On 2/21/23, at 1245, I hit the rear bumper of my 2021 Cadillac Escalade when I backed up after I had scraped the driver side of my door panel as I drive thru a gated parking area. I started driving forward, turned left onto the back row of parking area. Suddenly the car accelerated very fast like from 0-60 mph. I quickly tried to step on the brake but the car kept accelerating. I tried to steer the steering wheel away from a parked car that it was headed directly for. The steering wheel locked & wouldnât turn. The car proceeded to hit a Hyundai. It knocked the Hyundai out of its way & continued to surge forward where it hit another parked dodge ram double cab truck. Thatâs when the Cadillac stopped. The air bag partially deployed just slightly past the steering wheel. I had absolutely no control of the car.
