The two times we've noticed it being worse after getting it back from the dealership were AFTER rotating the tires. It's going in for its final repair attempt with an engineer on the 16th, if we get it back and it's "fixed", my husband is taking it to get the tires rotated to make sure it really is fixed! Haha!

 

 

 

 

 

I finally got a chance to test it out after the re-balance and rotation and I am Happy to report that it is much, much better... It was so bad that it may still have some vibe but it feels like nothing to me now... I am headed on a couple hundred mile trip in a week and should get a better idea of where I am at... I will keep an eye on it and keep you all posted...

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

Keep your service records and get rid of it if you can. Why should we even have to have almost 400 pages of dialogue to convince gm there's a problem. Eventually they'll be sued for this...everyone here has had the same recourse and no resolution. I will get my money back one way or another for having to get rid of my truck. I'm enjoying my toyota but I bought Silverado because that's what I wanted. Good luck.

We're going in for our final repair attempt (after 8 total visits for 4 different issues) with a GM engineer on the 16th. After that we'll let the FL lemon law take over.

Well, could be. If the whole issue is vibration causing a resonant response of the entire frame/body/interior system, then changing the stiffness of something in that system will affect the natural frequency and/or damping. In the case of rubber suspension and cab mounts, both stiffness and damping would be reduced when the rubber gets hot. This would have a big effect on the total system response. Same for tires - hot rubber is softer!

 

You know, I pointed out on the SUV forum that GM has advertised that they have gone to new style "shear type" body mounts. The rubber is secured laterally to reduce horizontal body movement, in an attempt to give these full size trucks a more firm, "sports car" -like ride. I still wonder how much of and effect it is having on all the vibration (and noise for the SUV's) issues we are seeing.

 

Anyone else seeing different characteristics in the hot weather?

We're in FL and it's getting to be in the 90s and the vibration is horrible, although it has been since the beginning!

Are you guys who have gone to the Michelin's for a smoother ride running the Tweel? Seems like the only tire that might actually help ?

Today I was told by a GM District Manager of aftersales that he has "fixed them all" and the vibrations are "within spec" and at least i dont have to use my 2 feet to get around.

 

But yet his only solution is more tires, we are up to 13 tires on this truck so far, I dont think that is the issue, and its obvious hes done trying.

It's really sad the way Chevrolet has handled this issue. One thing I have always praised Chevy on is their quality control; but lately I'd say they are worse than just about any other mfg when it comes to problems and resolutions.

 

How many future Chevrolet customers are they costing themselves with this debacle. After leaving the Ram family to try out a Chevy again, I can say I will never go back. Not only are they well behind the curve when it comes to hp, transmissions, and interior features; they are just pushing crap out of the factory with no regards to the consumer.

 

Mine will be going back in again. I've balanced the tires twice, swapped wheels off another Chevy in my inventory, and balanced the drive shaft. All to no avail. Mine is so bad it actually starts vibrating at around 30 which rules out tires. The other odd thing is it shakes during low speed braking. When pulling up to a stop sign it feels like I'm driving over a cattle guard. When pulling a trailer the vibes increase 10 fold.

 

My service manager thinks it might be a yoke issue as they had similar issues with Chevy trucks about 10 years ago. We are going to throw that at it and after that I will be on the phone with Chevy having a discussion about them "re-acquiring" this wonderful piece of machinery.

So far we haven't gotten a lawyer involved yet, I have his number very handy though! I'll update as soon as we get any info after dropping it off on Thursday. Make sure you send in the defect notice that's in the back of your lemon law book to notify them it will be their final repair attempt if you bring it in again. I also have a few videos from this last month documenting the vibrations if we go the lemon law route those will come in handy. Our service manager and advisor are also very much on our side which also helps a lot.

Alter Ego Trip... That sounds like my truck. I don't notice vibes when braking though. Slip yoke was going to be my next undertaking. Mine seems to have a lot of rotational slop in it. I don't know how much is allowed though. My dealer told me the vibes were normal, so now I'm doing this on my own. Let us know what you find out about your yoke.

I'll keep you updated. I will take it in next week and get that done. The driveshaft on mine was out a balance quite a bit but balancing had zero effect on the vibration. It's also strange that mine is much worse when it's cold, then when it's hot out. That's the toughest thing about chasing this gremlin; it doesn't follow any pattern of consistency.

 

My service writer thought I was blowing things out of proportion till I had him drive it. He was blown away how noticeable and obnoxious it is. The other thing I'm noticing is an audible resonance from the vibration. My tech thought it was coming from the rear cab vents, so he blocked them off, with no change.

 

I really wanted to like Chevrolet, after owning them for years prior to switching over to Ram. My last one was an 07 and it was a great truck. Zero issues or complaints. Seems like those days are gone. I mean come on Chevy; if you are going to build a truck that is miles behind your competitors; at least build one that's reliable.

I think the yukons and subrubans have the same drone noise, if I remember right it was caused by the roof liner.

You're right, but I have yet to hear of the issue on a truck. Strange to say the least.

Well it looks like I'm regretting buying my 2015 Silverado two weeks ago, I just joined this forum today and lucky me, I have all the same issues everyone else does.

