Shake or Vibration Issues

650h1 · January 6, 2016

It's honestly sad GM cant fix this issue. I'll bet it has something to do with the cylinder deactivation. Anyone who had the cylinder deactivation shut off in this thread?

Easy enough to test. Put the trans in M5 mode, this disables AFM.

This has been covered in earlier posts in this thread, it did not help the highway vibes.

Took a ride in my Sierra buyback truck today with the GM engineer with his PICO scope. I will be getting another truck. Working with dealer to order one this time to get the latest greatest tranny, software, etc.

Mine is turned off. Vibration still comes and goes.

Hmm, that's bull shit then. How many people have 20"+ wheels with the issue?

Everyone that has the vibration listen up. My 2014 Sierra was fixed by having the rear end rebuilt. It turned out that there are bad seals in the rear differential so they replaced it and the pinion and a gear. Running smooth now. Background: Steering wheel shook at 40-52 mph especially when coasting to a stop. They tried new tires and road force balancing but that did not work. One GM engineer even told my service manager that they could replace every part on the truck and it would still shake. Don't take that for an answer. Paying 40+K for a vehicle and having that shaking is not acceptable. BTW, mine did not start until 5K miles and got worse until about 15K. Now I hope it is fixed at 19K. Good luck and hope this helps.

Argh. Not looking forward to having to go through the dealer for all of this crap. Mine definitely has the slight shudder/vibration on the steering wheel (a bit felt in general, hand off wheel) at the 52-40 range. Both up and down, but mostly during deceleration and braking in that range.

You have to go back thru all these post. It seems like there is no optional part, model or version that has or does not have the vibration problem. It just seems to be hit and miss. That is why it is so hard to pin point to fix. There have been numerous attempts with changing just about everything even more then once and nothing has been found to be the problem.

I will be pissed if they tell me tires! I have Toyo Open Country All Terrains on and they ride like glass and grip like tape! Tires are not the problem in my opinion!

I bought my 14 a few months ago and added a level and 33s...it shakes at 70ish a bit. I bought it used with a tad more then 30K miles on it.... Drove it 15min with the stocl tires to the suspension shop that did my level/tires.

Can i still take it to the dealer and have them look at it?

I have larger than stock Toyo Open Country AT2's (no level) on my 2014 and I have a petal vibrations at around 70mph+ and a slight "unsettled" feeling sometimes as some on here have called it. Dealer wouldn't look at my truck with the Toyos on it and had to swap em back to stock for them to look at it. They blamed the Toyos. They did re-mount and re-balanced my Toyos for me and sent me on my way. The petal vibe I feel is basically the same since it was new, it's annoying sometimes but has not gotten worse. I have almost 20k miles now. But I had these same Toyo tires on my 2005 and didn't have this issue so its hard for me to believe it's tires unless these truck are much more sensitive to tires. Oh and one of the service write up guys compared my 2014 to my 2005 as being like a 3/4 ton or HD truck because the new ones have stiffer stronger frames and suspension as to haul and tow more. I guess this is what we get when the truck companies continue to play the whos got the biggest d*ck game always trying to one up each other on the largest towing capacity crap. Honestly if I needed a truck to tow 11k lbs I would have bought an HD. They need to cut this crap out with the half tons.

Exactly what I told the engineer today, crew cab short box trucks today are people haulers and they need to start reflecting that. If you need a 3/4 ton buy one.

Tire size doesn't matter. I've been going through this for 2 years now and am on second Silverado, soon to be third if they do not give me a full buy back this second BBB case.

The rear axle fix will correct the 40-50mph vibe in steering wheel, mostly felt during a coast to stop. That is NOT the vibration other people feel at 70-80mph. This problem, GM has no fix for other than replacing tires, removing body and rebalancing, removing engine and remounting, etc.

I test drove 11-12 (lost count) Sierra and Silverado trucks while searching for my MSRP replacement as part of my BBB settlement. It took that many to find one that didn't vibrate. And, after about 1000 miles, it also started vibrating. In my experience they ALL have the problem of 75+mph vibrations.

Also, this story ran last night in Detroit:

I wish they would have ran one regarding the pickup truck vibration problems...maybe that will be next.

The gas pedal vibration is why GM did a MSRP exchange with me on my 2014 Silverado Crew All Star. They have no real fix for this, and never told me what caused it...after 4 service visits and a BBB case.

It takes a bit of time and effort, but the BBB is your only way out if you are unhappy with your truck...and it DOES work.

Keep all your service visit paperwork, start a BBB case, and work with your BBB agent. It is 100% FREE.

That's because the guy that got the story out has a Yukon, so that is all they concentrated on. In the original article they got a mention that the trucks have a vibration issue, but never got into it any further.

Since the truck vibe problem appears to be bigger than the SUV buffeting/booming, then I think somehow a truck specific story needs to get pushed to the media.

I mentioned this once before, but I don't think anybody followed up on it, but if someone has a vibrator in the Denver Colorado area, there is a consumer talk show on KHOW radio (Tom Martino troubleshooter show) that likes to help with stories like these. Every Friday they have "car day" and tend to focus on car problems. They have a couple pretty sharp people usually in the studio that run car shops. One is even the owner of Purifoy Chevrolet.

The show airs on KHOW (AM 630) from 10am to 1pm local time. Someone who has a vibrator in the greater Denver area should call the show at 303.713.TALK (303-713-8255) and see about getting on the air. You can call anytime and they will schedule to get you on the air if you like to tell your story.

Well Ive got 9k km on my truck,stock tires were swapped out for Goodyear Wrangler Duratracs at 4k kms in September.

All my driving since putting new tires on has been back roads and gravel.....hunting season.

Never had it on major highway at higher speeds till yesterday.

Surprse surprise vibes at 115km/hr and up.

Does not feel thru steering wheel as much as thru body itself.

Manual on tranny from 5th up has same result.

In the past with the 20" rims I've found mud built up on inside of rims to be the culprit(with the former F150 as well as these) but in this case there was little.

Only other thing was I had my roll top cover extended....don't do that often.

Maybe caused some different turbulence.

Tires are getting checked today....I'll test the truck after with roll top rolled up.

Well I just got off the phone with my service manager. My truck has been there since Tuesday. They are telling me the drive shaft has to be balanced, which he says will be done by adding two hose clamps. This is trip #5.

Obviously I'm going to give them a chance but from reading through the replies on this thread it's not going to work.

Has this worked for anyone?
