I park in a 5 level parking garage. Several months ago, I was leaving when I came up to the ramp to the next lower level. I let off on the accelerator before I went from flat to lowering ramp. The truck shifted up to second gear, accelerated and through me toward the vehicle in front. The truck went out of my control. If I were not a safe driver I would have struck the vehicle. This issue has occurred another time as well. There have been other problems which are numerous. I will address them individual in further complaints.

While driving at speeds starting at and above 70 MPH there is an audible noise not present at any other time or circumstance. This is also felt thru the gas petal so my concern is that there could possibly be a defect or out-of-balance component. I demonstrated this condition with the dealer's technician on this and another identical 1500 and it had the same issue. Discussing this with another 2015 silverado 1500 owner found that their vehicle also has the same condition. In fact their vehicle when operated at speeds above 70 MPH vibrates so noticeably that the cup holders spill the contents.
My silverado has developed a vibration around 4-5000 miles from new. The vibration starts around 60mph and increases in intensity up to and beyond 80mph, the legal speed limit in texas. The vibration can be felt throughout the cabin in the seats, center console, steering wheel, doors and gas pedal. On my last 3+ hour drive I had to stop midway because the vibrations gave me a headache. That's never happened in any other vehicle ever. After 3 visits to the dealer and multiple road force balance and tire replacements later the dealer states the truck is operating normal and is in spec. This is unacceptable for a brand new vehicle and I'm working on taking it to the next level with gm to deal with the problem.
