Engine Belts And Pulleys problems of the 2009 Chevrolet Impala

I crashed heading down a hill . I crashed into a telephone pole after my car suddenly revved up,gained speed as I headed towards a telephone pole ,with loss of power steering ,brakes because my car quit after gaining speed due to the rpms amping up on their own and going down a hill. When I hit the pole,the telephone lines snapped and I was trapped in the car because they landed on my driver window and were shooting out sparks as if they were roman candles and a fire started on the right side of my car in some pine straw. When the firemen was able to get me out of the car he came to the passenger side and by then I had taken my seat belt off and the fireman advised me to get out of the passenger side if I was able and I told him that I was scared to let off the brake because I thought for some reason being out of my head that the car was going to roll if I let off the brake and he took his hand and slammed the car up in to park because I didn't even realize I had not put it in park. He said you can let your foot off the brake because it will not roll and I said I'm too scared . I asked. . Can I put the emergency brake on and he said yes and when I did it went straight to the floor. Then I continued to come out the passenger side and hop to the sidewalk with my feet together just in case anything was hot and to keep from getting electrocutied just in case something was still hot around us. When I was struck by the airbag the and the seat belt did its job I suppose but for some reason my neck was yanked so hard that it hurts so badd everyday when I didn't go to the hospital. I was unaware of any recalls when I purchased from a dealership on Jan 18 2020. The day before I crashed we were traveling uphill &I had a friend with me that helped grab the wheel until it stopped after it revved up & quit. I attempted to crank it 3xs with success. I was stunned as to why it did it .

I was driving to work on the freeway then I noticed that my car's rpm started bouncing up and down from two and a half to two and back and forth and then my check engine light turns on and says engine power is reduced and as well as the service traction light turns on. I see that I have to press on the gas pedal a lot more further down for my car to stay at 60 mph and after 2 minutes of this my car's rpm drops to 0. My car turns off with the car reading starter disabled and service throttle. I had to pull to the shoulder. This incident had made me late for work and this incident happens a lot now. This can happen from once every two or three weeks to twice a week. Just recently my car's seat belts will become undone without anyone clicking the button for it to release. Also recently my service airbags light has came on.
