Cruise Control problems of the 2017 Audi Q7

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. Had sent car in dealership two times to repairing auto brake problems (this car did not stop but speed up even front car very close, I need use brake to prevent forward collision multiple times), still did not fixed, went on 7/8/2017 without appointment, dealer schedule full. 6. One time to repairing safety surround-view exterior camera. Three time recalls repair. 7. Car had multiple time error messages in 17 months, such as adaptive cruise control unavailable, Audi pre-sense currently restricted. 8. Car add on multiple safety features, Q7 premium plus with enhanced safety features driver assistance package (adaptive cruise control, Audi active lane assist, high-beam assistant, improved forward collision mitigation system, Audi pre-sense). 9. Vision package (Audi virtual cockpit, full led headlights, surround-view camera, pedestrian detection, night vision, rear cross-traffic detection, blind spot detection, traffic sign recognition). 10. We added the enhanced safety features in Audi Q7, but just one year and five months, in the straight and dry road, no traffic and no reason, still in warranty period, car crashed, and total lose. The car has more safety features than any my other cars but provides much less safety, my wife and I almost lose our life.
