On February 14, 2023 around 3:30 - 4:30 p.m. (EST), I drove to the local WAWA. Upon entering the driveway of WAWA at a very low speed and depressing the brake the car failed to come to a complete stop. I pressed down on the brake as hard as I good, but the car did not come to a stop until hitting the security/safety bollard in front of the WAWA store. I did not get injured and no one else was injured. The front end of my car sustained over $4000 worth of damage. The insurance company repaired by car. I was asked by the insurance company what caused the front end damage. As I played the accident over and over in my head, I just could not see what I did wrong. My foot was on the brake. Also, I entered the entrance of WAWA at a very slow/low speed. After a few weeks I took the car to the Mazda dealer to let them know the car accelerates and engine revs. Also, the car jolts forward while decelerating from about 20mph to 10mph. The car dealer/repair shop could not replicate the problem. Was told to bring the car back in, if problem continues.
