I have a 2007 Silverado LT 6.0Ltr, 4X4 ( not classic ) I "had" a tinny, obnoxious vibration on acceleration at exactly 1500rpm. As recommended on another website, I went under that truck at the passengers door and located the screen mesh on the exhaust pipe. I moved this screen mesh back and forth for about 15 seconds. Went out for a drive and the vibration is gone. Mmmm....what's up with that. If the vibration returns , I'll try it again.

On my 2010 Silverado under the passenger side the dealership replaced the heat shield because of an improper assembly the shield would rattle.

I have taken my 2010 Silverado to the dealership once more today to see if the can remedy this situation. As of yet all that we have done is new tires, rear shocks, checked front suspension, steering, driveshaft, and balance of tires. I get the feeling that I am about out of there patience in terms of them willing to look into a problem that they can't seem to find. I have taken them personally in the truck on multiple occassions down the road to have them experience this "jostle" of the entire vehicle as it traverses over bumps or expansion joints in the highway. An up/down motion of the vehicle is normal but when the vehicle wants to shake left and right and cause the entire vehicle to move in such directions, I no longer feel safe to operate. I have driven 4 different Chevrolet Silverados to almost 300,000 miles each and the 2003 that I currently also operate still rides and traverses smoother down the road than the new one. Figure that one out. We also drove a brand new truck off the lot on one occassion to see if the problem that I had was in the new truck. Of course we could not replicate that symptom in the new vehicle and they service technicians complied. Ugh, you know at the end of the day you shouldn't have to do this. Isn't that why I bought a new vehicle in the first place. NO PROBLEMS.....HMMPH. In regards to you opening a service request what information is needed and what more does that do than me returning to the dealership again?

For the service request, we would be working with the dealership towards trying to resolve this concern with your Sierra. To get it started, we would need your name/Edmund's username, contact information (phone and address), the last 8 digits of your VIN and current mileage, and the name of your dealership. Since you've been working with your dealership extensively, your case would be forwarded on to your district specialist.

"We also drove a brand new truck off the lot on one occassion to see if the problem that I had was in the new truck."
Wonder why they had you do that if you have a valid complaint about your "warrantied" truck? Sounds like a quick, convenient way to say "see Evan, they all do that so quit complaining!"
Was it the Sales Manager or the service department's idea to "drive a like vehicle"? I'm guessin' it was the GM Dealer Sales Manager.
In addition to other quality issues, my 2011 Sierra's steering pulls right and jumps a bit over bumps. It has since new. I don't care if GM has "run out of patience" with me. I'm going to keep telling them to correct the numerous problems with the new truck.
You're exactly right; why did we buy a new truck?
My old truck ran better!

The TSB I was referring to is "#PIT3009M: Suspension Vibration Or Frame Beaming At 40-60 MPH." Interestingly, this TSB describes how to test for Frame Beaming (by placing 500 lbs in the bed over the rear axle and seeing if the vibration goes away). More interestingly, if the weight makes the vibration cease, the remedy is to check and upgrade the rear cab mounts to a newer design. Some 2011 models already have the new mounts, mine did not. It seems strange to me that the 'fix' for excessive vibration is to attempt to dampen it in the cab. Doesn't seem like a Root Cause Analysis has been done on this problem (or the root cause is too costly to repair). The dealership also said that three of my tires were out of balance. The service guys were very helpful on this visit, but they were careful to tell me that this is just how that truck rides because of the soft suspension and the off-road tires. Funny, but my 04 GMC crew cab had the same tires and drove smoothly all 172000 miles. Unfortunately I am at 1700 miles and the vibration is still there. I feel it in the seat, the gas pedal and the steering wheel. If I knew that I would have to be in the shop so much with a brand new truck I would have kept my '04 and saved myself 40 grand.

I went back to the dealer for the 5th or 6th time about this and they noted that the body mounts were the "revised" version and that my truck is operating normal in terms of what the technicians have said. I am not satisfied and requested to have the issue "escalated" to GM to move further. I was told that the request will be fulfilled by a GM representative and/or engineer speaking with the technicians to evaluate the situation. I may then receive a call but not too likely if my truck is "operating as normal" in accordance to the technicians that have worked on it. I have taken numerous people in this vehicle and they all agree that something is not right. New tires, new rear shocks, checked alignment, balance, squareness? of truck, and taken two technicians for rides in which they agree that something is awry. Yet after all of these visits, I still have a jostling, jouncing, tramming, uncomfortable, and potentially unsafe vehicle to operate. I really am at wits end and am waiting till the end of this week to see if the GM Representative or Engineer will contact me or the dealer. This is really inexcusable. I have personally had 5 GM vehicles and operated 4 Silverados from 0 miles to well over 260,000 and never had this rattle of the cage. I drive an 2003 silverado that has 202,000 miles on it with front shocks in need of replacement that still goes down the road with better conformity than my 2010 with 18,000 miles. Is this lemon material? I heard that the buyback alternative is a real stickler, yet that can't be worse than what I have right?

Does anyone else have a 2011 gmc 2500 6.0 gas engine where the doors, cab mirrors shake and vibrate? I have taken it to four dealers and they say oh no this is just part of how the truck runs. I had to tell them to check the motor mounts and the service guy said we cant just start checking things?
