First off let me start by saying the vehicle has 45k miles on it. There were no fault codes or system errors prior to the issue that developed. I was driving to a meeting in heavy rain, no issues or suspicion of issues arising. I parked the car, returned about 2 hours later started the car to find 6 warnings on the dash (tpms fault, acc disabled, steering disabled, air ride control disabled esc disabled and a few more. Notably was the steering, it had a red light and the steering wheel was very hard to turn. The vehicle couldnt be driven. After having the computer scanned the issue was the electronic steering rack. See codes below. This is very unfortunate and strange that it came out of nowhere especially to fail this way. The vehicle is available for inspection until the part is replaced.

I OWN A 2018 AUDI S6 WHICH I BEGAN DRIVING IN MARCH 2018. SINCE THEN THE WINDSHIELD HAS SHATTERED THREE TIMES, DUE TO ONLY MINOR IMPACTS OF ROCKS OR ROAD DEBRIS EACH TIME. THIS HAPPENED MOST RECENTLY A FEW WEEKS AGO WHILE DRIVING ON THE HIGHWAY AT ABOUT 70 MPH. I HAVE BEEN DRIVING FOR 36 YEARS IN SEVEN DIFFERENT AUTOMOBILES AND I HAVE NEVER HAD TO HAVE A WINDSHIELD REPLACED. I ALSO DO MUCH LESS HIGHWAY DRIVING THAN I HAVE IN THE PAST. THE FACT THAT THE WINDSHIELD ON MY AUDI HAS SHATTERED THREE TIMES IN THREE YEARS CANNOT POSSIBLY BE JUST BAD LUCK. FORTUNATELY, EACH TIME THE WINDSHIELD SHATTERED IT WAS NOT IN THE DRIVER'S LINE OF SIGHT. IF THE WINDSHIELD HAD SHATTERED DIRECTLY IN FRONT OF THE DRIVER IT COULD HAVE CAUSED LOSS OF CONTROL OF THE VEHICLE. I FEEL THAT THIS IS A SIGNIFICANT SAFETY ISSUE AS THE WINDSHIELD ON THIS PARTICULAR AUDI MODEL SEEMS TO BE QUITE FRAGILE. I HAD PREVIOUSLY DRIVEN A 2009 AUDI A5 FOR NINE YEARS WITH NO SUCH ISSUES. I HAVE CONTACTED AUDI OF AMERICA WITH MY C

THE VEHICLE WAS DELIVERED TO AUDI SERVICE DEPARTMENT AND IT WAS DETERMINED THAT THE STEERING ANGLE SENSOR WAS MALFUNCTIONING; WHICH IS DIRECTLY LINKED TO STEERING SYSTEM FAULT. THE VEHICLE WAS DELIVERED TO ME BY A MEMBER OF THE SALES TEAM ON 11/30/2017 STATING THE VEHICLE WAS REPAIRED AND CLEAR OF ANY ISSUES. HOWEVER, THE STEERING SYSTEM FAULT RETURNED WITHIN HOURS AFTER THE DELIVERY WHILE DRIVING WESTBOUND ON I-565 AND THE ACTIVE LANE ASSISTANCE ENGAGED MAKING IT DIFFICULT TO STEER THE VEHICLE. I WAS ABLE TO DISENGAGE THE ACTIVE LANE ASSISTANCE, HOWEVER THE VEHICLE STEERING BECAME INCREASINGLY MORE DIFFICULT TO STEER. AFTER PICKING UP MY CHILDREN FORM SCHOOL, THE VE
