Prior to purchase of the vehicle a vibration and bouncing was noted on the test drive, the dealer assured me that the problem would be corrected and two days later they replaced the tires. This did not eliminate all of the bouncing, the dealer again serviced the vehicle, the salesman and the service manager both rode with me in the vehicle and agreed that there was a problem and that it would be corrected even if all of the suspension components, wheels and tires had to be replaced. One day later I was told that the bouncing was characteristic of the vehicle and that there was nothing they could do about it, no other solution was offered. I do not feel the vehicle is performing correctly and is not safe.

I currently own a 2004 Chevrolet Silverado 1500 series truck, prior to signing the papers there was a shimmy/vibration coming from the rear of the vehicle. The dealership said that the tires were not properly spun balanced, stating that they were I signed the papers, then after that the vehicle had the drive shaft replaced, two sets of tires, alignment out, calipers hanging up-replaced, rear disc parking brake both replaced, then after the shimmy vibration continued, GM technical assistance to the dealership stated that all the 2004 Chevrolet Silverado 1500 series have this vibration and it is classified as "beam shake". their solution was to put 200 pounds of weight over the axle in the bed of the truck stating "it will ride like a Cadillac". the weight did not change the vibration and now they have a GM field engineer coming to look at the truck. The vehicle was purchased 12 Dec. 2003 and still has this vibration to date, all the time above 50 M.P.H. GM customer service claim number [xxx]. VIN # [xxx]. state farm insurance co. Was contacted. I believe that the vehicle is unsafe at high speeds. Wanted to file claim hopefully to avoid more severe problems. Have contacted legal advise referencing lemon law. Will file complaint with attorney generals office. Updated 07/30/2012 information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6)
