I HIT A BEAR IN MONTANA IN MY 2017 MERCEDES C300 AT 86MPH AND DESTROYED THE FRONT OF MY CAR. THE SEATBELTS DEPLOYED AND WRENCHED US INTO OUR SEATS AND SMOKE CAME OUT OF THE FRONT AIR VENTS BUT THE AIRBAGS DID NOT GO OFF. ON THE DASH THE VEHICLES STATED THAT THE AIRBAGS IN ALL 4 ZONES IN THE CAR MALFUNCTIONED AND SERVICE IS REQUIRED. MERCEDES IS STATING THAT THE LIGHT IS FROM A SEATBELT ERROR CODE BUT THE DASH DID NOT SAY ANYTHING ABOUT SRS OR SEATBELTS. I DO NOT WANT TO PUT MY FAMILY BACK IN THE CAR AND DO NOT FEEL IT SHOULD BE REPAIRED. PLEASE SEE ATTACHED PHOTOS OF THE ERROR MESSAGES ON THE DASH. I DO NOT KNOW HOW I CAN HIT SOMETHING THAT HARD AND NOT HAVE THEM DEPLOY. MERCEDES IS DOING AN INTERNAL INVESTIGATION BUT THEY HAVE NOT GIVEN ME THE RESULTS OF THAT AND IT HAS BEEN OVER 3 WEEKS. VEHICLE WAS IN FOR A AIRBAG RECALL NOT TAKATA RELATED ON JANUARY OF 2018 AND THIS WAS SUPPOSED TO HAVE BEEN REPAIRED.
