When either accelerating from a stop or while actively traveling at speed the vehicle will drop speed and shake to the point that you believe you may lose control of the vehicle and/or you may get rear-ended or hit by another vehicle. It has happened while turning from a stopped position onto the main road and I was almost killed by being struck by a vehicle when the vehicle would not accelerate. The second major incident was when I was traveling at 70 mph on the expressway, the vehicle suddenly decelerated, the steering wheel began shaking and the car was almost unable to be controlled. The freeway incident took place 6/6/2020

This issue applies to when the vehicle is in motion. The brake pedal height is set too high off the floor compared to the accelerator pedal. When driving a car you should be able to comfortably pivot between gas and brake pedals while keeping your heel on the floor. With the brake pedal set so high on this car, I have to completely take my foot off the floor and move my whole foot over to apply the brake when switching from the accelerator to the brake pedal. Also, because of the pedal height, my foot gets caught on the pedal causing a delay in applying the brake. Also happens when going from the brake pedal to the gas pedal- the foot catches the edge of the brake pedal and unintentionally applies the brake when trying to apply the gas. The Chevrolet dealership stated the brake pedal height cannot be adjusted. I believe this is a safety issue and needs to he addressed.

I backed out of my icy driveway and onto the clear, dry road. Set my cruise control to 48mph and after about 30 seconds, my traction control and service engine lights came on with an error message that said "service stabilitrak" and my cruise control turned off. I closed the stabilitrak message, the traction control light turned off after about 30 seconds, and the service engine light turned off shortly after. But my cruise control still wont engage. I've turned the vehicle off and on and it still isnt working. It seems that a lot of different GM vehicles have experienced this problem, and the dealership has fixed it in several different ways. I read on a forum that someone had the issue and the GM dealership said there was an issue with the amount of ethanol in the gasoline. I happened to have filled up my tank the night before with regular unleaded from my local speedway. Not sure of that could have been connected.
