started losing power ,did not want to go pas 30 miles per hr ,then it ramed up and came to a stop with no acceleration ,i shut it off then start it again and was able to get home at a low rate of speed while continuing to have these problems, another day while far away from home the engine rammed up again minimizing my speed as the transmission was slipping and not go fast then my O/D over drive went on flashing a light ,while the engine kept steady at 20-30 miles per hour while accelerating increasing no speed ,now my SUV will not run wright, it will kick into gear at times constantly and cause problems driving safely ,this is a common problem I'm hearing and reading in the internet with the ford/ mercury mountaineer the manufactory does not want to accept responsibility with this problem ..... this is clear a RECALL ISSUE that needs to be addressed before someone gets killed on the highway by getting rammed by a semi-truck which it almost happened to me !!!! a multi-million dollar law suit is in order if they do not acknowledge and fix this problem

THE PLASTIC THAT HOLD THE VISOR ARM ON PLACE CRUMBLES. BOTH SIDES WERE AFFECTED. THE OUTER SHIELD PLATES SEEM OK IT'S ONLY THE PIECE THAT I CAN ONLY GUESS, 'STABALIZES' THE VISOR WHEN YOU MOVE IT FROM FRONT TO SIDE OF THE CAR. IT LOOKS LIKE THEY'RE ABOUT $30-$80 EACH TO REPLACE. THIS IS A 3RD HAND VEHICLE HOWEVER THE MILEAGE IS FAIRLY LOW FOR THIS YEAR AT 127,408. THESE ARE NOT PLASTIC PIECES THAT ARE IN THE SUN A LOT, THEY AREN'T AT ALL BUT CRUMBLE LIKE PLASTIC CAN BECAUSE OF SUN EXPOSURE. THERE IS GLUE IN THE PHOTO THAT I PUT ON AS A TEMPORARY FIX BUT IT PEELS OFF EASILY.

TL* THE CONTACT OWNS A 2005 MERCURY MOUNTAINEER EQUIPPED WITH FOUR COOPER DISCOVERER H/T TIRES, SIZE: 245/65R17. THE CONTACT STATED THAT ALL FOUR TIRES RUMBLED AND RODE ROUGHLY INSTEAD OF PROVIDING A SMOOTH, STABLE RIDE WHILE DRIVING AT ANY SPEED. THE VEHICLE WAS TAKEN TO A TIRE FACILITY MORE THAN FIVE TIMES, BUT THE CAUSE OF THE FAILURE COULD NOT BE DETERMINED. THE MANUFACTURER WAS CONTACTED, BUT HAD NOT REQUESTED THAT THE TIRES BE SENT TO THEM FOR TESTING. THE CONTACT WAITED OVER TWO YEARS FOR A RESPONSE FROM THE MANUFACTURER AND DECIDED TO REPLACE THE TIRES ON HIS OWN. ONCE THE TIRES WERE REPLACED, THE RUMBLING STOPPED. THE DOT NUMBER, VIN, AND TIRE AND VEHICLE FAILURE MILEAGE WERE UNKNOWN.

I PURCHASED A USED 2005 MERCURY MOUNTAINEER LAST MONTH, WITH 135,400 MILES, WHILE USING CRUISE CONTROL AND TRAVELING APPROXIMATELY 35 MPH, THE ROAD WENT FROM LEVEL TO A VERY SLIGHT DOWNGRADE. THE CAR THEN JUST SHUT OFF AFTER AUDIBLE WARNING BELL WAS HEARD. NOTICED DASHBOARD LIGHTS WERE ALL LIT AND BATTERY GAGE WAS NORMAL. I LOST POWER STEERING, BRAKES AND OIL PRESSURE. AFTER PULLING SAFELY TO THE SIDE OF THE ROAD, I RESTED FOR 30 SECONDS BEFORE RESTARTING THE CAR, WHICH SUBSEQUENTLY OPERATED NORMALLY. AFTER TAKING IT IN FOR AN OIL CHANGE AND SAFETY CHECK, I WENT ON A 450 MILE WEEKEND TRIP AND HAD NO ISSUES, RESTRICTING CRUISE CONTROL TO HIGHWAY SPEEDS. THE OTHER DAY, I WAS TRAVELING ON A DIFFERENT STRETCH OF LEVEL ROAD IN MY TOWN WHILE USING CRUISE CONTROL AT APPROX. 35 MPH. AFTER HEADING INTO A SLIGHT DOWNGRADE, I AGAIN HEARD THE WARNING BELL, FOLLOWED BY ENGINE SHUT OFF. A "CHECK GAGE" LIGHT CAME ON AND I LOST POWER STEERING, OIL PRESSURE AND BRAKES. THIS TIME, I GENTLY SHIFTED THE CAR INTO NEUTRAL, AND WHILE COASTING AT 15-20 MPH I TURNED THE IGNITION OFF BEFORE RESTARTING WITHOUT ISSUE. THE CAR HAS SUBSEQUENTLY OPERATED NORMALLY, BUT I HAVE NOT ENGAGED THE CRUISE CONTROL AT ANY SPEED.

