NHTSA Complaint #11396999 — 2017 HYUNDAI ELANTRA

MY 2017 HYUNDAI ELANTRA BEGAN TO SHAKE AND REFUSED TO SHIFT ABOVE 40MPHS ON A ROAD POSTED 45. THE ENGINE LIGHT CAME ON AND THE RMP GAUGE SHOW THAT IT WAS STUCK AT 2RMPS. I SLOWED THE VEHICLE AND TURN ON MY FLASHERS AND IN MY TRAVELING TO A SAFE PULL OFF LOCATION. THE ENGINE LIGHT WENT OFF, THE SHAKING STOPPED, AND THE CAR RESUME A NORMAL SHIFTING PATTERN. THE VERY NEXT DAY WHILE TRAVELING IN THE CAR THE SAME THING OCCURRED. I EXPLAINED THE PROBLEM WHEN ARRIVED AT HYUNDAI AND WHILE IDLING AND WAITING TO THE CAR PERSON TO CHECK ME IN. THE CAR BEGAN TO DO SHORT SHUDDERS; THIS WAS DIRECTLY WITNESSED BY A CAR SERVICE EMPLOYEE. THE 2ND CYLINDER IGNITION COIL WAS REPLACED. IN MY SECOND VISIT I WAS SURE OF WHAT THE PROBLEM WAS BECAUSE I HAD EXPERIENCED THE SAME CAR SYMPTOMS SEVERAL MONTHS EARLIER. HERE IS THE PROBLEM THIS WAS SECOND CYLINDER I HAVE HAD TO HAVE REPLACED IN ABOUT 3000 MILES AND SEVERAL MONTHS; MY CAR ONLY HAS 25,0000 MILES. THIS IS A KNOWN ISSUE ON THE REPAIR FORM IT STATES ECU UPGRADE.
