Of course they were supposed to deploy. Who told you they weren't? Correct me if I'm wrong, but I assume you bought this car used, and probably not from Lexus. In all likelihood, it was in an accident at one time where the airbags deployed, and they were either never replaced, or never properly replaced. Another alternative would be a car which had experienced flooding which again either caused deployment, or screwed up the sensors. However, in all cases your warning lights should alert you to airbag issues, unless someone has tampered with them. If, in fact, you didn't buy the car from Lexus, then first talk to Lexus for more info. In either case, you'll end up talking to an attorney, because "something is rotten in Denmark."
No the car was bought brand new from the lexus dealership, never been in an accident, no flooding the car WAS in great condition. I understand that in certain circumstances that airbags can be more harmful, but if thats the way im told to look at airbags than why are they considered a safety feature if they can cause me more harm than the accident? It just makes no sense... and the GM at the dealership told me that i should just be happy that i walked away with minor injuries, and that that alone should show me the car did what it was supposed to... and that i should NOT want them to deploy! im not sure at what force i have to head on hit something before my safety features kick in?! this alone makes me not want to own a Lexus!! and i loved my car!
