2017 KIA OPTIMA HYBRID Power Train Problems

The contact owns a 2017 Kia Optima. The contact stated that while his daughter was driving 70 MPH, the vehicle stalled. The vehicle was steered to the side of the road. The vehicle was towed to a dealer where it was diagnosed and determined that the engine needed to be replaced. The vehicle was repaired but failed to accelerate as intended or change gear as intended. The vehicle was then taken to another dealer where it was diagnosed that the triaxle needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 140,000.

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.
