WHILE SLOWLY MOVING DOWNHILL, ON THE FREEWAY, DURING RUSH HOUR TRAFFIC, I ATTEMPTED TO CHANGE LANES AND ACCELERATED QUICKLY.

PULLING INTO TRAFFIC THE CAR QUIT, LEAVING ME STARRING DOWN THE ONCOMING TRAFFIC. I WAS ABLE TO COAST TO THE SIDE AND GET IT RESTARTED. THIS HAPPENED TWICE DURING THE SAME DAY. IT WILL ALSO ONLY CHARGE THE BATTERIES TO 50%, AND SOMETIME THE CAR WON'T OPERATE ON ONLY BATTERY POWER.

MY 2012 HYUNDAI SONATA HYBRID LIMITED IS COMING UP WITH A WARNING SIGNAL "HYBRID SAFETY WARNING DO NOT DRIVE". THIS HAS HAPPENED ON THREE SEPARATE OCCASIONS.
