NHTSA Complaint #10821857 — 2012 HYUNDAI SONATA

1/23/2016 8:02 AM I RECEIVED A CALL FROM MY WIFE WHO WAS DRIVING HER 2012 HYUNDAI SONATA ON THE I-95 IN SOUTH FLORIDA ON THE WAY TO WORK GOING APPROXIMATELY 70 MPH, WHEN SHE WENT TO ACCELERATE TO OVERTAKE A CAR DRIVING SLOWER. ALL THE LIGHTS ON THE DASHBOARD WENT ON AND THE CAR COMPLETELY LOST ACCELERATION POWER AND THE SPEED DROPPED ALL THE WAY DOWN TO 40 MPH. WHEN THE SPEED REACHED 40 MPH, SHE COULD NOT ACCELERATE ANYMORE AND HENCE QUICKLY PULLED OFF TO THE SIDE OF THE ROAD (UPON MY REQUEST). DUE TO THE HEAVY TRAFFIC, SHE WAS EXTREMELY LUCKY NOT TO GET INTO AN ACCIDENT. WHEN I ARRIVED TO SWITCH CARS WITH HER, THE CAR STARTED FINE AND ACCELERATED APPROPRIATELY. I TOOK IT STRAIGHT TO THE HYUNDAI DEALERSHIP WHO AFTER RUNNING DIAGNOSTICS CAME UP THE FOLLOWING: NO CODES STORED IN MEMORY AND NO SIGNS OF WHAT COULD HAVE CAUSED THE CAR TO ACT LIKE THIS. THEY RECOMMENDED A THROTTLE BODY CLEANING WHICH IS CURRENTLY BEING COMPLETED (I AM WRITING THIS FROM DELRAY BEACH HYUNDAI). THEY STATED THE THROTTLE BODY STICKING MAY BE THE CAUSE, BUT WENT ON TO ADMIT THEY REALLY HAD NO IDEA AS DIAGNOSTICS GAVE THEM NO INFORMATION. AFTER THIS INCIDENT, WE ARE CONCERNED THAT THE CAR IS NO LONGER SAFE TO DRIVE AND THE FACT THE DEALERSHIP HAS BEEN UNABLE TO COME UP WITH ANY CAUSE IS EVEN MORE OF A CONCERN.
