2009 Mercury Mariner Electrical System Problems

The contact owns a 2009 Mercury Mariner. The contact stated that the key was hard to insert into the ignition switch. The power steering assist fault message was displayed. The vehicle was taken to an independent mechanic and the contact was informed that the failure was due to the ignition housing. The contact called the local dealer who informed her the power steering was repaired in 2014 under NHTSA Campaign Number 14V284000 (Steering). The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 198,725.

My power steering assist is not functioning this is part of a current recall that apparently my car is not included in even though it was a recall for mercury mariners 06-10 and I drive an 09.

REAR HATCH WILL NOT OPEN BECAUSE ELECTRIC ACTUATOR HAS FAILED AGAIN, THEREFORE THE SPARE TIRE CANNOT BE ACCESSED ON THE SIDE OF THE ROAD. IT'S BEEN REPLACED ONCE ALREADY. THIS IS A OBVIOUS SAFETY ISSUE.

WHILE TRAVELING APPROXIMATELY 35 MPH, DRIVING IN A STRAIGHT LINE ON A CITY STREET IN TRAFFIC, THE ABS ABRUPTLY APPLIED THE BRAKES - HARD! THE ABS LIGHT CAME ON AND A "CHECK BRAKE SYSTEM" WARNING MESSAGE WAS DISPLAYED. ALSO, THE ELECTRICAL SYSTEM SHUT DOWN AND THE ENGINE LOST POWER. AFTER ABOUT 5 SECONDS, POWER WAS RESTORED AND VEHICLE WAS ABLE TO PROCEED. THIS OCCURRED APPROXIMATELY 8 TIMES OVER A TWO MILE DISTANCE. DURING THE LAST 4 TIMES, THE ENGINE DIED, LOST POWER COMPLETELY, AND NEEDED TO BE TURNED OFF AND RESTARTED TO CONTINUE. THIS FAILURE WAS A DANGEROUS SAFETY HAZARD. VEHICLE WAS TOWED TO ALBUQUERQUE LINCOLN VOLVO. THE PROBLEM WAS DIAGNOSED AS A FAILED ABS MODULE, 9L8Z. THE DEALER REPLACED THE ABS MODULE WITH A FAULTLY MODULE. A SECOND ABS MODULE WAS INSTALLED AND THE VEHICLE WAS DEEMED REPAIRED. THE DEALER DID NOT RETURN THE DEFECTIVE PART FOR ANALYSIS.

WHILE IN MOTION THE CAR WILL STALL CAUSING ME TO PULL OFF TO THE SIDE OF THE ROAD, TURN THE CAR OFF, THEN BACK ON IN ORDER FOR IT TO WORK AGAIN. THIS HAPPENS EVERY 10-15 MILES AND ITS REALLY UNSAFE! I BELIEVE IT IS A DEFECTIVE THROTTLE BODY AND NEEDS TO BE FIXED ASAP BEFORE I CAN CONTINUE DRIVING IT.

PROBLEM STARTED IN DECEMBER 2015, AND GOT PROGRESSIVELY WORSE. ENGINE WOULD NOT START WHEN IGNITION SWITCH WAS TURNED TO THE START POSITION. HAD TO MAKE SEVERAL ATTEMPTS AT IT, AND APPLY DOWNWARD FORCE ON THE KEY UNTIL THE NECESSARY CONTACT WAS MADE. ONCE STARTED IT SEEMED TO RUN NORMAL. FORD DEALER DIAGNOSED THE PROBLEM AS A DEFECTIVE "IGNITION LOCK CYLINDER HOUSING". THEY REPLACED IT WITH A NEW ONE, PART NUMBER 9L8Z*3511*A. ENGINE STARTS NORMALLY NOW. TOTAL COST TO ME $527.74.

TL* THE CONTACT OWNS A 2009 MERCURY MARINER. WHILE DRIVING ON AN INCLINE AT AN UNKNOWN SPEED, THE VEHICLE SUDDENLY DECELERATED AND WOULD NOT ACCELERATE WHEN THE ACCELERATOR PEDAL WAS PRESSED. THE SERVICE ENGINE LIGHT ILLUMINATED PRIOR TO THE FAILURE. THE VEHICLE STALLED AND WAS ABLE TO BE RESTARTED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED THAT THE ELECTRONIC THROTTLE CONTROL FAILED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED. THE VIN WAS UNAVAILABLE. THE FAILURE MILEAGE WAS 118,000.

