pm26 - I did not choose the best words - GM is probably aware and is stonewalling/covering up as you imply. hvill - I have the double cab, 18 in wheels, Goodyear wrangler tires,s 5.3 liter engine. A distinct and noticeable vibration is felt most strongly on driver's side at speeds between 65 and 75 mph. Primarily when applying power, but can also be felt when coating after cresting a hill, for example. Tires have been balanced and force balanced; one wheel was out of round and replaced. I have no idea of the quality of the balancing efforts. Very noticeable and annoying vibration. For what these things cost, the ride should be smooth. My 2004 Silverado crew cab was smooth. I should have kept it.

My dealer's service manager drove other new SIlverados on their lot like mine and found the same vibration to exist. They are now claiming it is a Chevrolet engineering issue. I spent some time speaking with the Chevrolet Manager at my dealer and with the Chevrolet Customer Care people. The Chevrolet Manager at my dealer said that they were receiving other complaints similar to this. My impression is that the left hand doesn't know what the right hand is doing. Chevrolet seems to be completely unaware that this issue even exists. Nobody wants to take responsibility. No wonder GM went bankrupt.

I just bought a 2014 Silverado, with the former "extended" cab setup, 5.3 l engine,18 inch wheels, Goodyear tires. I'm thinking I should have run away...when I first drove the vehicle, on the interstate, I said out loud to the salesman and my wife "it has a vibration." Thinking it was just an unbalanced tire, I went ahead and purchased the truck. Now, the dealer has force balanced all the tires, which did not solve the problem. The service manager has agreed that there is a vibration, but he and a technician drove other trucks of the same configuration under the same circumstances - about 65 to 72 mph - and they all had the same vibration. I am not happy with Chevrolet...These vehicles are advertised as being quiet and so forth...not so. I am not a happy camper. I won't be able to speak again with the dealer until next week. A poor vehicle. I will pursue my options now, with the things I've seen here.
