NHTSA Complaint #11559336 — 2018 AUDI S6

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.
