SO I THOUGHT I HAD A SIMPLE THERMOSTAT ISSUE. WENT TO CHANGE THE THERMOSTAT AND NOTICED THE MANIFOLD HOUSING (PLASTIC) HAD A NICE CRACK IN IT. WHEN DOING RESEARCH ON THIS, I NOTICED THERE HAVE BEEN NUMEROUS COMPLAINTS/INSTANCES OF THIS HAPPENING TO OTHER PEOPLE. NOW I AM IN THE PROCESS OF FINDING A NEW INTAKE MANIFOLD AND WILL HAVE TO PAY TO HAVE IT INSTALLED. THIS SEEMS TO BE AN ISSUE THAT THE DEPARTMENT OF TRANSPORTATION SHOULD BE INVOLVED IN. POOR MANUFACTURE DESIGN WITH NUMEROUS INCIDENTS OF FAILURE THAT RESULT IN UNNECESSARY HIGH REPAIR COSTS PLACED ON THE CONSUMER. I AM THE ORIGINAL OWNER OF THIS VEHICLE AND THINK IT IS RIDICULOUS! *TR

FORD DESIGNED THE A/C DRAIN LINE LOCATED ABOVE THE RIGHT EXHAUST PIPE LEADING TO THE CATALYTIC CONVERTER ON THE 3.8 LITER V6 ENGINE. THE COLD CONDENSATION FROM THE A/C DRIPPING ONTO THE PIPE CAUSES THE PIPE TO CRACK OR IN SOME CASES CAUSES THE CATALYTIC CONVERTER TO RUPTURE OR CRACK. THIS IS AN EXPENSIVE REPAIR. I KNOW OF 3 PEOPLE IN MY BUSINESS THAT THIS HAS HAPPENED TO IN JUST THE PAST 6 MONTHS. ONE CASE THE CONVERTER HAD TO BE REPLACED AND IN THE OTHER 2 THE EXHAUST PIPE HAD TO BE REMOVED AND WELDED AT THE CRACKS. STAINLESS STEEL PIPES ARE WELDED DIFFERENT THEN THE OLD STEEL PIPES AND REQUIRE A SPECIAL WELDING TECHNIQUE AND EQUIPMENT DRIVING UP THE COST OF THE REPAIR. THIS CRACK LEFT UNATTENDED COULD LEAD TO CARBON MONOXIDE ENTERING THE COCKPIT AREA. *TR

TOOK MY 2000 MUSTANG TO THE DEALER TO REPAIR A KNOCKING PROBLEM I WAS HEARING WHEN THE CAR ACCELERATED. EVENTUALLY AFTER 3 VISITS AND TALKING TO 3 SERVICE ADVISORS THE KNOCKING WAS HEARD. THEY REPLACED $1300 WORTH OF PARTS, AND SAID IT WAS FIXED. DROVE IT NO MORE THAN 10 MINUTES AND TOOK IT RIGHT BACK BECAUSE THE KNOCKING WAS NOT FIXED. THEY THEN TOLD ME THAT THE MOTOR WAS SOMETHING INSIDE THE MOTOR. SO I HAD IT REPLACED. WAS RETURNED 1 WEEK LATER DUE TO A PROBLEM WITH IT STAYING RUNNING. THE PROBLEM WAS IDENTIFIED AS A ROCKER ARM THAT HAD COME LOOSE. THE CAR WAS RETURNED 2 WEEKS LATER FOR THE SAME KNOCKING ISSUE THAT WAS ORIGINALLY REPORTED AND NO ONE KNEW WHAT IS WRONG WITH IT.*AK

A/C CONDENSATION DRAIN TUBE DRIPS ON EXHAUST MANIFOLD CAUSING THE EXHAUST TO BRAKE. ITS AN ON-GOING PROBLEM THAT SHOULD BE CORRECTED. THE ONLY REMEDY IS TO WELD THE TUBE BACK TOGETHER. FROM MANY SHOPS I'VE SPOKEN TO THIS IS A PROBLEM THEY SEE AND KNOW A LOT ABOUT. *NM
