2017 Audi Q7 steering problems

1. Driving 2017 audi q7 (mileage 17017) on I-85 close to the richmond, va. Dry, straight and no traffic road. 2. Both hands keep on steel wheel, car lost control, lane keep did not work, tried used the steel wheel to adjust, the steel wheel over response. 3. The car went to left and right, rollover, and crash. 4.

While driving down a local city street, the car began to lose power, flashed a bunch of error codes and then lost power within a few seconds. The steering wheel locked when this happened so the car could not safely be steered off the road. They did initially replace the battery thinking that that was the cause but it happened shortly after leaving the mechanic so it we took at back which is when we were told that a software update was needed but that only the dealership can do this.
