Beginning at 1,700 miles (happened three times), then again just two days ago at 4,700 miles, just after starting the car, the electronic waning messages and lights on dash went crazy. The following messages appeared in a rotating sequence (1) safety system malfunction (2) tire pressure malfunction (3) transmission malfunction (4) drive system malfunction (5) adaptive light malfunction (6) brakes malfunction - stop vehicle safely (7) Audi pre sense currently limited (8) stabilization control ESC malfunction. In addition, the power steering stopped working for 5-10 seconds while attempting to drive at low speed. The messages appeared first while stationary, but continued while driving at low and highway speeds. Each time, over the course of 24 hours, the warnings lights and messages went back to normal.

Vehicle stability while driving on automatic driving /lane keeping system failed 3 times almost causing vehicle to loose control and crash. On 4 other occasions the vehicles lane keeping failed to keep between lanes and instead vear vehicle in different steering directions, forcing me to pull against the stearing wheel to go back straight. Audi America and local dealer continue to say everything is ok but on all three occasions I had witnesses in my car.

I was going approximately 55 miles per hour in the center lane on the interstate. Shortly after shifting the car into sport mode, the vehicie had sequential malfunction notifications appear on my screen. The specific order is difficult to remember due to the rapidness of the whole situation. The malfunctions appearing on the screen over the steering wheel were: Traction control malfunction, TPMS (tire pressure monitoring system malfunction, parking brake malfunction, automatic start/stop system: Malfunction, start/stop system: Malfunction, and a drive system: Malfunction. The majority of these warnings said to please contact service. While the malfunctions appeared the engine of my car stopped working, acceleration stopped working, and the engine did not maintain the current speed. The vehicle essentially died at highway speed while I was travelling in the middle lane. I turned on my hazard lights and was able to coast to the shoulder (after other drivers allowed me over). Once stopped I turned off the car, pressed the start/stop button which resulted in a repeat of the start/stop malfunction indicator, and it instructed me to 'manually start'. I then pressed the button off and back on again, the car then restarted. The car shifted into drive and I took it immediately to the local Audi dealership.
