Shake or Vibration Issues

[MudMutt]

The problem isn't in the tires,driveshaft,or rear diff. Its in the engine management system.. Go to the display on the dash where it shows when it goes from v4 to v8 and watch the magic happen. The vibrations start when the trans is in to high of a gear and the management system that's supposed to "save fuel" goes to v4 and then the truck acts like a stick shift that's in 5th gear at 20 miles an hour.... My truck is a week old and I don't want it anymore cause of this.. Happens both at high and low speeds... 40k for a truck that's unpleasant to drive... Thanks gm... So there ya go general motors.. I'm not a engineer just a a.s.e. certified mechanic that just solved ur problem.. Sorry if I seem cocky or upset but unless you "gm" either buys back my vehicle or fixes it within the next week then this is the response you will get from me. A dedicated gm owner since I could drive.. But those tundras are looking really good right about now...feel free to contact me gm representative on my cell to help me resolve my issue with my new truck 219-588-5002.. Thanks

You are absolutely correct with your diagnosis .... That's why I run M5 when I am driving 50 mph or less. If I am on the highway cruising at 70-75 mph and v4 kicks in, its works fine. I had a 2012 Ram 5.7 with a 6 speed trans and it did the same exact thing ... Had to keep that in M5 when driving city ... When it went into v4 at 45 mph the whole truck would start to vibrate ... AFM just is not perfected yet IMO.

Ur right I probably won't be contacted but I WILL contact corporate and be a thorn in there side until this is resolved.

All I have to say is look up your states lemon laws. The BBB is your friend in this situation and be polite with them. They are there to help you.

I tried putting it in m6 at 75, keeping it out of v4 mode when I was having the vibration issue, mine still vibrated. The dealer put a vibration analysis device in my truck, and said the frequencies matched tire speed. They installed 4 brand new Michelin tires, vibration gone... Well for 5,000 miles anyway, then it came back. Every time they did something with my tires (rf balance) replaced 2 good years, then installed the Michelin's, the vibration would go away, then come back. I took it upon myself to upgrade, and installed nitto LT305/55/20, Vibration has been gone for over 15,000 miles now. There may be another problem, but for me the tires corrected my ride issues.

Putting it into m6 will make it go into v4 mode.

[seansharley]

I had the cruise set at 75, shifted down to m mode, think it dropped to m4, then went to m5, then m6, the vibration was still present in every gear. Been a while, so jogging my memory a bit. I even dragged my foot on the brake, and gave more gas to put a heavier load on to see if it would change. My experience was tires changed it. What I found strange was sometimes it was more noticeable than others, on the same stretch of highway, that led me to believe it wasn't a mechanical issue, to me a bad drive shaft, or rear diff, or trans, or engine mount, the vib would be consistent all the time

This statement posted by STAYBG is not true for my truck… I have the same vib issues that everyone here has described within this thread. The V4 mode is not the culprit. I have the Range deactivation module, which keeps the truck in V8 mode all the time. The vibration issue in my truck are still there in V8 mode.

 

I have not tried to correct my vib issues yet because I'm afraid that I will just go thru the same run-around with the dealer and GM that everyone else has gone thru… not worth my time right now. But I do have a troubleshooting strategy that someone can try if you have access to the proper tools:

 

1. Run the back tires on a dyno wheel at all speeds. This can help to confirm/eliminate the possibility of small road imperfections that some people have mentioned could be transmitted to the seat, floorboard, and steering wheel.

2. If the issue is still there, then change rims and tires.

3. Disconnect the rear driveshaft, and run only the front tires on the dyno in 4WD mode as mentioned in steps 1 and 2.

4. Now do steps 1, 2, and 3 except this time not on a dyno, but on a lift. This will eliminate vibrations from road imperfections, possible flat spots on the tire, and drive shaft angle.

 

If any of these conditions make the vibration go away, then we know it isn't in the shaft angles, rear end, motor mounts, transmission. This may not solve the problem, but can help to eliminate some proposed culprits.

please do tell more about this range deactivation module... Any change in gas mileage?and codes?good warranty?

RangeTechnology.com

They have an icon at the upper left side of this forum page.

Keeping it in V8 mode has dropped my average gas mileage by only 1/2 mile per gallon… not an issue for me.

Keeps in in V8 mode at all times… which I like.

This module does not leave any footprints in your computer… so it won't affect factory warranty.

I had some problems initially with it causing some false codes to show up… but I believe they have fixed it for 2014-2015 trucks.

So far it has been running fine with no codes… time will tell.

WARNING… do not leave the device plugged in for more than 3-4 days without starting your truck… it will drain your battery.

 

My only issue with the truck is the bad vibrations that no one can fix.

