I was making a left hand turn at an intersection with no cars in immediate proximity to my car and the emergency braking system activated violently causing the car to shut off. The pre sense light came on the dashboard. This happened 3 different times. I went to Freehold Audi and they stated the pre sense was doing its job. I reported this to Audi Headquarters last week and a report was written. Other electrical issues started happening, the lane change sensor was going off randomly, the windshield wipers were going off randomly. I traded the car in yesterday to Lexus of Eatontown. They said they were going to sell the Audi retail, I’m thinking to the auction. The car has less than 10,000 miles on it. I informed them about the issues I was having with the car but I’m worried they will sell it to someone without repairing the pre sense issue. I do not want anyone to get hurt in this vehicle. I hurt my neck and chest when the car violently stopped, so did my son. Someone could have easily rear ended me.
