Shake or Vibration Issues

[dave07]

What did you pay out the door? Or I guess a better question would be what was the agreed upon price of the truck with all the accessories?

That my friend is a long story... however I will keep it brief. they screwed up in their online ad (forgot to add the value of the accessories to the cost) in dealership they wanted $53,000. probably would have got it for about $51,000 had they not made the mistake, because of the mistake, I paid substantially less (consumer protection laws require them to sell it for the advertised price, mistake or not), not that that is of any consequence, because it is the current cash value of the truck that is in question, not what I paid for it due to their negligence.

 

The extended warranty is not included in that cost either.

So, I'm trying to get up to date on this issue. I've scanned this thread but there are 547 pages! Can I ask some simple questions, which might be helpful for others trying to gather info on current status.

 

1. Is the vibration resolved by changing to some higher quality tires?

2. Do the new 2016 trucks have the same problem?

3. GM has not been successful in tracking down the source of the vibration, in most cases?

 

thanks

1. No

2. Yes

3. Correct, unsuccessful in fixing the issues

What is a 3rd order vibration? I don't understand why they can't fix this crap.

Simplest terms a thrid order vibration is when the vibration frequency is 3X rotation frequency of the part causing the vibration. Example: tire rotates at 10 rotations per second or 10 Hz, First order vibration detected at 10 Hz is usually a mass imbalance, Second order vibration is detected at 20 Hz, Third order vibration is detected at 30 Hz, and so on.

Well I had an update call today from the dealer stating that gm thinks it's no big deal. I call bs!!! How is it not a big deal when all you need to do is Google search silverado shake and tons of links pop up and videos. We all must have no idea what we are taking about. So they want to run another picometer test and send it to gm. Guess who doesn't have thier truck? This guy!!! Has anyone towed a heavy load with the shake? Does it shake more? I'm starting to wish I never bought this truck.

My truck shakes less when towing.

Probably because you have substantial tongue weight on your hitch which has the same effect as load in your bed.

Actually, it was small. A 4x8 UHaul trailer with a sofa and it titled up slightly, but it was enough to make a difference.

FYI if one happens to go through the BBB and a repurchase is granted you can go after every penny invested in the vehicle. This includes wheels, lifts, tint, etc... It's part of the "collateral charges" you may be entitled to if the BBB finds that the vehicle is in fact a lemon.

You are in for a long and very uncomfortable ride.

1. No, because GM says there is no vibration issue

2. Apparently so, nearly a million hits on this site alone tells the story

3. No, because GM says there is no vibration issue

 

Some dealers are trying to help, mine has dumped me.

BBB arbitrator sided with GM (follow their funding and you'll see why)

State Attorney General's office will do nothing

Until this thing hits GM squarely in the wallet, they will do nothing

Bottom line: you're stuck...

Does changing to aftermarket wheels help?

Does it happen with the smaller 18" wheels?

Does it happen on both 4x4 and 2wd trucks?

Does it happen on all wheelbases - reg cab, DC, crew, crew long bed?

 

thanks

I bought a new 15 sierra 5.3 rcsb 4x4 at xmas and only got a chance to drive it 200 miles but it has no vibration. But I can tell these new fully boxed frames are very rigid and don't flex. Something tells me because of the nature of fully boxed frames all road , tire , drivetrain vibrations and harmonics are going to be transmitted to cab. This might be a crazy thought and probably is but maybe cab mount material will have to be rethought to cancel and absorb these harmonics better . Just a unscientific thought at best LOL.

Update: vibrations came back. Thoroughly disgusted with this truck's vibrations. On my drive yesterday morning, it shook so hard, it felt nauseating. GM lost their ability to build a good truck, imho. As there's no effective repair yet, the thought of ditching this silver colored turd is tempting.

 

 

The 5.3 and 6.2 are direct injection engines. Gas is not sprayed on the valves to clean them. The gas is injected between the bottom of the valve and the top of the piston. On the older engines the valves were washed with gas. Some people including me are using catch cans to try and keep the valves from coking. The valves can be cleaned using seafoam through the throttle body.

Lesson learned.

 

Sorry buddy, that has nothing to do with the Vibrations talked about in this thread. Your vibe problems sound similar to mine in that they come and go.

You are so right about come and go. Kind of like a bad girlfriend - stays around too long and comes back too soon.

 

so suffer another year, and hope you still have enough time left to file for it.

 

Im sure someone out there has aftermarket rotors by now..... I tend to doubt that they are the issue. I believe it was abominable that took is rear end apart and found the edges of the gear teeth chipping away... GM said don't worry about it lol.

 

Gas has nothing to do with it, for that matter I only use "top tier" fuels in shell, mobile, and sunoco. doesn't help me

 

 

 

This i agree with


I know people have used lift and leveling kits, but has anyone tried using a softer shock, and adding sway bars to reduce the additional body roll that would likely result. leaf spring clamps have helped some people.

 

just spit balling here

Yup, thought fuel would be the source but not even close.
