My turn to join this never ending issue. Took my 2014 sierra 1500 cc ltz in for it's 2nd visit today to look at steering wheel vibrations. Problem has been there since new and had rf balancing on tires done at 500 miles, mechanic said it felt fine after. Sorry felt exactly the same, vibration starts at 45 mph and continues to 55mph but only in the steering wheel. Does anyone remember if there was a fix for this type of vibration, sorry not enough time to read through all 212 pages for ideas. Presently at 1900 miles and curious what dealer will try and say this time.

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

If the problem is just in the steering wheel it's probably tire related. Either out of round or balance. Try having them road force balanced with someone who knows how to road force. A good tech who knows road force balancing can get it spot on. 4 years back, I had a shake in my steering wheel, had tires road force balanced and they still had a shake. I brought them to another shop to have them road force balanced and "voila" the shake was gone. This guy was a wiz at road force balancing. He rotated the tires on the rims at a time to get the best balancing on the worse ones. The guy at the first shop didn't do anything like that and probably didn't know what he was doing. It all has to do with the tech and him calibrating the machine, and installing the weights in the correct locations.

 

The road force machine also detects side to side wobbling in addition to vertical vibrations so the tech can know whether the weights should be on the inside, middle, or outside edge of the wheel. Doing this also eliminates the directional pull of the tire, in addition to eliminating vibration. The road force machine puts a roller on the tire with about 1400 pounds of force which is somewhat close to the weight that will actually be on the tire. Road force checks radial and lateral forces and is more accurate than standard balancing. The key is to find a good tech to do it right.

Can you tell me what "final repair attempt" means and who decides it is the final attemt. I,m going through the same crap and actually just filed with the BBB. today 10-06-2014. Would like to know if I or you need to sign on with a lemon law attorney or has GM. been trying not to "LEMON UP' the titles. Some where through these 216 pages I read that they would rather do buy backs BEFORE the title gets trashed. Any advice will be appreciated by me and all in the same " proffessional grade boat".

Signed shakey still shakey Hey! but shakey is the new 'NORMAL OPERATING AS DESIGNED'.

 

I filed a defect notice (lemon law) in July with GM after my truck had been in for 5 repair attempts and had been at the dealer for a total of 27 days. I had multiple sets of new tires installed, a new driveshaft, and "adjustments" made to the rear end. After they received my notice my case was escalated to their mitigation department and they scheduled the final repair attempt. I dropped it off and picked it up two days later - once I got on the highway on the way home it started to shake so I called back to the GM mitigation department and said it still shakes and that I was not satisfied. About a week later they approved a buyback. I drove 5 trucks that all shook worse than mine. GM then offered to order a 15 for me. It just came in last week and I'm waiting for the paperwork to be finalized. I dealt with the shaking truck for 8 weeks while they tried to fix it and have waited another 10 weeks during the buyback process.

 

My recommendation is to remain professional but firm. You need to maintain a good relationship with your dealer and service manager because they are going to be your best advocate.

 

Good luck.

Can any of you post a video from the interior on what the shake/vibration looks like? At highway speeds, 65+, I feel like I'm riding on a sharp bouncy road SOMETIMES but just don't know if it's all in my head and it's due to the sensitivity of the z71 suspension plus the 20" wheels don't help. Seeing a video of what people are experiencing will help me determine if my ride is normal. Thanks!

Do we have build dates on vehicles that are good and bad?

 

All of them, not limited to body, engine, rear end, anything.

I not sold on the tires.. They road forced mine multiple times, indexed, and then finally ended up changing them all out for bridgestone duelers which road forced at 8.. I still have the vibration. The problem has to be further up the drive line in the transmission along with some frame beaming on top of it.

What was the deal they made you?.. Are you sure they "bought it" back or did they give you a "trade assist"? Usually if they buy it back they have to deem the truck a Manufacture buyback on the title and they are trying to avoid that like the plague. And also if they bought it back I think you have the option of taking your money back.

Forgot to mention vibration only occurs when under load or on the gas not when coasting between 45-55 mph

 

 

Check to see if this is happening when your AFM switches to V4 mode.... I noticed this too and was told it had to do with the engine running on 4 cylinders.

The deal was MSRP to MSRP. I haven't seen the final paperwork yet so I'm not sure if it's a buyback or trade assist. I really don't care what they call it as long as I don't have to pay anything to swap out this vibrating truck for a new one. The truck I ordered had the exact same options so the MSRP's are the same. I'll post the details after the deal is finalized.... unless they require me to sign something that keeps me from discussing it. I also don't expect to pay for the 8,500 miles I've put on it either but who knows. The dealer told me that when they do a buy back they usually don't try to get you for the miles.

