NHTSA Complaint #10239652 — 2006 HYUNDAI SONATA

TL*THE CONTACT OWNS A 2006 HYUNDAI SONATA. WHILE DRIVING 60-70 MPH, THE SPEED WOULD DECREASE TO 20-30 MPH WITHOUT WARNING. THE VEHICLE WOULD NOT SHUT OFF, BUT IT WOULD JERK REPEATEDLY WHILE IT DECELERATED. THE FAILURE OCCURRED WITHOUT THE BRAKE PEDAL BEING DEPRESSED AND HAS TAKEN PLACE NUMEROUS TIMES. THE VEHICLE WAS TAKEN TO THREE DIFFERENT DEALERS. INITIALLY, THE TRANSMISSION WAS REPLACED, BUT THE FAILURE RECURRED 1,400 MILES LATER. SECONDLY, THE DEALER STATED THAT THE CYLINOID NEEDED TO BE REPLACED. THE REPAIRS WERE COMPLETED, BUT THE FAILURE RECURRED 1,600 MILES LATER. THE THIRD DEALER STATED THAT THERE WAS ANOTHER CYLINOID THAT NEEDED TO BE REPLACED AND THE REPAIR WAS MADE. TWO WEEKS LATER, THE VEHICLE CONTINUED TO JERK AT SPEEDS NO GREATER THAN 70 MPH. THE VEHICLE JERKED BACK TO 20 MPH AUTOMATICALLY. THE DEALER TEST DROVE THE VEHICLE AND THE SUPERVISOR STATED THAT HE HAD NEVER BEFORE EXPERIENCED THIS TYPE OF TRANSMISSION FAILURE. THE DEALER STATED THAT THE ELECTRICAL HARNESS NEEDED TO BE REPLACED. THE REPAIRS WERE COMPLETED; HOWEVER, THE DEALER STATED THAT THEY COULD NOT GUARANTEE THE FAILURE WOULD NOT OCCUR AGAIN. AFTER THE REPAIRS WERE PERFORMED, THE INSTRUMENT PANEL FAILED. A POLICE REPORT WAS FILED. THE FAILURE MILEAGE WAS 38,000 AND CURRENT MILEAGE WAS 188,000.
