I could whip up an online form that could help us paint a picture. A quick online survey where the link could be shared and everyone could see the results. The next question then is, what information would be relevant/useful? What do y'all think of this:

 

  • Model Year [2015 or 2016]
  • Model [silverado or Silverado HD or Sierra or Sierra HD or Tahoe or Yukon or Escalade or Suburban or Yukon XL or Escalade ESV]
  • Pickup Wheelbase [regular or extended or crew]
  • Engine [4.3L or 5.3L or 6.2L or 6.0L or 6.6L]
  • Drivetrain [2wd or 4wd]
  • Wheel Size [18" or 20" or 22" or other]
  • Last 6 characters of VIN [textbox]
  • problem [vibration and/or buffeting and/or booming or none]
  • has reported to GM dealership [yes or no]
  • note [free form text box]

 

 

Good idea.

Guys, have you all read this whole thread? This idea has been discussed and there are even seperate threads on the same subject. The conclusion has already been made that it does not matter if your truck is 2wd, 4wd, regular/ext/crew cab, chevy/gmc, etc. There is no rhyme or reason but all configurations can have the vibration. It is also a very small percentage that have the problem even though others would make it seem like they all do it. Mine has the slight vibe at 72-80 mph but every single person I have talked to over the last year that own one of these trucks say it is smooth as glass on the interstate and the best truck they have owned. That is well over 50 people by now. Tires re-balanced solved alot of my vibe problems but it is still there on the Interstate. I am rarely on the Interstate but if I was I would not keep my truck, I would have traded it in on another brand by now. Since I rarely drive past 55 mph it is not worth the loss for me to trade out of it but it would be a different story if I spent a great deal of my time on the superslab.

You know one thing I noticed the other day when I was sitting at a light and slightly moving forward with my foot still a little on the brake I could feel like a pulse in the truck like the anti-lock braking was hitting back and forth. Do you think that maybe something like this could be happening at higher speeds and making the vibration. I also have the vibration in my 2015 double cab 5.3ltr. Sierra. Just a thought. I even could make it happen in a parking lot. Maybe they could try disabling the anti-lock system and see if it makes a difference.

I have noticed that too, one of the things I find even weirder is that while there is always a slight vibe in the truck, the severity can fluctuate even when driving the same roads

True. I suppose the other benefit would have been that we'd have more concrete counts of those with the issue. Would we get further with GM if we were to report 1,000 unique VINs that vibrated?

They'll all come up as Monday, Friday, or overtime builds [emoji23][emoji23]

This is why I brought up about the brakes, this is something that could effect lots of vehicles of different kinds even brands. Just trying to get more ideas out there. There has to be something wrong and either it is a very tricky problem to pinpoint down or GM and others just don't want the fix out there because it could cost them millions. Their was nothing wrong with my 2013 Sierra that I had it was just at the end of the lease so I decided to go with a 2015 Sierra All Terrain which I really like a lot but after just 600 miles I now have this vibration and it starts at around 45 mph and gets worse at 60mph. I am on the highway a lot where the speed limit is 65 and this will drive you nuts if you spend most of your time at those speeds.

Same here, all highway for me. The steering wheel is where I have it the worst although it may be masking any other vibrations. The tires all road force below 10 pounds. It is so annoying and I am about at my wits end. I have a case open and my request to repurchase has been submitted to GM.

Just purchased a 2015 Silverado CC SB 5.3 LT. Its smooth with no vibrations. I guess I got lucky.

Just a select few with very upset customers, sometimes multiple times on multiple trucks lol

Well truck has been at the dealer for 8 days, no call on update so I called. They have been busy you know! Said the mechanic drove it and only felt road conditions, gonna drive it again later...so they started it on the eighth day after drop off. They have had the truck almost as many days as me since purchase. I know they will call and say its nothing we didn't feel anything. Told them last time cant test it going up and down the highway in the hill country. Will keep shifting up and down and never be in 4 mode at at constant. LAST GM EVER......

Keeps us posted on what they say about the repurchase. That will be my next step. I picked my truck up today after being at the dealer for almost a month. I drove it the other day with the mechanic and it drove great, but I asked them to send out the driveshaft to have it balanced properly (after they used hose clamps to balance it). Took it out on a good 80 mile trip on I-71 where the road had been repaved and the vibration/ center console shake was back as if it was never fixed. That makes 5 repair attempts and over 30 cumulative days out of commission. Three different dealerships and still not fixed.

