I am requesting that dot NHTSA investigate the extreme wobble/vibration/shake on new 2017 Chevrolet Silverado 1500. The vehicle was purchased new and driven under 55 mph for the first 500 miles. After the first 500 miles and beginning to drive highway speeds, between 60 - 75+ miles per hour, a wobble/vibration/shake began to occur. When the wobble/vibration/shake begins the driver feels that control of the vehicle is being lost and the driver must decrease the speed, which is able to be accomplished with both releasing foot off of the accelerator or lightly breaking, in order to regain control. The vehicle has been to the dealer for front left wheel replacement due to the inability of original tire to be balanced, the vehicle has field force balancing 3 times, and the left front axle boot has been replaced. After several attempts to correct the wobble/vibration/shake, the vehicle now has ~10,000 miles, the wobble/vibration/shake continues to occur at highway speeds.
