I PURCHASED THIS VEHICLE RECENTLY WITH ONLY 40,000 MILES. THE CAR KEEPS STALLING OR DYING AS YOU MAY SAY AS I DRIVE. IT WILL BE OKAY FOR A SHORT PERIOD OF TIME AND THEN JUST DIE RIGHT ON THE HIGHWAY! ONCE IT DIES ONCE, THE CAR WILL CONTINUE TO DO SO OVER AND OVER AGAIN UNTIL THE ENGINE HAS COOLED DOWN. I HAVE THE ENGINE CODES OF P2104, P2111 AND P2135 WITH A REFERE TO P2101. I HAVE BROUGHT IT TO SEVERAL MECHANICS AND PAID WELL OVER $1,000 TO FIX THIS PROBLEM AND IT JUST CONTINUES. I AM AFRAID MY FAMILY MAY ALL DIE! WERE ON 93 RECENTLY HEADING TOWARD BOSTON AND MY CAR DIED RIGHT AT THE INTERSECTION OF 495. I HAD ALL MY CHILDREN IN THE CAR AND IT WOULD NOT RESTART. I HAVE FIXED THE FUEL SYSTEM (ERROR CODE LAST TIME), HAD A COMPLETE TUNE UP, AND THROTTLE SENSOR ETC.

MY 2006 MERCURY MOUNTAINEER WAS LEAKING COOLANT DUE TO A CRACK IN THE RADIATOR. AFTER SEARCHING ONLINE FORUMS, I HAVE LEARNED THAT HAS BEEN A LONG STANDING ISSUE WITH MANY OF THIS VEHICLES OWNERS. UNFORTUNATELY FOR OWNERS, FORD ISSUED A TBS IN 2009 JUST IN TIME FOR MOST OF THE AFFECTED VEHICLES' WARRANTIES TO EXPIRE. SOME OWNERS ARE ON THEIR 3RD OR MORE RADIATOR REPLACEMENT, I AM ONLY ON MY FIRST. I PETITION THAT FORD RECALLS THIS ISSUE BEFORE MYSELF AND OTHERS HAVE TO REPEATEDLY PAY FOR THIS CLEAR DESIGN PROBLEM WITH THEIR HARD OWNED MONEY. THIS PROBLEM ALSO POSES SAFETY RISK TO THE PASSENGERS OPERATING THESE VEHICLES AND TO ANY ANIMALS ATTRACTED TO THE SWEET SMELL OF THE COOLANT FROM AFFECTED VEHICLES WHOSE OWNERS WHO MAY NOT YET KNOW THIS ISSUE OR CANNOT AFFORD TO FIX IT.

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

I HAVE GONE THROUGH 3 RADIATORS SO FAR AND NOW I NEED A 4TH. THIS TIME, THE RADIATOR CAUSED THE PUMPS TO START LEAKING ( WHICH ARE NOT SERVICEABLE) AND EVENTUALLY RUINED MY TRANSMISSION, RENDERING THE TRUCK NON-DRIVABLE. THIS PROBLEM HAS COST ME THOUSANDS OF DOLLAR AND I WANT A RECALL TO START ON THIS PART WITH FORD. *TR

PURCHASED IN JUNE 2009 AND HAVE HAD PROBLEM AFTER PROBLEM. MOUNTAINEER PREMIER AWD. TRANSMISSION ISSUE, FEELS LIKE YOU'RE GETTING HIT FROM BEHIND WHEN COMING TO A STOP. RADIATOR LEAKS. BACK LIFT GATE RANDOMLY OPENS, WON'T LATCH. WHEN IT RAINS, WATER COMES IN THROUGH THE INTERIOR LIGHT MOUNT AND THROUGH DVD PLAYER. SPARK PLUGS NOT EASILY REPLACED, BROKE OFF AND HAD TO BE TOWED TO A SHOP FOR REMOVAL. GAS UNABLE TO BE PUMPED PROPERLY I CAN PUT IN .25 AT A TIME IF I'M LUCKY. IT TAKES 20 MINUTES TO PUMP HALF A TANK OF GAS. I LOVE THE FEATURES THIS VEHICLE HAS BUT THIS HAS BEEN SUCH A HASSLE. *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