2015 GMC Sierra SLT 2WD here, Dealer replaced tires 3 times to finally went to a different brand From Goodyear we went to Bridgestone. Stopped the Vibration for almost 4 days with a 90% successful rate. Now the 2nd attempt with almost 12 days there, they're replacing the entire driveshaft, U-Joints and Differential Bearings or Gears, whatever was. So I'm still down with the truck in service for a total of 14 days and counting because of the weekend. I'll push it hars for a truck replacement for sure and hope nothing out of my pocket. Im Not sure for the Arizona Lemon Laws, tho.

    • Hi all,   I just bought a 2021 suburban RST with 88,000 miles on it and everything has been good but I’ve been noticing within the last month or so that there are small electrical things going on and I know what the AGM batteries and all the electric electrical in these big trucks you need to have a constant flow with good voltage   That being said, I bought a new battery thinking that that might have something to do with it but today I went to get in and start it and it said no key found when I had the key right in my pocket   It also proceeded to flash the lights inside and outside for over 30 minutes as I went to disconnect the battery as soon as I touch the negative terminal, I heard the relay reset and everything come back up. I got in the truck and started it no problem.   Anyone else have this happen to them? I’m starting to think it’s the KARR system that the dealer installed short circuit stuff.
    • I don't drive this truck on a regular basis since I have a new company truck with no out of pocket fuel or maintenance cost. Yesterday I got it out to run some errands and got the title message on my DCI. A quick Google search suggested to first clean the Map Sensor. I pulled it out and it was sooty so cleaned it up and reinstalled it. Issue not resolved. My OBDII is a couple years old so didn't see any codes. Today I took it to a friend at AutoZone to get him to check it with his reader. It had the following codes: P20C3 P02BB P221F Stating the most likely solution is to replace diesel emission fluid (DEF) tank assembly.   So, I guess a trip to the dealer is necessary. I read where there was a backorder on these tank assemblies several years ago so hope that has been resolved.
    • Are you using a weight distribution hitch system with your trailer as that alone can change the actual tire pressure requirements needed. It would prove interesting to see what the actual individual axle weights are on your truck when you are hooked up to the trailer. In fact when your hooked to the trailer, typically if anything unless it has a large capacity weight distribution system that is over cranked, often the weight on the front axle will be less when hooked up vs driving empty and certainly if one doesn't have a weight distribution hitch. Really the only times one may get up there with weight on the steer axle is if there was a snow plow mounted on the front or a motorcycle on a rack or with a very large jockey tank full of fuel at the front of the box that transfers a bit of its weight to the front axle.    And of course your tires carry more weight for a given tire pressure due to their size vs a stock sized tire so there is that to take into the equation as well. 
    • Great info here thank you. I just joined, we have a 2014 Silverado truck we bought about 4 years ago with less than 5,000 miles on it. It has approximately 24,000 on it now. It appears to have all the standard issues that people are talking about. Occasional charging problems especially using 110 volt, occasional blinking triangle where nothing will turn on when first starting the truck but it will reset itself if you wait 10 to 15 minutes. Noisy coupler between the flywheel and the generator. Our truck is speed limited to 74 mph, is there any way to change that? The latest issue we have been dealing with is when driving long distance on the highway at full speed the generator does not keep the batteries charged. The meter will go into the yellow/red border Zone for charge status and the yellow triangle will illuminate solid but the generator will not keep the battery charged, not sure why the controller doesn't tell the gas engine to increase RPM to increase generator output it usually stays well below 25 kilowatts even though the battery is discharging and I have to slow down the highway to 45 mph and eventually pull over and let the truck idle to charge the battery so I can continue driving at speed. Has anyone had this issue before or have any idea how to diagnosed it? When via Motors was around it they were very helpful at troubleshooting. This becomes much if the Terrain is hilly and you're towing a small trailer
    • I have the GMC accessory (REV) cover installed by dealer. Ordered with the truck.  They did a very good install job, can't find a single issue. Some water gets in around the tailgate but no where else.  You can see daylight around the tailgate but that's not the covers fault.  Installation is means everything. Guys at my dealer were seasoned pros, not inexperienced here today good tomorrow types, like many dealers employ for these jobs.   I don't mind paying for a professional job.
