Contacted BBB last week. Then next day GM calls wanting to know what they could do to help. 1 week later, Gm calls back and nothing they can do "it is at factory specs". Same as before. NO HELP! now I can not get the BBB to call me back to discuss the next step. I have called different times of the day, left messages and still have not received a call back. I guess I will need to contact a Lawyer at this point. Truck is still vibrating at 45-60 and I can not get anyone to look at it or work on it. Shame that I have to fight so hard to get something to work the way it is suppose to. Pay good money for a piece of JUNK.

I am in the same exact situation. I haven't contacted the BBB yet because I was hoping GM or my dealer would step up. The engineer said everything is operating within specs and once he said that basically no one would help any further. The dealership said the can't work on it anymore for this issue because GM wont pay for it and GM said they won't help may with trade assistance at all. I cant even take it to another dealer because it is in the system now for this issue. So basically as long as I own my truck and anything that has to do with vibration I am screwed. The service manager told me I should trade the truck for another brand or a 3/4 ton GM truck because these issues are inherent to the 1500 model. I was at the Ford dealer yesterday and have a deal worked out on a F150 but I just don't like it as much as my Sierra and it will cost me $5,000 to get out of mine and into a new ford. I think GM's solution to the problem is setting a set of specs wide enough to state all the trucks with issue are within spec because they just need to cut their losses somewhere with all the issues they are having right now. If they lose a few customers in the process they are okay with it. I'm not sure if it's worth my time and energy to proceed any further and that's what the are banking on. It really sucks because I love everything else about the truck.

File with BBB. It only takes a few minutes and will show GM you are serious. The link is in my sig. Whaddaya got to lose?

I'm gonna look into filing a class action lawsuit. If anyone is interested in being part of it let me know. I read almost all the pages in this thread and I'm surprised no one has done it yet. It's been 2 month since the dealer has had my vehicle to try to fix the issue.

 

I tried to go to another dealership but they told me since I didn't buy it from them I was sol. GM customer service keeps telling me they are waiting to hear back from their internal resource.

 

I'll be damned if I lose 5k on trading it in because GM doesn't want to address the issue.

 

I've already filed with BBB waiting to hear back.

My dealer has several vibrating trucks, I was the first to put LT tires on, and correct the vibe, they just put a set of LT bridge stones on another truck, and it smoothed it out. Seems that's the fix

I think the "lightweight" p tires give the best gas mileage, but can't handle the weight/speed for some reason.

My new 2014 sierra has a vibration issue that starts around 70 and gets worse the faster i go. The odd thing is it comes and goes and is worse on smooth asphault than on rougher roads. The steering wheel and pedal are fine but the seat vibrates pretty bad. I only have 1200 miles on the truck and havent had a chance to go to the dealer yet.

2014 GMC Sierra 1500 SLT Crew cab short bed 4x4 Z71 5.3L 3.42 axle ratio. (Vibration issue solved)

I purchase my truck a month ago. When I took it for a test drive got up to about 50 mph and it shook really bad, went right back to dealer and they said the tires were flat spotted and should smooth out in about a 100 miles if not they would replace them. So took it back down the road again and it was all ready alittle better. The build date on the truck was 4-14 so it had been sitting on a lot for about 7 months so made since to me. On the way home with the truck the vibration was not to bad almost seemed gone at times.After a few weeks had passed did some testing and on relly smooth road is where the vibration was the worst. My tire psi where all at 34 psi. The vibration was really bad from about 73 to 85. I called the dealer told them the problem and the shop foreman told me give it until 1,000 miles if not gone they would replace the tires. So a few days ago took it back to dealer with 1065 miles on it. They first did a road force test on the right front tire Goodyear wrangler sr-a P275/55R-20 that read 41lbs then the right rear 72lbs. They said forget took them off. I had already told them in advance that if it was the tires I wanted to replace them with a set of Michelin LTX M/S2 so they had already order them for me just incase. I told them I would pay the differance between the goodyears and the Michelin if thats what it took it cost me 107 dollars was glad to do that. My vibration is gone. If you really and try to feel a vibration on a smooth as can get road you might feel alittle if you really really try but as good as it gets to me. I think most of the the vibration issues are tires not to rule out some with drive line issues.In the beginning when it really shook bad on the test drive and it got better knew it was flat spotted tire on mine since it set on a lot for 7 months. Hope everone gets there sierra's and silverado's smoothed out. If GM would just admitted they have a problem with these crappy Badyear tires recall all of them if would solve a lot of problems

New Michelins didnt fix mine. Glad for those of you that did get your truck vibration fixed that way, or fixed in any way.

