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

I have a shaker, vibration frustration! First I want to say I have always been a Chevy and GMC truck guy. I used to brag to everyone how I buy a new truck and never need to see my dealer again for service. Well my luck ran out. I have purchased new trucks starting in 1990, then 1997, had a 2001 a 2007 And a 2013. Never anything like this. My problem truck is a 2015 built in Oct. of 2104. It is a crew cab Silverado LT. 5.3 engine. I now have just over 3000 miles on it. Been to the dealer 4 times for the vibration issue. So far I have had 10 new tires put on and 6 new wheels put on it. They won't budge that it is a tire and wheel issue. I'm getting really tired of hearing we road force balanced and Pico Scoped everything and it should be fine this time. I have contacted GM customer service and felt like I was talking to a wall. They try to say it is the road I drive on, I call B.S. My 2013 GMC and the loaner truck I have driven way too much doesn't shake and vibrate on that same highway. I guess I will just have to keep taking it back, what a pain! GM really needs to own up to this issue because they are going to ruin their reputation very soon with me. I also had them tell me the last service (4 new tires and 2 new wheels) should take care of 90% of my vibration! What, I didn't just pay 40 k for a truck that can only be 90% fixed!

Should have did a little more research before buying this truck but hopefully Chevy can fix it. Going to drop it off today.

I’ve driven the truck approximately 1000 miles on all types of roads. From 40 to 55 the truck resonates (vibrates), especially when decelerating, and going downhill. The more you drive (warn up the vehicle) the worse the vibration seems to get. I can feel it mostly through the steering wheel but can see the dash and center console vibrating in the truck when it’s really bad. I say resonate because it doesn’t seem to be the tires although I really can’t tell. Never had tires vibrate like this before. When driving highway speeds 60 to 75 the vibration is less noticeable (tolerable) but still happening. Almost seems like the driveshaft is out of balance or a bearing is going bad.

I've read through several reples and different sites has there been any specific cause for this problem or is it different for every truck?

 

 

2014 Chevrolet Silverado Z71, LT Extended Cab, 5.3L, 7k miles

Mine did it exactly between 20 and 30 mph it was like driving on a rumble strip that you could hear and feel . Seemed To be getting worse to and didn't notice it when I bought it . Dealer said it felt like every other truck on there lot and there was nothing they could do basically . Will never own another GM product especially a truck and I've owned many over years . The Silerado was the best looking truck out there but the vibration is unacceptable for me and did nothing but aggravate me every time I drove know matter how hard I tried to ignore it or change my driving habits like breaking late at lights to stay out of the vibration zone 20 to 30 MPH . This thing felt like a tuning fork with wheels lol . Traded it in with less then 6000 miles and took my losses and never looked back . Bought a Ram 1500 and have had for 3 months and 3000 vibration free miles Love this truck and the best decision I ever made .I actually look forward to driving this truck every chance I get .

Rumor has it from what I've read the vibration is from the chassis and suspension being so rigid/stiff so that's why it appears so many different folks have different issues causing vibration .

So now they tell me I need to go back to 20" wheels. When I bought my truck I spent extra money (lots of it) to get GM Accessory 22" wheels and tires. So after 4 trips to the dealer and numerous new wheels and tires. They day I need to go back to 20" wheels. What have they discontinued all 22" GMC wheels for the Shaker trucks? Is there a bulletin on that?? I really feel If I do go to 20" wheels that will only let them know that its not the wheels and tires. The main reason I went to the 22" wheels was I didn't like any of the factory 20" wheels. I look through most (not all) of these posts on this topic and I see nothing about the diameter of the wheels being an issue. WOW! what next.

That's pure BS ....putting 20 s isn't going to fix the issue

My neighbor has same setup on her XL that I do less the wheels. I think there is a difference in ride quality between the 22" and 20" wheels but not something that should ever warrant a service visit/call/complaint.

I have stock 20" shoes on my Denali and it vibrates/buffets/booms. Trip #1 to the dealership had them road force balance the tires. Two were out of spec, corrected and did make for a smoother ride at high speeds, but the boom remains.

  • Single instances of "the boom" at low speeds over bumps [driveways, expansion joints...]; coincides when rear wheels go over the bump; sounds like somebody flicking a 12" subwoofer with their finger; doesn't always happen; slightly more difficult to hear; commonly heard on concrete borders between driveways/lots and roads
  • Repeated instances of "the boom" at speeds of ~65km/h and ~115km/h [~40mph and ~70mph]; not heard at speeds greater than 130km/h [80mph]; this is the "buffeting"; annoying as hell; sounds like driving with rear windows down; sounds like double bass from a heavy metal band using a broken amplifier; 30-70Hz range; not all the time, but most of the time; some road surfaces seem to excite it more than others; can be heard more clearly when ear is facing rear of vehicle; fades in and out; towing doesn't seem to change the behavior; happens with seats up, down or folded.
  • Predominately heard in driver's seat; less so in the passenger seat; difficult to hear boom in 2nd or 3rd row.

