NHTSA Complaint #10159888 — 2001 MAZDA MPV

I HAVE A 2001 MAZDA MPV,BOUGHT IN 2001 FROM DEALER. NOW 5 YEARS LATER,ON THE DRIVERS SIDE LOWER CONTROL ARM, APPROXIMATELY 2 TO 3 IN. IN FROM BALL JOINT,THAT PORTION OF CONTROL ARM IS ABOUT TO FALL OFF OR TEAR DUE TO CORROSION. THAT I WOULD SAY IS A VERY CHEAP DESIGN BY THEIR ENGINEERS OF MAZDA CORP. I WAS VERY, VERY,FORTUNATE THAT MY WIFE WAS DRIVING IT THE MORNING WHEN IT WAS NOTICED. I HAVE A LONG DRIVEWAY BEFORE WE GET OUT TO THE HIGHWAY! SHE HEARD A VERY DISTINCT GRINDING OF METAL AND STOPPED THE VEHICLE TO CHECK IT OUT!WHAT A SCARY SIGHT! I STRONGLY FEEL YOU FOLKS NEED TO CHECK THAT PART OF MAZDA'S MPV! I FEEL IT IS TO THIN OF METAL TO BE USED FOR THAT PART. WHAT EVER HAPPENED TO CASTIRON????? THEY NEVER CORRODE. I HAVE NO WARRANTY LEFT ON AUTO. THE PART,THAT PART IS $324.00 PLUS LABOR. PLEASE HELP! ALOHA. *NM
