2019 AUDI A7 Forward Collision Avoidance Automatic Emergency Braking Problems

The car now has come to an emergency stop twice on two separate occasion's here in Columbia and in Atlanta while I am attempting to cross an intersection or leaving a median lane. The cars safety features stop working at random times and throw several warning signs. Car has lost power while attempting to drive forward and rolls back with an initiates rear view camera. I have taken my vehicle to the Audi Dealership several times over the last year and the problems continue. The customer service has been poor and this car is supposed to be certified and i have had nothing but problems. The steering sometimes pulls you into other lanes and makes mistakes on changing speeds while using cruise control and slows car down tremendously.
