Do you know exactly what was done to the Drive Shaft to fix the vibration problem? I'd like to explain the exact needed fix to my dealer.
Thanks!!

I notice a shimmy/shake in the engine/drivetrain coming out of first and second gears.
Also, a intense vibration hits every once in a while, usually when dropping down into cruising speed, underneath the passenger glove box, and works itself out in 8-10 seconds. This happened even the day I drove it off the lot.
Very annoying for a $60k vehicle with only 3500 miles on it now.
I dropped it off at the dealer today with a list of problems, brakes squealing, iPod popping through USB, shimmy/shake, intense vibration, engine sputter at idle sometimes.
Geez, I wish they would give me my 2007 I just turned in back to me, it never had a problem, well...actually a few wiring and electrical problems.
I am from GM Customer Service. Can you please keep me informed on how it goes with the dealership? Thank you,

New set of Michelin LTX M/S2 tires, perfect road force balance this time using the correct weights unlike what the dealer had done and scraped the wheels the first time, and was off. Lost the some extra A/T tire squish & wiggle, felt crisper on the road, and cut road noise. Gas mileage even seemed to perk up.
Problem? Immediately clear, after a little of driving, that the truck still had had the shame vibration and shuddering, exactly as before. Not a tire issue, as I hoped not to see but pretty much proved...makes sense, given how it has always felt drivetrain/powertrain related.
In the last week, now, for whatever reason, it's shaking so badly, and quivers so hard, it's just bizarre to drive. Feels like an old, ragged truck with 200k that's been abused. Never been off the highway or driven hard. At the same time, it's also started shifting bizarrely, especially with downshifts that send the tach dancing and other shivers through the truck as you decelerate/downshift. Feels like it's stumbling, in varied degrees.
And...maybe my imagination, maybe not...something is up with the steering. All of a sudden too, seems to have loosened up on center and the other day turning it in a parking lot, seemed to be loose, then bind up, then back to loose again. Not enough to even mention this one, but enough that I've been wondering.
The shakes are worse. It was shaking and shuddering so badly today driving to work and back on the same new, smooth 2 lane roads, almost felt like it had a bad miss and something wrong with the trans. Oh joy. 3500 miles.
Going to another dealer locally on Thursday. Never been there for service before, but I hope 1) it continues to act up just as badly and 2) they can figure something out, beyond "everything looks tight and normal underneath..." Now, how to properly explain it to them...
Transmission, driveshaft, and so on. Joyous. Again. Reminds me of the days when I had to drive around with a datalogger in my '09 Malibu to help show off the shuddering transmission. That was nothing in comparison to what this truck does.
I didn't get his business card and can't remember his name.
Thanks
But all I here about are the endless complaints (on this and other web sites) about vibrations and the inept dealerships that these poor guys have to go thru. Its no wonder this company had to be bailed out.
I am sure glad I visited Edmunds. And thank you to all the Tahoe owners who have opened up about their lemons. It used to be that GM could not build small cars (Vega, Cavalier,Chevette, Nova Corvair,) I could go on. But they Could build the big V8's.
In the 70's and 80's I drove big impala wagons. Then in the 90's Tahoes. But to hear these current problems (Gm can't seem to make a wheel round) and then be ignored by the company is too much.
I can't give Government Motors any more of my money
I am from GM Customer Service. I apologize that you had a less than optimal experience. Did the dealership find the fix to your vehicle or is the concern still present? Thank you,
Mariah GM Customer Service
Has anyone found a fix for this issue? This thing shakes so bad you don't want to drive it and it is embarrassing when you have passengers with you. This vehicle is way to expensive to ride like an OLD dump truck.
How about GM what are you going to do about this issue?
I apologize that you are experiencing an issue with your vehicle. Can you please email me so I can get more information from you so I can look into the situation further? You can get my email by clicking on my name. Thank you,

It is definitely something in the drive train that can reach resonance. I tried Emailing the GM ID in #72 and it was returned.

