NHTSA Complaint #11024510 — 2012 KIA OPTIMA HYBRID

ON TWO SEPARATE OCCASIONS, I WAS DRIVING WITH MY CHILDREN IN THE CAR AND HAVE LOST BRAKE FUNCTIONS TO MY CAR. THE FIRST TIME, I WAS ON THE FREEWAY. IN THE MORNING WITH ALOT OF TRAFFIC. I HAD TO SWERVE INTO THE EMERGENCY LANE AND GRIND THE BRAKES TRYING TO STOP THE CAR. THERE WAS A LOUD GRINDING AND SCRAPPING SOUND BUT CAR DID NOT STOP. I HAD TO USE EMERGENCY BRAKE TO STOP THE CAR. I TURNED OFF THE CAR AND RESTARTED IT AND THE BRAKES WORKED AGAIN. I WAS ABLE TO EXIT THE FREEWAY AND SLOWLY MADE IT TO MY HOME. I THEN HAD THE CAR TOWED TO AN AUTO SHOP NEAR BY. THEY RAN A DIAGNOSTIC AND FOUND CODE ERROR 1237 IN THE ACTIVE HYDRAULIC BOOST SYSTEM AND WAS TOLD THAT THE CAR HAS AN INTERNAL PRESSURE LEAK IN THE ABS SYSTEM. THE MECHANIC WAS NOT ABLE TO FIX THE ISSUE DUE TO NOT HAVING THE EQUIPMENT TO DO SO AND I WAS SENT TO KIA DEALER. I TOWED THE CAR TO KIA. I TOLD THEM WHAT THE MECHANIC HAD SAID AND I WAS TOLD THAT KIA NEEDED TO RUN ITS OWN DIAGNOSTIC. AFTER THEY DID THAT THEY SAID IT WAS THE BATTERY. I REPLACED THE BATTERY. 3 MONTHS LATER, THE SAME THING HAPPENED. I WAS JUST ABOUT TO ENTER THE FREEWAY WHEN I LOST THE BRAKES AND HEARD THE GRINDING AND SCRAPPING SOUND. I PULLED INTO A GAS STATION RIGHT BEFORE THE FREEWAY AND WAS ABLE TO STOP THE CAR USING MY EMERGENCY BRAKE. I AGAIN TURNED OFF THE CAR AND TURNED IT BACK ON. I TRIED TO DRIVE IT BUT IT CONTINUED TO HAPPEN. I COULD NOT DRIVE IT SAFELY SO I HAD IT TOWED TO KIA. THEY DID ANOTHER DIAGNOSTIC AND TOLD ME THAT THEY HAD FOUND A PRESSURE SENSOR ERROR AND A LEAK IN THE ABS SYSTEM AND NOW ITS GOING TO COST 2600. THEY COULD NOT GUARANTEE ME THAT THIS WOULD NOT HAPPEN AGAIN. I DO NOT FEEL SAFE DRIVING ME AND MY FAMILY IN THE CAR.
