Shake or Vibration Issues

[Mitsuboost30]

Just picked my truck up after its first visit to service for the vibration. They RF balanced all 4. One was 29 grams out. It does ride better however I will be paying special attention for more vibration.

I have also marked my tires/rims after the visit.

[Mitsuboost30]

 

My truck (2015 Sierra All Terrain) recommends 35lbs. in all four tires.

 

EDIT: I have 265/65's on 18" rims.

 

 

My 14 & 16 all terrain with the 20s both called for 32psi

 

I have 275/55/20s

Calls for 32psi

Furman Chevrolet in Brandon. They have been pretty good and have seen and dealt with them similar problems

 

I phone sucks sorry

Haha! We live down in North Port, an hour away) and had to go all the way to Rivard to find a smooth truck (We BBB settled for a replacement). That didn't last long - it's currently up there for its final repair attempt with the engineers. They replaced one tire and claimed within specs. How is one tire the problem when you Have T1 AND T3 vibrations........? LOL! Had another noise that the service manager confirmed and the engineers "could not duplicate", SM was pretty upset about that, he heard it! So needless to say if you go all the way with your truck the engineers they will send will be pretty much useless. This is the SECOND final repair attempt we've done on TWO different trucks. They come down, stay a day, replace a tire and claim fixed. My theory is they see "vibration issues" on the service form, come down, claim it fixed very well knowing there's nothing that can be done anyways. So we'll continue on with the BBB process and push for a buy back. I'm not doing this for a third time - we're expecting our 2nd child in 17 days and I'm not putting up with this running around with a newborn and a 6 year old!!! Good luck!

Anyone have an issue with the BBB just not getting back to them? Ive been working with them for 6 months now and we are finally down to the last step which is arbitration I believe yet no one has called me in 4 weeks and I call/email every couple of days with no response. Im getting extremly annoyed with the BBB and their lack of customer service....they are almost as bad as GM! I guess you get what you dont pay for!

Yes, I've had the issues. I found they do not reply to phone messages or emails. Last week I sent 3 emails and 4 phone messages. The only way I was able to talk with my guy was to keep calling and he finally answered his phone. I really feel this system is designed to wear the customer out until we finally give up! Good luck with yours.

looks sharp, definitely post it now that you've had work done!

 

 

That's nothing, wait till you see my new car LOL

 

No more Mercedes, traded it in for an Aston today ;)

I have noted a couple of things that might be related to my vibration. One was tire pressure; less vibration when pressures are below 30lbs, like on a cold day. I believe it to be a dampening effect. Second, M5 vs M6; less vibration in M5. But I wonder if this is because it also keeps the engine in V8 (vs. V4). I am wondering about a couple more theories(which is all I have because GM doesn't give a damn). One is related to outside temperature. Could the differential fluid viscosity be higher on a cold day, thus reducing vibration? The other is related to cab load. I believe the vibration could not be reproduced during my BBB arbitration because there were 5 adults in the truck (or an additional 500lbs over what is normally in the cab). The GM engineer noted it would dampen vibration.

You know, I've told 20-30 folks about my issue and talked to a few that have it as well. At some point this has got to start hitting GM in the wallet (unless they are just stupid).

This checklist might be useful for a few:

The harmonic balance is off when it goes into V4 Mode (which you force off with M5). You can feel this vibration the best when its in V4 mode, low RPM, and highest load possible without it changing to V8 mode.

 

I can tell you my bent axle shaft on my trailer vibrates less when there is a load on them. Differential Fluid shouldn't make a difference.

 

 

 

 

Someone with this issue should put a go pro camera under the vehicle near the bumper looking at the rear axle.

All,

GM was great. They agreed to do a $5,000 trade in allowance on my 2015 Silverado 5.3 DoubleCab 4X4 LTZ. The truck had 4,000 miles on it and the vibration was unbelievable. It would make my wife car sick. I had to drive 6, yes 6, 2016s before we found one without a vibration. I ended up "eating" $7,000 to get into a 2016 but I felt it was worth it because I had a $48 (sticker price, not what I paid) truck that my wife couldn't drive in. 40 miles on the truck and it has the same nasty vibration from 70MPH and up.

 

All the dealer wanted to do, was keep road-force balancing the tires. I thought it was ridiculous. Rather than wait weeks for an appointment, I paid $2600 for new aftermarket rims and tires and I'm stuck with the exact same vibration. I am now $10k into this mess. Do yourselves a favor and warn people.

 

I have started this website as an attempt to protect others from buying a Silverado. It will take a couple of days before it is up.

It would be great if you could mention that the Yukons/Tahoes/Suburbans/Escalades have a buffeting issue that may be related to the vibration.

hey Bill, still waiting on pics of the new tundra

Millions on the internet

Anyone drive the 16s and get the vibrations?

Will do!

Yes. I just posted that my 2016 has the exact same vibration that my 2015 had. I also noted that I had to drive 6 trucks before we found one that didn't have the vibration. Unfortunately, after about 40 miles it had the exact same vibration and I'm stuck with it.

If I was going to take a 10k hit then there is now way in hell I would have bought another chevy after going through all the trouble.
