2020 Hyundai Santa FE fuel system problems

I parked my 2020 Hyundai Santa Fe in a hospital parking garage on the morning of July 30, 2024. I was getting ready to leave after my doctor’s appointment. I slowly reversed my car and hit a pillar behind me. As I put the car into drive to come forward slowly, the car accelerated forward at a very fast speed. I took my foot off of the gas and kept pressing the brake pedal, but the car kept speeding forward on its own and I crashed headfirst into a concrete wall.

I pulled into the driveway and put on the brakes when the vehicle accelerated and ran into the garage and the frame. There are tire marks on the cement showing the brakes were applied. I've had problems with the accelerate cutting out while on the freeway on ramp.
