Open the full vehicle complaint log (all categories)I was driving down a one lane road in my car that is less than a month old, when all of a sudden my car aggressively veered to the right over the shoulder line, then it veered to the left over the yellow line and then the right again and it kept going over the line down a slight embankment into the woods about 30 feet. All the while the steering and brakes completely failed and would not work and the car was beeping. The only thing that stopped me was hitting a boulder. I kept trying to brake. My foot was pressed all the way down to the floor and it would not stop. It was terrifying. There was a witness who told me I must have had angels watching over me as I was not injured nor was anyone else. If anyone was driving in the opposite direction I could have hit them head on. If I was on a two lane or more road or on a bridge or a highway, it could have been tragic. Clearly there is a mechanical or electrical defect. The car was completely out of my control. Audi of America obtained the data recorder and investigated. They have not found any defects and deny responsibility. This is impossible. The brakes and steering did not work and the car was swerving for no reason. Even the witness attested to this.
