I had a 2014 Z71 crew cab 4x4 Silverado 1500 that drove awesome!! No vibrations, transmission great and was happy. My wife has the same in a GMC and is great also. Well with all the rebates going on I decided to trade in for a 2017. Same truck just with different tires and I have the dreaded vibration starting at 72 and ridiculous at 78mph. Going in the shop for road balancing today.

I wouldn't bet on a swift resolution unless it's just tires. If you have Goodyear tires, press them for Michelins. RFB is a band-aid for iffy tires. Can you get your 2014 back?

Well some absolutely great news for my situation.

 

I have been having a shudder (believe torque converter) in V4 with light throttle. A few second shudder then would cycle out for about ten seconds, then repeat the cycle. Always in V4 with light throttle or downhill.

It started about 15,000 miles ago but have never been able to catch it during a test drive at my normal service dealership. It used to be once a week on my normal work route and progressively became about a dozen times each way.

 

The tranny fluid is grey but not burnt. Definitely a concern according to local transmission shop...

 

I decided to go to another dealership, closer to where I work to try and get the issue to replicate. With fingers crossed and anxiety at an all time high, I had the Service Manager get in the passenger seat. We got in the truck and headed down the block... The Silverado did not dissappoint me this time, for damn near a block she dropped into V4 and shuddered like hell. His response, "that is not normal".

 

I have an appointment on Monday for them to try to determine what is in fact wrong. There are no CEL on the dash so this will be plug into a computer and get it to happen.

 

In following some other posts on this and other Chevy forums, I am guessing Torque Converter Clutch.

 

I am also hoping that whatever is broken, when fixed, will eliminate the awful resonance I have in the steering wheel.

I have stayed away from this forum for a few months and this thread grew by a hundred pages and it is still going! So it is safe to say that the problem is not fixed yet?

Nope, not fixed yet, just pretty much being swept under the carpet i bet

I have stepped away for a while also. nice to see all my old buddies are still here, with is wasn't the case though and you all could move on from this. hope all is well with you. Any new news?

I have been out of my vibrator for a year and a half and drop in every now and then to see what's going on with this issue....sad to see it's more of the same old same old.

 

I loved a lot of things about my Denali but between the vibration and a lifter failing in the first 5K miles I walked to another brand. Sad because I really do like the new GMC trucks but may never buy one again with the way most of us have been treated after dropping this much coin on a rig.

 

Good luck guys and I sincerely hope everyone gets out one way or another....I know how frustrating it can be.

 

Peace!

Got all 4 tires road force balanced at my dealer and finally got on the highway today, was only for a couple of minutes, but no vibration all the way up to 80mph. Dealer said both front tires were out of GM spec and needed some weights added. Hopefully it stays smooth and doesn't come back!

Shame on you GM.......!

The people, the government, and your loyal customers gave you a second life, yet these f...ing vibrating trucks are still not solved, this is madening to those that are expected to drive them.

 

Get these trucks fixed! These engineers, and your R&D department should be reviewed for incompetence.

I don't know how GM could allow this truck to be built, while shaking down the street.

 

Your customers you screwed over will be moving on.....people report your shaking to NHTSA and GM CEO

Any improvement after the balance? Stock Tires and Stock Wheels?

 

I just contacted a Lemon Law Lawyer and they stated that they will be taking on my case... They also said I'm the 3rd Silverado with vibration issues TODAY. I know nothing here is new but come on already. I really don't want to go to a different brand but I don't know what to do at this point.

 

Sorry for the delay. Discount Tire was able to warranty the 2 tires that were .33 and .34 out on the RFB. Even after owning them a year and putting about 8000 miles on them. However, during that time they had RFB'd them 3 times, dealer 1 time and both the dealer and Discount Tire had the same 2 tires as being the possible culprit.

 

I'm back to having a normal truck. Well, a very tolerable truck. I can still sense it. Stock 20" rims, Nitto G2 305/50/20 tires.

Will be driving the shaking Silverado to Columbus this weekend , last time shaking like hell going part way down . Coming home could not have been any better , this dam think is like a crazy women ! I go to dinner about 1 time a week and two weeks ago was bad , steering wheel shaking on the way to town and on the way home everything ok . Today I drove a short distance maybe up to 45 and you could tell it was ready to come apart , a truck can not take this punishment something has to give . I checked my motor oil and it is dirty [Synthetic Oil ] and I have about 36 % oil life left and I do not do city driving , most out on the 65 to 70s interstate

Next wed, appointment #2, riding with the shop foreman i was told. It comes and goes was fine for 2-3 after new tire and road balancing, was fine yesterday when my brother drove it, but today everything was shaking so bad, frustrating.

Without reading through hundreds of pages, I have a 2017 sierra. I notice when I apply the breaks to come to a stop a feel a bit if a vibe in my feet. Has this been covered? I don't feel anything when driving yet, fingers crossed. But only when breaking I feel this. No one else notices, but I do, it is very minimal but I still feel something. It's not smooth to me. Feels off.

Miles? Sounds like bad brake pads or warped rotors.

