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. All passengers were hospitalized but no other vehicles or people were hurt from the accident. My concern is regarding the periodic engine surge and/or jolting and lack of brake control. This is a safety hazard that must be addressed in order to avoid future incidents. We were very lucky to have not been killed in this auto accident.
