I don't recall hearing that many GMT900's having a vibration issue, and the frames are EXTREMEMLY similar between the two generations.
 
It comes down to defective axles, driveshafts, and torque converters.
It's just the byproduct of a stiff frame and not so well designed dampeners.

There are a multitude of issues that could cause the vibration as you just listed 3 and these stiff frames aren't doing anyone any favors on the vibration front.

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

So you'd rather have a flexible frame, like the one under those UGLY POS Tundras, which is rigid as a wet noodle?

Nope. I'm not saying what I'd rather have. I'm just throwing my theory out there. I'm also saying that GM could have designed better frame mounts/dampeners.

Actually, the Frames are insanely taught since the cross members were hydro formed for even more rigidity to transfer across the frame from back to front etc. vs 900 series.  The MAIN culprit is the SHEAR MOUNTS and LOCATIONS!  Added with a CAB STRUCTURE INSANELY built probably 50%+ stiffer over the 900's series... 

 

GM is fully aware of the situation added with out of tolerance components sourced from suppliers...no names mentioned....Look for major revisions at point of connections from CAB to Frame etc.  and obviously sourcing locally for rear end components has been addressed.  Thanks the new trucks LOOK SWEET from a couple birdies?

You want to call other brands POS...have you read this post? Have you looked around this forum? 

 

I had one of these vibrators...not only that I had a lifter go in it's first 5K miles. Then you throw in the sloppy shifting and clunking driveline that every GM truck has ever had and you have a real winner.

Mine and others have had perfect GM trucks. Get rid of your GM truck if you dislike it so much, and go buy a POS Ford, RAM, Toyota, or other brand. Whatever makes you happy.......

Just don't drive anything other than your perfect GM truck...that way you won't be disappointed in your blind brand loyalty.

 

And that truck was gone long ago thank god. I just drop in every once and awhile to see if there is resolution to this as I know how frustrating it is for the huge number of folks this affects.

You trolls need to find something else to occupy your time. Your opinions are not valued, or warranted.

 

This is the second perfect GM truck I have owned. The first one was (GASP) a GMT900, which according to a lot of idiots was a terrible truck.

You are an entertaining little man and I am far from a troll. Good idea removing the "GFY" you originally had in your post...because that just makes you look like an even weaker man with many insecurities. Who gets that worked up over a truck...that you bought, not built. Have a good day sir.

You say I have blind brand loyality. Far from it. I work on trucks from all manufacturers. These are the best by far. So sad you bought a turd... No, not really.

 

Have a nice life.

Had a 2002 Tahoe. Always having electrical problems and AC issues. Worst part was being stranded in Mississippi because the harness going to the fuel pump burned up. Had to wire it myself. And that incident also messed up my gauge cluster......and more.

2005 Avalanche. Electrical and AC problems. Replaced all electrical components to the AC system. Would not work. Guessing it's a harness issue. Mirrors stopped working. Radio stopped working. Taillight fell out...

2006 Colorado. Great truck until the valve seats came apart.

NOW. 2015 Sierra. Vibration/ resonance that I can't resolve. Radio stopped working.( Going to the dealer for that today) Motor was burning oil so I bought a tuner to turn off the AFM. Turning off the AFM fixed most of the shifting issues I had with the truck, but it's still clunky. Many of the suspension components were not torqued to spec. Shocks were bad at 23k miles...... I could be forgetting something.

I've always gone back to GM because I felt they had the best looking vehicles and usually the best price. But they burnt me 4 times in a row. I'm done.

Seeing fan boys on this forum is hilarious, but mostly just annoying for those of us that regret the poor investment we made.

Sorry to hear about your issues. I know the frustration when you spend that kind of money "on a perfect truck" and it turns into a made in Mexico heaping pile. Best of luck to you in whatever way you chose to resolve your situation.

Both of my trucks were made in Indiana. Seeing all of you whiners and trolls with all of your issues is also hilarous.

Agree! I've had a couple Fords starting with a 1978, had a 1992 Dodge Cumins, but my 2015 2500 HD duramax is the best truck I've owned so

far!  No Vibs on mine.  Mine is a club cab with full length bed, wonder if these vibs are confined to short bed trucks. Don't see many long beds

on the road around here.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      That makes sense, and I think you are describing the real product problem. Capturing data is the easy part. If the owner or technician has to manually dig through five minutes of millisecond-level logs, the product has already failed. The device would be at the ECM harness, not at the OBD port, so I agree that data retrieval and event marking need to be thought through carefully. The way I am thinking about the architecture is: The recorder itself should not depend on a phone, app, Bluetooth, Wi-Fi, or cloud connection to capture the event. It should always keep a local rolling buffer and lock the event locally. A button, phone app, or small cabin device would only act as an event marker. If the driver feels a stumble and presses the button 10–30 seconds later, the pre-buffer has to already contain the useful data. For data retrieval, the practical options would be a sealed service USB lead, Wi-Fi download, or a phone/cabin companion device. I would not expect the owner to remove the ECM-side module or work with raw files directly. The cloud or AI side would be for interpretation, not for capturing the event. The truck may have no connection when the issue happens, so the evidence has to be saved locally first. After that, cloud processing could help decode the data, compare it against baselines, and generate a readable report. For the first version, I would keep the automatic triggers conservative and objective: driver event marker bus-off error passive voltage drop / brownout device reset FIFO or queue overflow a normally periodic message disappearing side-to-side communication mismatch, if the topology supports that For “learning normal,” I agree with your point, but I would not want to overclaim it as automatic root-cause diagnosis at first. A realistic first step would be learned baseline comparison for that specific vehicle and operating condition. For example, a value would only be compared against similar conditions: RPM range load / MAP throttle position gear / vehicle speed coolant and oil temperature battery voltage AFM/DFM state, if decoded and validated Then the report could flag things like: this periodic message disappeared compared with its normal timing this value deviated from this vehicle’s normal range under similar conditions the same abnormal pattern repeated after the same type of event the anomaly occurred together with voltage, oil-pressure, misfire, or communication changes But I would still call that “abnormal pattern detected,” not “replace this part,” unless there is enough validated repair data behind it. So the intended product would not be “here is a huge log.” It would need to be an event package: what triggered the capture how much pre/post data was preserved what changed before and after the event whether the device itself reset, overflowed, or saw a bus error selected graphs around the event raw data only as supporting evidence From your perspective, what would make this kind of report useful instead of just another datalog? For example: What are the top 5 parameters or events you would want highlighted first? Would you trust a learned baseline for that specific vehicle, or would you prefer fixed thresholds? How much false-positive flagging would be acceptable before you stopped looking at the reports? What would a one-page report need to show for an independent shop to take it seriously? For misfire, AFM/DFM, oil pressure, or U-code complaints, what would you want the tool to flag automatically?
