?

Does that include the unidentifiable Whistle the trucks makes at 60+ and obtrusive road noise too? How about that suicide door seal FERD? Pretty sweet it didn't work for shit with steel I can only imagine nonsense now with AL.......

Nope, I know they all don't just give em awhile! Absolute garbage on the suicide door! I just looked at a FERD 250 with it and the lineup mismatch on those doors was insane! So glad my work dumped FERD Years ago...Couldn't imagine how much trouble the EB's would have given us. Dude, I work with loves the ride on his except for the whistle?

      2015 Sierra Denali L86 cyl 5 misfire at idle

      By Gkistler · Posted

      Hi friends - first time poster. I have a 2015 sierra Denali with 150k miles, I’m the second owner and she’s given me 75k of great service. I run a pulse AFM disable device. Starting Thursday when I exited the freeway after a short local ride it started idling rough, with an obvious misfire shake and was down on low end power.  I got it home and hooked it up to my scannner and found no codes but in live data a pretty bad misfire on cylinder 5. I replaced the coil, plug and wire with all new OE replacements (Delphi gn10165 coil, acdelco wire and 41-168 plug). It’s still behaving the same way after firing the parts cannon at it.   I know cyl 5 is a non AFM cylinder so I am not thinking this is AFM related but I’m kinda at a loss. injector? Bent pushrod? It’s running too well over 1k rpm to suggest those IMO. Has anyone chase this issue before and what was it? Any suggestions?

      Pulsating Noise 4Cyl Mode

      By zibzer2 · Posted

      2017 Silverado L83 5.3l 6speed transmission Hello, not a new member but havent posted in a while and my old signup info isnt working so had to create a new account. anyways, I have an issue with my truck and hope someone can spread some light on whats happening: -when it goes to 4cyl mode it makes a clunk sound (but not when coasting or going downhill) -when in 4 cyl mode and under load it makes a load pulsating sound (not a tick). -goes away completely when in M5 gear or when plugging in an AFM delete. Im guessing it is one of 2 things but im not convinced of either to be honest. 1. lifter stuck in v8 mode 2. torque converter shudder realistically it doesn't seem like the TC as there is no physical vibration , and it never happens in v8 mode. but maybe? and wouldnt a lifter make a sound whether with load or not? any ideas let me know please. thank you!

      Some Assembly is Required

      By Chuck FB · Posted

      Which has made me wonder with the various engine failures of a few brands in the last few years, is it sub par materials such as lifters etc causing failures, or bearing clearances on the crank etc or perhaps bad designing of an engine physically or causing too much load on the components due to the hp/torque they can push out of them. Or is the oil viscosity and additive package of current oils or a lack of oil flow by an oil pump not able to supply sufficient oil at idle or under high load at low rpm. Or is it every item I listed that combined together has pushed the limits so far to the left that there is hardly a margin of safety left and add in some fuel dilution and too long of an OCI and premature engine failure is the result ?.

      By Grumpy Bear · Posted

      He is not saying that an SAE *W20 will have more viscosity than a *W40 due to MORE VII polymers. He is saying that although multiple *W40 may post in the PDS the same or similar 100 C and 150 C viscosities that the blenders choice of modifier TYPE and AMOUNT to get his chosen base to grade will not give identical real world viscosities in shear and at temperature. All will pass the SII test but not all will pass the 100 C HTHS (unpublished value) testing the blender does and relies on to get the required by law "percentage improvement' referenced to his last great work.    Tis the problem with the lie. Once told others are required to support it.

      Parking Brake - Automatic Engagement Questions

      By PunchT37 · Posted

      I have a `25, 1500 that auto sets on incline. Never knew that at first. I have the electronic shifter. Just think if it didn`t do that? Unlike a mechanical shift that you can muscle out of park, how would you get this thing out? That would be a problem.   What I found out later is, I don`t have to push the button to release. Just put it in gear.   Setting parameters? Don`t know if it`s possible.
