WHEN I PURCHASED THE CAR IN JUNE 1999 THE PREVIOUS OWNER (WHO HAD BOUGHT THE CAR NEW HIMSELF) HAD ALREADY HAD THE ROTORS REPLACED 1 TIME AND TURNED 5 TIMES. WHEN I BOUGHT THE CAR I IMMEDIATELY HAD NEW ROTORS PUT ON. SINCE THEN I HAVE HAD THE ROTORS REPLACED 1 MORE TIME AND TURNED 5 MORE TIMES. AND AFTER I GET THEM TURNED IT USUALLY ONLY TAKES A WEEK OR TWO FOR THE ROTORS TO WARP AGAIN AND THE TERRIBLE VIBRATION WHEN BRAKING RETURNS. I ALSO HAVE A LEAK IN THE BRAKE LINE SOMEWHERE. I HAVE TO "TOP OFF" THE BRAKE FLUID AT LEAST EVERY COUPLE OF WEEKS. AND I HAVE NO EMERGENCY BRAKE. PLEASE HELP!! AS A SINGLE MOM WITH A 2 AND 4 YEAR OLD IT IS VERY DIFFICULT TO KEEP HAVING TO HAVE THE SAME PROBLEM REPAIRED OVER AND OVER--NOT JUST BECAUSE OF COST BUT BECAUSE OF THE TIME INVOLVED IN BEING AT THE DEALER FOR THE REPAIRS TO BE DONE. NOT TO MENTION THE SAFETY ISSUE--ESPECIALLY WITH MY BABIES RIDING IN THE CAR. IT SHAKES ALL OVER THE ROAD WHEN I PUT MY BRAKES ON AND I'M ALWAYS CONCERNED THAT THE BRAKES JUST MIGHT QUIT WORKING ALL OF A SUDDEN. I SEE IN THE COMPLAINT SECTION OF YOUR WEB SITE THAT THERE ARE NUMEROUS COMPLAINTS ABOUT PREMATURE WEAR OF THE BRAKE ROTORS AND VIBRATING WHEN BRAKING. IF THIS IS A CONTINUING PROBLEM, BUT IS NOT OFFICIALLY A "RECALL" YET, IS THERE SOME WAY THAT I CAN GET SOME ASSISTANCE ON GETTING THIS PROBLEM FIXED ONCE AND FOR ALL AT THE MANUFACTURER'S EXPENSE? I'VE ALREADY SPENT MORE THAN I COULD AFFORD TO TRY TO FIX THE PROBLEM, BUT IT ISN'T FIXED. AND I DON'T HAVE ANY MORE MONEY THAT I CAN PUT INTO THIS PROBLEM, BUT CAN'T AFFORD TO REPLACE THE CAR. SO SOMETHING NEEDS TO BE DONE. HELP!!*AK

THE ABS SYSTEM HAS BEEN AN ONGOING PROBLEM FOR THIS VEHICLE SINCE IT WAS PURCHASED. THE PROBLEM IS THAT THE ABS SYSTEM WILL "ENERGIZE" AT TIMES WHEN THERE IS NO SLIPPAGE OF THE WHEELS. THERE ARE TIMES WHEN THE ABS SYSTEM ENERGIZES WITH THE VEHICLE IDLING IN PARK. WHEN THE VEHICLE IS IN MOTION, IF THE ABS SYSTEM ENERGIZES, AND THE DRIVER HAS TO USE THE BRAKES, THE BRAKING ACTION IS SUDDEN AND EXTREME, CREATING A VERY DANGEROUS CONDITION. THE REPAIRING DELERSHIP (MANHATTAN LINCOLN MERC, 301 424-7000, "MIGUEL") HAS EFFECTIVELY GIVEN UP ON SOLVING THIS PROBLEM, AFTER A CONSULT FROM FORD (ENGINEER, ERNIE PECK?). WE HAVE NO CHOICE BUT TO GET RID OF THIS CAR, BECAUSE OF SAFETY CONCERNS FOR MY WIFE AND OUR 11 MONTH OLD.*AK
