Looking for advice. Bought my silverado June 27, 2014. After the first day noticed the shaking/vibration in steering wheel and accelerator pedal. Googled the issue and came upon this forum. I have been following it ever since. My truck now has 1400 miles and has been in the shop twice. 1st service consisted of them saying that two of the Goodyear SRA's were out of round and were replaced. This did not fix the problem. 2nd service consisted of them changing a 3rd tire and replacing all four shocks. This dampened the vibration in the steering wheel considerably, but I am still feeling the shaking in the pedal, center console and other interior parts. The service manager advised me that the second try fixed all issues and that if I was not happy then they were advised to involve the District Manager. I called yesterday to bring it in for another attempt at fixing the vehicle and was told that they would need to contact the district manager before any further work done to the vehicle. After not hearing anything in 24 hours i called back and was advised that they still do not have an answer for me because the district manager is now talking to GM about "what the next plan of action is". Very unhappy with the truck and it seems that they know there is a problem and I am about to get told there is nothing else they can do. 2014 Silverado, crew cab 4x4 LT w/ 5.3 and 3.42 gears.
