2009 Mercury Mariner Powertrain (other) Problems

I have been intermittently losing power steering. The code is B1342. After researching, it looks like Ford is aware of this problem but is unwilling to fix the issue. This fix must be done at a dealership since it is a software issue and going to cost $2,000. Obviously losing power steering when going at fast speeds is incredibly dangerous for myself and others. There is no check engine light that comes on when the issue arises.

I AM GETTING CONTINUAL THROTTLE BODY ERRORS ON MY 2009 MARINER. IT GOES INTO LOW POWER MODE SO I CAN "LIMP HOME". IT HAPPENS MOSTLY ON HIGHWAYS WHEN I NEED TO "PUNCH IT" AND GET ALOT OF ACCELERATION.

ON 1/1/2016 I WAS DRIVING ON 495 W IN QUEENS, NY HEADING BACK TO MANHATTAN WHERE I LIVE. OUT OF NOWHERE THE CAR BEGAN JERKING, A WRENCH LIGHT ON THE DASH PANEL CAME ON (WHICH I NEVER SAW BEFORE) AND I COULD TELL THE CAR WAS DECELERATING. I TRIED HITTING THE ACCELERATOR AGAIN, THE CAR WOULD JERK, THE ENGINE WAS REVVING BUT WAS BARELY MOVING. I KNEW I HAD TO PULL OVER AND LUCKILY I WAS ABLE TO NAVIGATE TO THE SHOULDER OF THE ROAD. THIS WAS AN EXTREMELY DANGEROUS SITUATION. I AM A CONFIDENT DRIVER, HOWEVER, A LESS CONFIDENT OR TIMID DRIVER MOST LIKELY WOULD HAVE PANICKED AND GOTTEN INTO A POTENTIALLY SERIOUS COLLISION.

WHILE DRIVING DOWN THE ROAD ANYWHERE FROM 20-55 MPH, THE CAR SEEMS TO STALL OUT AND THE ACCELERATOR NO LONGER WORKS. YOU HAVE TO PULL OVER AND SHUT THE VEHICLE OFF AND IT WILL START AGAIN. SOMETIMES THE SAME PROBLEM WILL OCCUR AGAIN WITHIN SECONDS, MINUTES, OR DAYS LATER.

NORMAL DRIVING WHEN SUDDENLY THERE WAS NO ACCELERATION & THE WRENCH LIGHT CAME ON IN THE DASHBOARD. CAR WAS RUNNING BUT THERE WAS NO ACCELERATION & IDLED ROUGHLY. MECHANIC PUT A DIAGNOSTIC ON IT WHICH READ P2112 THROTTLE CONTROL ACTUATOR SYSTEM STUCK CLOSED. BINDING THROTTLE BODY STUCK CLOSED. THERE WAS NO WARNING AND THE INCIDENT WAS VERY SCARY SINCE I COULD NOT GET OUT OF THE WAY OF TRAFFIC. THE CAR WOULD GO ABOUT 1MPH UNTIL I WAS ABLE TO PULL OFF THE ROAD. WHEN THE CAR WAS LATER SHUT OFF AND RESTARTED, ACCELERATION RETURNED. THIS IS FRIGHTENING AS YOU DO NOT KNOW WHEN IT COULD HAPPEN AND COULD CAUSE A SERIOUS ACCIDENT.

I WAS DRIVING AT 45MPH WHEN ALL OF A SUDDEN, THE CAR STOP RUNNING. I HAD TO PULL OVER AND CUT THE CAR OFF. I STARTED THE CAR AGAIN AND IT WENT ABOUT ONE MILE BEFORE IT CUT OFF AGAIN. THEN A WRENCH SYMBOL CAME ON THE LEFT SIDE DASH BOARD. I DROVE THE CAR HOME AND IT CUT OFF ON ME THREE TIMES BEFORE I COULD GET IT HOME. I LOOK IN MY CAR BOOK TO SEE WHAT THE WRENCH SYMBOL MEANS AND IT SAYS THAT IT IS THE THROTTLE CONTROL/POWERTRAIN. *TR

