Shake or Vibration Issues

[rshad]

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

 

What spec truck do you have? Is it the 8 speed trans? Sounds plausible to me. They have to know, i can't see why they can't pinpoint this problem. Just by what is in this post we all know that balancing the tires is not a permanent fix. The drive shaft is not, the ring and pinion is not, there are not too many more things to try. How long would it take to just start breaking down a truck by changing part after part until it is found? This does not make any sense to me. I think it all comes down the the all mighty dollar. And GM does not want to foot the bill. My truck just started doing the vibration issue last week and I am not going to go through all these non working fixes just to pick my truck up again from the dealer and still have the same problem. Something has to happen. Maybe talking to all the major news networks across the country might get the ball rolling.

We should make letters with our own statements, copies of our service tickets and if it's possible GM letters with whatever their responses are and mass mail them to the principal Natiowide TV Networks, Auto & Truck Magazines, to the GM Corporate office and Online Auto Websites; possibly will be the only way to bring their attention to a final fix. I'm doing it this coming week. That makes more sense to me, if everyone gets together and do that, may work.

So, just for shits and giggles, I look up how many used Double (extended) cab or Crew cab 2014-2015 trucks are on the market on Cars.Com . All major brands.

(I weeded out the Regular cabs, since Uhaul and other Fleet buyers blow through a big load of 1/2 ton Regular cabs every year.)

 

9100 Chevy trucks of various trim levels- either double cab or crew cab (2014-2015)

3700 GMCs either double cab or crew cab (2014-2015)

So that makes 12,800 used Crew or Double cab GM trucks sitting there used because the owner either traded in, lease was done, or whatever......

 

2014-2015 Super cab or Crew cab Ford F150? Approx 8300 used sitting on lots.

 

2014-2015 Same thing in a Ram? Approx. 8700

 

And same flavor in a Toyota? 2000 of them.

It's all about the dollars, and nothing is going to happen until the dealers are PO'ed from losing sales. It has to be dealers and consumers together, now it is dealers and GM together. We need a profesionally made sticker / magnet / wrap that covers the entire tailgate, it should look like this. Everybody with the same sign.

 

BUYER BEWARE

GOOGLE SILVERADO - SIERRA

VIBRATION PROBLEM

BEFORE BUYING

 

As soon as dealers start seeing hundreds or thousands of these,start getting asked about it, and media starts asking about it, things will change. Until then we are all on our own. I pick up my new truck after a buy back next week. I got lucky and had a great dealer, some buyers don't.

[Azgmcsierra]

Lol......I like that one, let me finish my issues and I'll do that.....that will be insane if I'm driving a GMC Sierra and I'm advertising the warning.

If you are picking up a 2016 take it for a good test ride first.

Not all trucks exhibit any signs of vibration immediately. Some start vibrating after several thousand miles. So if you can arrange for a 4k miles test drive, go for it.

I was thinking of torque converter also. I drove 73 mph today to work in M5 with tow mode on. Ride seemed to be less shaky. However, driving in M6 just sucks, anytime engine speed gets below 1500 RPMs it seems to get a whole vehicle resonance - definitely drive train related... AFM vibration seems to be getting worse and am getting a very heavy shudder on low speed transition from V4 to V6. So I am hoping that something finally ****ing breaks sooner or later as my dealer is no help!

And some of them do, the 2016 I test drove was vibrating with less than 20 miles on the odometer as I took it off the lot with 4 miles on it. As soon as I got to 73 MPH it was vibrating. They decided to keep it as a demo and two weeks later the transmission failed. it had less than 500 miles on it.

This is incredible. Looks like GM is trying to find out where the breaking point is.

Old Bill now goes down the highway at any speed he wants knowing that vibrations were just all a bad dream. How is it now in the smooth Tundra lane?

There's no doubt in my mind that GM knows exactly what is causing this, and it must be a very small portion of trucks for them not to rectify the issue.

 

All of that being said, take to twitter. GM Customer Service responded very quickly and they are working with my dealership currently. New RCSB w/ 593 miles on with vibration, shudder, and rear-end whine.

 

Details:

RCSB work truck, 5.3, Tow package, 3.42s

I have a 2015 5.3L V8 crewcab AWD with 7000 miles. I started noticing the vibration/shake around 2000 miles in when driving above 75mph. The vibration was intermittent though it got pretty regular as time went on. I went in for the free oil change few weeks ago. I didn't mention about the vibration issue because I was in a hurry and needed the truck back right away. However the SA said there was a software recall for the 4wd system, something about 4wd engaging at cold start (don't have the work order at the moment). After it was all done, I swear the truck drives smoother and the vibration greatly reduced, if not complete gone. Not sure if it was due to the software recall, or coincidence, or if it'll solve the vibration issue that everyone else is experiencing. Just thought I throw it out there.

Just had my '15 Sierra 4x4 CC in on Friday for the complimentary 6K mile service. They did the 4WD recall at the same time.

No vibrations before or after. I made very sure I did between 75-80 on the smooth freeway both on the way there and back home and did not feel any unusual vibrations. Smooth as glass.

Should have read the known issues on the forum prior to purchasing my 15 Sierra SLT z71 11 miles when purchase (2100 currently) - 3-4 Months of ownership.

Truck is going into the dealership Wed for the vibration issue.

Have also notice radio reception issue.

AND

Whine in the rear end. (didn't think anything of it as it was a new truck)

 

I guess the battle begins...........

 

This is ridiculous.
