2002 CHEVROLET TRACKER Steering Problems

MY MOTHER AND I WAS DRIVING ON THE EXPRESSWAY AND IT SEEMED AS IF THE CAR JUST LUNGED FORWARD SHARPLY AND MADE US SWERVE A LITTLE. I PULLED OVER AND SEEN THAT THE CAR WAS SITTING "OFF" A LITTLE. WE TOWED IT HOME AND MY STEP DAD LOOKED AT IT AND SAID THE CAR HAD RUSTED THROUGH THE SUBFRAME. THE SUBSPENSION SUBFRAME CROSSMEMBER PART COULD OF KILLED US. SHE BOUGHT THIS CAR AT 29 MILES FROM DAVE WHITE CHEVEROLT IN 2001. NOTHING WAS SENT TO US FROM THE MANUFACTURE OR THE DEALERSHIP ABOUT THIS PART BEING A DANGEROUS PART. IT WAS TO BE REPLACED I HEARD IF THE CAR REACHED 150,000 MILES OR 10 PLUS YEARS. SHE HAD THIS CAR FOR BOTH AND WAS NOT NOTIFIED. THE DEALERSHIP WILL NOT REPLACE THE PART. WE HAD IT TOWED THIS WEEKEND AND THE DEALERSHIP WILL NOT REPLACE THE PART FOR FREE.

TL*THE CONTACT OWNS A 2002 CHEVROLET TRACKER. WHILE DRIVING APPROXIMATELY 35 MPH, THE CONTACT HEARD A LOUD POPPING NOISE, WHEN HE LOST POWER STEERING MAKING IT DIFFICULT TO CONTROL THE VEHICLE. A PRIVATE MECHANIC INFORMED THE CONTACT THAT THE CROSS MEMBER OF THE FRONT SUSPENSION WAS CORRODED. THE DEALER WAS NOTIFIED AND INFORMED THE CONTACT THAT THEY WOULD BE REPAIR THE CROSS MEMBER; HOWEVER, THE UPPER CONTROL ARM WAS CORRODED AND THE WARRANTY WOULD NOT COVER THE PROCEDURE. THE MANUFACTURER WAS CONTACTED AND ADVISED THE CONTACT TO TAKE THE VEHICLE TO THE DEALER FOR DIAGNOSTIC TESTING. THE CURRENT AND FAILURE MILEAGES WERE 117,004.