TL*THE CONTACT OWNS A 2009 MERCURY MARINER. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 10 MPH THE OIL AND BATTERY WARNING INDICATORS ILLUMINATED AND THE VEHICLE STALLED. THE VEHICLE RESTARTED BUT THE FAILURE RECURRED ON 2 OTHER OCCASIONS. THE VEHICLE WAS NOT TAKEN TO THE DEALER. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. ALSO, THE CONTACT STATED THAT THE VEHICLE WOULD NOT START AFTER THE ANTI THEFT DEVICE WARNING INDICATOR INTERMITTENTLY ILLUMINATED. THE VEHICLE WAS NOT TAKEN TO THE DEALER. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND ADVISED THE CONTACT TO HAVE THE VEHICLE TOWED TO THE DEALER TO HAVE THE COMPUTER REPROGRAMMED. THE APPROXIMATE FAILURE MILEAGE WAS 87,000. UPDATED 4/21/15*CN

FAN BLOWER MOTOR ONLY WORKED ON 3RD AND 4TH SETTING. THE BLOWER MOTOR RESISTOR ASSEMBLY (PART NO. 8G1Z*19A706*A) WAS DIAGNOSED AND REPLACED BY DEALER. *TR

MY MERCURY MARINER 2009 HAS HAD ISSUES FOR THE PAST YEAR IN REGARDS TO THE VEHICLE UNEXPECTEDLY GOES INTO "LIMP HOME MODE" AT REDUCED POWER, LIKE WHILE SITTING AT TRAFFIC LIGHT OR STOP SIGN. ALSO, THE WRENCH LIGHT WILL GO ON WHILE DRIVING AND I LOSE ACCELERATION POWER. I CAN PUSH THE GAS PEDAL DOWN AND NOTHING HAPPENS, THE ENGINE IS STILL ON BUT NO ACCELERATION POWER. I WILL COAST UNTIL I CAN GET TO A SAFE SPOT TO HAVE TO POWER IT OFF AND THEN RESTART IT. THIS IS VERY DANGEROUS WHILE DRIVING IN RUSH HOUR BACK AND FORTH TO WORK EACH DAY. THE CAR LAGS WHEN ACCELERATING AND ALSO PUMPS WHILE WHEN COMING TO A STOP. I DO NOT FEEL SAFE IN THE CAR AND WISH I HAD NEVER BOUGHT IT. I CAN'T EVEN MAKE A TRIP TO THE STORE WITHOUT WORRYING ABOUT THE WRENCH COMING ON OR IT GOING INTO LIMP MODE. *TR

WHILE DRIVING THE VEHICLE'S DASH LIGHTS AND HEAD LAMPS GO BLACK FOR 2-5 MINUTES BEFORE COMING BACK ON. MY CAR WAS TAKEN TO THE DEALER MULTIPLE TIMES AND WAS UNABLE TO BE DIAGNOSED. I ALSO CONTACTED FORD DIRECTLY AS THIS PROBLEM POSES A HAZARD DURING NIGHT DRIVING. TO DATE THERE HAS BEEN NO RESOLUTION. WHILE DRIVING THE VEHICLE WILL LOSE ALL ACCELERATION, THIS ISSUE HAPPENS WHILE DRIVING DOWN THE ROAD POSING A HAZARD AS YOU HAVE TO TURN THE VEHICLE OFF AN ON AGAIN TO REGAIN CONTROL. *TR

THIS IS THE FOURTH TIME SINCE PURCHASING THE CAR AT CARMAX IN OCTOBER 2012 THAT THE CAR HAS "SHUT OFF" WITHOUT WARNING AT LOW SPEED WHEN CLOSE TO PARKING OR DRIVING SLOW--WITHOUT RHYME NOR REASON--I HAD IT DIAGNOSED AT CARMAX TO NO AVAIL, THEN CHEROKEE FORD TO NO AVAIL (WHERE I PURCHASED A NEW BATTERY), THEN AT CHRISTIAN BROTHERS AUTO WHERE THEY REPLACED THE SPARK PLUGS AND COIL.( I HAVE AN EXTENDED WARRANTY SO MY COST WAS 200DOLLARS) THE PROBLEM CONTINUES. I HAVE DONE RESEARCH AND SEE THE THROTTLE BODY IS MOST LIKELY THE CULPRIT AND A SAFETY ALERT IS ON THE WEB FROM CONSUMER REPORT AND FORD FORUM AND NORTH CAROLINA SAFETY BOARD---I AM HAVING THE TROTTLE BODY REPLACED AT MY EXPENSE--MY DAUGHTER DRIVES THIS VEHICLE AND I WANT IT SAFE! APPARENTLY THIS INVOLVES THIS MODEL 2009-2012. *TR

AFTER GOING THROUGH A CAR WASH, I RECEIVED A WARNING ON THE DASH THAT THERE WAS A PROBLEM AND THAT I SHOULD FIND A SAFE PLACE TO STOP. WHEN I RETURNED HOME AND STOPPED THE CAR IT WOULD NOT RESTART. THE SAME THING HAPPENED ON FEBRUARY 16,2013, AGAIN AFTER GOING THROUGH A CAR WASH. THE LOCAL DEALER WAS ABLE TO GET THE VEHICLE RUNNING, BUT WOULD NOT SAY THAT IT WAS REPAIRED. *TR