 

AFA class action lawsuits, I dont know everything about them, but it always seems that when I hear about them being settled, the people who had actual damages are awarded pennies on the dollar, while the law firm representing the class action gets millions. Im not interested in making more lawyers millionaires while Im left feeling shorted.

Exactly what I did on my own as well

Hey everybody, *********************

I've recently resolved my shaking/ vibrating issue and would like to share my story to help out:

 

I have read through most of these pages before going to have my own new 2014 Silverado 1500 LT worked on due to significant shaking/ vibration at ~ 65-80+ mph. I first took it to the dealer and told them what was going on, came back a few days later to pick up. I asked if they fixed it, and they hesitated and said "I don't know, you tell me. It's a lot better." .... not what you want to hear. They say they did a Road Force Balance and found all 4 tires were out of spec. They claim to have put them back into or very close to spec. Anyways, I get out on the road and it's quickly apparent that the shake is MUCH worse. It was now shaking up and down and side to side. While driving down the highway at 70-75, one of the weights comes off the wheel and strikes the inner fender, which believe it or not actually made it ride better.

 

Needless to say, I am very upset. So upset that I'm physically sick. Feel that I have made a huge mistake by getting this vehicle and am now trapped with the payments. Next I do a quick google search and drive to an independent family owned tire shop and tell them about it. They ask what tires are on it and are not at all surprised by the issue. Goodyear Wrangler's are circular pieces of garbage. I get there and meet with them. They disclaim they don't really know what the problem is and don't want to sell us new tires only to have the same problem. So we decide to pull the wheels/ tires off and put it on the balancing machine. The owner invited me to stand with the technician and talk to him as he checked the balance. (not road force balancing, just normal balancing on a Hammerhead Technologies machine) The front left tire goes on the machine with current balancing weights still attached from the dealership. Guess what.... its 3oz off on the outside half of rim and 0.5-0.75oz off on the inside of the rim!!!!!! A total of 3.5oz off. They say the average person can detect 0.5oz and greater, so this thing was WAYYYYY off.

 

Not only that, but they had put weights all around the inside of the rim to counterbalance some of the other weights that are in the wrong spot. Tire guys say the weights are all supposed to be grouped together, otherwise you are just chasing bad weights and furthering the problem. All the tires were balanced poorly. While watching the tires spin on the machine, I could see, on every one of them, that they were not round. I'd say they had about a 1/4" to 3/8" or so of up and down difference/ bounce while spinning ( after fully balanced by tire professional). Technician and owner say that if it was a Michelin that was that much out of round, they would send it back for a new one because they are much better tires.

 

Fast forward balancing is done and I'm driving on same goodyear wrangler. Immediately better and very smooth at 65 and below speeds. Now has very very slight vibration, not a shake, at 75 mph and is quite smooth below that. Turns out it's the friggin' tires after all!!! The remaining vibration is due to the fact that THEY AREN"T EVEN ROUND!!!!!

 

A guy on here called Stex said it over and over again that you need to go somewhere else other than the dealership to get this done. He was completely right (even though he doesn't even have a Silverado lol) I wen't back and confronted the dealership about this. Apparently the guy at the my chevy dealership doing the balancing was just hired on, was a troubled teen, and was apparently using a poorly calibrated machine with no training.... Don't think the dealership is a place to have competent work done, that's for sure.

 

Now I have driven over 1900 miles on them and they have smoothed out a tiny bit more, but a small vibration is still present at 70-80 mph. It is very slight and almost not noticeable anymore. I expect it will disappear when I get new tires (Michelins hopefully). On smooth roads the truck is smooth, on rough roads the truck is rough. The thing is stiff so don't expect a glassy ride all the time. I hope this helps.

