NHTSA Complaint #10910965 — 2011 HYUNDAI SONATA

9/30/2016 - WHILE DRIVING HOME FROM WORK (20-25 MILES) HEARD A KNOCKING IN THE ENGINE WHILE ON THE ROAD AND EXPRESSWAY. TOOK MY CAR TO JIFFY LUBE BECAUSE IT WAS TIME FOR AN OIL CHANGE AND HAD THEM CHECK THE ENGINE AND NOISE. THEY ADVISED THAT THE ENGINE IS BAD AND WILL NEED TO BE REPAIRED OR REPLACED. THE MILES FROM MY LAST OIL CHANGE WAS APPROXIMATELY 3200 MILES. TOOK MY CAR TWO BLOCKS DOWN THE ROAD TO MIDAS AND ANOTHER MECHANIC CONFIRMED THE ENGINE NEEDS TO BE REPLACED. I HAVE TAKEN CARE OF THE CAR WITH REGULAR OIL CHANGES, UPKEEP AND CAR MAINTENANCE. ON 1/11/2016 MY 2011 HYUNDAI SONATA ENGINE WAS TAKEN IN FOR THE RECALL CAMPAIGN 132 AT THE HYUNDAI REPAIR LOCATION. IN JUNE, I TOOK MY CAR IN FOR SERVICE AT FIRESTONE AUTO CARE BECAUSE MY ENGINE LIGHT HAD CAME ON AND THEY PERFORMED AN ENGINE ANALYSIS AND FOUND MY OXYGEN SENSOR WAS BAD ON 6/04/2016 AND THEY REPLACED THAT. I CANNOT DRIVE THE VEHICLE BECAUSE THE ENGINE IS ON ITS LAST LEG, CANNOT ACCELERATE BECAUSE THE CAR IS NOT RESPONDING AS IT SHOULD AND I FEAR I AM RISKING MY LIFE AS WELL AS OTHERS ON THE ROAD. THE DIFFERENCE BETWEEN DRIVING FROM 9/29 TO 9/30 IS NIGHT AND DAY I DO NOT UNDERSTAND HOW AN ENGINE GIVES OUT WITH NO WARNING.
