2006 MERCURY MOUNTAINEER. CONSUMER WRITES IN REGARDS TO FAILURE OF THE WATER MANIFOLD HOUSING. *SMD THE CONSUMER STATED HE WAS DRIVING 70 MPH, WHEN THE ENGINE LIGHT ILLUMINATED. THE VEHICLE BEGAN TO OVERHEAT AND STEAM WAS COMING FROM UNDER THE HOOD. THE WATER MANIFOLD HOUSING HAD COME APART, ALLOWING WATER TO BOIL OUT. THE HOUSING WAS PLASTIC AND MADE OF TWO PARTS. THE TOP AND BOTTOM WERE GLUED TOGETHER AND WITHIN THE TOTAL CIRCUMFERENCE OF ABOUT 18 INCHES, THERE WERE ONLY THREE BOLTS BETWEEN THE TOP AND BOTTOM HOUSINGS TO SECURE THE TWO PARTS TOGETHER, EXCEPT THE GLUE. THE CONSUMER BELIEVED THE CONSTRUCTION WAS NOT ENOUGH TO KEEP THEM FROM SEPARATING UNDER PRESSURE. IT APPEARED, THE DESIGN CREATED A TENDENCY FOR THE TOP PLATE TO PULL AWAY FROM THE LOWER HOUSING. THE CONSUMER ATTEMPTED TO INSTALL A NEW HOUSING, BUT HE DISCOVERED THE ENGINE WAS MISFIRING, SO THE VEHICLE HAD TO BE TOWED TO THE DEALER, WHERE THE LONG BLOCK ASSEMBLY WAS REPLACED.*JB

HAD A LEAK IN MY RADIATOR WHEN THE TRUCK HAD LESS THEN 25,000 (SUMMER OF 2009?) MILES LOGGED ON IT. TOOK IT TO THE DEALERSHIP AND THEY REPLACED IT FOR FREE BECAUSE IT WAS UNDER WARRANTY. AGAIN THIS SPRING, WITH MY ODOMETER AT 52000 MILES, IT HAS ANOTHER LEAK AND I WAS QUOTED $800 TO GET IT REPLACED BECAUSE IT IS NO LONGER UNDER WARRANTY. THIS IS B.S.! OBVIOUSLY IT IS A KNOWN PROBLEM. I HAVE NOT HAD IT FIXED YET BECAUSE I DON'T HAVE THE TIME TO LEAVE IT AT THE DEALERSHIP, OR THE $800 TO REPLACE A RADIATOR THAT SHOULD NOT NEED TO BE REPLACED AFTER SUCH A SHORT AMOUNT OF USE. THIS ISSUE NEEDS TO BE RECTIFIED BY FORD! IT HAS MADE ME NEVER WANT TO BUY ANOTHER FORD VEHICLE, EVER! *TR

IN JULY 2009 AT 40000 MILES THE RADIATOR HAD A HAIRLINE FRACTURE AND THE RADIATOR HAD TO BE REPLACED, PAID OUT OF POCKET BY OWNER. IN MARCH 2010, AT 60000 MILES, ANOTHER RADIATOR IS BEING PUT IN THIS VEHICLE, AGAIN OUT OF POCKET EXPENSE FOR OWNER. THERE SHOULD NOT BE A NEED FOR A VEHICLE TO HAVE HAD 3 RADIATORS AT 60000 MILES. THE DEALERSHIP STATES THIS IS A KNOWN ISSUE WITH THIS MODEL AND THAT THESE ARE POORLY PLACED AND MANUFACTURED RADIATORS. FORD/MERCURY SHOULD RECALL THESE VEHICLES AND REIMBURSE OUT OF POCKET EXPENSES FOR ANYONE THAT HAS PROOF OF RADIATORS BEING REPLACED. *TR

THE RADIATOR COOLANT SYSTEM IS JUNK. BUSTED SEALS AND HOSES ALL THE TIME. I AM BEGINNING TO THINK THIS CAR IS A LEMON. I REPLACED MY RADIATOR LESS THAN 1 YEAR AGO, HAD THE PART REPLACED WITH THE FACTORY PART FORD SUPPLIES AND ONCE AGAIN I HAVE A BUSTED SEAL AND HAVE TO REPLACE THE RADIATOR AGAIN. WHEN ARE THEY GOING TO RECALL THIS PART? SERIOUSLY I'VE DONE MY RESEARCH AND THE RADIATORS ON THESE VEHICLES BUSTING ISN'T AN ISOLATED INCIDENT. IS FORD GOING TO PAY $400.00 DOLLARS EVERY 6 OR SO MONTHS TO REPLACE MY RADIATOR. I WISH SOMEONE WOULD FILE A CLASS ACTION LAW SUIT OR SOMETHING. *TR

SOME THING NEEDS TO BE DONE ABOUT THE RADIATOR PROBLEMS MERCURY IS HAVING ON THE 2006 MOUNTAINEERS. MY VEHICLE IS VERY WELL MAINTAINED AND DON'T EVEN HAVE 60,000 MILES ON IT YET.I COMPLETELY UNDERSTAND THERE WILL ALWAYS BE SOME KIND OF MECHANICAL ISSUES TO DEAL WITH NOTHING LAST FOREVER, BUT MOST RADIATORS USUALLY OUTLAST THE VEHICLE. *TR