My Yukon is a stock 2015i short Denali with the only option being the 2nd row bench. No sunroof. 20" wheels with Continentals. 6.2L/8-speed

I'm anxious to read feedback from OmahaBen who's recent repairs align with "Vibration Analysis, Part 1: Tires" and "Vibration Analysis, Part 2: Driveline"

Hey guys, I just bought a 2015 Sierra Z-71 double cab, and I should have looked at this forum prior to buying it. I get pretty bad vibrations in the seats, center console, floor and pedals at 68mph or above. It's harmonical, so it's bad then it's not bad for like 1500ft, then back to horrible. I've contacted my dealer about having the tires road force balanced, but it doesn't seem like that is fixing the issue. I have the 5.3l with the 6 speed transmission, and it came with the 22" wheels and Bridgestone AT Tires. I haven't marked the tires to see if they're slipping, but something is definitely going on, and it's really discouraging. It doesn't seem like anyone has definitively had the issue fixed from the couple pages of what I've read here, and I have to say, my truck is near un-driveable on the highway at this point, it's so irritating. I noticed that the truck has a lot of rake, and it looks like most of them come like that, also the vibration almost feels like a bad u-joint, but if the u-joint was bad it would be doing it while driving around town and probably making noise as well. Just trying to brain storm, I'm at a loss for what it could be - my Tundra never had issues like this and until it gets fixed I guess I'll kind of be missing that truck.

 

Has anyone had any luck getting it fixed, besides the guy that had his whole rear-end worked a couple pages back?

I shared the two links with my service manager and said bring it by and grab your loaner. We will get you straight.

And they still have not fixed it...

 

Dealing with a 2014 with vibrations and now seeing more 2015's pop up with the same issues - GM keeps pumping them out and screwing their dealerships with trying to clean it up...

 

Dealerships probably feel like the clowns with shovels following horses in a parade

      2012 Sierra 1500 AC issues

      By Fishbones · Posted

      I just started having AC issues with my 2012 Sierra. The symptom is blowing warm air on all vents.  Here is what I have checked so far. Compressor clutch appears to be engaging and cycling  I checked all fuses and relay, no issues. The only thing I have notices is the short line that comes from the firewall is very cold / frosted. This line is approximately 12 inches long. The coldness stops when it hits the first line connector. As far as AC compressor - At first start the clutch engages, runs continually, Short AC line frosts up. After idling for several minutes the AC line thaws out some but is still cool and the compressor clutch starts cycling on and off every 5 seconds.  Any suggestions on what to look at next would be appreciated.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Unless you are using a bypass filer system with a Beta of 1000 at 2 micron the commercial filters we have access to, even the very best of them, are poor at the 5 to 10 micron range the typical UOA test can 'see'. Point is there are some truly awful filters being sold A 45 micron Beta 75 filter is what Dyson used to call a screen door on a submarine. That leaves wear metals disconnected from filtration unless particulates are larger than the test can 'see' and yet captured by the filter...which is its job. If that is true then you have a major issue screaming at you.    The graph isn't mine. It belongs to GM and their study on this area. I looked up those studies and provided those SAE tech paper addresses multiple times. Machinery Lubrication displayed it and confirmed it. So if you have doubts about the study you'll have to take it up with GM Engineering. Just like you would have to take up a difference in opinion about the meaning a word with Webster or the length of on inch with the National Institute of Standards and Technology.      Most manuals have two schedules. "Normal Service" and "Severe Service". On it's face it tells you that oil in severe service is more highly stressed and doesn't "Last as Long". The item to bore in on is LAST...what does that mean?    It's the same question one asks about how long to toast bread. What are the inputs? Bread type? Wattage of the toaster? Distance from the elements? What is your preferred level of done?    So lets paint this with a broader brush. Oil is made up of the base and the additive package. The first is altered by heat and oxygen and later is sacrificial with a finite life subject to inputs toward that end. Resistance and supply.    It is the reason an OEM's OCI's are determined by 1.) the specifications of the recommended lubricant and 2.) risk management toward the bottom line. Those lubricants are also subject to cost effectiveness for the OEM.    There is a tendency for most people to believe that the OEM recommended oil rest on the top shelf and that anything other is lesser than. Truth is there are more oils on higher shelves than those on the lower shelf below the OEM's. They make that choice on COST TO THE OEM. Testing is incidental to the margin.    GM makes MONEY, the car/truck is a TOOL to leverage MONEY. Insert whatever car brand you like. Until you forking over a million plus COST not quality is the driver. Thus it is by DESIGN the recommended OCI's and oils fall well short of 'best practice protections'. Proof isn't hard to find. GM Ecotec I-4 2400 breather system and cold start PCM tuning has killed more motors and resulted in more litigation for those that used the 'recommended' practice than GM could bear. What was their response? SHORTEN THE OCI. TWICE.    I don't know how long to leave oil in an I don't know how the oil will respond to MY circumstances and because I don't and can't blanket statement or anecdotal evidence my way out of it.....I TEST and FIND the right OCI for the oil I CHOOSE. There is no shortcut but there is blind allegiance. I don't blindly trust anything.    People hear the word 'detergent' and believe that in the context of oil it means the same thing as laundry soap... Only in the most rudimentary way. It's the first additive to give up on you and they are putting less and less with each new API standard. Solvency can be used but it cost. Some unique undisclosed chemistries can be used. Valvoline R & P in example. OEM's haven't an interest in anything they see as limiting market participation. Whatever.

