NHTSA Complaint #11279846 — 2018 HYUNDAI SONATA

ON FIVE SEPARATE OCCASIONS WHILE DRIVING ON THE HIGHWAY THE VEHICLE WILL LOOSE POWER AND ABILITY ACCELERATE WITH A FLASHING ENGINE LIGHT. THESE INCIDENTS HAVE ALMOST CAUSED ME TO BE REAR ENDED THREE TIMES BECAUSE YOU ARE NOT ABLE TO ACCELERATE ABOVE 60MPH IN RUSH HOUR TRAFFIC ON A BUSY INTERSTATE AND THE ABILITY JUST STOPS QUICKLY WITH NO WARNING. THE VEHICLE ALSO HAS BEEN HAVING THE RPMS DROP TO 0 AND SHOOT BACK UP WHILE BRAKING, AND WHILE DRIVING IT IS TOUGH TO ACCELERATE AND THEN YOU WILL FEEL A NOTICEABLE 'KICK' AND THE RPMS WILL SHOOT UP DRASTICALLY BEFORE IT WILL ACCELERATE. I HAVE HAD 2 SOFTWARE UPDATES DONE, A NEW WIRE HARNESS, KNOCK SENSOR CLEANING AND A KNOCK SENSOR REPLACEMENT. THE ENGINE CODE IS ALWAYS THE SAME 1326.
