My shifter continuously won’t come out of park. Multiple other people with the same kind of vehicle have posted on forums with the same issue. It’s happened weekly for a year or more. I keep getting told there’s a recall on it but can’t find it.

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.

SHORTLY AFTER PURCHASING MY MOUNTAINEER THE ELECTRIC RUNNING BOARD ON THE DRIVER SIDE BEGAN TO MAKE A GRINDING SOUND. BOUGHT FROM A DEALER IN WA STATE AND MOVED TO WI STATE WHERE THE DRIVER SIDE STOPPED AND THE PASSENGER SIDE STOPPED EXTENDING/RETRACTING. MOVED TO NJ AND WE HAD PURCHASED THE VEHICLE EXTENDED WARRANTY. BEGAN TO SOUND LIKE A KNOCKING SOUND WITH LITTLE POWER AND HAD TOWED TO DEALER. THERE THEY FOUND ALL 8 SPARK PLUGS FOULED, DRIVER SIDE HAD 3 EXHAUST MANIFOLD BOLTS LOOSE. PASSENGER SIDE HAD SAME 3 LOOSE, BUT ALSO HAD 2 BROKEN OFF IN EXHAUST MANIFOLD PLUS THE MANIFOLD ITSELF HAD A HAIRLINE CRACK. IN THE END, I PAID ALMOST $2,000 TO HAVE DRIVER AND PASSENGER RUNNING BOARD AND MOTORS REPLACED. THE REAR WINDSHIELD WIPER MOTOR HAD GONE BAD AND WAS REPLACED, THE SPARK PLUGS AND ALL MANIFOLD BOLTS (ALONG WITH BROKEN) WERE ALL REMOVED AND REPLACED.

MOUNTAINEER PREMIER AWD WITH JUST OVER 150,000 MILES. WENT TO RAISE REAR (THIRD ROW) ELECTRICAL SEAT ON DRIVER/LEFT SIDE. MAKES A SLIGHT CLICKING SOUND AND WILL RAISE UP ABOUT 1 INCH, THEN JUST STOPS GOING UP WITH SOUNDS STILL HEARD. FURTHER INVESTIGATION SHOWS A MOTOR IN THE CENTER ALONG A GEAR SHAFT WHICH MUST RAISE THE SEAT. THE MOTOR IS WHIRRING LIKE IT IS FUNCTIONING BUT THE SHAFT DOESN'T MOVE. THERE IS NO WAY TO MANUALLY FULLY RAISE THE SEAT.

BOUGHT USED IN WA STATE AND LIVE IN NJ NOW. AFTER PURCHASSE IT RAINED ONE NIGHT AND NEXT MORNING ENTIRE CENTER CONSOLE, OVERHEAD LIGHTS WERE ALL WET INSIDE. UPON FURTHER INVESTIGATION DETERMINED LEAK WAS SUNROOF. NOTIFIED DEALER AND THEY HAD A GLASS SPECIALIST REMOVE THE ENTIRE ASSEMBLY AND THOROUGHLY CLEAN. REPLACED SEAL WITH NEW ONE AND CLAIMED NO MORE LEAKAGE. A FEW DAYS LATER IT RAINED AGAIN (WA WELL KNOWN FOR ALWAYS RAINING) AND AGAIN THE LEAK WAS PRESENT. THE DEALER'S RESPONSE WAS NOW 'PARK YOUR VEHICLE WITH THE FRONT END DOWNHILL. THERE ARE TINY SLOTS THAT DIRECT THE WATER DOWN THE CORNER PILLARS AND APPARENTLY CLOG EASILY. SO PARKING WITH FRONT END DOWNHILL WILL RELIEVE THE WATER BEFORE IT CAN POOL UP TO LEAK.

THE REAR WINDOW HINGES DISINTEGRATED AND THE REAR WINDOW FELL OFF. WE WERE NOT IN MOTION AND JUST IN LIFTING THE WINDOW IT CRACKED OFF. IN RESEARCHING THERE WAS A RECALL IN 2004 FOR THE SAME EXACT ISSUE FOR THE SAME MAKE/MANUFACTURER . THE PROBLEM HOWEVER WAS NEVER FIXED IN THE YEARS THAT FOLLOWED AND SADLY THERE HAS BEEN NO SUBSEQUENT RECALLS IF I SMALL CHILD WAS BEHIND THE WINDOW THEY COULD HAVE BEEN SERIOUSLY INJURED OR IF THE CAR WAS IN MOTION THE WINDOW COULD HAVE CRACKED AND FALLEN OFF. AFTER CALLING THE FORD MOTOR COMPANY THEY RESPONDED THAT FOR MY MAKE AND MODEL YEAR THE RECALL DOESN'T APPLY BUT TO HOLD ON TO MY RECEIPT JUST IN CASE..... PLEASE SEE ATTACHED PICTURES OF THE HINGES, THE PARTS ALONE COST OVER $150
