Do any of you having this problem have trucks with recent build dates?

My build date is 10/15. Ive only had the truck a week, but I took it on the hwy yesterday to see if I had any vibration. Set the cruise to 70, smooth. Cruise at 75, smooth. 79-80, smooth.

 

I'm sorry for those of you having this problem.

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

Ok! I've been following this thread for a month or a couple of days after purchasing my Sierra. Yes, I have the vibration at 70mph +. I like others are (maybe) loyal to GM and have purchased many products with no issues. This is ridiculous for a 50k vehicle.

 

The truck has been to the dealer once and as others they did a road force balance after I referred to this forum. No dice still vibrates at HW speed. An appointment is scheduled to bring it back for further investigation.

 

I feel the same as most here, I want answers and don't plan on playing the game five or six times to fix the problem. Guess I need to spin up on the lemon laws. The first time the vibration started it was significant enough for me to pull over and inspect the truck, I thought the lug nuts were loose on one of the front tires.

 

Again I can't put into words how disappointed I am. I sold my corvette GS for this vibrating truck.

 

On another note is anyone else not satisfied with the Bose system, the Corvette system was great, not the same in the truck, larger cab maybe?

I find it funny that I too have had a light aluminum trailer with a 600 lb snowmobile on it and it had a horrible vibration. I put a small camper on it that weighs much more and it was just the normal vibration I alway experience. I never had a vibration from the snowmobile trailer in the past with my old truck.

If you do not drive over 40 MPH you will never notice any vibration. Maybe this will be the answer from GM? :bs:

Update:

Looking at my paper work last night, the service manager wrote "no vibration present at this time, let customer go". This even after he road with me, confirmed the vibration, told me they were getting tons of these complaints, and that he was trying to get GM involved.

 

This goes to show how the dealers and auto makers with do what ever possible to avoid spending money or addressing issues. I just spent 13 months fighting an 2012 F150 with the dreaded Ecoboost problem. Truck constantly misfired and shut down on me, sent the official buy back or replacement letter and they got their lawyer involved and had the Field Service Engineer state that nothing was wrong with the truck even though it had been in the shop 9 times at two different dealers and was well documented.

 

The auto industry is one of the most corrupt and scam oriented businesses in America.

I also believe it to be the tires as GM/Goodyears's spec of 26lbs Road force is extremely high, especially on this new suspension. My new tire that was put on was 8lbs and I believe all 4 should be below 10lbs for a smooth ride from the research I have done.

I haven't drove mine enough to be completely sure what it is, but I sometimes feel and hear a high speed vibration or maybe more like a hum. Seems to come and go when its lugging just right. Doesn't matter if its in V4 or V8 mode. As soon as it drops down a gear it stops.Thought maybe the exhaust system vibrating maybe. It's not the tires. I told the dealer to let me know if he hears about any bulletins etc. Not really not bad. I'm going to drive it some more before I do anything.

I'm curious as well. I'm not sure if it is a tire. My truck has a horrible vibration now at anything over 60 mph. I have a 6" lift with 35" tires. Had one tire replaced and balanced several times to no Avail. It feels like something in the front of the truck but I can feel it in the steering wheel and the seat. Hell, I can feel it in the floor sometimes. Going to see if I can get the dealer to swap the pro comp tires for some toyo open country just to eliminate one variable.

Actually, 26 lbs road force variation is quite acceptable for a truck tire. It would be a bit high for a car tire, but it is in the acceptable range for a light truck tire. Not the best of course, but should not cause any serious issues. I have had several tires on my Impala that were in the 15 lbs range and the car rode perfectly smooth once the tires were properly balanced.

 

 

The GSP9700 road force measurement default limits for P-metric tires is 26 lbs and LT tires

is 39 lbs. These default limits should be considered only as specified guidelines. They are based

on recommendations from many OE vehicle and tire manufacturers and are a conservative average.

Limits are used with the GSP9700 as a point of reference so that diagnostic messages guide the

operator in decision making processes.

A lot of shops would rotate the tire on the wheel when it requires that much. Buy some good tires and get a good balance. Then one will know for sure and take away a least one variable in the vibration problem.

Has anyone had their wheel run on the balancer without a tire? Could there be a bad batch of wheels?

Update:

The dealer I purchased the truck from called to check on my service and I explained the continuing issue, my frustration and that I had an appointment to get new Michelin LTX m/s2 later that day out of my own pocket. They had me bring my truck back in and gave me a loaner. On the two hour drive home this loaner truck had the same issue. The best test I had was a 20 miles section of brand new asphalt and a speed limit of 75mph. The entire 20 miles I could feel the vibration at 75 and experienced a very poor ride quality. I have driven much older vehicles down this stretch of road recently and the ride was much much smoother. I will keep everyone posted on what the dealer comes back with.

Loaner truck specs:

2014 Silverado 1500 Crew same as mine

Build Date: 8/13 Mexico same as mine

v6 engine different than mine

rear axle: unknown

20 inch wheels same as mine

275/55 R20 Goodyear Eagle LS2 Tires same as mine

      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...

      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.

      Is it an optical illusion in the pic or is the truck really squatting that much horribly?

      It's Been a Long Time...

      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.
