“On june 30th 2019 after leaving from work I was on my way to pier 1 which is approximately 2 miles away. I turned into the parking lot parked in front of pier 1 and all of a sudden my car accelerated out of control. It jumped the curb crashed through pier 1 window into the store and didn't stop until it hit a wall. At this time I'm in shock glass is every where and I could move I hear people in the background telling me to get out of the car but I was frozen from what just happened. I just want to hold Acura accountable because I see this has happened to several people”
