Safety System Malfunction message appears on dash. Passenger side air bag goes on and off while driving. Whole system chimes and random messages flashing on screen constantly. At times system doesn’t recognize that I have my drivers side seatbelt buckled. So system keeps chiming cars Stanton. Random messages flash on dash. Traffic jam assist (3 cars symbol) unavailable and image flash on dash and does another chime. Vehicle has given random warning beeps when reversing 2 times since these issues started and has done automatic breaking both times as I was trying to reverse. Issues happen randomly and started about 300 miles ago (2 weeks or so) seem to be getting more frequent in past few days. I was trying to check today for open recall and was surprised to not have any for this issue / vehicle. I have not yet called the dealership but plan on doing so this week. This “Safety System Malfunction” and all the chimes, flashes, beeps, screen messages and the automatic vehicle responses is VERY dangerous!!

While driving, the power steering completely went out and lost the ability to steer, while on the road. There were no prior warnings or feeling in the steering to present a possible future failure of steering under power. Put myself, my wife and the other operators at risk as I lost all power steering and had to pull over immediately. I have a current repair order open at a local shop and the PSM module has failed, of course requiring a full steering rack replacement to the tune of +$5k.

While driving, the steering wheel suddenly locked up and could not be turned. Several warning lights simultaneously appeared on the dashboard including: "Steering malfunction! Please stop vehicle", "Audi adaptive light malfunction! See owners manual", "Start/stop system malfunction! Function unavailable", and "Audi pre sense currently limited" - No warning lights were present prior to this event. The sudden loss of steering could have caused serious injury to myself and to other drivers or pedestrians nearby. I was thankfully able to stop the vehicle, but I could not pull over because the steering wheel could not be turned. The car was towed to the Audi dealership and I was told the "Electronic power steering rack" would need to be replaced costing nearly $5,000.00.

This was unintentional acceleration case: When I got into the parking space, the car was almost stopped and I was about to press the park button (gear) and the car suddenly accelerated and in a fraction of a second, climbed the curb, crashed into the fence, broke the fence and crushed on a tree. I was still applying brake to stop it and I could not do anything else. The following facts show that the acceleration was totally out of my control. 1.vehicle climbed the curb 2. and climbed the dirt part, shrubs 3. to hit the fence and broke it; It looked like something mall functioned. As a matter of fact, no safety feature worked and no sound signals went on ! Even vehicle's collision system did not kick in when car was climbing over the curb. Fortunately, I could get out of that car and my body was aching due to the seat belt and airbag explosion. (Driver side bag exploded for sure. I do not remember if the other side bag exploded.)