TL* THE CONTACT OWNS A 2005 MERCURY MOUNTAINEER. UPON INSPECTION, THE CONTACT NOTICED THAT THE REAR PANEL WAS CRACKED. THE CONTACT WAS CONCERNED THAT THE INTEGRITY OF THE REAR WINDOW WAS COMPROMISED DUE TO THE CRACKS. THE VEHICLE WAS TAKEN TO DICK SMITH FORD (9505 E STATE RTE 350, RAYTOWN, MO) WHERE THE CRACKS WERE CONFIRMED. THE DEALER DIAGNOSED THAT ADHESIVE MATERIAL NEEDED TO BE ADDED TO THE CRACKS TO REINFORCE THE PANEL. THE MANUFACTURER STATED THAT IF THE CONTACT WERE TO REPAIR THE FAILURE INDEPENDENTLY, SHE MAY BE REIMBURSED IF A RECALL WERE ISSUED. THE FAILURE MILEAGE WAS APPROXIMATELY 116,354. *TT *TR

ON TWO OCCASIONS THE ENGINE CUT OUT WHILE DRIVING THE CAR, ALL THE ENGINE WARNING LIGHTS CAME ON. ONCE THE CAR WAS SAFELY OFF THE ROAD AND PLACED IN PARK IT WOULD START AND CONTINUE TO OPERATE. THE FORD DEALER SAID THAT THERE WAS NOT FAULT CODE IN THE COMPUTER, THEY COULD NOT DUPLICATE THE FAILURE AND COULD NOT FIND ANY FAULT IN THE ENGINE SYSTEM. FORD SERVICE REPRESENTATIVES SAID I SHOULD GO A DIFFERENT FORD DEALER AND SEE IF THEY COULD SOLVE THE PROBLEM. I FIND SIMILAR ENGINE FAILURES DOCUMENTED ON THE INTERNET FOR THIS GENERATION OF CAR. MORE CURRENT SIMILAR MODEL ARE NOT REPORTED TO HAVE THIS PROBLEM. THUS I ASSUME FORD FOUND AND FIXED THIS PROBLEM. I ASKED THEM TO TELL ME HOW THEY SOLVED THE PROBLEM, THEY SAID THAT WAS NOT POSSIBLE. SO, I HAVE AN OTHERWISE GOOD CAR WHICH I CAN DO USE NOR IN GOOD CONSCIENCE SELL TO SOMEONE ELSE. PLEASE HELP! *TR

SOMETIMES WHEN I'M DRIVING AROUND 35 MPH, THE CAR WILL SEND AN AUDIBLE WARNING SIGNAL, MOST OF THE DASHBOARD LIGHTS COME ON AND THE ENGINE ABRUPTLY SHUTS OFF. IT NEVER HAPPENS WITH MY WIFE WHO IS THE PRIMARY DRIVER OF THIS VEHICLE. THIS BEGAN SHORTLY AFTER PURCHASE AND WAS MENTIONED TO OUR L/M DEALER (BEFORE THEY WENT OUT OF BUSINESS). I JUST MADE THE CORRELATION WITH THE SPEED CONTROL LAST WEEKEND. IN FACT, I CAN DUPLICATE THE ISSUE NOW. THE SHUTOFF OCCURS DURING DECELERATION WHEN SPEED CONTROL IS ENGAGED AROUND 35 MPH. SINCE MY WIFE ONLY USES SPEED CONTROL ON THE INTERSTATE, IT HAS NEVER HAPPENED TO HER.

