When turning left in a busy intersection, our van was struck by another vehicle on the front passenger corner of the car. The strike occurred with my van going about 10 mph, the other car going about 45 mph. All of the airbags deployed. When the airbags deployed, the coverings on the lights came off and the small lightbulb and silver casing projected out, scratching my son's arm. Nothing in the vehicle should break or become a projectile when the airbags deploy. I am not certain on the last few questions.
TAKATA RECALL (?) WE PURCHASED THIS VAN ON 4/18/2019, PREVIOUSLY THE VAN WAS A RENTAL. THE NEXT EVENING, GOING TO DINNER ON A FRIDAY NIGHT ABOUT 9 P.M. I WAS ON A 2 LANE ROAD IN A RURAL AREA, TRAVELING AT 60 MPH AND A DOG WALKED IN FRONT OF ME. I HAD NO TIME TO REACT. THE FRONT END OF THE VAN WAS LAYING IN THE ROAD, NOT DRIVABLE. AGAIN, A FRONT END COLLISION AND NO AIR BAG DEPLOYMENT! 2ND TOYOTA SIENNA, FIRST A 2017 AND NOW A 2018, BOTH RENTAL SALES, BOTH HAD FRONT END COLLISIONS AND BOTH HAD NO AIR BAG DEPLOYMENT. AT 60 MPH THERE'S NO REASONABLE EXCUSE FOR NO AIR BAG DEPLOYMENT.