This is getting ridiculous, throw in a rattle under glove compartment, bad pull to the right, iPod USB popping/crackling noise, and this 2010 $55k Tahoe is a lemon for sure.
Oh and my navigation system quit working today!!!
tires and rims
ball joints
brakes
sway bars
shocks
driveshaft
axles
pinion
transmission
most of those problems will go to the driveshaft angle and balancing. go to a transmision shop maybe they can shed some information on this. pep boys will also know about this. most 4x4 shops also can add information
good luck

I'm not calling miami and I am certainly not driving to miami. The only thing that makes sense to me about your post is your recommendation for a quality dealership.
Good techs and engineers solve problems, everybody else just gets in the way.
My dealer seems to have fixed mine. I had bought mine Certified Used and they had a new but off brand set of tires. I am a mechanical engineer and I swore it had nothing to do with balance and when they balanced my tires the first trip back without it working I was furious.
The second trip back they had it two days. When I went to pick it up I found they put new tires on it, Goodyear Wrangler AT/S. Look to be the same ones that come stock. I was immediately apprehensive and told them so. I took it home and with almost 2K on it since I haven't been able to reproduce it. They said one of my tires was out of round. How they could tell that, I don't know.
So, to make a long story short, mine seems to be fixed.
So glad to hear you found the problem. And it was the tires! A lesson for us all.
Goodyear probably built a batch of junk tires and tried to pass them off. It happened to me on a vehicle that came with goodyear Integrities and a new set of Michelin Cross terrains solved the problem (dealer supplied after much prodding and aggravation) I will never buy a Goodyear tire after that.
Seems to be the truck is trashing the tires and that makes things worse. The tires are not initially faulty.

You nailed it. GM has used that tactic many times. Now american tax payers own a worthless piece of stock.
No the dealership now says that the vibration that I feel is normal now. I am contemplating do the Lemon Law.
Can you email me your service request number or your VIN so I can look at it further? You can get my email by clicking on gmcustsvc. Thank you,

Attention: Proceed with this bulletin ONLY if the customer has commented about this concern AND the EI number is listed in GMVIS. If the customer has not commented about this condition or the EI does not show in GMVIS, disregard the bulletin and proceed with diagnostics found in published Service Information. THIS IS NOT A RECALL -- refer to Service Bulletin 04-00-89-053A for more detail on the use of Engineering Information bulletins.
This bulletin is being revised to add tire RPOs QST, QIZ, QAS, QAN, QJM and QJP. In addition, step 11 has been revised to request the 11-digit DOT number of the tire. Please discard Corporate Bulletin Number 07-03-10-013 (Section 03 -- Suspension).
Condition
Some customers may comment on a vehicle/tire vibration.
Cause
GM Engineering is attempting to determine the root cause of reported tire vibrations on vehicles equipped with P275/55R20, LT265/70R17, P285/45R22, LT245/75R16 or P265/70R17 tires. GM has a need to obtain information during diagnosis and BEFORE repair. This information will be used by engineering to "root cause" the customer's concern and develop/validate a field fix.
If the customer's concern can not be duplicated -- disregard this bulletin. If the customer's concern can be duplicated, complete the following steps. Be sure to note the following information on the repair order:
Verify that the VIN and mileage listed on the repair order is accurate. Describe the customer's concern (i.e. shake, buzz, roughness, tingling). Note when (mph, idle, accel, decel, etc) and where (steering column, seat, etc) the vibration is felt. Document the tire size and manufacturer of the tires currently on the vehicle. Inspect the following components to verify that they are in good working condition. Note any "faults" on the repair order:
• tire/wheel assemblies
• steering components
• suspension components
Install the J 38792-A (Electronic Vibration Analyzer -- EVA) sensor to the component identified by the customer as the most respondent to the vibration. If no component was identified, install the J 38792-A sensor to the steering column. Select a smooth, level road and slowly accelerate the vehicle up to highway speed. Observe the vehicle for disturbances that match the customer's description and note the following conditions:
• Vehicle speed
• Engine RPM
• Transmission gear range and specific gear
• Vibration frequency reading, detected by the J 38792-A
If the sensor was originally placed on the steering column, and the vibration seems to excite a particular component of the vehicle more than the steering column, move the J 38792-A sensor to that component and repeat steps 6 and 7. Does the frequency data clearly fall within the tire/wheel parameters? (Refer to Symptoms -- Vibration Diagnosis and Correction, found in SI).
• NO -- continue to diagnose and repair the vibration not related to the tire and wheel assembly. • YES -- proceed with Step 10.
Using the HUNTER GSP9700 Roadforce/Balancer, measure the roadforce variation of each tire/wheel assembly. Also, with the original balance weights still installed, measure the inboard and outboard imbalance. Record the findings on the RO. Record on the repair order, the 11-digit DOT number found on the rim flange of the tire.
PRIOR to making any repairs, contact the engineer listed below with information from your diagnosis. The engineer will provide direction to repair the customer's concern. For vehicles located in SE Michigan, the engineer may need to physically inspect the vehicle
I would like to look into this further for you, could you please email me your VIN?
Thank you,
