I was turning into a parking spot when my brakes suddenly felt loose, as if they had lost hydraulic pressure, and my vehicle accelerated into a wall. I had my vehicle serviced 3 weeks ago, and my brakes were fine. The day before the incident, I was coming to a stop, and the car was lurching forward as I was trying to stop. This isn't the first time the issue has occurred, and I had previously mentioned it to the dealership, but they found nothing upon checking. I was going to take it into the dealership, but I got into the accident.
