NHTSA Complaint #10873128 — 2012 HYUNDAI SONATA

AS I WAS DRIVING HOME AFTER WORK ON FRIDAY AROUND 2130, I WAS DRIVING ON THE EXPRESSWAY ABOUT 65-70MPH WHEN I NOTICED THAT THE CAR WAS DECLINING IN SPEED WITHOUT ME LETTING UP ON THE GAS PEDAL. I WAS IN A FAIR AMOUNT OF TRAFFIC WITH A SEMI BEHIND ME, I PRESSED DOWN FURTHER ON THE GAS PEDAL TO TRY AND INCREASE SPEED WHILE LOOKING FOR A WAY TO SAFELY GET OFF OF THE EXPRESSWAY. THE CAR INITIALLY DID NOT SPEED BACK UP, AFTER APPROXIMATELY 10-15 SECONDS, IT SPED BACK UP. THE CAR DID THIS THREE TIMES DURING MY, NORMALLY 25 MINUTE, DRIVE HOME. THIS WAS EXTREMELY SCARY, ESPECIALLY BEING IN HEAVY CHICAGO TRAFFIC. I CALLED THE DEALERSHIP FIRST THING SATURDAY MORNING AND MADE AN APPOINTMENT TO GET IT CHECKED. THE FIRST AVAILABLE APPOINTMENT WAS TODAY, TUESDAY, AND I HAD THE VEHICLE THERE AT 0700. THE VEHICLE WAS SCANNED AND PULLED SEVERAL CODES: C1283, C1213, C1513, B1102, B112, C1334, C1335, C1126, C1662, C1312, C1314, AND C1315. THEY THEN PERFORMED INDIVIDUAL CODE DIAGNOSTICS AND TRACED CODE FAILURES TO YAW-RATE SENSOR, BRAKE PEDAL POSITION SENSOR AND EVAP PURGE SOLENOID. ESTIMATED $1276.97 + TAX.