Yea then if it's just with a load probably drive line related. Pinion angle or trans. Weird how it's just in the steering wheel.

Hi all- I've been watching this post for a while now, since I bought my 50k vibrator a month ago- I've noticed a few things- the causes and few solutions seem to be all over the place; and the service techs seem to be reading the same script. So I think it's safe to say they DO know something is up. However the most recent post about aerodynamics made me speak up- I noticed my bed was about 1/2 off to the right side of the truck, viciously mounted by someone who needs glasses- regardless I actually emailed my service tech and asked him the same question; do you think it may be a aerodynamic issue? I noticed something else as we'll- there are "gaskets" in between the bed and the cab. I am wondering if these May be creating some sort of air compression causing the vibration we are all feeling. That would explain the on and off effect we are all (most of us) experiencing- as the truck turns, whether on the highway or not your air flow over and under the cab changes as the wheels causes turbulence which would allow for a vacuum to be created under and over the truck, relieving the pressure between the bed and the cab- when you straighten out the air pressure begins to resonate again crating a pressure bubble in that small space. I am going to see about taking off the gaskets and see if that makes a difference. In other news I also have the crappy tires and have had 1 replaced- and of course the dealership has NEVER had this complaint before....

Ill,post results soon. Good,luck to all!

Sorry for the typos- autocorrect on iPad and I don't feel like going back- hope you all get the idea!

Until someone removes the bed and drives the truck around this will continue to be speculation. Is your tech willing to remove the bed?

      Your tire pressure issue may just be batteries, you can reset them using tge Ing switch (I think) and the owner's  manual. ChatGTP will b e a faster, better help than Google.

      Towing In Loose Gravel

      The thinking is that starting out in a higher gear makes it easier to avoid applying excessive torque when pressing the gas pedal. In a modern 4wd truck with 4 low and a limited slip or locking rear end, I would use 4 low and try to crawl up the ramp. Sometimes if they are too slippery, you have to back up to let the boat have some bouyancy, and then accelerate briskly to get some momentum to help you pull the through the slippery parts.

      I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.

      Thanks to the convenience of Amazon, I was able to get a few things done to the truck today.  I installed Carquest Premium oil and air filters with five quarts of Mobil1 High Mileage 10-30 along with a quart of Pennzoil Platinum 5w-30 I already had.  The latch for the flip up center console lid was broken so I replaced it along with the power mirror switch.  I found my push retainer assortment this morning and reattached the plastic under the bumper and it was only held on with a few screws and retainers.  Then I programmed a new remote keyless entry fob so I can lock my dog in the truck when I take her out with me (I've got to keep the air going for her since it's been in the 100s).  Finally, I ordered some LED interior bulbs and replaced the reading lamps.  The front lights are working fine while one of the back lights only works intermittently and the other not at all.   While under the truck, I found the source of at least one of the noises: the sway bar links need replacing.  I ordered a set of Suspension Dudes links with Code Red bushings.  Never heard of them, but they're made in the USA and have decent reviews.  While making yet another Amazon order, I went ahead and added a set of front tow hooks.  I went with red, since that's the color of the sway bar link and bushings and it should look decent enough on a black and chrome truck.  Speaking of which, it doesn't bug me much, but the passenger side mirror has a chrome cap while the driver side doesn't, so eventually I'll make them match one way or another.  Oh, and I ordered a $20 TPMS reset tool.  No idea if it will do anything for my sensors but it was cheap and will work for the Ford Transit Connect as well.     For tradition's sake, I ordered a new oil change wrench.  I kept the Snap-On 9/16"x15mm GM wrench I bought when I was 18 in the 2006 GMC from the time I bought that truck until the truck was lost.  While I was tempted, there's no need to spend $80 for a new SO wrench, or even $50 with shipping for a used one on Ebay.  I just bought a Duratech 15mm extra-long ratcheting wrench to do the job as needed.  It works, and if I like that wrench enough, I'll buy the set.

      Multigate electrical problem

      By Another JR · Posted

      The recall is for exactly this issue - those drain holes combined with the limited environmental capability of the tailgate electronics card inside the tailgate were a problem. The “safety issue” was the potential for the tailgate to spontaneously open, but all kinds of tailgate misbehavior can occur from water contamination of that control card.    There is no real fix yet. The initial recall just disabled the tailgate. Later, when parts became available, they would replace bad parts with new parts of the same bad design. My dealer is going nuts because the few times I let them get their hands on my truck, my tailgate is off due to a slide-in camper installation. They really want to cut my tailgate wires, but I won’t give them the chance. I will let them get their dirty hands on it when a real fix (redesign) is available.  My tailgate, which works just fine with sealant plugging the drain holes, will remain safe in a dry storage crate until then.
