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

Agree with you there Ericruiz911.  Sometimes better to take the loss and be happy.  Like you say every day you don't enjoy the truck.  Let us know the outcome.   I've done that with other things in my life. 

For a minute there thought you were referring to my ex-wife, lol!  

I have about 45K miles on my 2015 and have as yet not experienced the dreaded Chevy Shake.  It did however come down with the Terrible Torque Converter Shudder around 30K miles.  Dealer performed TSB and so far no more shudder, fingers crossed.

about tires; I replaced OEM Goodyear Wranglers with Michelin LTX Defenders at about 35K miles.  Have to say truck rides better now.  But, I’ve never been happy with the ride of the truck.  However, it is a 4X4 and is on rear leaf springs.  So, have to take that into consideration.  And, factor in that I’m just getting old and grouchy’er, so I’ve been told, lol.  Being that I don’t have any major complaints other than the choppy ride when crossing tar strips in the road and such I’m going to wait till the 2020 comes out and see how it rides.  I’m of the school of never buy the first year model of anything...

You indeed got lucky! Good luck with the new truck. Let us know if it shakes!!!

Thanks! Trust me, I am not leaving with a truck until I get up to 85 on the highway with no shake. Even the slightest vibration will be a no for me. My biggest problem is finding one I like because I really hate the look of the 2019's but it looks like I may go with an all black LT trail boss but we will see. I need to see how it rides first.

Back in the early days of this forum when the posts were coming hot and heavy some of us were betting there would be a thousand pages made before it would shut down.  I’m kinda doubting it will get there.  Traffic has really dropped off.  I know I’ve moved along to the 2019 forum.  Just drop in here every now and then anymore.  Just saying ?

I will say this...I really think GM has screwed the pooch this time around. I know all the brands have problems(foreign and domestic) And most TRY to make it right, But on this one GM has went out of there way to avoid this problem....lying to dealers and customers, and by forcing dealers to do the same! It seems they really stuck it to there Loyal customers this time. And I strongly believe that they wont be able to wait on the next generation to bail them out

I have had a few people message me regarding the process so I am just going to post it here. GM is offering me to get out of my truck and into a new truck off the lot. So what's the catch? Well, I am having to pay almost $3000 out-of-pocket for 'usage'. The formula for this is (miles / 120,000 * purchase price). FYI, the purchase price is NOT the price after incentives, its the MSRP without them, go figure. So right off the bat, I am out $3000. I am allowed to trade into a truck with the same, or less, MSRP as my truck when I purchased it. If the MSRP of the new truck is more than my old one, I must pay the difference + taxes on the difference. What sucks is that the all LT models are now in the $50k range with basic options so it looks like I would have to put more out-of-pocket if I want to get into a 2019 with similar options. With that said, I have yet to completely accept the offer because I am trying to figure out how I can make this work without screwing me. Also found out that this process will take about another 2 months so I can't even find a truck on the lot and leave a down payment. I will just have to hope there is a truck I like sitting on that lot in 2 months and is within budget. Because of this, I tried to pre-order a truck with my configuration that also stays within budget. The dealership said all I need is GM to agree to letting me wait on a new truck because the new truck would take 10 weeks to deliver. He said GM has done it before, but its not a common request. 

 

With what I know now, I advise you to open a BBB case ASAP with the lowest possible miles as soon as you feel your truck is a lemon and will qualify for days out of service or repair attempts. I would have saved myself a lot of cash because they go off the mileage you entered during the initial BBB case opening and then lock in that mileage once the is settled. Doesn't matter if you add another 10k miles until you get your new truck, you're locked into the mileage entered on the BBB case during initial filing.

 

Hope this helps.

This mirrored my experience exactly. It was balancing all along, and after 7 trips to the dealer and over 40 days in the shop, a Hunter tech got mine right on the first try. My truck is smooth as glass now (2,000 miles and counting). The only thing I feel now is the road on the highway, a slight buzz/tingle in my hands anytime I’m going over 73. The Goodyear SRAs have something to do with that road feel, in my opinion. Mine seem to flatspot overnight in the cold weather here in Michigan and it takes about 10 miles for them to warm up and smooth out. A set of Michelin LTXs should alleviate that when I’m due for new treads, but I’m too cheap to drop $1,000 on tires on a truck with only 6,000 miles. 

 

Either way, in short, mine is WAY better now. I am convinced GM techs have no idea what they’re doing unless something throws a code and tells them exactly what the problem is.

Same here, truck always had a shake around 75ish. Got a little more pronounced after I did a rear flip kit, changed to shorter rear shocks & put on 22's.. Finally after about a year of dealing with it, I decided to take it to my buddy who is a GM tech & has been using the hunter machines since they came out. He road force balanced my cheap Ironman 305/40/r22 tires & I tightened the rear shock bolts up again for good measure. Shake is gone & I dont hate driving my truck anymore.. Buddy said these trucks & the C7 vettes, depending on what suspension setting its on,  are very finicky with rear shocks & needing roadforce balancing.

New member here--Just bought a new 2018 Silverado 1500 W/T model regular cab long bed. Got on the highway to take it home and it immediately started vibrating at about 63 mph and above,felt it in the steering wheel and the center console module. Doesn't always do it at that speed depending on the road surface texture but it does it more than half the time.

   Took it back in for service  with about 200 miles showing on the odometer and they road force balanced the tires and told me to put a couple hundred more miles on it in case the tires needed to round back out from sitting on the dealer's lot,it was manufactured 3/18 and it has General Grabber HTS 255/70/17 tires.

   Service writer said if there's still a problem call them and they will order 3 new tires. I asked him why only 3 new tires instead of 4,doesn"t make sense to make sense to me.