[mafd2]

I have a range module and love it. I didn't notice any mileage difference. A must if you have an aftermarket exhaust as well. Keeps it from having that awful V4 drone. I've left mine in for 4 days and haven't had any battery issues. I haven't heard any codes or issues with the new '14 module.

[robedo]

oh noes! I just bought my 2014 Chevy Silverado LT Z71 2WD on Oct 24.

For new years I drove from Atlanta to Fort Lauder a 1100 mile ride 1 way. It was only during the trip that i noticed my center console vibrating violently enough to startle me as my drink kept splashing around. I had just stopped to grab a combo meal and the lid shook right off my drink. At first I thought it was the road i was on, but realized the truck would vibrate between 77 and 83 miles per hour.
Was on vaca for a week without my laptop and figured I would do a search when I got home. My 1100 mile ride back from Fort Lauderdale the truck did the same thing. I was worried that the vibration would losen my passenger seat or rear view mirror or something else.

So here I am home after a hard days work to look up what I think is bullsht and find this thread with over 3800 posts!! not to mention the other threads in this forum alone discussing the issue.
I just paid over 40,000 dollars for this truck! WTF! OMG! I cant even read this anymore.

More of the same on another forum:

This post caught my attention:

 

"It is not wheel balancing. We have had several of 2014 trucks with vibrations, both Chevy and GMC. One of our technicians found the teeth on the ring gear in the differential were different lengths. Supposedly fixed a few. Mine vibrates like crazy. I can feel it the instant I hit the gas and different speeds as high as 85 mph. I haven't had mine done yet as I don't want to throw parts at it.

There are a lot of trucks with this issue. Not sure if the ring gear is really the issue. If it is, they better do something about it. Either a service campaign, or recall. My double cab was less than 500 units in production at Fort Wayne and the assembly quality has been horse $hit. It should never have left the factory with the issues my truck has. Many of them are because of poor assembly. My truck makes me embarrassed for anyone who works there."

 

Also this:

 

"Problems at assy plants with new vehicles: The tires spin on the wheels AFTER assy and being driven. The lube is still wet and allows the tire to slip...noticed more with the chrome 20" and 22" wheels. Get them balanced again. Drive shaft u-joints not pressed in correctly so you get vibes at certain speeds."

so after all of this - why not a class action lawsuit? I have seen enough ppl with this truck and enough posting to know that this is a defect in the product.

 

With everyone filing with the BBB ( which I haven't done - I haven't even gone to chevy yet as I am just reading this thread, I will most likely try to have my tires balanced and the gears, drive shaft, rear assembly addressed first but.. ) We probably should get a list together of members and reach out to anyone across the internet, forums, youtube, etc.. that has the same issue. Once we have about 100 or 1000 ppl, we stop complaining, meet up over the net somewhere, put together some money, get a high priced lawyer and sue as a group for class action and for a repair to our problem. The worst case scenario the government ( that bailed them out ) catches wind of this and takes up our case as a cause for a recall.

In future I can see this truck vibrating all the parts off. Chairs, Rear view mirrors, handles, etc... Its that bad. We need someone to set up a site and to post a link everywhere on the forum. The site should be ONLY about the vibration problems. The site asks for year model, cab style, gear ratio, 2wd or 4wd, length of cab, miles, at which miles it vibrates, make model of tires, aftermarket accessories so we can get a bead of what is really going on. Then submit it to GM. If they fail to honor the problem like a respectable American company. We all put in, get us one of those hollywood, newyork or washington lawyers to file a class action on a defective problem. Hell we paid mostly +40,000 each for it. They are not going to stick it to me.

First I am going to the dealer just to see if they will fix it with good faith. If they do not....... The entire truck buying market will hear this pain backed up by.... Forum owner. My email information is my private information. If GM tries to contact you about me - deny. I am going to try to resolve this the correct way. Then we will see, but like all of you. I feel that as a man I have been taken advantage of at the tune of 40,000 U.S. dollars. That doesn't sit with me AT ALL and I am not going to let this slide.

if need be we are about to unite and MAKE this problem go away. The longer we wait to bring this to light the easier it will be for GM to deny there is a problem or say it is a know issue with their older models. Not here playa

I was chatting with someone else who also has this issue and a site should hit the net in the next few day's !

[mellis]

are there any GM reps out there reviewing this 266 page thread that can offer any support or words of wisdom?? Something more definitive than just, "Sorry about your problems, please feel free to contact your dealer for assistance."

 

This thread is obviously a substantive concern that GM should be aware about at the top floor in Detroit.

[f8l vnm]

Today will be my first attempt at the shake vibration as I'm starting to really feel it in the floor board.

Still my number 1 complaint is the tune on this thing in low speed driving like 10-15 mph crawl
