2017 AUDI Q5 Unknown Or Other Problems

I was driving on the highway with no vehicles or overhead obstruction when the sunroof shattered.

HIT A STATIONARY HONDA CRV ON BLACK ICE AT APPROX 45-50 MPH. IMPACT WAS STRAIGHT ON FRONT OF OUR CAR AND REAR OF THE CRV. OUR BOTH VEHICLES WERE TOTALED, NONE OF OUR AIR BAGS DEPLOYED. OUR VEHICLE WAS THEN HIT FROM THE REAR BY A JEEP WRANGLER AT ABOUT THE SAME SPEED. STILL NO DEPLOYMENT OF AIR BAGS. WE ARE CONCERNED THAT THE AIRBAGS MAY HAVE BEEN DEFECTIVE. ACCIDENT HAPPENED IN A 31 CAR PILE UP ON I-68 NEAR EXIT 29. WE ARE VERY LUCKY THERE WERE NO KNOWN INJURIES OTHER THAN STIFFNESS AND SORE SPOTS. OCCUPANTS WERE DRIVER 52 YRS OLD AND FRONT PASSENGER 17 YRS OLD.

I AM CONCERNED ABOUT THE LACK OF VIABILITY OF THE DUE TO THE POSITIONING OF THE DRIVERS SIDE MIRROR IN THE AUDI A5 SUV. THE MIRROR IS VERY LARGE AND BLOCKS THE ABILITY TO SEE VEHICLES ON THE LEFT WHEN STOPPED AT A STOP SIGN, ESPECIALLY SML SPORTS CARS OR VEHICLES ON AN ANGLE IF THERE IS A SLIGHT HILL. SMALL PERSONS WILL BE MORE AFFECTED BY THIS THAN OTHERS. I HAVE HAD MANY CLOSE CALLS BECAUSE THE CAR WAS BEHIND THE MIRROR. ALSO THERE IS A BLIND SPOT WHEN USING THE VEHICLE DETECTION SYSTEM ON THE FREEWAY; IF THE APPROACHING VEHICLE IS HALF WAY PARALLEL TO YOU, IE CHANGED LANES CLOSE TO YOU, IT WILL NOT BE DETECTED BY THE SYSTEM, IT ONLY DETECTS VEHICLES APPROACHING A CAR LENGTH BEHIND. I THINK THIS IS A SIGNIFICANT PROBLEM AND SHOULD BE INVESTIGATED.
