2015 AUDI A8 Electrical System Problems

So I purchased a vehicle from wright drive in El Paso, Texas. I was driving home back to Alamogordo which is 90 miles away, maybe 80 I realized there was no adaptive cruise control. So I messaged dealership. They told me that there was nothing they could do. It's not a safety issue. I got the vehicle home the next day. I found out the whole front suspension was bad. I kept hearing a noise when I would drive over bumps and it was really loud. I contacted the dealership, told them that the suspension was bad. They told me to take it to Audi to have them look at it. It came out to like $8,000 worth of repairs. They told me they would not pay that and I could return the vehicle for a full refund. I told them okay. I would be there in 3 days because...

I WAS DRIVING ON A SUBURBAN CITY STREET IN A STRAIGHT LINE WITH NO CARS OR ANY OTHER OBSTRUCTIONS AHEAD OF ME OR BEHIND ME. WITHOUT WARNING, THE CAR ENGAGED ITS EMERGENCY BRAKING THROWING MY DAUGHTER AND ME FORWARD VIOLENTLY INTO OUR SEAT BELTS. WHEN I FELL BACK, THE DASHBOARD WAS SHOWING ME A PROXIMITY WARNING BUT AGAIN NOTHING WAS ANYWHERE NEAR OUR CAR. THE SERVICING DEALER SAID THEY DIDN'T FIND ANY ERROR CODES AND SO THERE WAS NOTHING THEY COULD DO. THIS HASN'T HAPPENED AGAIN (YET) BUT THE CAMERAS ALL AROUND THE CAR THAT ENGAGE FOR PARKING AND IN REVERSE ARE CONSTANTLY GOING OUT AND/OR THE VEHICLE MMI SYSTEM RANDOMLY RETRACTS INTO THE DASH WHILE DRIVING.

TL* THE CONTACT OWNS A 2015 AUDI A8. THE CONTACT STATED THAT WHILE DRIVING AT APPROXIMATELY 60 MPH, THE VEHICLE SPEED DECREASED AND SUDDENLY FAILED TO GO OVER 40 MPH. IN ADDITION, WHEN DEPRESSING THE ACCELERATOR PEDAL, THE VEHICLE STALLED. THE FAILURE OCCURRED INTERMITTENTLY. THE VEHICLE WAS TAKEN TO THE DEALER BUT THE FAILURE COULD NOT BE DUPLICATED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 10,427.
