NHTSA Complaint #10473846 — 2012 KIA SORENTO

ON 08/12/12 WHILE DRIVING IN CRUISE CONTROL AT APPROXIMATELY 72-74 MPH, I EASED OUT INTO THE PASSING LANE TO PUT MYSELF BEHIND SOMEONE GOING FASTER. THE CAR SUDDENLY DOWNSHIFTED AND ACCELERATED WITH MAXIMUM THROTTLE. I TOUCHED THE BRAKE PEDAL MODERATELY TO DISCONNECT THE CRUISE CONTROL. THE CAR CONTINUED AT MAXIMUM ACCELERATION AND IN THE PASSING GEAR. I THEN APPLIED THE BRAKES WITH GREAT VIGOR AND THE CRUISE CONTROL DISCONNECTED AND THE VEHICLE SLOWED DOWN. AFTER A SHORT WHILE I REACTIVATED THE CRUISE CONTROL AND DROVE ABOUT 60 MILES WITHOUT ANY FURTHER MALFUNCTION. I PRESENTED THE CAR TO THE KIA DEALER SERVICE ADVISOR. THE CAR WAS CHECKED AND I WAS TOLD THEY COULD FIND NOTHING WRONG WITH THE CRUISE CONTROL. I ASKED THEM IF THEY REPORTED THESE VERY DANGEROUS OBSERVATIONS TO KIA OR NHTSA. THEY SAID NO THEY NEVER DO. INCIDENTAL TO THIS EVENT, I HAD AN ENGINE MALFUNCTION LIGHT ON 7/25/12. I TOOK IT IN FOR SERVICE THE NEXT DAY AND TOLD IT WAS A TRANSMISSION HEAT SENSOR. A PART WAS ORDERED AND I WAS TOLD TO DRIVE THE CAR NORMALLY. WITHIN SEVERAL DAYS, I BECAME AWARE THE CRUISE CONTROL WAS NOT ACTIVATING WHEN DRIVING THE FIRST TIME IN A DAY. BUT IF THE ENGINE WAS STOPPED AND RESTARTED, THE CRUISE CONTROL WORKED NORMALLY. I DUPLICATED THIS 3 DISTINCT TIMES EXACTLY AS WRITTEN. THE SERVICE DEPARTMENT WAS NOT ABLE TO LINK THE DIFFICULTY TO ANYTHING THEY HAD SEEN OR READ, THEY SUMMERIZED IT MAY HAVE BEEN A BRAKE LIGHT SENSOR THAT FAILED BUT THE COMPUTER DISPELLED THAT NOTION. *TR
