Well i have been reading this forum for quite awhile hoping gm would find a fix but so far i havent heard of one. My 2014 silverado cc std bed 4x4 has vibrated since i got it new. I had dealer check it when i took it in for its first service. I added a rc leveling kit with blovks in the rear along with after market wheels and bigger tires. The truck vibrated with both sets of wheels and tires. I put the stock wheels and tires back on for service, they had 3k on them. The dealer rf balanced tires and returned truck. Vibe still present. Took truck back toagain and fix the clunk in the drivers seat when turning. Truck returned and vibe was still there and had to order part for seat. When i took it back 3rd time to have part for seat put in i advised them that vibe was still there and stressed that it was more prominent above 70 mph and even left water bottle in console for them. Well when i picked the truck up i asked what they did about vibe and they said nothing because service mngr said his truck vibrates the same. Ghey put on repair order that they couldnt recreate the vibe. The seat was fixed though. The 2nd and 3rd time i was given a 15 cc short bed and it vibrated worse than mine and i informed them of that. Also all 3 times they only drove truck approximately 3 miles each time and there is no way they got it up to 70mph. I dont drive highway much so i dont notice it all the time but one time at approx 2k on the truck i was on the interstate and thought the truck was going to fall apart but it has not done it that bad since.
At this point i have just under 8k on the truck and not sure what to do at this point or just wait and hope for a recall or fix, any suggestions?
