NHTSA Complaint #10427106 — 2011 HYUNDAI SONATA

I DRIVE THE HYUNDAI SONATA HYBRID. THE FIRST TIME THE PROBLEM OCCURRED AT APPROX 9800 MILES, I WAS DRIVING 60 MPH ON A HIGHWAY WHEN THE VEHICLE LOST BATTERY POWER AND AN ALARM SOUNDED, AND THEN A SIGNAL INDICATING TO "CHECK CHARGING SYSTEM." I IMMEDIATELY TOOK THE VEHICLE TO MY HYUNDAI DEALERSHIP WHERE THEY WERE AWARE OF THE ISSUE, BUT DID NOT KNOW HOW TO FIX IT AND SUGGESTED I JUST SIMPLY TURN OFF AND THEN RESTART MY CAR. IT HAPPENED TWO ADDITIONAL TIMES, ONE WHILE APPROACHING A STOP LIGHT, AND ANOTHER TIME WHILE I WAS STOPPED AT A STOP LIGHT. THE LAST TIME IT HAPPENED, I COULD NOT GET MY VEHICLE TO RESET BY RESTARTING ONCE. I HAD TO SHUT THE VEHICLE OFF, THEN ATTEMPTED SEVERAL TIMES TO RESTART. THE 4TH TIME I TRIED TO START IT, I WAS ABLE TO DO SO SUCESSFULLY. I DID NOTICE THE LAST TIME IT HAPPENED, THE ENGINE LIGHT REMAINED ON EVEN AFTER BATTERY POWER WAS RESTORED. I AM TAKING IT BACK TO THE DEALERSHIP TOMORROW AND DEMANDING A SOLUTION. THIS IS JUST TOO DANGEROUS TO LOSE POWER IN HIGH-SPEED TRAFFIC, AND THE PROBLEM SEEMS TO BE OCCURING AT ALL SPEEDS. *TR
