I was operating the vehicle on 09/25/2021 and at approximately 9:45am, the car accelerated quickly causing me to lose control of the vehicle and crash into a guard rail. I was driving about 35-40 miles per hour and the vehicle took off out of no where and the car wouldn't brake. It was extremely frightful and I am lucky that the guard rail was in place, otherwise the vehicle would of flipped over or worse.