He said that 3 of the tires were near high end of limit but 4th tire wasn't and GM won't let them order it. Also looked like they had one of the "junior" mechanics working on it.

    I've put 250 miles on it since and there's still a problem so I'll have to call them and tell them to order the tires and probably have to argue about getting the 4th one.

I've read the last 20 pages of this thread so I'm not getting my hopes up that new tires will solve the problem. Any suggestions on how to deal with this if the new tires don't do the trick?

    Also noticed that extended or crew cab models seem to be mentioned the most in the pages I've read. Does this problem seem to crop up in the regular cab long beds much ? Other than the vibration problem the truck is pretty much what I've expected for a low end trim model.

 

Thanx,

Ive posted in here before and had the Chevy Shake on my 14 with stock chrome LTZ 20s and stock tires. Went to bilstein shocks no change, went to ko2s and method nv's shake changed but still there. Recently traded that setup for stock 20 All Terrain on Nitto Terra Grapplers and 90% of shake is gone. Cant explain it but truck has never been this smooth at hwy speeds.

I too have been fighting the shake.  When I purchased the truck it immediately went back for the shake and had two tires replaced that wouldn't RFB.  It helped, but there was still a shake that could be felt above 60.  When I took it in last time for it's first service I mentioned the shake again.  They really screwed up and gave me an '18 LT loaner that had Michelin tires (New OEM's that replaced alternate to the Good Year tires) on it that rode smooth as glass.  I called the Service Writer and told him if they couldn't get the shake out of my LTZ truck and make it ride better than the LT loaner, I wanted the wheels and tires off the loaner put on my truck for a week.  They RFB'd my tires again and I was told 'One had thrown a weight (not buying that line of crap) and one was able to be RFB'd from a 14 to a 10', whatever that means. 

 

Whatever was done, helped tremendously.  There isn't a shake now until I push the truck well north of 85MPH.

 

I'd say definitely stay after it and do not take no for an answer.  Keep having them RFB the tires and maybe you'll eventually get a Tech that knows how to properly use the machine.

I actually thought about filling the frame with Great Stuff  haha..   maybe that would dampen things. 

Anyone with vibration issues have problems with the forward shaft (on 4 wheel drive versions)?

      AFM Experience

      By Atlas · Posted

      When I had a Bumper subscription for a few days when I needed to run title histories on cars I was looking at, I decided to look up a few of my old/past vehicles.   My 2015 Silverado was still actively registered and it last sold in 2024 with 160k on the clock. No idea if that's on the original engine but someone's keeping it on the road or the original AFM stuff is still going.   It used 0w20. I remember feeding it Mobil 0w20 AFE for the first 30k of its life on <5k OCI's.     Edit: Just did a nationwide search on Autotrader for 2015-2025 Silverados with 5.3's and sorted by highest mileage first.   357k 352k 292k 291k 290k 277k 271k 268k 266k 259k 256k   High mileage on a modern 5.3 doesn't seem all that uncommon, but that's just searching mostly dealer ads on Autotrader. FB Marketplace has all kinds of high mileage 5.3's going back to 2007

      Bridgestone vs Goodyear tires?

      By Chuck FB · Posted

      I can't say I have ever heard of someone getting that type of mileage out of a set of tires even though they rotated on a regular basis but without a doubt if the front end gets wear and those tires are no longer able to track straight it scrubs them off, and driving style and road surface make a huge difference as well.    However that is not what prompted me to comment as it was the new tire theme of sitting in storage waiting to be used scenario. I am sure some tires can last for quite a while in storage if its not too warm and out of the sunlight but unfortunately some tires the way they their rubber compound is formulated they can age and dry out even in a reasonably decent storage location. My brother ran into this maybe three years ago when he was looking at the tires that were on his dually truck and a combination of wear on the rear ones and noticing that the front tires had some cracks around the sidewall of the tire not far from the bead but he had replaced only the front ones not long ago with 2 of the remaining 6 he had left from the initial two sets of takeoffs he had all bought at the same time .... 10 years ago ! ( the years fly by, a truck that only gets used a bit to haul a camper during the summer and sits in a shed for a large part of the year ). That second set of 6 tires, two he had put on the front prior like I said and they had very little wear but those cracks were now present. So we go into the shed where the other 4 tires had been stored all this time and every one of them had the same cracks in the sidewalls and so in the end it amounted to throwing away 6 brand new but 10 year old takeoff tires into the dump that he got a deal on at a tire shop because they aged out. They were a Ford factory equipment BFG tire and those tires did not age well compared to some tires I've seen far older then that and did not show that type of aging. True, they always say up here anyway that 7 years is sort of a limit for age by rights, we don't have the intense prolonged heat that many of you have down in the states that just cook tires and depends on where the vehicle sits when not in use. GB, another words maybe had you bought a set of tires to store it would have been fine as long as you used them up fast enough but there are no guarantees when it comes to rubber, tires or of that other type stored in some guys wallets 😆

      Open Door Chimes When Key is Out

      By Head South · Posted

      2020 2500 HD...I had some trouble getting the key into the ignition switch but went in fine after applying some extra effort. Since then, the door chimes when open when the key is out of the ignition. Also, when I lock the doors with the switch on the arm rest, the driver door locks but then unlocks. (I can lock everything fine with the fob) The message on the little screen displays the "Engine Hours"...kinda weird.   I'm guessing something happened to the ignition switch and it thinks the key is still in there. I unplugged the batteries for 20 minutes, no change. There are a number of videos on YouTube but nothing I can find that address this specific issue. Ideas appreciated, thank you.
