1997 Toyota 4RUNNER brakes problems

While driving on the highway at the speed limit (60 MPH), the vehicle surged/jolted forward pulling to the right. I was unable to regain control of vehicle causing me to merge into the direction of a tractor trailer. I tried to turn away from tractor trailer to avoid collision. My vehicle hit the rear tire of the tractor trailer and I began to swerve out of control. My brakes didn't seem to help either, they didn't function. This resulted in the vehicle rolling over 3+ times, the car was totaled.

The vehicle was taken to a private mechanic where it was found that the rear under body frame had fractured in half due to corrosion. The contact also stated that the fuel tank was also corroded. The vehicle was not repaired. The manufacturer was contacted about the failure but did not provide any assistance.
