Shake or Vibration Issues

Azgmcsierra · December 5, 2015

The point is not the percentage of how many trucks are the ones with the Vibration issue....the fact is that my stupid truck that cost nearly 49k has the problem. So is my money and bothers me a lot, I'm sure the ones sharing that same problem are irritated with that comment of yours saying "that's not a large amount of trucks out there with the vibration issue"

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?

I already have a list started for my lawsuit. ill start another strictly for vins.

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

lmao

It's not a large number of trucks that have the vibration

as far as we know

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

Well I drove 5 different ones and every one of them had it to some extent so we will have to agree to disagree on that statement. THis isn't the only truck forum where this is being discussed. And I can't help but wonder how many have it and don't even know it as they don't drive highway miles.

I believe GM is very well aware of this problem, they just will not acknowledge it. (Within the 800,000 plus hits on this site, there are indeed hits from GM Customer Service.). The canned response appears to be, "it's normal", even though thier marketing and advertising say the Denali rides like a luxury car. In my case, the BBB arbitrator acknowledged the vibration when the GM Engineer would not. I would suggest that until vibration is defined in technical terms, with a specification limit, and it can be shown that limit is exceeded, there will be no case and no fix.

tnchevy · December 5, 2015

There will not be a fix for this problem for those who have it. There is just not enough trucks with vibrations out there for GM to even worry about it. Yeah, your truck may have cost $50k (mine was just $30K) but that doesn't mean squat. The only solution for a fix if tire balancing, new rear end, drive shaft ect. doesn't work is to trade for a different truck from a different company and be done with it.

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

I thought the same thing when I first bought mine ,Unfortunately they all don't do it from the beginning and develope the vibration later . Mine didn't start doing it for a few months,others longer . Mine also started getting worse as time went on .

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]

This is the format I used, I started a place so people could find stats quickly and not loading down the GM-Trucks.com

forum, They Have been very supportive and I sincerely apperciate all of the help they have given all of us that are trying

to get through this vibration ordeal.

Anybody knows the "fixes" that GM is doing? Because there's a few guys and honestly can't get back after 460 pages to find them, but seems like a few owners got something fixed up. I'm just wonder which ones are those.....so far after 3 sets of tires and road force balances, my dealership directed by GM are finally changing. the driveshaft, U-Joints and now they told me the differential gears or bearings will be replaced too. I haven't been able to drive it yet because is at the shop still and the service Manager with a GM Engineer want to drive it around on Monday. So that's my Timeliness and fixes, so far.

Damn, not even four months and you have 15,648 miles already? I don't think they know what the actual problem/cause is yet.

Azgmcsierra · December 6, 2015

Lol, yeap I drive all over in Arizona. My company pays for it, gas, insurance, etc. But sucks the fact that is a brand new truck, you know? And all these issues, but I've been noticing that 2500HD and 3500HD aren't that bad of cases or issues like we do with the 1500 trim. So probably next year, I'll switch it for a 2500 HD Turbo Diesel truck. But first I'll drive test every single truck out there, lol.

LongrangeLauber · December 6, 2015

I got mine back last night, the vibe that is. Just when I was thinking of putting wheels and tires on her it started back up, this time instead of 76 it's now real prominent around 78-79, uggg what to do, what to do...

Hello all,

I've been fighting with this for a year. Tire road force helped dramatically. Dealer went thru 9 new tires before they could get the RF to spec.. I have the rally 22" rims which I consider a misapplication. I'm currently looking for 18" rims.

Recommendation: Check your transmission fluid. I'm convinced my problem is torque converter shutter. My fuild is stained and I get brown, black contamination of the dipstick. TC clutch is not fully engaging at certain speeds and the TC clutch plates are wearing out. Most when cold. Run 60-70 miles and I think the heat makes it run better. Hooked up my snowmobile trailer last week and the shake/vibe was 6X worse. That made me start thinking transmission. My problem 100% load/torque dependent.

Shake/vib/ shutter at 60-75 mph and 30-40mph. At 75mph and above, the TC locks and it runs smooth as glass. When the TC is not locked the TC shutter makes the engine flutter in the mounts resulting in vibe/shake.. Engine shake transmits thru the engine mounts and is whats felt due to the TC shutter.

I have a GM complaint and I'm taking it in next week for my 6-7 dealer visit.

Think about it. GM wanted to beat the comp and advertise the highest MPG 1/2 ton. They programmed the transmission shift points all wrong. Then tried to fix it with an 8 speed transmission. The 8 speed has a TSB for the torque converter problem/fix.

Second thing they did wrong was try to make the truck cool looking.. 20 & 22" wheels!! Never had an issue with the 17" rims and RF balance for years. Low profile tires create RF balance issues. Only long term solution is to have more side wall and smaller diameter rims

Cheaply made low profile tires create RF balance issues. The problem here is that GM wanted that big tire look, but at a cheap price. And that backfired badly. Another problem is that low profile tires do not belong on pickup trucks, unless they are used for show only. Low profile large tires on trucks are not practical, they expose rims to easy damage from potholes, and are downright useless for off-roading. And large diameter low profile tires are difficult to balance properly and usually special adaptors are required, which many tire shops and GM dealerships either do not have or choose not to use. Go to a Mercedes and BMW dealer to see how they balance low profile large wheels.

Unfortunately, pickup trucks have been converted into luxury car substitutes to appeal to those who never intend to use them as trucks. GM has deleted drain plugs on radiators and rear differential, but illuminated vanity mirrors are now standard equipment on LT trim trucks? Just who are these trucks designed for? And this creates a whole new market for grossly overpriced vehicles loaded with cheap shiny gadgets, opulent looking (but cheaply made) interiors, and huge out of round tires mounted on crappy Chinese made rims. What's not to like when you are a truck manufacturer and people are willing to pay close to $60k for a half ton Mexican made pickup?

Well, is the GM problem alone. Why? Because first I'm Mexican, I used to work in a manufacturing plant for FORD parts "Electrical Front Harness" and they're having problems with that a few years ago. Why? Because everything was made according to their "SPECS", so a local Mexican Engineer solved the problems after thousands of complaints. He made the small wires gauges a little bigger to hold more "power" and stopped having those weird burning smells after 5 hrs of driving. So don't blame it on Mexican plants. The Silao Plant in Mexico, is huge, clean and have tops engineers. My brother works for the OAKLEY manufacturer plant and he said 85% of English is required before they even look at your resume, bow he speaks, writes and read 100% after one year. He also said to have an interview with the GM Silao Plant is a nightmare of tests and not everyone can make it. Well I guess the main point here, is a wrong and poor american design and specs to a certain level here; trying to make a "work truck" into a luxury ride. The endeavor was huge and probably GM didn't fitted well some driveline components somewhere and chances are that they know these but unable to fix them because of the costs. But hey Nissan and Honda had the balls to recall hundreds of thousands of cars, to fix their problems 2-3 years ago; right? So GM needs to ask the Asians for some good engineers as "loaners" like the one I'm driving today because they can't figure out what's wrong with their trucks, probably they can fix'em for them.