      By KARNUT · Posted

      For some unexplained reason my father wanted a salvage yard. As we were getting the family business off the ground one brother ran the salvage yard. We gathered there when rained out working on pipelines in the eighties to pull parts. Perfectly good running vehicles would come to us simply because they wouldn’t pass emissions inspection. We were able to swap parts and sell some of them. I got a clean old nova with a bad engine. I pulled a perfectly good small block out a Camaro. A father and son project with a rebuilt engine. The son couldn’t get the engine running right. The problem was the spark plugs weren’t gapped. The 90s vehicles probably widened the gap of shade tree do it yourself engine repair. My do it yourself hot rod repair stopped at the 70s. After that my trusted mechanic kept them in running shape.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      I have an old dental chair in my shop. Something I got for free and apparently it has more than scrap value? People collect them although mine isn't restored or anything. It's visually interesting (1930's Ritter) which is why I like it. And it IS decently comfortable if you kick back.   When a good buddy of mine saw it he said, let me guess, Atlas. It's a conversation piece? As in, you ask the questions, they do the talking?   Where do you hide the jar of teeth?   I would never.

      Are we talking about the same thing, though? The 7 versus 3 wear metals was from Lakespeed's 3.0-specific oil brand comparison test between AcDelco oil and Mobil ESP. The filter remains a constant so whatever excess particles the AcDelco oil is producing aren't being filtered out.   I'm assuming there's a parallel comparison to be made; IF the filter can filter down those particles, engine life increases, and your graph makes the case that a better filter (lower micron rating) can increase engine life. Introducing fewer particles AND filtering those particles with higher efficiency is the best of all worlds. Good oil, good filter.   Where we may disagree is the "baseline relative engine life". I'm more apt to believe the base engine life value is 200k+ on very average oil and filters, "bulk oil of unknown brand and white-label generic fleet-grade filter, Jiffy Lube"   Going from a 10 micron filter to a 5 micron filter should boost a base 200k to 275k in a vacuum as a single factor alone.   Here's the whatabout: How does regularly changing the oil and filter ahead of recommended schedule influence baseline engine life? Most people aren't going to science the heck out of this stuff or ask about Micron ratings, HTHS, or wear comparison tests at Jiffy Lube. Most of the Jiffy lube techs would say they need to call their tech support line to even try to get an answer.   --   Because we love anecdotes here, when I was fishing for 4.3 parts at a local yard this weekend, ALL of the 4.3 vehicles had well over 200k. I love looking at odometers of junked vehicles. How far did THIS go before landing at the crusher? The ones that still had engines weren't seized. None of them were vehicles I'd consider were Amsoil queens, in fact most of them had some kind of service cling-sticker in the corner of the windshield indicating it probably had very average maintenance services. Even the fresh parts rigs- I'm not sure taking an S/T series to 400k has much value considering the running value of those vehicles was probably somewhere around $1,000. 25+ years is a good run on time alone.   The intake manifold I salvaged had clean and bright pool areas. As expected, I found the fuel lines in the manifold rubbed through, just like mine. I'm guessing the lines on that donor truck started leaking, the truck started running rough, and its owner said that's enough I'm unwilling or can't take it out of service for several days, or spend $1000+ to repair it at a shop, it's simply time for a newer more reliable vehicle (or, more than likely, this is the 2nd, 3rd time this has happened in the truck's lifetime). While I don't count on my Blazer for reliability, the thought of giving it away for parts at certain points during my adventure, and being mentally free from its needs has has crossed my mind. I'd be losing $1500 or so, but I can only make more money; not time.
