    Yes and it is bull. My High Country has vibration from 30 mph on up on smooth roads. At first they tried that theory, so I watched for it. I feel no difference at all in V4. In the wife's Z71 I feel no difference in V4 and hers has no vibration. The v4 theory is something they use to pacify you. Even if this is happening on some peoples trucks it doesn't do it on everyone's, and it doesn't on mine. I would ask them to correct it. I also upgraded from a 2008, a Z71 LTZ. Last week I drove it last week while the High Country was being checked out. It drives great and no vibration. The comparison of the good drive of the old truck compared to the crappy drive of the new hardens me in my resolve. Excuses for the vibration are not tolerated.

    My suggestion is short GM's stock. As tax payers we bailed them out once. We just as well make some money when they fold a second time. It took me two months and a call to GM to get them to even look at my truck. I am past checking tires now, they put the vibration measuring equipment on the truck and decided it was the drive shaft. I am waiting on the drive shaft now. I don't think it will be the fix but it is the next logical course of action. It looks like it will be a slow process. I am counting the days in the shop now, 30 full fills the lemon law requirement in my state. Serious suggestion; I give you this suggestion. You are in Ohio, a quick look on the lemon laws in Ohio included this "The vehicle has been in the repair shop for a total of at least 30 days" You past 30 days, ask for your money back or that they replace your vehicle with one that is acceptable. Do a quick google on the law. Your next step is probably documenting what has taken place and sending a certified letter asking that they replace or refund.

    You can blame the tires, and change tires till you find a set that helps masks the problem. Once you eliminate balance issues you are just looking for tires that can cover an underlying defect. I had the dealer put Nitto Terra Grapplers on mine when I bought it, and the steering wheel vibrates. So he blames the tires. Having used Nittos for 6 years I claim bs. We switch tires with another new truck and still vibration, maybe less with stock tires but still there. We put my Nitto tires on the truck we switched with and it drove smooth as glass. No vibration in the steering column, none. So this pretty much eliminated the blame the tire theory. I am disappointed with the new structured GM. I question if they are really the same company any more. I had a dream last night. I dreamed I was driving a Ford with a smooth ride and no vibration. I woke and didn't know if it was a good dream or a night mare. I do not want to give up on my Chevy's, at least not yet.

    What I have is a constant thing, and it varies depending on the road. It varies from a hum feeling to a tremble that will shake your hand. Yours sounds like a different issue.

    Not the tires, although the stock tires are junk. I have Nitto Terra Grapplers. They claimed it was the oversized tires. I had balanced them twice and told them no. We took my tires and put it on another truck. It ran perfect with my tires. With its tires I still had a vibration. So we eliminated the tires as a problem. My vibration feels like a hum in the steering wheel. It will get noticeable after 30 mph. Sometimes it is annoying sometimes not noticeable.

    A continual soft vibration or is it harsh. Mine has a vibration that ranges from soft to a bit annoying.

    I gave it to the dealer with a nice letter about the vibration and ride. The dealers service guys still said the ride was because of the High Country's rigid frame versus the Z71's. I also copied Chevy's news release they put out at the release of the High Country and underlined a few things. These are excerpts from Chevy's High Country news release; "A fully boxed frame with the main rails and major cross members formed from high-strength steel provides a rigid base for maximum hauling capability, as well as greater noise and vibration isolation – contributing to the Silverado High Country’s balance of segment-best capability and industry-leading refinement. The stiff chassis enables more precise tuning of the front and rear suspensions, giving the Silverado a more responsive feel with smoother performance and less vibration and shake, particularly on harsh terrain." The ride I am getting from the High Country doesn't match Chevy's sales hype. I am waiting to see what GM says.

    Last weekend I was trying to figure out how much the High Country vibrated and rode rough compared to the new wife's Z71. I looked for devices that would measure the vibration, they were all expensive. Then it I had an idea, one of my hobbies is photography and a camera mounted rigidly on a vehicle will magnify the vibration. http://www.flickr.com/photos/55888666@N08/12733014584/ I am not sure we can post links on this forum, but above is the video. Let me qualify it a bit. Mounted like this the camera would magnify vibration. The trucks do not vibrate this much but it I did it to give myself a comparison. Both cameras were mounted on the head rest mounts identically in both trucks. The new Z71 4x4 is on the left, it has a 3.5" Rough Country lift and 305/55/20 Nitto Terra Grapplers. It has 1200 miles on the truck. The right is the High Country with 285/55/20 Nitto Terra Grappelers. It has 5500 miles now. Edit: I should point out that the trucks were driven on the same road about 30 minutes apart, the Z71 on the left is slightly ahead of the High Country. The Cruise on both is set at 40mph. I took the truck in earlier this week. According to the dealers service department the ride is due to the rigid frame of the High Country. I am waiting to hear back through the Dealer from GM for an explanation as to why Chevy's top end truck rides so rough.

