general problems of the 2011 Lexus RX350

As I was trying to park my vehicle, it accelerated and hit a building then went backwards. I managed to keep the car from reversing into the street but the brakes did not work and car did not slow down. It hit the building a second time. I put the car in park and it stopped. None of the airbags inflated and the car was totaled. Toyota took no blame for the accident and I'm left without a vehicle. This car is in a group of recalled cars, Lexus does not have records of ever recalling this truck.

I want to know if my car's air bags are safe. I recently was told many older Lexus SUV's had dangerous air bags and the car owners were able to receive safe cars from Lexus.

I have contacted Lexus multiple times and they say they don't have parts to fix airbag.
