“AS I WAS APPROACHING AN INTERSECTION AND I STARTED TO APPLY THE BRAKES, THE VAN SUDDENLY ACCELERATED, WHEN I PRESSED HARD ON THE BRAKE STILL IT WOULDN'T STOP...CALL KIA SEDONA AUTHORIZED DEALER, THEY SAID THERE'S NO RECALL. AS I RESEARCHED THE INTERNET, I NOTICE THAT CAR GURUS(WHICH IS A CAR FORUM) OVER 33 PEOPLE HAD COMPLAINT WITH THE SAME PROBLEM. THERE WERE AN ACCIDENT WITH FATALITIES EVEN. I'M VERY CONCERN AS I DRIVE WITH ALL MY KIDS SPECIALLY MY GRANDSON OFTEN, AND IT SCARES THE CRAP OUT OF ME TO THINK THAT I WOULD GET INVOLVED IN AN ACCIDENT WITH THE LITTLE ONE ON BOARD. A LOT OF PEOPLE DID THE DIAGNOSTICS THAT THE DEALER SUGGESTED, AFTER PAYING OVER $110 PLUS TAXES, THE CAR IS STILL SHOWING THE SAME PROBLEM. I REALLY NEED SOMEBODY TO TELL ME WHAT AM I SUPPOSED TO DO? I'M STILL PAYING FOR THE VEHICLE, I'M SCARED TO DRIVE IT ANYWHERE SPECIALLY THE HIGHWAY...HELP PLEASE... *TR”

THE SECOND INCIDENT OCCURRED WHILE I WAS DRIVING UP A HILL. THE VAN STARTED ACCELERATING AND I WAS NOT ABLE TO USE MY BRAKES. THIS TIME I PUT THE VAN IN NEUTRAL AND WAS ABLE TO REGAIN CONTROL OF THE VAN. I TOOK THE VAN TO MY MECHANIC AND THEY DID NOT FIND ANY PROBLEM WITH THE BRAKES OR ANYTHING ELSE. MY FRIEND ALSO EXPERIENCED A SIMILAR INCIDENT WITH HER NEWER MODEL KIA SEDONA AND USES MY SAME MECHANIC AND FOUND NOTHING WRONG. HER INCIDENT HAPPENED BEFORE MY FIRST EPISODE IN JUNE. TODAY, I WAS DRIVING MY DAUGHTER TO WORK AND THE SAME THING HAPPENED AS I WAS DRIVING UP A SLIGHT ELEVATED STREET. I WAS NOT ABLE TO USE THE BRAKES AND SHIFTED INTO NEUTRAL.
