Air Bag Not Deploy problems of the 2012 Lexus ES

Takata recall or takata issues - I was involved in an accident in my 2012 Lexus Es 350. I was hit from behind by another vehicle (2005 Jeep liberty) at about 45mph and my front airbags did not deploy. I read the owners manual which indicated that if hit from behind the front airbags do not deploy with the exception of front collisions. This is extremely dangerous and unsafe for all consumers because the force of the accident while the vehicle was in motion on a city street caused me and my husband as the passengers bodily harm. My head hit the steering wheel and his head hit the dashboard - concussions and lost consciousness. Had we been hit any harder it could have resulted in death. Also, had the Lexus been designed to deploy the front airbags deployed when hit from behind at a certain speed, it would have prevented us from hitting our heads on such hard surfaces. I am outrage and disappointed that such a luxury car could not keep us safe. Because of this experience I am hesitant about purchasing another Lexus or recommending that anyone else I know purchase a Lexus.