    • As a matter of amusement I’ll leave this conversation with this. Do you beat the government average fuel estimate? Statistics are a guide to me. Not a rule. Someone once said I have to have the last word. If true and possible may be. I’ll blame that on working in a family business.
    • That is a fair point, and I agree that trying to log “everything in the truck” would be the wrong direction.   There are a lot of modules and a lot of traffic. If the product became a full-truck datalogger, the amount of data would get huge very quickly, and most owners would never use it.   I think the first useful version would need to be narrow: - powertrain-side event evidence - selected high-value parameters - communication / voltage / reset events - pre/post event window - short report first, raw log only as backup   One distinction I should make is between active OBD/PID polling and passive bus capture. If you are polling PIDs through OBD, then yes: the more parameters you request, the lower the effective sample rate becomes, and you are adding diagnostic traffic to a vehicle that is already busy running itself. With passive CAN capture, the recorder is not asking all the modules for data. It is listening to traffic that is already on the bus. So it does not consume vehicle bus bandwidth in the same way that a scan tool polling hundreds of PIDs would. But your point still applies in a different way.   Even if passive capture does not add bus traffic, the recorder still has limits: - processing rate - storage rate - timestamp accuracy - decoder workload - event filtering - report size - user attention span   So the answer cannot be “log everything and let the user figure it out.” The product would need to store enough raw evidence to be useful, but only decode, graph, and present the important parts around the event.   A practical report should probably show: - what triggered the capture - how much pre/post data was preserved - which selected parameters changed - how those values compared to baseline - whether the same pattern happened before - whether any voltage, reset, bus-off, lost-message, or communication fault occurred - selected graphs around the event - raw data only as supporting evidence   So I agree with you. More data is not automatically better. The real product is the reduction from raw data into a useful event report.
    • That makes sense, and I agree with most of that.   I think the product would need both: 1. a default powertrain template, so it is useful out of the box; 2. user-selected priority parameters, so the owner or shop can choose what they want to see first.   Different users are going to care about different things. One owner may care about oil pressure and voltage. Another may care about misfire trend, AFM/DFM behavior, or U-codes. A shop may want communication events and repeatability first. Your baseline point is probably the most important one. Raw data is not very useful unless the report can show what normal looked like for that vehicle under similar conditions.   The way I would think about it is: - start with a basic known-good baseline - learn normal behavior for that specific vehicle over time - allow the event to be overlaid against baseline - show whether the event was a one-time spike or a repeatable pattern - provide a simple severity level, but with clear limits on what that severity means   For example, early severity could be something like: - Info: event captured, no obvious abnormal pattern - Watch: value moved outside baseline, but not repeated - Warning: repeatable abnormal pattern under similar conditions - Critical: communication loss, voltage drop, bus-off, reset, or severe repeated event   I would not want the first version to say “replace this part.” That would be overclaiming unless there is repair-confirmed data behind it. It would be more honest to say “this pattern deserves inspection.”   On the OBD port question, I think OBD absolutely has a role. OBD is probably the right place for: - DTCs - freeze frame - VIN - calibration information - normal scan-tool parameters - Mode 6 / enhanced diagnostic data if available The reason I am still looking at an ECM-side recorder is that the failure may happen before anyone connects a scan tool. If the owner plugs in a scanner after the event, the pre-event evidence may already be gone unless the ECU happened to save it. So I do not see this as “OBD versus ECM-side.” I see it more like: - ECM-side recorder: always armed, rolling buffer, event evidence - OBD/DLC companion: DTCs, freeze frame, VIN, calibration, normal scan data - phone/cloud: status, notes, upload, report generation, notifications   I agree that phone connection and push notifications would be useful. I just would not want the phone or cloud connection to be required for capture. The recorder should save the event locally even if the phone is not connected. The phone should help with event marking, download, notes, upload, alerts, and report viewing.   For a default GM V8 event report, would this list make sense? - RPM - calculated load / MAP - throttle position - vehicle speed - gear / torque converter state if available - coolant temperature - oil pressure - oil temperature if available - battery voltage - commanded AFM/DFM state if available - actual AFM/DFM state if available - misfire counters / roughness by cylinder if available - fuel trims - relevant U-codes / communication events - bus-off / lost periodic message / module reset / voltage drop events Which of those would you remove, and what would you add?
    • I went to the county a few years back to dispute my property taxes. To do that I hired an appraiser and a lawyer. The County Assessor wished to argue that the homes in my neighborhood the appraiser used were all 'distressed properties" and not representative of the "Market Average".    My response was," Of the 50 homes in our subdivision 43 of them were "distressed properties" under bank foreclosure and as such "Distressed IS the market". Lawyer about choked on his coffee and handed the Assessor the 'receipts'.    I won that case on the evidence provided by the Lawyer and the Appraiser.    We have the same thing going on here. My statements were based on the GOVERNMENTS NATIONAL DATA and yours on local markets in areas of your interest. They are both correct....   Thing is, this divergence was based on NATIONAL and not on LOCAL. I think you even understand that. But like you said, we are both stubborn and hardheaded.    I do not see any advantage to disengagement.  But that said we can step back to compose ourselves. 
    • Trust me I appreciate the comments and concerns. It's what I was looking for to help me evaluate the situation and what I want to do. I have decided to move forward with the BORA hubcentric slip on 3/8" (.375") with the extended lugs nuts. Fedex says they should be here Monday :). Meanwhile, the dealer got the remote start and Patriot spray in bed liner done over the last couple of days. Also, I installed an inline stop/start eliminator today. Starts back up in what whatever mode you shut it off in, so you don't have to hit the button every time you fire up.
