I just got another call from GM and the dealership stating that they are STILL waiting for this darn PICO scope to measure the vibration. A quick search on the internet and I did find this article on the GM Techlink site. While I don't think this would address my exact issue, I thought it was interesting. Sorry if this is a duplicate post.

And here is some information about how they do or SHOULD be doing a diagnosis on the vibration issue

well I got a voice mail from my dealer saying that someone from GM came in and drove my truck and there is nothing wrong with it.... Im feeling the tight torque converter which is designed that way so I get better gas mileage.

I have a 14 Silverado crew cab 4x4 and I have a vibration in pedal and floor when I am steady on the gas and it gets really bad when I hammer it on the interstate. Does anybody have a definite fix yet? I can't seem to find one. I also had the shutter at 30 mph when slowing down. I removed clips from rear wheel studs and got rid of it. Now I just need a fix for vibration. I have a 2.5 rough country leveling kit with new blocks in rear but from what I have read this should not be a problem, at least I hope not. I am planning on changing rear blocks back to stock to see if it goes away.

Let' see. "Someone" came and drove your truck. "You" weren't afforded the opportunity to be there. "You" don't know who "Someone" is. "You" do not know what specific expertise "Someone" has; but, since "Someone" was from GM, they must be right, you must be wrong, you cannot discuss the matter with "Someone" but since "Someone" is from GM, the case in closed in GM's favor. Maybe you could have "Someone" from Ford, Dodge, or Toyota drive the truck...wonder what they'd say.

 

You see nothing wrong with this picture?

I just got my truck back from the dealership for this issue. they had it for 6 days and balanced the wheels and replaced the driveshaft. they also tried to charge me for the balance but I refused to pay. they let it go after discussing for a few minutes. I then drove it to work with the same vibration I had 6 days ago. I called them and explained. now they are saying the tires are to blame( flat spotting overnight) . BS I say. so I googled 2014 Silverado vibration and found this thread on this site. didn't read all 248 pages , lol, but I now realize I am not alone. not good. one thing to note on my truck is the vibration is much more intense when the truck is cold eg: parked over night. after 10 minutes on the hwy its pretty much gone. 20" tires btw.

For all you members out there with Shakerado's. Ford has Vibrators too, I decided to make a video today showing the vibration of our new work truck, 2015 Ford F250. If I had a choice to buy a new truck it will be Ram of Toyota from now on.

well that's a new line of BS, at least they are being creative with making up new lies that don't make any sense.

 

with me they said since I drove a regular cab short wheel base truck for 37 years straight, obviously I just don't understand how short wheel base trucks feel and that that's just the way trucks ride lol.

This is the e-mail I received from today from GM....

 

 

I also received an update from the District Manager over the dealership. He
stated that he was the driver of your vehicle yesterday, and he provided the
following information:

"I drove this truck today for vibration complaint. I did not feel any abnormal
vibration. We program the transmission to get the best possible fuel mileage,
and when we do that the torque converter is locked up in the highest gear
possible for that speed. Sometimes this causes the engine to lug (strain to pull
the truck). When that happens, you get vibration out of the driveline. When you
depress the throttle and give the engine more gas, the transmission will down
shift and the vibration goes away. Also with a stiff frame and suspension, along
with the short wheel base, you feel more road imperfections.

I have concluded this vehicle is performing normally and nothing else needs to
be done."

If you feel there is still a concern present with your vehicle, I would suggest
diagnosis by another GM dealer for a second opinion. In regards to a ride-along
with the service technician, that has to be noted and requested when your
appointment is set, as each dealer is independently owned and operated.

CONGRATULATIONS!

 

Waiitng to get the same letter myself. Hopefully soon.

 

How long did it take and did you go BBB or straight to Lemon Law?

You should demand that you be present for another ride along to show the vibration.

yep, just like the times they reportedly fixed mine they kept saying it wasn't vibrating and when I questioned them they admitted they didn't even drive it on a smooth road at 70mph but instead drove it only on rough surfaced city streets at 35-40mph even though the service ticket said the problem was on smooth highways only and when doing 65-70mph.

 

they test drive it in a fashion or certain way to avoid the problem just so they can deny the problem exists.

 

another thing is if they ride with you the extra weight on the seat makes it vibrate less so they can say its minor

    • 2023 GMC 3500 HD, SLE, 6.6L Gas, 4x4, 6 Spd Options:  SLE Convenience Package; Driver Alert Package 1; Spray on Bedliner; X31 Off Road Package; TRAILERING MIRRORS, HEATED POWER -ADJUSTABLE, AUTO DIMMING, WITH TURN INDICATORS WHEELHOUSE LINERS, REAR INC. 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.
