Car Accelerates On Its Own problems of the 2018 Mazda CX-5

On January 10, 2019, I slowed down in my local grocery store parking lot, going about 10 miles and hour, and was coasting into a parking space at about 5 mph. It was about 1:15 pm on a sunny, clear day. I was applying the brake to stop the car as I pulled into the spot yet I was going slow and coasting straight into the spot. Suddenly, the car sped up, the brakes had no response, and the car accelerated hitting 3 parked cars near the parking space. I did not have my foot on the accelerator, I had my foot on the brake. . . But more than anything, I had no control, it was unintended acceleration. Then the car stopped after I hit three vehicles and fortunately no humans. I was shaken, but no bags deployed. I have approximately 6950 miles on this car. I have been the only owner. I am afraid to drive this car because I am concerned it will do this again and I will be in traffic or near people and I could hurt or kill myself or someone else. There was no warning of any problem. I don't want to update my documents on the internet but will submit once I have an NHTSA employee reach out to me. My records include a filed police report, a report with Mazda corporate (as of today) and pictures of the vehicles which are available upon request.
