On Friday 10/11 at 10:45 a.m I was in traffic on Day Street in Moreno Valley, California. This was the third time I experienced a sudden unintended acceleration with my Tesla. I would have hit the car in front of me, but I was able to swerve into an island on my left to avoid the car. The car went over the curve and stopped. I am unsure what happened but after my prior experiences, I knew how to react. Had I not reacted swiftly, I would have hit the car in front of me. There were no warning messages. I have an appointment with Tesla on Wed 10/26. When this happened the first time, they claimed there was nothing wrong with the car, but I think they are not looking hard enough. I am aware of a voltage problem that other Tesla owners have experienced that can lead to sudden unintended acceleration.
