MY VEHICLE HAS HAD MULTIPLE ISSUES WITH ITS HYBRID BATTERY MANAGEMENT SYSTEM SINCE PURCHASE. IT HAS BEEN TOWED 4 TIMES. WHILE DRIVING MY CAR WILL START TO JERK AND A WARNING SYSTEM TELLING ME THERE IS A PROBLEM WITH THE BATTERY MANAGEMENT SYSTEM (BMS) AND THE POWER TRAIN. IT WILL TELL ME TO PULL OVER OR TO CONTACT THE SERVICE DEPARTMENT. THIS CAR HAS HAD ITS BATTERY REPLACED AND SOFTWARE UPGRADED NUMEROUS TIMES, BUT I KEEP HAVING THE SAME ISSUE. I'M CONCERNED THE BATTERY SYSTEM IS FAULTY AND IT'S DANGEROUS TO DRIVE AT THIS POINT, AS NOTHING PRECEEDS THE ISSUES - THEY HAPPEN OUT OF NOWHERE.
