NHTSA Complaint #11337577 — 2013 HYUNDAI SONATA

BEGINNING AT AROUND 90K MILES, THERE WAS INTERMITTENT STUTTERING, ABOUT 2 SECONDS APART, WHEREBY THE VEHICLE WOULD LOSE POWER WHILE IN MOTION; AT VARIOUS SPEEDS, BOTH ON ACCELERATION AND DECELERATION OR COASTING. THE EPISODES WERE ONLY HAPPENING AFTER THE CAR HAD BEEN DRIVEN FOR MORE THAN AN HOUR. NOW, AT 92K MILES THE STUTTERING HAS INCREASED IN FREQUENCY AND TODAY I RECEIVED A "HYBRID SYSTEM WARNING! SAFELY STOP AND DO NOT DRIVE" MESSAGE WITH AUDIBLE WARNING CHIMES AND A "WRENCH" ICON ILLUMINATED. THIS TRIP WAS ONLY A TEN MILE TRIP, IN THE MORNING, OUTSIDE TEMPERATURE WAS ABOUT 65F. THE CAR HADN'T BEEN DRIVEN AT ALL THIS DAY PRIOR TO THIS EVENT. THE WARNINGS HAPPENED TWICE, LESS THAN ONE MILE TO MY HOME, AND I BARELY MADE IT TO MY DRIVEWAY, WHERE IT'S NOW PARKED.
