2007 Toyota Camry fuel system problems

We bought 2007 camry in july of 2007. My wife drove it to work and got an accident on 12/5/07. When she exited highway, she used gas then used brake to reduce the speed. The brake did not work. The car sped out of control and hit the side of hill. The car was roll over to one side and totaled. My wife was badly injured and was sent to hospital emergency room.

I have an excessive engine oil consumption problem so on march 2016, I go to the dealer to check and said that my car pass the test without any suggestion to follow on, I still has this problem and even more serious so I go back to check then the dealer said once pass is not their issue ,I wonder what is the standard the pass or not pass and I call the main toyota office to ask for help and they said ,I can ask for the second test but I just pass their extended warranty that is just pass half a month ago.
