2005 Mercury Mountaineer

This investigation is being closed based on several considerations.By the most inclusive counting of all alleged rollaway incidents (i.e., counting all alleged rollaway incidents and assuming a singular failure mechanism), the incident rate is low, however during EA09-013, ODI identified a number of different failure mechanisms in 180 incidents related to the alleged defect.The highest rate for any particular failure mechanism, the failure of the Automatic Transmission Parking System, was 4.4/100K.The next-highest failure rate was for the BSI System, at 3.4/100K.For all identified failure mechanisms there has been a drastically declining trend including very few incidents occurring in recent years.Accordingly, this investigation is closed.The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist.For additional information regarding this investigation, see the complete closing resume in the document file for EA09-013. The ODI reports cited above can be reviewed at www-odi.nhtsa.dot.gov/owners/SearchNHTSAID under the following identification (ODI) numbers:10168454, 10279630, 10280078.

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.

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.

The Powertrain Control/Emissions Diagnosis (PC/ED) manual has been revised for diagnosing electronic throttle bodies (ETBs). The ETC_ACT and ETC_DSD PIDs should not used to diagnose possible ETB concerns. The IDS has a limited refresh rate when reading these PIDs and cannot display quickly enough to validate a concern. The PCM automatically monitors these inputs more accurately and will set diagnostic trouble codes (DTCs) when appropriate. Using these PIDs for diagnostics will lead to inaccurate results and improper ETB replacements. If a concern is intermittent and no DTCs are present, refer to historical DTCs and the PC/ED, Section 3 No DTCs Present Index chart for further information.

FORD/LINCOLN/MERCURY: IF BATTERY WAS DISCONNECTED OR DEAD, VEHICLES/TRUCKS MAY EXPERIENCE HARD STARTS AND ENGINE IDLE RPM FLUCTUATION AND EXHIBIT DIAGNOSTIC TROUBLE CODES (DTCS) P0505, P0506, P2111 AND P2112. *PE
