Speed Control Linkage problems of the 2014 Chevrolet Silverado

While moving from a stop the truck sometimes lags in acceleration which may cause the operator to depress the accelerator further than required to enter traffic. This condition also may cause a short acceleration delay when pulling into traffic that can be unexpected by the operator. I have been surprised many times by this operator disconnect accelerating from a stationary position. After driving my new truck 900 miles I investigated the accelerator pedal assembly bracket to find that the entire bracket is not properly fastened structurally to the fire wall by design. I inspected my truck on 12/23/14 and found this problem, the accelerator pedal bracket flex on my truck looks to be ~3/4" to 1" before the electronic linkage engages. The pedal tip-in engagement has to flex the mounting bracket before the electronic acceleration switch engages. I can't believe the gm engineering and design team's would approve of such a flimsy mounting bracket for this important part of basic motor vehicle operation. I feel over time and usage that this bracket may completely fail as currently designed. I could shim and install additional hardware to correct this safety issue, but I feel this design issue should be addressed with gm before someone has a crash or worst.
