NHTSA Complaint #11019523 — 2002 HYUNDAI SONATA

I HAVE A HYUNDAI SONATA. ITS 2002 WITH 50,000 MILES ON IT. THE FIRST TIME IT GAVE ME TROUBLE, IT WAS MAKING A GRINDING SOUND WHILE DRIVING TO WORK. THE MECHANIC CHANGED MY CALIBER ON ONE SIDE OF THE CAR AND REPLACED MY HOSES. NEXT MONTH SAME SOUND STARTED AGAIN. MY MECHANIC CHANGED THE OTHER CALIBER. SIX MONTHS LATER. I STARTED HEARING THAT SAME SOUND AND THE BRAKES STARTED LOCKING. THE MECHANIC DIDN'T SEE ANYTHING WRONG. TWO WEEKS LATER, I LOST MY BRAKES WHILE DRIVING ON INTERSTATE 10. I WAS ABLE TO COAST TO A STOP WITHOUT ANY INCIDENTS. I HAD MY CAR TOWED TO MY MECHANIC.I WAS TOLD I DAMAGED THE MASTER CYLINDER. HE PUT ALL NEW PARTS IN MY CAR (BRAKE SHOES,PADS, CALIBERS, MASTER CYLINDER, ETC.) AND TESTED IT. THE NEXT DAY WHILE DRIVING ON I-10, IT STARTED LOCKING UP AGAIN. IT HAS BAFFLED MY MECHANIC. MY CAR IS STILL IN THE SHOP. I HAVE SPENT OVER $1500.00 ON REPAIRS OF THESE BRAKES,NOT TO MENTION THE RENTAL FEES OF CARS FOR TRANSPORTATION. THERE MUST BE AN ANSWER TO WHAT IS CAUSING MY BRAKES TO NO FUNCTION PROPERLY.
