    My crap Goodyear ties were changed to Michelin. No change in vibration. Sent from my iPhone using Tapatalk

    Nothing in the center console or floor. Just the passenger seat. And if I have the baby seat in the back you can see it shake a little. When baby is in the seat it doesn't shake. Kinda weird. Mostly since it comes and goes at random. Sent from my iPhone using Tapatalk

    3 sets of GY tires. And now a set of Michelin. No change in vibration. It is only between 75-85. Intermittent and you only feel it if you place your hand on the passenger seat. Service manager says the GMs answer is "truck is operating as designed" then goes on to say "not saying you have to like how it operates but that's all we have right now". I say it is a conspiracy to get people to drive under 75 to save fuel. Let us know how the new rear end works out in that High Country. Sent from my iPhone using Tapatalk

    GM put 4 Michelins on my truck and I still have the vibration. Talked to the service manager and he says they no other fix right now. Still researching with GM. He also told me they were told to not use Michelins anymore. They are supposed to use continental now.

    Picked up mine today. Michelins gave it a better and smoother ride. Vibration still there. A little muffled. But defiantly still there.

    I smell a class action lawsuit.

    Demand that they put new tires. Anything other then the Goodyear LS2. continential or michelin have the best ride quality and tread wear.

    Thats what I told them. Since GM has not officially admitted to the problem they will all be clueless until GM figures out how to fix it. Some are having driveline vibration and some tire vibration. They say mine is in the "tire range" when they hook up the computer that measures it. So hopefully this will be it for me.

    They said they "road force" balanced them after they drove it for 20 min or so. They say they only balance the tire after it is at operating temp.

    I will be picking mine up from the dealer today. They changed all for tires and put on Michelins. The service manager said he drove it before and after and said it is a night and day difference. We shall see. Ill have a 35 mile ride home from the dealer to determine if it is fixed. Will let y'all know. On the positive side... I have brand new Michelins. The truck has 12600 miles on it so I wont have to change tires for a while.

    You have got to be kidding me!

    To my understanding it is the tires. I will know more when I drop the truck off. I do know that they were working with GM on the issue and that the truck they did had for a week or so that they worked on, they just changed the tires and that fixed the issue. It is somewhat believable because GY tires SUCK! And as I saw on a previous post on here someone switched to Michelin tires and they had no more vibration issue.

    @ JAC50 The service manager at my dealership in FL called me to have me bring mine back in. He says he fixed the problem on another '14 and says that it was a night and day difference. He needs to have my truck for 2 days. He needs to drive it and take the vibration hertz and g-force readings to make sure it is in the tire range frequency , then they are going to put Michelins on it, drive it again to take more readings to compair. Last time it was there they did the same thing and said the readings show it is a tire issue so they "force balance" all 4 tires and sent it home with me. That didnt fix the issue so hopefully the Michelins do. The fact that mine does it intermitently, I dont think it is a tire issue but we shall see. This will be the 5th time in for the issue. So far 3 tires have been changed and balanced 4 times. I will post any changes when I get it back. Will be droping it off on Monday.

    That vibration at 30 mph could have something to do with the fuel management system. (engine going to 4 cyl) I notice it only when mine is running on 4 cyl. It just sounds like a low rumble.