I WAS TRAVELING DOWN THE INTERSTATE AT APPROX. 70 MPH WHEN SUDDENLY, I FELT A JOLT. AT THIS TIME, I LOST POWER UPON DEPRESSING THE PEDAL. I SLOWLY MOVED TO THE EMERGENCY LANE AND STOP THE VEHICLE. A WRENCH TOOL ILLUMINATED ON THE INSTRUMENT PANEL. I THEN TURNED THE VEHICLE OFF. I WAS ABLE TO RESTART THE VEHICLE. AS I PROCEEDED TO CONTINUE ON MY ROUTE, AS I WAS ACCELERATING, APPROX. 25 - 30 MPH, THE INCIDENT REPEATED IF SELF. THIS OCCURRED ABOUT 4 TIMES BEFORE I REALIZED THAT I COULD ONLY DRIVE ABOUT 15 - 20 MPH IN ORDER TO KEEP THIS CONDITION FROM OCCURRING AGAIN. I WAS ONLY ABOUT 4 MILES FROM HOME, SO I PROCEEDED TO DRIVE HOME VERY SLOWLY. *TR

MY CAR 2009 MERCURY MARINER PREMIER, HAS BEEN SLIPPING (TACH GOES UP BUT MY SPEED DOES NOT) SINCE I BOUGHT THE CAR 2-3 YEARS AGO. THERE IS NOW ABOUT 56,000 MILES ON THE CAR. IT HAS BEEN A COLD WINTER, AND WHEN I START THE CAR AND IT IS COLD, I HAVE BEEN SEEING A LITTLE POOL OF OIL LIKE SUBSTANCE, AND WHEN I BACK UP, THERE IS A LINE OF IT. IT THEN SEEMS TO STABILIZE AND STOP. ONE DAY I WAS USING THE CAR COLD, AND THE TACK WENT UP, BUT I COULDN'T GO ANY FASTER, OR UPSHIFT. I TOOK IT TO THE GARAGE, AND THEY SAID: 6F35 TRANSMISSION - FLUID LEAK - SEAL - LEFT SIDE HALFSHAFT. THE GARAGE POINTED OUT THAT THIS IS AN ONGOING PROBLEM WITH MY YEAR MERCURY MARINER, AND ALSO THE FUSION, MILAN, AND ESCAPE. THE GARAGE SAID THERE WILL PROBABLY BE A RECALL ON THIS PROBLEM. I CAN MAKE A COPY OF THE BILL AND SEND IT. THIS IS A DANGEROUS PROBLEM, AND THE WHEEL COULD FALL OFF. PLEASE LET ME KNOW IF I CAN BE COMPENSATED FOR THIS ONGOEING PROBLEM WITH MY FORD MERCURY MARINER, AND OTHER FORD MODELS.

I WAS DRIVING MY 2009 MERCURY MARINER AND SUDDENLY LOST THE ABILITY TO ACCELERATE. A WRENCH LIGHT ILLUMINATED ON MY DASH AND THE ONLY THING I COULD DO WAS COAST TO A STOP. PUSHING THE GAS PEDAL DID NOTHING. I WAS ABLE TO VERY SLOWLY GET THE CAR TO A PARKING LOT (IT MOVED AT AN IDLE SPEED, BUT WOULD NOT ACCELERATE OTHERWISE). WHEN I GOT TO THE PARKING LOT, I TURNED THE CAR OFF. AFTER WAITING A FEW MINUTES, I TURNED THE CAR BACK ON AND IT SEEMED FINE. I TOOK IT TO A FORD DEALERSHIP AND THEY DIAGNOSED IT AS BEING A PROBLEM WITH THE THROTTLE BODY, WHICH THEY ENDED UP REPLACING. THIS ISSUE OCCURRED ON 12/10/2013 ON A 2009 MERCURY MARINER THAT I PURCHASED NEW IN NOVEMBER OF 2008. IT HAD APPROXIMATELY 69,000 MILES ON IT WHEN THE INCIDENT OCCURRED. I WAS DRIVING AT A SPEED OF ABOUT 40 MPH WHEN IT HAPPENED. IN SEARCHING THE INTERNET, I FOUND THAT THIS IS A VERY COMMON PROBLEM. THERE ARE NUMEROUS NEWS REPORTS, FORUM AND BLOG POSTINGS, AND YOUTUBE VIDEOS OF PEOPLE EXPERIENCING THE SAME PROBLEM WITH THE THROTTLE BODY ON THEIR ESCAPES AND MARINERS. I ALSO FEEL THAT IT IS A SAFETY ISSUE. HAD I BEEN ON THE HIGHWAY WHEN THIS OCCURRED, I VERY LIKELY WOULD'VE CAUSED AN ACCIDENT. (I WAS ACTUALLY JUST ABOUT TO ENTER THE HIGHWAY WHEN THIS INCIDENT OCCURRED.) *TR