    I am not experiencing vibration when accelerating on either 2014 I have. The Z71 has a 5.3 and the High Country has the 6.2. I do not think it is normal. I have never had a vehicle that vibrated during acceleration that it was normal. Perhaps it is normal to the dealer because he has a bad batch of trucks that are doing this.

    I have the High Country, the specs on chevy's website just says it has an upgraded suspension system, it does not mention the Rancho shocks. I wonder what is in the upgraded suspension system? Is the Z71 off road suspension better? It makes me wonder, when I take it in I am going to ask what shocks it has on it. @Silver Spaceship I notice the seat vibration to. On some roads I have noticed and actually felt a small vibration in my neck from the seat. I passed it off as not that noticeable but if your felling it in your head something is wrong. What jumps out at me about the ride is that I catch myself grinding my teeth. Like you say with the steering vibration it has gotten better with time. 5500 miles, maybe by 10,000 it will be gone. I have made a management decision, if the drive does not improve I am going to put a lift kit in the truck and put some nice big aggressive tires. It if it is going to ride like a jacked up truck it just as well be a jacked up truck. If I can't have the ride I want I can sure look good driving it.

    I had the dealer put Nitto Terra Grapplers on the truck when I bought it. Mine is the High Country, I oversized the tires to 285/55/20's. They are the same tires, size and brand that I have had on my 2008 LTZ Z71 since I bought it in 2008. They have been great tires. The wifes new Z71 LTZ has the same vibration at highway speeds. We lifted her truck 3", changed to Fuel Rims and 305 Terra Grapplers when we bought it. Road Force helped and I think it corrected some of the vibration, I have a 300 mile drive this afternoon and will test it out on that ride. I do not believe the issue is related to the tires, although it is contributing to the underlying problem. The steering column is just transmitting to much vibration in the hands. This truck is my 12th chevy truck in my 35 years of driving. I have now bought new 7 chevy pickups an 86, 89, 92, 94, 08 and now 2 2014's. Of all of the new trucks only the 86 4x4 rode rougher than the 2014's. Is it just me and I am losing my memory or just getting picky as I get older? Or do the new 2014's really ride rougher than the older trucks? My opinion is they do. My next step will be to check the drive shaft. I am also thinking about getting rid of the stock shocks on the high country.

    The dealer Road Force machine has been down for days. I called the local tire shop and asked if they had a Road Force Machine. They did and I took it in. All the tires were in spec, however they rearranged the tires for a better ride. Helped a small amount. However--- The tire shop tells me that others have been bringing their 2014 in and they had several 2014 chevy's in today with the same problem. The consensus seems to be that it is an electric power steering issue. The new system is transmitting to much of the road and truck vibration right in to the hand of the driver.

    My 2014 High Country has a bit of vibration on smooth roads in the steering wheel. It is two months old now, and I noticed it at all speeds when I first got the truck. I balanced the tires and now only feel it starting at 60-70 mph on smooth roads. I have Nitto Terra Grapplers and thought maybe that was part of the issue. But I have run Nitto's on Chevy's now for 6 years and had no problem. I bought the wife a Z71 4x4 LTZ Crew Cab Short Bed. Put a 3 lift and 305 Terra Grapplers. The two trucks mirror the drive of each other. Both have that subtle vibration at higher speeds. I am going to have the dealer Road Force balance the tires again on the High Country. Then check the alignment of the shaft. It has actually gotten smoother as it has broken in. But I have a theory, to see what some of you think? The new electric power steering handles differently than the old style power steering. It seems more sensitive. I think that the vibration some of us are feeling is probably not much different than our old chevy's. It is just not dampened with the new electric power steering. Vibration in your hands is more noticeable than say vibration in your seat. ( A few things I have found that smooth out the vibration, set your air pressure to the recommended pressure in the door plate. Second; the telescoping steering column. I have found at certain settings it will have less vibration.)

    I bought a 2014 High Country and it has done the same thing. At first it would do it every 30 miles or so. Two months and 5200 miles it does it rarely now. I only hear it every day or so. It sounds like it is the window getting hit. I had my hand on the radio once when it did it. I could feel the pop. I think it is the truck dash settling in. I bought the wife a Z71 4x4 LTZ and have only heard it twice in 500 miles and it isn't as loud. It seems to have gone away, either it was the cold weather or it just settles in.
