I was leaving out of the parking lot of the shops Santa Anita. I was parked underneath by [XXX] and proceeded to to leave and turn out right towards the wide open parking lot. At the time I was leaving, it was completely empty. This parking lot is wide open as I was leaving and Iam going no more than 15 mph when suddenly a beeping sound goes off and the car slams on its brakes on its own! I didnat even have enough time to stop on my own and look to see what the alert sound was. The car stop and jerked me so hard and slammed forward so hard. Thankfully I was in an empty open parking lot. That would have cause a very bad car accident and I would have been badly hurt and the car that would have slammed into me from behind! This has left me with so much anxiety and I am now very scared to drive this car at all even. I havenat even had this car for a year and this is the second time Iave had an issue with it. And I tried explaining to the dealership that for the past couple weeks to month that when I drive the car, it has this pulling feeling when Iam coasting. It has never felt that way before. This is supposed to be a new car. It doesnat even have 15,000 miles on it yet! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
