NHTSA Complaint #11363044 — 2013 HYUNDAI SONATA

I HAVE A 2013 HYUNDAI SONATA HYBRID WITH AUTOMATIC TRANSMISSION. MY SONATA AFTER DRIVING ABOUT AN HOUR OR SO LOOSES ACCELERATION POWER. WHEN I COME TO A STOP AT A LIGHT OR STOP SIGN IT DOES NOT WANT TO ACCELERATE. SOMETIMES THE RPMS WILL PEAK OUT IF I DEPRESS THE ACCELERATION PEDAL TO THE FLOOR BUT THE VEHICLE WILL STILL ONLY CRAWL OR MOVE VERY SLOWLY 2-3MPH. IT IS SO BAD THAT SAY IF I'M ON AN INCLINE HEADED UPWARDS THE VEHICLE WILL ROLL BACKWARDS AS I'M TRYING TO ACCELERATE AND I HAVE TO ROLL ALL THE WAY DOWN AND SHUT THE VEHICLE OFF AND RESTART AND TRY AGAIN UNTIL I CAN GET BACK TO THE HILL AND OVER IT AND SOMETIMES I HAVE TO ALLOW THE CAR TO SIT A FEW HOURS AND COME BACK TO GET IT TO MAKE IT WORK. THIS IS A VERY SERIOUS ISSUE THAT CAN AND WILL EVENTUALLY CAUSE AN ACCIDENT OR DEATH. ALSO AT A STOP LIGHT TO MAKE A LEFT OR RIGHT TURN I NEVER KNOW IF IT WILL ACCELERATE AS IT SHOULD THEREFORE I HAVE TO WAIT UNTIL THERE IS NO TRAFFIC AT ALL BEFORE ATTEMPTING TO MAKE MY TURN AND GET BACK INTO TRAFFIC. THERE IS NO CHECK ENGINE OR ANY WARNING LIGHTS OR SOUNDS WHEN THIS OCCURS. I HAVE CONSULTED WITH THE DEALER AND SEVERAL HYUNDAI SPECIALIST IN MY AREA AS WELL AS RESEARCHED THE PROBLEM ON THE INTERNET WHICH I FOUND IT SEEMS TO BE A COMMON PROBLEM BUT NO ONE HAS ANY ANSWERS AS THERE IS NO WAY TO SCAN THE VEHICLE WITHOUT A CHECK ENGINE OR WARNING LIGHT. THIS IS TERRIBLE AS MY VEHICLE ONLY HAS 56275 MILES ON IT AND I CAN NOT GET IT TO WORK CORRECTLY OR EVEN IDENTIFY THE PROBLEM. I AM UNWILLING TO CONTINUE TO PAY MONEY TO DEALERSHIPS WITH NO ANSWERS AND BECAUSE OF THIS ISSUE THE CAR IS UNSAFE TO DRIVE. IF ANYONE HAS ANY ANSWERS PLEASE HELP AS I DON'T EVEN WANT TO SELL THE VEHICLE AS IT IS UNSAFE TO DRIVE. THANK YOU.
