Crazy again how we all notice varying vibrations. Mine is worst accelerating uphill between 70-80 where you can feel the entire truck start to vibrate. Other than that I usually just notice the petal vibration.

 

When you guys say you feel it in the steering wheel do you feel it on the wheel itself or more so on the center column part where you'd honk the horn. I can always feel a slight vibration if I place my hand on the center part but not the wheel itself. I've paid attention recently while driving other make vehicles and the center steering wheel vibration seems common or normal but I have not notice a gas petal vibration in other makes.

 

I agree it sure would be nice for GM to get this figured out. I have no idea how hard or easy diagnosing vibrations can be in a modern vehicle but it seems like with today's advancements in technology they'd have done it after 2 years now.

 

Overall I sure do like my truck a lot though. Here's to hoping it tows good this summer.

 

For me it's felt in the wheel where you would hold it.

 

Today I noticed my phone charger, resting in the center arm rest cup holder, tick tick ticking away as the vibes intensified.

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

My 2009 had one between 35 and 45. Ended up being the exhaust system. Doesn't new ones have a special valve or something in the exhaust system. Just saying? I found it. They are calling it a flapper valve? Just food for thought!

My vibration issue is random at 40-44 and 75-77. If it vibrate I let off the gas and reengage and it's gone. Happened randomly

In this case I think your AFM system activation and transmission shifting programming are most likely causing this.

I had the tires rotated and it got worse. It changed so I don't think it's that. Never mention vibration is felt in the chairs and center console

Mine is pretty much on the steering column and steering wheel but its only a little bit but enough to be annoying . What I dislike the most is the Audible sound it's like driving on a rumble strip type sound or how when you have a your windows down on certain cars and you get that pulsating type window noise . I noticed when I roll all my windows down you can't hear it and actually a few times I thought the vib was gone but figured out it was just because my windows were down . Even though you could still barely feel it not having the sound and vib at the same time made it much less noticeable . Or if your on a rough road you don't notice it .

I really like my truck to with the exception of the slight vib and starting to learn to live with it but it's a really shame because they are such nice trucks and Excel in so many other areas.

My 2014 had vibration in gas pedal and steering wheel the vibration in the wheel has gone away at 14000 miles the gas pedal still has some but way better then it was the biggest complaint I have is the shake or vibration I get in my seat and center console.Some times it will come and go sometime it will not stop let off the gas,floor it,switch lanes it won't stop. It seems that when it's not doing it all the time it will start up when going around a turn on the high way go for a lil then settle down start up slowly and get worse then peaks out and goes away and starts all over again it's hard to say but after playing around with it going over the same road 5min later the same speed and it didn't do it I'm begging to think its bad harmonics it changes by gas leave and my truck gets worse with a load in the bed and gets better with weight in the cab I can't even haul my dirtbike with out it shaking my off witch is bs going down the highway when two vibration are insync then fall out of sync that would causes the vibration there are vibration waves that run up and down the frame I think if they could find away to deaden the frame some how it may help but I'm not a engineer I may be all wrong with harmonics but that's why they tell us there is no fix for it Im just trying to get different ideas from others on this issue I have drove 3 2015s 2 of the 3 didn't shake the seat or console but the gas pedal and wheel still have it I would think that would get better as mine did

Id say that the light vibration in the gas pedal/steering wheel is mostly harmonics because if im sitting at a rail road crossing with a train going by I can feel it pulsing in and out and when the trains by the vibration is gone, same thing happens if im driving down the street and a Harley rides next to me. Id say its something to do with mounts not dampening engine/exhaust vibrations or since the gas pedal is right by the driver side exhaust manifold its vibrating the fire wall some how which the steering wheel is mounted to the dash bar and then to the fire wall. Just my thought. Mine will seem to do it going down the street every once in a while in a high gear and the torque converter locked lugging the engine, its all harmonics I think.

My truck (1600) miles has only the pedal vibration at this time... It's a rhythmic vibration/shudder felt at highway speeds during light/moderate acceleration, it can be heard slightly and felt in the gas pedal. I would suspect pinion flange warpage or driveshaft balance. The motor mounts in these trucks have lots of movement and slop in them(secret to its comfy-ness) and driveline angle is affected by this. It's easy for us the chase the symptom of a vibration. No one really resolves it too much and I'm going to have to take this into my own hands... =/

My 14 Silverado1500 will now be going back for a 5th time. I've had 3 sets of tires, numerous balancing, a new rear differential...and nothing has changed. The vibration is still felt around 50mph...but real bad once i hit 70. I'vespoken with GM numerous times at the early response unit. Ive threatened the lemon law last week. They are now sending a field rep out this Thursday to look at my truck.

