IT WAS A COLD DAY IN MASSACHUSETTS. I WARMED UP THE CAR IN THE MORNING FOR 10 MINUTES BEFORE STARTING TO DRIVE TO WORK. I GOT ONTO THE MASSACHUSETTS PIKE AND AFTER A COUPLE EXITS OF CRUISING AT 60 HIT STOP AND GO TRAFFIC. AT ONE OF THE ENTRANCES AND WHEN I SLOWED DOWN TO A STOP IN THE TRAFFIC MY CAR FLASHED THE BATTERY CRITICAL CHARGING ERROR FOR A SPLIT SECOND BEFORE SAYING EVERYTHING NEEDED TO BE RESTARTED BY PUTTING THE CAR INTO PARK. AFTER THAT, THE CAR COMPLETELY SHUT DOWN. I WAS NOT ABLE TO PUT ON HAZARDS UNTIL ABOUT 15 SECONDS LATER OF TRYING TO GET THE POWER BACK ON DID THE CAR START UP. WITHIN THAT TIME A DRIVER BEHIND ME DECIDED TO HIT ME IN THE REAR. ON RESTART THE CAR DIDN'T SHOW THE FAULT BUT UPON LOOKING UP THE BATTERY CRITICAL CHARGING FAILURE IT STATES TO NOT DRIVE THE CAR AND TO IMMEDIATELY TAKE IT TO A SHOP. THE SHOP CANNOT FIND THE CODE DUE TO IT BEING WIPED MAKING SOLVING THE ISSUE EVEN MORE DIFFICULT.
