As listed on the Maroney sticker '19 RST came with a dealer installed option 22" low profiles separate from the factory steel wheels. First 1K, some rear wheel hop and 62-67 mph vibration, not a shake

Crap shoot.

Good luck.

I would also stay away from rims over 18 inches.

Great truck. 

Mine too after the road force balance. Must be the exhaust damper that roars on start......put a 2-3/4 to 4' extension tip on the tailpipe and it roars louder!

got my truck on Wednesday last week. Driving around town, no vibration issues but whenever going between 60-70 mph on the highway, feels like a speed strip. No sounds or anything but vibrates like a speed strip. Dealer has the truck as of yesterday and they are supposed to be putting new tires on. They think there's a hard spot on the tires. (they already re-balanced and road force balance). Not necessarily the classic shake of the silverado but just posting this in case anyone else has this issue

Had the same problem with mine... After a tire rotate and rebalance didn't work the dealer found what the issue really was.  The driveshaft had a dent!  They replaced the driveshaft at no cost since the damage came from the factory.  Hope you can find your gremlin!

Fingers crossed! I'll bring that up to them when I go for the ride along Wednesday :)

2019 Sierra SLT.  I have the vibration / resonance occurring randomly from the back 1/2 of the truck at about 65mph and 1400 rpm while going up a slight incline in 2WD.  I have the same vibration when I slowly backup up a slight incline (driveway).  The vibration will go away if given less throttle or more.  After looking underneath the truck, I suspect it is one of the two stamped metal heat shields near muffler / fuel tank.  I will be taking it in to dealership soon to demonstrate what I can do to repeat the resonance.  The vibration sound is not related to the truck performance, because this truck rides perfectly otherwise.

mine has smooth as silk....been waiting to do anything because it rides so good, cept for body roll...

 

I did have Toyota that had shake at 60mph and never got remedied.....tried everything even new rear axles, it did have bigger rims and tires so.....

PROBLEM SOLVED - The resonance / vibration sounds comes from two metal shields located between the exhaust pipes and spare tire.  In certain road and speed circumstances, they vibrate (similarly to what a tuning fork does).  GMC has not come up with a solution yet, but will reply back here when a solution is provided.

2019 Denali Ultimate with 22" wheels 600 miles is a shaker. Had in today and they road forced all the tires and it is improved but still shakes. One tire (RR) could not be brought into road force spec.  They wanted me to drive it a few days but I can already tell it is going to be a problem. Hoping they will order me a replacement tire when I call them next week. (fat chance of it magically getting better on its own LOL)

Any info would be helpful .  Bought this new 2020 3.0 liter duramax to replace my tundra vibration at 65-plus .  I do have 18” wheels with falken wild peaks on it but it has had a shake that felt like unbalanced tires even with the stock tires.  I have had to the dealership several times they have visually inspected and don’t see a problem just paid them to road balance with little change.  They put it in some test deal “pico” and that’s where they determined it was balance issue .  I just drove back home 100 miles and nearly same vibration especially while going up slight incline .  Not sure where to look for answers.  They did say they didn’t see any dents or weights missing on driveline .  I’m lost but not super excited about spending that much money for a crappy vibrating ride ..

i have a 2020 silverado , since new and i only have 3800 miles on it now, it has had this intermitting vibration , it happens between 58 and 64 mph, feels like your driving on the rumble strip , mostly does it in 6th gear, looks like i`m not the first one to notice this .

My wifes 18’ Sierra Denali had the shake and rumble at 300 miles when new. I researched the Tech service bulletins and found one regarding Trans fluid. We took back to dealer they did the flush and fill procedure and truck has been great since the flush and re-fill.

Turns out they got a bad batch of trans fluid.. I was skeptical but it actually fixed it.

Don’t wait get it flushed before the trans grenades.

There is a tech service bulletin on this.. get the trans fluid flush / fill procedure done.

      Some Assembly is Required

      By Grumpy Bear · Posted

      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.

      Software Update

      By Chuck FB · Posted

      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.

      Thanks for the reply. All settings were correct and the engine was off, as it was supposed to be. It turned out to be something simple. I took a drive for about an hour. I must have had a low battery without knowing it. The voltage gauge on the display looked ok. At the end of my drive, I shut off the engine and the update prompt came up and it updated normally. It’s ironic because one of the features of the update is a reduction of battery drain.
