Scion IQ Acceleration problems by year

have a 2013 Scion IQ (auto/cvt). I had the 'check engine' and 'trac control' lights come on a few years ago.. I was driving on city streets. All I noticed was that the car didn't respond as it should when I gave it gas. ( nothing drastic ) I ran the codes. It said the gas pedal was the problem. I removed the pedal assembly. (it's easier to unplug it that way. I unplugged it and looked at the inside of the plug. All looked fine. Plugged the pedal back in and all was good then. (I'm sure I avoided a $500 bill...

I got into 2 accidents in 3 days while parking into or out of a parking space. The first accident 07/04/2020, my car was parked in a parking lot. I placed the car in reverse and suddenly it accelerated and the brakes failed to work. My vehicle only stopped after crashing into the car behind me. The second accident happen 7/7/2020 while pulling forward into a parking space, the car suddenly accelerated and brakes failed to work again. I crashed into a cement pole which stopped my vehicle. I couldn't figure out...

On aug 16, 2018 @ 6:30 am while exiting at the garage in my apt heading to work; I started the engine of my car and it was okey. I started to drive on the ramp on the drive way the engine stops. I reversed/ back up and started the engine again, while on the ramp again it accelerated and never stop though brake was applied. The car won't stop; so I decided to crashed my car at the car park on the side street, before I reach to the traffic lane and might cause a fatal accident. I damaged my car on the driver side as well as the car I crashed on/ the bumper, headlight & fender were visibly damaged.
