THE CAR ALL OF THE SUDDEN STARTED LOOSING BRAKE FLUID RAPIDLY. MY PERFECTLY GOOD BRAKES WERE GOING OUT AND I ALMOST WRECKED MY CAR BECAUSE OF THIS PROBLEM. THE KIA DEALERSHIP IN DICKINSON, TX IS CHARGING ME 300 DOLLARS + TO FIX THIS PROBLEM. I SEE THAT THOUSANDS OF PEOPLE HAVE HAD THIS PROBLEM WITH A DEFECTIVE MANUFACTURE PART. MY MECHANIC SAID THAT THIS WAS THE FIRST PROPORTIONING VALVE HE HAS SEEN COMPLETELY DESTROYED LIKE THIS IN 10+ YEARS. THIS IS HAPPENING TO THOUSANDS OF PEOPLE. I HAVE WROTE ALL NEWS STATIONS ABOUT THIS AND I AM PURSUING THIS AGGRESSIVELY. YOU ALL RECALLED THE 2004-2007 PROPORTIONING VALVES THEN IT SHOULD BE FOR THE EARLIER MODELS AS WELL. *TR

PURCHASED THE CAR IN MAY OF 2003, JUNE 30TH OF 2003 CHECK ENGINE LIGHT CAME ON AND HAD TO HAVE THE TPS REPLACED AND 3 MORE TIMES TO PRESENT. HAVE HAD MULTIPLE HEADLIGHTS REPLACED, HEATING PROBLEM, EXHAUST REPLACED. CAR IS NOW ON 46,000 HAD TRANSMISSION REPLACED (THROUGH AN ATT. FROM LEMON LAW) AT 16,000 MILES HAD TO HAVE TIRES REPLACED. AND, NOW TO DATE TIRES WERE REPLACED FOR THE 5TH TIME, BRAKES WERE DONE 4 TIMES, NOW TO FIND OUT THE REASON TIRES AND BRAKES WERE NEEDED TO BE REPLACED SO MANY TIMES IS BECAUSE THE SUSPENSION IS WAY OUT OF ALIGNMENT WHICH SEEING I HAVE HAD THE PROBLEM ALL ALONG I NOW BELIEVE IT WAS A DEFECT ALL ALONG. *JB

THE BRAKE PROPORTIONING VALVE IS LEAKING AND THE CAR IS CURRENTLY IN THE SHOP HAVING THIS REPLACED. THIS IS A 2003 KIA SPECTRA. THIS PART APPEARS TO BE A MANUFACTURER'S DEFECT AS THERE ARE OTHER COMPLAINTS LISTED HERE AND ELSEWHERE. HAS THERE BEEN A RECALL AS THIS IS A SAFETY ISSUE THAT I CANNOT BELIEVE IS LIMITED TO MY VEHICLE. ALSO, THE INTERIOR COMPONENTS STARTED FALLING OFF WITHIN 6 WEEKS OF OWNERSHIP. THE CONSOLE LID BROKE, THE CAPS FOR THE GAS RELEASE LEVER AND THE TRUNK LEVER HAVE ALL COME OFF NUMEROUS TIME. THE CAR JACK SNAPPED THE FIRST AND ONLY TIME IT WAS USED TO CHANGE A FLAT TIRE. *JB
