Took my truck on a 900 mile round trip last week, got up to 100, the only shimmy i noticed was in the arm rest at about 85, i had an empty cup with ice in the cup holder and you could almost heat it rattling. are you guys experiencing worst? is it in the steering wheel? is the whole truck shaking?

If that's all you have then obviously you don't have the shake or vibration that the people in this thread are complaining about. You should be happy.

Edit: I am curious due to your questions. Did you read any of this thread before posting?

Truck has been to the dealer 3 times for shaking on the highway. 2014 Sierra DC 4x4 V6 AT z71 w/20 in rims. 22,000 miles. First trip dealer rebalanced the good years and sent me on my way. Second trip I was told 2 tires had excessive road force ratings. Truck is over a year old so it was either deal with the tires or replace them at my cost. I opted for 4 new michelins RF balanced. Truck still shakes at highway speeds. Third trip brought truck back to dealer and a field engineer was brought out to road test with vibration analyzers. Was told that it is operating as designed and that any shaking I am feeling is the feel of the road and stiffer suspension package. Although they do acknowledge it does shake. It shakes a lot between 65 and 80. This is b.s. I was told by GM district manager and the dealership to come pick up my truck and now it is back in my possession. I was told they would contact me if a solution for the shaking comes about. With this being said it leads me to believe this is a known issue. Since then I have brought my truck to Sullivan tire to make sure that the dealer did balance my tires correctly and they are indeed balanced.Truck only shakes at highway speeds. It doesn't shake under acceleration or any other speeds with the exception of v4 mode slight vibration. This is my update.

The same speech from the district manager here. The numbers from the road test analyzers always "normal" (they defined what is normal) and stiffer suspension due Z71 and 4WD (BS...). Looks like GM had instructed they people this BS speech and avoid the costs to replace drivelines w/o results.

Yeah and pretty much puts us in a horrible position because now if we try going to another dealer, GM is going to refuse to troubleshoot our trucks because via the engineer they are "operating as designed". I've never had a worse customer service experience for something that costs this much money.

Yeah I read the thread every day and there is a varying levels, and since its hard to guage on the internet who is over reacting and who has legit issues i was curious if the shaking in my arm rest was the start of something more

IMHO and besides some trucks with real problems, in general these 2014 trucks are just super sensitive (conceptual problem) to wheels and/or drive shaft out of perfect balance.

 

When you put the low cost Goodyears and aluminum drive shafts that are produced and balanced "one per minute", with this sensitive truck, the result is this vibration. GM produces about thousand trucks per day, this "border line" design just works in product that are really individually assembled. Like high end products/cars, where they can choose and manage just perfect (within minimal specs) parts.

 

I have Nittos Terra now and the trucks is much better. Next step should be balance the drive shaft in a specialized shop. Again, IMHO and besides some trucks with real problems..

Ford produces 800 - 1000 so does Dodge, and Toyota a day and their trucks don't shake, last generation GM trucks did not shake like these do!

I am not about to be force fed this bull**** we all paid good hard earned money for these trucks.

Some of us rely on these trucks for or income and spend a lot of time in them too!

So we are entitled to a response from GM, or acknowledgement that they are aware these trucks have issues and that they have not forgotten what their customers are dealing with!

I have found GM refused to do anything for me, until I got legal advise and help addressing my troubled shaking, shuddering, clunking, bad reception, moving seat, rusting frame truck.

How could they claim so many miles testing without knowledge of these problems?

GM will never openly admit that all these trucks with shakes and vibrations have a design flaw. It would cost them $$$$$$$$$$. They will take the chance that most customers won't complain, or the ones that do will eventually give up when the next model year comes out.

Not trying to defend GM for this problem but they could still be collecting data on the issue and figuring it out. They could not even have an answer right now but I agree they should at least come out and say they are working on it. Could be like the LB7 duramax injector problem, it took them over a year to come out with anything on that. Maybe I just have too much faith in GM to do the right thing.

"OPERATING AS DESIGNED" :bs: GM better get a clue.

My response to "operating as designed" is this: The the window sticker should state that this truck vibrates at HWY speeds "as designed" so people can make an educated decision on whether to purchase or not. This whole flipping deal has cost me $15k plus time and a lot of BS that one shouldn't have to do when buying a vehicle.

 

GM- I would REALLY like to talk to you. I know you are monitoring this post. Reach out to us on a one by one basis. Show us that you care.

Please do not waste your time waiting on a GM representative. Heres how it works. They will see and respond, congratulate you on your new purchase and apologize for your problem. Ask you to PM them your VIN,set you up an appointment with your service dept, and when you show up to your dealer and explain your problem they will be very nice and give you a very nice rental car or loaner. Diagnosis will probably be something like 'COULD NOT DUPLICATE' , and every time following this you'll get treated like someone who claims they saw Bigfoot. Heck this is just the first series of events. Im already past Bigfoot, Nessie, Little Green Men, the G Spot and other Urban Legends. But good luck. :help:

Scott- Have you read these posts? Have you read mine? I'm on my third truck now. I've been through all of what you said and more.

 

I'm simply reaching out to GM with a public gesture.

 

Do I think they will? No. Would I like them to? Yes.

 

Would it be a good PR move on there part? Yes.

 

Done with it. I'm happy with my new "old/last model year" truck.

Just stopped by my local tire shop to discuss some options on my new old truck. We talked about the new GM trucks and what I've been through. He said that ALL GM trucks are having this vibration issue. Some people feel it or some don't. Some don't drive above 65 or so which is where my vib started. He states that GM knows there are issues but again, won't publicly admit.

I wonder if the 2015 1500's will shake and vibrate? I've been checking dealer inventory at the GMC dealerships in my area everyday for the past two weeks and finally this morning a 2015 Sierra Denali 1500 is showing as "In Transit." The Denali is out of my price range but hopefully it's a sign that the 2015's are starting to roll out. Has anyone driven a 2015 1500 crew cab yet?

    • I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that. 
    • Monday looks like a good day for the dealer to test an ac issue. Hopefully it all turns out good.
    • Paid $2.72 for E85 today.
    • Welcome back! No, it definitely doesn't pass the sniff test. Even "ceasefire" needs an alternative definition these days.    $5.29 at Kroger today
    • 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?
