1997 TOYOTA 4RUNNER Electronic Stability Control Esc Problems

I OWN A 1997 4RUNNER. DURING MY DRIVING THE VEHICLE FEW WEEKS AGO, THE CHASSIS LOCATED ON THE REAR PASSENGER SIDE SPLIT APART AND ALMOST RESULTED IN A FATAL ACCIDENT WITH MY FAMILY. THIS FAILURE, HOWEVER, IS PURELY AN ENGINEERING DESIGN AND MANUFACTURING FAILURES.HENCE, THE VEHICLE HAS BECOME UN-DRIVABLE. WHEN I CONTACTED TOYOTA AND ITS DEALERSHIPS, THEY SAID TO REPAIR THE VEHICLE WILL COST ME $8,100.00. HENCE, I FEEL THAT, IN COMPARISON TO OTHER VEHICLES FROM DIFFERENT BRAND OF CARS COMPANIES, THEREWITH, WHEREBY, THEY ARE STILL ON SOME PART OF THE WORLD, ARE STILL DRIVABLE AND USEFUL. HOWEVER, FOR THE KIND OF MONEY SPENT ON THE PURCHASE, THE REQUIRED MAINTENANCE, THE VEHICLE IS THAT OLD THEY ARE LIABLE FOR A FIFTEEN YEAR OLD VEHICLE. *TR

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. *TR