AS OF APRIL 18,2011 MY RADIATOR IS CRACKED AND I HAVE TO REPLACE IT FOR THE THIRD TIME. MY MERCURY MOUNTAINEER IS A 2006 AND IN 2008 I HAD TO REPLACE THE RADIATOR WHICH COST ME AROUND 800.00 WITH LABOR AND HERE WE ARE IN APRIL OF 2011 AND I HAVE TO REPLACE MY RADIATOR AGAIN. THIS IS COSTING ME TO MUCH MONEY AND WITH ALL THESE COMPLAINTS ABOUT THE RADIATOR, YOU WOULD THINK THAT THEY WOULD HAVE A RECALL ON THE 2006 MERCURY MOUNTAINEER RADIATOR. SOMEBODY NEEDS TO DO SOMETHING ABOUT THIS BECAUSE A RADIATOR SHOULD NOT HAVE TO BE REPLACE 3 OR MORE TIME IN LESS THEN 5 YEARS. PLEASE DO SOMETHING ABOUT THIS. THANKS *TR

2006 MERCURY MOUNTAINEER DRIVING ON THE HIGHWAY, SUDDENLY THE COOLANT TEMPERATURE WENT UP CRAZILY AND THE ENGINE SOUNDED HORRIBLE AND LOST POWER. FORTUNATELY STOPPED BY THE ROADSIDE AND FOUND THE RADIATOR WAS LEAKING AND COOLANT IS ALMOST EMPTY. SEARCHED AROUND THE WEB AND FOUND THAT FOR 4.0 ENGINE FROM FORD AND MERCURY, THIS IS PRETTY NORMAL PROBLEM DUE TO A DESIGN DEFECT. PEOPLE ARE CHANGING RADIATOR EVERY YEAR. NEVER HEARD SUCH RIDICULOUS THING THAT NOWADAYS THE RADIATOR LAST SO SHORT TIME. IT SHOULD LAST LIFE TIME OF THE CAR. FORD APPARENTLY KNEW IT, HOWEVER, THEY ONLY ANNOUNCED A TSB IN 2009 WHEN MOST OF THE WARRANTIES WERE GONNA EXPIRE. THEY SHOULD ISSUE A RECALL. THIS IS A DESIGN PROBLEM AND IT POSES LIFE THREATENING RISKS. I GUESS THEY JUST DON'T CARE ABOUT CUSTOMERS. THE CUSTOMERS NEED TO REPAIR OUT OF THEY OWN POCKETS, WHICH SUPPORT FORD'S CHAIN DEALERS SERVICE DEPARTMENTS. WELL, SOUNDS A GOOD PLAN FOR THEM. WELL, THE CUSTOMERS ARE NOT STUPID. THEY ARE CHANGE TO JAPANESE CARS, WHICH HAVE FAR LESS PROBLEMS. I WILL NEVER A FORD?MERCURY CAR AND WOULD BE GLAD TO SEE THEM GO BANKRUPTCY. *TR

CRACKED RADIATOR WITH ONLY 41,000 MILES. DEALERSHIP INDICATED REPAIR COST WOULD BE $1,000. WHEN I QUESTIONED POSSIBLE DEFECT THEY SAID THEY HAD NO RECALLS BUT ALSO INDICATED THEY HAD JUST REPLACED ANOTHER ONE LAST WEEK. I CALLED ANOTHER DEALERSHIP TO CHECK PRICE THEY ESTIMATED $750 AND ALSO INDICATED THEY HAD TO REPLACE 2-3 IN THE LAST FEW MONTHS.

HAD TO REPLACE TWO RADIATORS WITHIN 30,000 MILES OF REPLACEMENT. EXACTLY HOW MANY COMPLAINTS, OR SHOULD I SAY DEATHS (?) ARE NEEDED TO TRIGGER AN INVESTIGATION OF A COMPANY GLADLY RECEIVING ASSISTANCE WHILE OUTPUTTING INFERIOR VEHICLES. NO VEHICLE MANUFACTURED IN 2006 SHOULD NEED THREE NEW RADIATORS WITHIN 3 YEAR AND 70K MILES. STOP LETTING FORD OFF THE HOOK AND GET SERIOUS ABOUT GETTING TO THE BOTTOM OF THEIR ISSUES. JUST DO A SEARCH ON 2006 MERCURY MOUNTAINEER AND YOU WILL CLEARLY SEE THERE ARE ISSUES WITH THE COOLING AS WELL AS THE AUTOMATIC TRANSMISSION. IN FACT, OUR MODEL HAS THE SAME ISSUE THAT OTHERS HAVE REPORTED WITH THE AUTOMATIC TRANSMISSION AND IT WILL SOMETIMES NO MOVES GEARS, SLIP A GEAR, AND TUG LIKE IT IS PULLING OUT OF MUD AT A STOP LIGHT. OPEN A FULL BLOWN INVESTIGATION INTO THEIR LACK OF QUALITY CONTROL AND THE LACK OF PROFESSIONALISM ON THE PART OF THE DEALERSHIPS FOR NOT REPORTING THIS TO CORPORATE. *TR

EACH TIME THEY REPLACED THE RADIATOR WITH A BRAND NEW ONE. I HAVE ALSO CONTACTED FORD / MERCURY TO LOOK FOR ASSISTANCE ON THIS PROBLEM AND WHY THIS IS HAPPENING AND THEY DIRECTED ME BACK TO THE DEALERSHIP. I DO NOT BELIEVE THIS IS NORMAL WEAR AND TEAR ON MY VEHICLE. *TR

THERE IS A BIG PROBLEM WITH THE 2006 MERCURY MOUNTAINEERS AND FORD EXPLORERS WITH THE V6'S RADIATOR. AT VERY LOW MILEAGES THE RADIATOR SEPARATES AT THE SEAMS ON THE SIDE CAUSING A LEAK.