THis was my first thought

I second the above

REAR AXLE - 3.73 RATIO INC. GVWR, 11,350 LBS. (5148 KG) INC. FRONT AND REAR PARK ASSIST, INC. ULTRASONIC     I have been launching my new boat and noticed some things related to the parking brake.. I usually set the parking brake (habit) when on flat ground for typical driving.    When backed down on the launch ramp to launch the boat and I place gear selector into Park, the parking brake activates automatically. My second nature is to set parking brake manually and noticed I was turing the parking brake off.  The parking brake appears to be setting itself automatically.   I looked all over my owner's manual and only found references to being on an incline and manually setting parking brake, or at times parking brake will be auto engaged, but nothing specific to my situation.    When is the parking brake automatically engaged?  Under what specific circumstances?  Can the auto set parameters be changed?     I like the auto set feature.  It would be nice if always engaged when shifted into Park and released when shifted out of Park (like my wifes 2025 RAV4).   Thanks!    
    • www.enginelabs.com/news/what-i-learned-today-bearing-clearances-vs-oil-viscosities/     www.enginelabs.com/news/oil-viscosity-can-the-numbers-be-misleading/ The Big Lie… Coming full circle to the reason Lake discusses the Porsche engines in particular. Based on the 2000 samples in the SPEEDiagnostix database, increasing the oil viscosity in these engines, even those run on the track, showed no significant difference in results.   The smoking gun was in the oil chemistry. That is where the data shows higher instances of more wear. Molybdenum was the key; the higher the amount, the less the wear. Speed postulates that higher viscosity oils have more thickeners to artificially inflate their viscosity numbers. These thickeners lose viscosity under shear, and the result is that not all oils of the same viscosity have the same shear stability.   Having enough viscosity is the most important characteristic, but according to Speed, once that required viscosity level is reached, additive chemistry matters more than additional viscosity. Speed also states, oil pressure problems on the racetrack aren’t a viscosity problem; it’s an oiling system problem. Running a thicker oil is just a band-aid for an underlying oiling system problem.
    • Can it still be Assembled II?   Viscosity on the decline by various means. Heat on the rise making that worse. Engine RPM in the tank. Smaller motors with more boost trying to emulate an electric motor. Full torque, zero rpm. Then we will triple the OCI. Argh.    But wait....there is more. LSPI has pushed a shift from Ca to Mg and as that cost more PLUS the run to lower sulfur compounds the TBN is moving in the wrong direction for the increased OCI's demanded.    That not being enough to placate a demand for a parameter they can't measure the other sulfur bearing compounds are also under attack. That would be zinc and phosphorus sulfonate compounds. To some degree those are being replaced with boron esters and others, i.e. titanium ect. All of which have shorter service lives. And there there is the "Secrete Sauce" marketing for AW adds that 'Can't be detected by UOA's" but trust me because I (the blenders) never ever lie.    Spoiler alert; ALL additives are sacrificial! Smaller amounts of the old blended with less robust versions of the new do not equal longer service lives. So what are the blenders recommending? Wait for it.......   MOVING THE GOAL POSTS! OMG      Let's declare the long standing TAN/TBN crossover irrelevant and tell people that soot is a great 'graphite' based lubricant which can aid tribo films. Wait, what? Let's declare that the standards used for oxidation and nitration were to conservative and can be expanded. Let's tell them that because GDI fuel dilution, although being a VISCOSITY KILLER and an acid generator is actually okay because we have better base oils that limit viscosity failure limits. (Said knowing this is measured in fractions of a centipoise and in bases not commonly used in shelf oils)   Lying from the heart is not just the new normal but we have a public, a very young public, that is so ignorant of the facts and so sure of their "RESEARCH" into AI driven models base in regurgitated  instead of scientific research based unvarnished, peer reviewed FACTS that the incoming guard is loosing their grip on reality and the OEM's are tickled pink while the blends bend the knee.    You have an ever limited set of tools to work with. And sooner or later those will be taken from you as the API and the EPA strangle the last remaining fluids from the system. What you have left is your wits. If you care to use them.    At some point in the very near future it will not longer be possible to do "What is best for the machine", and be replaced with "The best you have access too". You WILL be rewarded with half the life and twice the cost. That isn't that hard to predict.         
    • I trust you saw the other comment where he knew what he was talking about !. Yes, these darned newer vehicles with all their so smart they are stupid technology, goes and drains the battery down. As you might see my other comment, I installed a Noco 5 battery tender under the hood and at this point still have the cord routed so I have to lift the hood and then plug it in but am typically parked in a garage or a shed so its not risking the engine hood in the wind. That way I am assured or hopefully so of not finding I have a battery drawn down and can't even start the truck and that also damages the battery to draw it down too far. 
    • I guess no surprise my guesses were wrong !, at least now I know if I ever happen to see it grayed out in my own truck as to what is going on.    I never happened to catch my truck with it grayed out, it seemed every time I would test to see if there was an update it never found anything and yet more than once I would check to see if there was an update and there was nothing, then a day later or even that same morning I would drive to town and after more than one engine shut down in town as I did my errands it would pop up that there is an update now ready to install and the only place I have a connection to the internet is at home by wifi so its not as if it grabbed the download while driving. I don't trust these new vehicles due to all the crap they can decide to do while sitting for some days not running and run the battery down so most of the time if I know the truck will sit for a few days I plug in the battery tender I have mounted under the hood and so the only time the truck must have downloaded software was when it was sitting in the garage where the signal is awful but I have that tender plugged in and somehow it managed to download it. I honestly detest all this crap, way to easy to leave a person stranded.    Since I don't trust any of it I don't do the install of the already downloaded software until I get home and sometimes have even sat in the truck to watch what its doing as its going through the process to its conclusion as its not like it is set up that it will tell you the next time you fire up the engine that the update that was initialed actually installed or installed properly. Yes I can go into the updates and see the list. After I go through the install where I feel its safe to do so in case it breaks down as a result, I will plug in the battery tender after the fact to recharge as I don't know how much power its taking just to do the install and that can take a while for it to install.
