I got jump start and when i plugged in high voltage charger for high voltage battery i was able to start the car and let the engine run. But the moment i unplugged, car doesn't turn on and i got bunch of error messages like, " Hybrid System Malfunction", "High Voltage System Fault" "Check Engine light is also On" ... but it looks like high voltage battery is not charging, bec after that one time start now i get msg, "Unable to charge" ... any suggestions? I might have just ran out of warranty. Plz advise to text asap.