 

Based on this site ive asked them to replace the dtive shaft but dealership just doesnt want to listen. They are usimg some "high tech" pico scope to measure the vibration...so their relying solely on that...

 

Any other ideas besides the drive shaft or rear differential?

 

They know after this week, they either have to find a fix or buy it back.. or else lemon law papers go out Friday.

  1. Has anyone checked the transfer case? Or front differential while engaged? At highway speeds (smooth road tracking straight) changing from 2 wheel drive into 4 HI, the every so slight and annoying vibration becomes very apparent, and a slight wining noise can be heard.... I will be bringing mine in to check this out.

Yes, our Yukon has more vibration in the steering wheel and seat when the system is in 4 Auto then in 2 WD. That said, there is still some vibration when in 2 WD, so not sure what that means....

I have the exact same steering wheel / center console / gas pedal feels you are having. How the hell did you get GM to call you? I've had 2 RF balancing done (1 I had to pay for as tires are warranties until 7500 miles and I'm at 14000).

      Missing thrust bearing? And oil selection

      By Chuck FB · Posted

      Yes I agree, its what amounts to free advertising to let people know about his UOA testing company, and not that there is anything wrong with that but certainly that is a motivator for putting out videos about the science of oil as well as other topics such as oil and air filtration etc. The interesting part I found with his last video is not only the physics behind the reason for the varying wear due to a diesels working torque range causing more bearing load and that higher viscosity oil is of benefit, it was also that the chemistry behind the GM Dexos 0W-20 and the Mobil Dexos licensed 0W-20 are far enough apart that its showing up with a difference in wear even though the two oils are matched in viscosity and in that comparison viscosity was not having the finger pointed at it.    Thankfully youtube is free ( yet anyway ) for viewers to sift through information and of course comes with the good and the bad ( truth and lies ) and we can choose to turn off/not watch what a person finds is bs or just not interested in the topic.

      No doubt... But, as someone who doesn't pay for his services, but who has provided a few views/clicks on his Youtube platform, the data around the Mobil oil testing I think does have some value including to "freeloaders" like me.   A lot of what he's doing is likely showing the OE's work in their oil selection, something that many of us had kind of assumed was true all along, a good balance of both excellent protection and efficiency.

      Lake Speed is drumming up business for his company just by being in the spot-light so he has a vested interest in stoking the 0W-20 fire.  IMO

      summer road trips in the 2026 2500HD

      I knew when I bought my truck that it had off road hill decent or craw control or whatever they call it and rolled my eyes at that but it gets throw on with other options my truck has, I just never had a heads up if the highway speed regular cruise setting had anything to do with the brakes and that took me by surprise. If you've ever been to the top of Pikes Peak and watched those ahead of you on the way down with their brake lights on constantly, one can guess they are probably not gearing down or not enough anyway if their vehicle will allow and a good reason their is a brake check spot part way down where they use an infra red heat gun to check how hot ones brakes are front and rear.    Your right that once one gets out of the front range by Denver and I've not been on that stretch of 285 between Denver and Fairplay myself but I know its high and Fairplay at 10000 feet, Buena Vista at 8000, it drops a bit from there but then your going back up and over the 11000 pass and Durango is at 6500 . So yes your definitely right that 6500 and a lot higher is the theme of going anywhere out in that direction from Denver but hey, the down hill sections give fantastic fuel mileage !.    I don't even look at the fuel pumps for what premium costs here, since I live on a farm and up to this point get fuel delivered I am rarely in front of a fuel pump and when I am, I am often using card lock bulk fuel stations so it tells me what the price is AFTER I buy the fuel. Looking up on gas buddy and converting to US gallons but in Canadian dollars, regular on average of the prices listed was around 5.95 and premium is around 7.00 . That was one reason I did not go for the 6.2 half ton aside from its lack of carrying/towing if one was going by the rule of using premium fuel and until recently one could only buy regular farm gas if playing the few cents off game for farm dyed fuel for a "farm licensed pickup". But yes I hear you on the fuel price difference and like the diesel theme with it often being more expensive then gas it doesn't have quite the charm to it either as it once did although right now here for some reason the price of diesel has come down more so its now inline with the price of regular gas.

      I agree with this assessment. As you know I’m testing longevity with vehicles for the first time. I have a few vehicles I passed to kids and grandkids. We’re all past 100K miles some approaching 170K. I’m the only one doing 5k oil changes. The rest whatever the minder says. I’m the only one doing frequent transmission service. My odyssey the trip vehicle at 200K will be finished as a trip vehicle. I recently changed to high mileage oil, Valvoline. I can’t get past the fact that all manufacturers want to claim long service life. I just don’t make sense that they would go with low weight oil for mileage. While sacrificing longevity.
