Are the crew + 6.5 standard box having issues too?

Yes. Any cab and bed configuration, engine, transmission, gear ratio, trim package, etc. are having issues. Seems to be more prominent in extended and crew cabs though. There have also been reports of a few HD trucks that are having issues as well

yes, from what i have read and two of my friend's have that config with 6.2's both not happy but different vibrations than the rest of us complaining about. others in this thread have said their 6.5 CC have vibrations above 70 so it's again, something cumulative not a singular issue which is why WE ALL BELIEVE IT TO BE AN ENGINEERING/DESIGN FLAW that's why even when it's "fixed" it doesn't completely go away, just changes to intermittent and/or different load/speed noticeable

 

i have said it before i'll say it again... maddening... trucks are so nice, quiet, ride great at under 55mph look great and BAM cannot go on a hwy cruise.. the main reason we bought the truck is to have the full size truck RIDE we have become accustomed too having owned so many.. never this issue.. closest was a set of tires/wheels improperly balanced..

I was hoping the issue would have been fixed with the refresh. A bit gunshy to pull the trigger now.

I was also hoping the issue had been found. My 2014 Sierra has 31000 miles on it. At 25000 they rebuild the rear end put 4 new tires on a replaced the rear shocks. I can hardly notice any vibration but sometimes I swear I can feel it. I would call mine 99% fixed. However I believe there is one more missing piece to this puzzle. I keep checking in to see if it has been found.

 

I would probably not buy another 1500 GM until this issue is found. I will either go 2500 or go with another brand Or thoroughly demo a new truck and make sure there is no shake. All the loaners I were given had it too to a varying degree.

 

Good Luck guys.

Kind of hard considering mine didn't develop till 15k, and I believe that's the highest mileage on here. Mine is not as bad as many others on here, so mine could honestly just be tires. Need new ones anyways, maybe it will fix it. If not, I just spent money on tires on a truck I'm not gonna keep lol

Now that I'm thinking about it, people are having the same issue of varying degrees at different speeds. I wonder if something internal of the motor or trans is out of balance, like let's say the crankshaft possibly? As far as why it may come and go, you got me there lol

My thought was the torque convertor or inside the transmission.

But it could be any rotating part inside the engine or transmission.

If it was the engine or flywheel it would do it in neutral and rev the engine up.

So, 5.3's do it, 6.2's do it, 6 speeds do it, 8 speeds do it, Z71's do it, LT's and SL's do it, different gear ratios do it, steel wheels or alloys do it. What is common to all of these trucks? From the front: Wheel bearings?, cv axles?, brakes?, struts (springs anyway)?, Transfer case(?), drive shaft?, rear axles and bearings?, rear ends?, rear brakes and springs.? are six cylinder guys having the same issues? I am intersted to see what the non road test, wheels off the ground results will be. I know my suspension pics up every crack in the road so, i am willing to bet that anything could be causing this right down to buffeting the underside of the truck and transferring through the cab. but then, i am just guessing

Your 2016 vibrates?

yes, I have the V6 and have it too

mine isn't 2016, but i have seen a few reports of 2016's vibrating

Ok. So are we thinking the same thing here? Not engine, not transmission, but is a rotating component? Which leaves front and rear axles and drive shaft. Could it be amplification of a problem through the stiff suspension? I guess with all of the different vibrations called out, i will stick with the 65-80mph one lol.

 

Also, if it isn't in the steering wheel, can it still be in the front end?

    • Ahh, sorry about that - I got some bad info. Newdude is correct. That's what I get for working 13 hours straight ... on my "vacation", lol.   Should've checked the files I had instead of the internet.   Anyway ... this is GREAT news, since this would've been an absolute friggin nightmare to get working.   I don't think the lack of VVT is causing this - you've got another issue. Wiring, I'm betting.   I'm telling you right now, your computer isn't bad. If it worked before the swap, it's working now. You need to do some more (better) diagnostics and figure out exactly what you're missing. Did you test every wire directly at the MAF? Have 5V reference? Ground? If you're reading ZERO g/s, your Hz isn't much use - it's going to be the wrong value anyway. The MAF is not working, and you need to find out WHY.   I got this off the net, so VERIFY first: Pin A: Black (BLK) wire, Circuit 552, serves as the Sensor Return (Ground).  Pin B: Tan (TAN) wire, Circuit 472, carries the Intake Air Temperature (IAT) signal.  Pin C: Yellow (YEL) wire, Circuit 492, is the primary MAF Sensor Signal output to the PCM. Pin D: Pink (PNK) wire, Circuit 339 or 539, provides Ignition 1 Voltage (Power).  Pin E: Tan/Black wire, Circuit 552 or similar, often associated with the Intake Air Temperature ground or signal return.  Global-A list: https://postimg.cc/KKJnQC85    
    • Correct....the end user can't reach to Realtruck directly like they can if they purchase a Bak, Undercover, etc...  It has to go through a dealer.
    • It is 4wd. shop told me it is the slip yoke. But not sure.
    • No, I did not tune out vvt. From what I read it should still be able to run without it, it'll just lose some torque/power.    I can see how that would make it not run correctly, but why would that cause the faulty MAF readings?   EDIT: I just ran a quick test and checked, and as I expected, the computer sees that the VVT cam phaser solenoid is not present, and throws a code for it, and does not try to change the cam angle at all. Commanded position just remains at zero, 100% of the time. This makes me think that the VVT is most likely not the cause of the problem though if anyone has a different/better explanation, I'm all ears.   UPDATE: I was able to find that my scan tool does indeed support reading the frequency (hz) off of the MAF (I thought it wasn't supported but turns out I just didn't know where to look for it). I noticed that regardless of engine state it always however this Is not what I observed with my multimeter. Like I said before, the MAF seems to put out a normal signal during cranking and then the signal drops to a very erratic reading once the engine is running. It seems from what my scan tool is telling me that the ECM is not recognizing this at all, and just reads 0 Hz 100% of the time. This pushes me towards the the PCM itself is faulty. I I have the PCM out of the 2007 donor vehicle, which I may try to connect and program (it's only ~50 bucks to get the software for a one-time programming)
    • Did you tune out the VVT?  07-09 they did not have VVT.  2010-2013 they did.      If you haven't tuned it, its trying to adjust cam timing.
