Mid/rear Seats Assembly problems of the 2003 Toyota 4Runner

I was stopped on the highway behind a truck making a left turn when I was rear ended by another truck going 60 mph. My 4runner was crushed between them, totalled, and my air bags never deployed. I hit the steering wheel so hard I bounced off of it and broke my seat from the momentum. When I awoke I had slid into the back seat (which is all that was really left of the vehicle). Although I am thankful to be alive, I feel that at that force, the airbags should have deployed!.

Consumer stated rear seats did not lock in place. As a result, when applying brakes suddenly the seats came up.

The rear seat back rest on passenger side squeaks and makes a rattling noise. If the back rest is folded down the noise goes away. It seems to be the locking mechanism. Based on research on the internet, this seems to be a common problem. Dealer offered to look at it.