 

My other two posts are in the radio reception area. I used to install home theater, and own some of the best speakers in the world, and they are trying to tell me that the radio in the truck has nothing wrong with it... yea right. :banghead:

 

The thing I have noticed with the shaking is that it is on the cylinder deactivation, and it is far more prominent at highway speed than local "around town" driving. has anyone else noticed this or do you all have it all the time? and does it get worse as time goes on? My truck came straight off the show room floor, so I didn't actually drive the one I bought, I have driven and been in so many others with none have been anywhere near as bad as mine has turned out to be.

 

I would have said excessive road force in the tires could have been an issue, but for this many people, thats not going to be it. looks like I may be getting rid of my brand new truck and going back to the blue oval or the shiny animal... very disappointed with this truck, atleast I got a crazy deal and will actually make money trading it in. :crackup:

That's a completely different animal. We've had a couple trucks that have suffered extreme vibrations due to cylinder deactivation. Most of the issues you are reading here aren't from that, mine included.

hey alter ego trip,

nice to hear from a fellow HT nut, I actually have 3 set-ups, Im only 24 so most of my stuff in newer, I just upgraded my two subs and I love them.

 

Sunroom:

Pioneer Elite SC-87

KEF R700 Fronts

KEF R800 dipole surrounds

KEF R600 center

SVS PC-12 Plus subwoofer

 

Basement Family Room;

Anthem MRX 310

Paradigm Prestige 75F Fronts

Paradigm Millenia ADP surrounds

Paradigm Prestige 55 Center

SVS PC-12 Plus subwoofer

 

Outdoor Patio:

Old NAD T773 receiver

(2) Niles RS6SI Pro

Im considering adding 3 OS6.5 SI speakers, an inground sub, and an outdoor screen with a projector to make my outdoor audio system a full HT system

 

of course I ran 14/4 and 14/2 cable and done as much bi-wiring as I can

Sorry about that, I was referred to this thread from a different one. My trucks vibration is mostly on the cylinder deactivation and very noticeable at highway speed. have you heard of any fixes for it in your time here? I otherwise love the truck, except for the radio which I'm going to try to get GM to put something else in if I can get the vibration fixed... which seems unlikely now.

Good luck with that. ;)

 

as for making money trading the truck in, the dealer I bought it from made a mistake in the listing, its a $56,500 with all the options and accessories that they put on it, but they had it listed for $37,500 and they legally had to honor the price so thats what I got it for. They accidentally doubled the incentives in the listing, and left out one that I qualified for, and added about 8500 in options and accessories that they forgot to add to the price.

      not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

      New to Me 2010 SLE (Quirks, Issues)

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.

      It's Been a Long Time...

      By fm2176 · Posted

      My initial introduction was here.  It's hard to believe that I last posted in February 2013, having just deployed to Kyrgyzstan.  Since then, I've retired from the military and the 2006 Sierra SLT Z71 that first brought me to these pages was lost.  I went forward to Afghanistan in March 2013 and did a lot of sitting behind a computer on brigade staff.  Within 18 months of getting back to the States, I was selected for Drill Sergeant duty, after which I moved back to Virginia (my home state and where I served from 2004-2008).  That '06 Sierra did a lot of driving between Louisiana, Georgia, and Virginia, and ended up with nearly 320k miles by 2022.  By then, the registration had been expired for a couple of years, but the pandemic had all but eliminated tickets for such transgressions.  Admittedly too, I usually drove my wife's SUV or son's car the 2-3 times a week I had to report to work.  Teleworking sure was fun while it lasted.   I started my retirement leave four years ago and stored the Sierra at my sister's house.  A big mess was made when her fiancé passed while she was taking care of business out-of-state in late-2024, and his son pretty much mismanaged everything to do with the estate.  Even so, I was assured that my truck was safe... until it wasn't.  I found out that my truck had been scrapped about four months after the son took over everything.  There's nothing I could do; I'm 1000 miles away and it was technically abandoned property since he'd even trespassed my sister from her own house (she had no claim to it as she wasn't married, and the fiancé was the sole owner).     Anyway, today I got my second Sierra.  This is a 2010 SLE 2WB CCSB with a little over 200k miles on it.  It's got the 5.3L I'm familiar with and should handle what I need it for.  Hauling stuff that won't fit in the Transit Connect (yep, I sold out, but that's the wife's vehicle) and towing a few times a year tops.  The price seemed decent, considering how much people sell their trucks for in the Deep South: $4500.  I've seen similar trucks listed for more than double that.  I got it from a coworker who left his tag on until we transfer the title next week (Louisiana requires a notary for transfers), so I've been driving it all day.  The rear speakers don't work, which is one of the things that brought me back to these forums earlier.  I can't say how active I'll be as a poster, but I'll be scouring the archives while I find out every little thing I can about the 2010s and particular nuances/problems with my truck.   It's definitely not a GMC, but I got another Willys Jeep a few months back as well, so I'm almost at the same place I was when I first joined gm-trucks.com.  My old 1960 DJ3A was sold back around 2010 or 2011; my current Jeep is a 1946 CJ2A.  So, I've got a slightly newer GMC and a much older Jeep.  I kind of wish I still had that F-250 I had way back when too.  The Dakota is long gone and was technically my brother's truck, though I had it registered and insured.  The F-250 had to go when my grandmother's house was foreclosed on due to mismanagement around 2012 or so.     Hopefully anyone that made it this far isn't too annoyed.  I tend to be long-winded, but I'll be doing more reading than posting in the coming months.