"TAKATA RECALL" PURCHASED THE VEHICLE WITH 158,000 MILES ON IT. OWNED FOR ONE MONTH. BARELY DRIVING EVEN 12 MILES A DAY AS I HAVE BEEN LAID OFF FROM JOB. VEHICLE WAS PARKED IN DRIVEWAY, SITTING. OPENED THE REAR LIFT GATE TO RETRIEVE GROCERIES AND CLOSED GATE. REAR WINDOW BLEW OUT INTO A MILLION PIECES WITH THE CENTER PIECE THAT IS PLASTIC? TWISTED AS WELL. DID NOTICE CRACK IN PANEL NEAR THE EMBLEM SHORTLY AFTER THE PURCHASE OF VEHICLE AND I THOUGHT THAT THE PRIOR OWNER MAY HAVE BACKED INTO SOMETHING , ALTHOUGH THERE WAS NO DENT OR PAINT MARKED UP NEAR THE CRACK, SO I WAS STUMPED AS TO HOW IT GOT THAT WAY). AFTER INQUIRING ON THE INTERNET, I FOUND SEVERAL COMPLAINTS ABOUT THE LIFT GATE PANEL AND GLASS FALLING OUT. I HAD SEALED THE CRACK WITH CLEAR SILICONE JUST A WEEK AFTER PURCHASING IN ORDER TO KEEP THE WATER OUT OF THE LIFT GATE. DEALER RAN MY VIN AND SAID THERE WAS NO RECALL FOR THIS VEHICLE. I PURCHASED A VEHICLE REPORT THIS MORNING FOR MY VIN AND IT INDICATES THAT THERE WAS A RECALL ON GLASS THAT STATES THE #DOT430 IS DEFECTIVE GLASS. I AM NOT SURE IF THIS IS THE STAMPING ON MY GLASS AS THE DEALERSHIP/BODYSHOP REMOVED THAT PANEL AND THREW OUT THE PANEL IN THE GARBAGE. THEY SEALED THE REAR LIFT GATE WITH PLASTIC WHILE THE INSURANCE ADJUSTER EVALUATES. I KNOW THIS PROBLEM HAS BEEN ONGOING BY ALL THE REPORTS THAT I HAVE READ ONLINE AND SHOULD BE COVERED BY FORD OR WHATEVER MANUFACTURER WHO SUPPLIED PARTS. THIS IS A VERY DANGEROUS ISSUE AND NEEDS TO BE ADDRESSED AND SHOULD NOT BE THE RESPONSIBILITY OF THE OWNER TO FIX. MY INSURANCE COMPANY TOLD ME LAST WEEK THAT I MAY BE RESPONSIBLE SINCE I WAS NOT INVOLVED IN AN CAR ACCIDENT. THIS SHOULD NOT BE MY RESPONSIBILITY TO PAY FOR!

WHILE DRIVING 50 MPH VEHICLE STALLED THREE TIMES. TOOK IT TO A GARAGE, WAS TOLD IT WAS NECESSARY TO HAVE THE VEHICLE WHEN IT STALLED. FOUND ELEVEN (11) SIMILAR COMPLAINTS ON YOUR SITE! PERHAPS THERE IS SOME VALIDITY TO THE COMPLAINTS. ALL PARTS OF THE VEHICLE RELATED TO SAFE DRIVING WERE RENDERED USELESS. SOUNDS LIKE A SAFETY ISSUE TO ME!

I HAD THE CRUISE CONTROL SET ON 30 MPH DRIVING IN A RESIDENTIAL AREA. WITHOUT WARNING, ALL THE LIGHTS ON MY DASH FLASHED, AND MY VEHICLE LOST ALL POWER. VERY SCARY. NO MORE POWER STEERING, NO POWER BRAKES, WHILE COASTING THROUGH A NEIGHBORHOOD. I PUT THE CAR IN NEUTRAL, TURNED THE KEY OFF, BACK ON AGAIN, AND PUT THE CAR BACK IN DRIVE. THAT FIXED THE PROBLEM. THIS IS VERY SCARY AND DANGEROUS!! THIS IS THE THIRD TIME IT HAS HAPPENED TO ME. I AM AFRAID TO USE THE CRUISE CONTROL ON MY CAR NOW :( *TR
