I was in motion and driving on a residential street, while operating vehicle at the time of accident. After the collision, the airbag did not deploy. The takata airbag was replaced by the auto manufacturer (Toyota dealership) prior to my above mentioned accident. The auto accident occurred for unknown reasons, possibly brake failure or unexpected acceleration of the car engine.
This is the second time within the last several weeks where I've had brake-line failure(also reported my first one here). My vehicle was just recently repaired under warranty at the dealership I bought it from for a catastrophic brake-line failure which nearly resulted in a major accident. After the repair to the exploded lines my dealer stated he inspected the remaining lines under the truck & said they all looked good & there shouldn't be anymore problems with the lines failing. That didn't happen however as I just had another line spring a sudden leak without any warning while driving to work. My vehicle is now off its warranty(only been 1500 miles since repair-79,000 miles on it now) so I cannot send it back to them. It wasn't a sudden, complete loss of brakes this time but a gradual softening of the brake pedal when trying to stop until all of the fluid was gone then I had next to nothing upon arrival to work. Anyhow, I did make it to work & then put more fluid in it to get it home when I got off shift. Upon searching for the leak I was surprised to notice that the lines had broken where there was no rusting involved, it turns out there's a mounting bracket which once had a grommet in it that either fell out or rotted away causing the bracket to cut through the lines under it from metal-to-metal contact. The lines involved looked as though they'd been cut with a knife at the location. The dealer never would've noticed this as it took me almost 30 minutes to find it myself. I did contact Toyota however they choose to do nothing about this however since I've had two sudden brake failures within 4,500 miles I feel I should let someone know before someone else gets the same problem and kills themselves or others when their brakes decide to fail without warning! thank-you!.
