Shake or Vibration Issues

mgoodling44 · September 15, 2016

~~We have Full warranty until 2022 see it is all on GMs dime~~

For me the dealer has been pretty good it was their suggestion to dig further into it even though they found nothing wrong with tires and visual check and a test drive, so far they are willing to go the extra with out hesitating. but then again we bough3 vehicles from them so far in the last 2 years. truck, sons car and daughters car. each time we have had no issues with any requests. If it drags on I plan on just keep on returning and documenting the vibration no getting up set each time just stay polite. service advisor called to apologize today for not having a solution and if it was OK too keep it longer to hook up the test sensors. As long as they seem to be trying to help that's is Ok as they know we will be back next year for a new car for my wife. So far I am on good terms with the sales manager, finance manager as well as the service manager

~~not sure why I see line in everything sorry...~~

Best of luck. Sounds like you have a good partner to assist with your concern. I have a sneaking suspicion that you will be back to forum, with similar stories like the 600+ pages that you read over in this thread.

I hope it works out for you. Please keep the folks informed, as there are LOTS of people affected and praying for a valid solution.

Got my truck back after almost 5 weeks in the GM Shop, they had to replace the Transmission because it sang so bad in over-drive that you had to keep the radio on so you would not hear it.. now the freakin A/C goes out within 2 days of getting it back!! can you believe that? the A/C goes out!

1643

And the damn thing still shakes like a Cheap Hooker at a Frat Party!!

All this on a truck with 35,000 miles on it.

I feel like a damn fool for buying another 2015 Chevrolet Silverado 1500.

Do the 2500/3500 models have the same issues?

I had the battery die on mine last Friday and it was covered under warranty. I have a noise in the front that sounds like a "growl" according to the service advisor.

The loaner 2016 CC 1500 has 100 miles on it and it has the exact same vibration as mine did before they replaced the ring and pinion.

I was thinking of trading to a 2017 with the 8 speed and the 6.2 but not if they too have the vibration.

I had a coworker drive it and he didn't notice the vibration until I pointed out where to feel it in the steering wheel.

Now this is different than the shake. My cousin has a 2015 chevy crew cab and it has the chevy shake as some are calling it. It is different than the vibe in my GMC.

This is so sad.

My Canadian friend, best of luck. I'm at the point that I don't trust the dealership. I have found that they have inexperienced "techs" and that they are directed to follow a protocol that leave the consumer (you and I) holding the money bag. In my two month of ownership of a GMC 2014 Sierra, it's been nothing but a major disappointment.

To give you the bottom line, here are your options:

1. Continue to play the cat and mouse game with the "stealership". You will end up forced to buy/replace parts that their "techs" claim is the issue. Probably end up in $2-$3k range before you can get a lawyer and file a lemon law claim. By the way, at this point, you can't trade in, because all the service records are available to the other dealerships on your truck that show all the work being done and the owner's (you) service requests.

2. Try and figure it out on your own. Find a good trusted person, with good tools, and diagnose yourself and do the work. Yes, it will take time and money, but it better than getting work done by the dealership. Be patient and just use good mechanical sense. Again, probably looking at $2-$3k for specialist/independant shops to assist, and again, you may still not have solved the problem. Risk vs. Reward. This is what I'm leaning towards.

3. Just stop now. Stop messing with it, cut your loses, and move forward. Sucks, but it is reality.

We (GM owners in the middle of this shi! storm) are left with nothing to do but suck it up. We made a bad decision for a bad product, and now we are screwed financially. The truck has so many good features, but the vibration/wobble is trumping the good things. Once you accept it, your decision making will be much easier.

At this stage of the game, you are damned if you do, damned if you don't. I can tell you that I wish my father (a GM diehard) was still alive. He'd even been disappointed, but a bet that he would find the issue and be able to fix it. He was master mechanic, and as long as i've been alive, he could fix anything. Literally, a mechanical genius.

So, I'm probably going to eat about another $3k, just to determine if my pride is worth is it. I'm self diagnosing, in hope that we can find a fix. If you are not willing to commit, simply trade it in for another brand (sorry Dad).

Best of luck. Sad, but true....

Update. Stealership still says "tires". PICO scope show tires are the problem. So, now....it's back to the tire dealership to fight with them to get (2) new rear tires that the GM stealership claims that they can't balance. This shoudl be fun.....

Now keep in mind, as I drove home today, driving about a 48 MPH, the vibration started...so I ever so slightly pressed the accelerator, and it stopped, then picked up again. Can someone explain to me how in the world this is tires?

But, at this point, I've chosen this path. So round and round we will go.

Oh, I might add, another $275 down the drain because the "tire issue" isn't covered under warranty, and I didn't buy the tires from the dealership.

I had my new stock size 20" duratracs re-balanced today. The rears were an ounce out after 300 miles. Truck has 550 miles on it. While they had it on the lift i checked the U-bolt torque. 45 lbs. ran them up to 80 lbs. much less shake after 70 mph and much smoother on the road I live on. Much less aftershock bounce when hitting sunken manhole covers in town.

It's worth a try to check your u-bolts. I will report back after awhile to see if it sticks.

You should have never handed over the dealership any money. Stand up to them next time and check ahead if they are going to charge you for a warranty issue. If they do then argue back or take your truck to another dealer.

I got my truck back yesterday but traffic was too heavy to get it up to speed last night for any length of time. I got close to 70 and didn't feel anything. I'll get on some open roads today. I was very pleased with how my dealer is handling this so far.

Day 2 after torqing u-bolts. Ride on rough, broken pavement is much smoother. Bumps and thumps are cut in half. Dirt roads and washboard are tolerable again. I still have a bit of shake at 72 but it is also reduced by 50-75%.

Just out of curiousity, what is the u joint bolt torque specs?

15-20lbs is what I see online for older trucks.

I had some issues with vibration right before the trans failed. I think it went into a limp/safe mode and would not shift out of first gear. I had lots of warning info on the dash.

I had it towed to the dealer. No idea what they will say. I honestly don't even want the truck anymore after it left me stranded.

Bought a 1/2" torque wrench, set it to 40 ft/lbs and went to work. Now if they ever actually looked at my truck, they'd know the bolts are way under spec, right? 40 ft/lbs and I had to go 1 - 1/2 turn before it clicked. I've been to them 5 or 6 times for this crap. FFS GM, that is just lazy. So I then set it to 70 ft/lbs and tightened corner to corner X style. Then I took a ride. Suspension feels tighter and rolls a lot easier over road imperfections. I'll leave it like this for a few days, then possibly up to 79 ft/lbs.

I still have AFM vibe and these Continentals that came with it are trash. Honestly, GM should go the RAM/Dodge route and put fatter tires on these trucks standard.

That sir, is a sad image.