THE 2009 MERCURY MARINER HAS AN ISSUE THAT OCCURS WHILE OPERATING THE VEHICLE. THE PROBLEM OCCURRED WHEN POWER WAS CUT OFF FROM THE ACCELERATION, THE WRENCH SYMBOL ON THE DASHBOARD ILLUMINATED (WHICH INDICATES A POWERTRAIN/THROTTLE CONTROL PROBLEM), AND I WAS ONLY ABLE TO COAST THE VEHICLE TO PARK. THE VEHICLE NEVER GAVE ANY INDICATION THAT THERE WAS A PROBLEM UNTIL THE WRENCH LIT UP AND THE ACCELERATOR STOPPED WORKING. IT STARTED A WEEK AGO AND HAS HAPPENED A TOTAL OF 3 TIMES SINCE (WITH MINIMAL DRIVING). ONCE THE PROBLEM HAPPENS AND I STOP THE CAR, I AM ABLE TO PUT IT IN PARK, TURN THE CAR OFF, START IT BACK UP, AND DRIVE AGAIN LIKE NOTHING HAPPENED. THIS IS A VERY UNUSUAL PROBLEM AND LOOKING ONLINE, I SEE IT MAY BE A COMMON ONE. *TR

THE VEHICLE HAS STALLED WHILE IN MOTION 6 TIMES NOW, WHILE STOPPED 3 TIMES. STALLED ONCE WHILE DRIVING UPWARDS OF 40 MPH. I HAD TO STOP IN THE MIDDLE OF THE STREET, PUT EMERGENCY BLINKERS ON, AND RESTART THE CAR. VEHICLE SEEMS TO SPONTANEOUSLY FALTER IN ACCELERATION AND LOSES POWER. TURNING OFF IGNITION AND RESTARTING ENGINE FIXES THE PROBLEM BUT IT WILL THEN REOCCUR AT AN UNKNOWN TIME. SOME INCIDENCES HAVE BEEN IN THE SAME DAY, OTHERS HAVE BEEN UP TO A WEEK APART. *JB

THIS ACTUALLY FIRST OCCURRED ON FRIDAY. I WAS TRAVELING ON THE THRUWAY AT ABOUT 65MPH WHEN THE CAR FELT ALMOST LIKE IT DOWNSHIFTED AND THEN I TOTALLY LOST ACCELERATION AND THE WRENCH LIGHT APPEARED ON THE DASH. I LIMPED TO THE SIDE OF THE ROAD AND THE CAR JERKED AND SPUTTERED BEFORE I SHUT IT OFF. AFTER A FEW MINUTES I RESTARTED THE VEHICLE AND IT SOUNDED LIKE IT WAS FLOODED AT FIRST THEN IT TURNED OVER NORMALLY. I WAS AN HOUR FROM HOME AND MADE IT BACK WITHOUT FURTHER INCIDENT. I TOOK IT TO THE DEALER THE NEXT MORNING AND IT DID NOT SHOW ANY CODES. THEY SUGGESTED I REPLACE THE PURGE VALVE, AND AS I HAD A BUSY WEEK OF WORK RELATED TRAVEL SCHEDULED I WENT AHEAD AND HAD THEM DO IT FOR $120. BETTER SAFE THAN SORRY. RIGHT? TODAY I GET AN HOUR FROM HOME AND IT HAPPENS AGAIN. I CALL MY DEALER AND THEY SUGGEST I FIND THE CLOSEST FORD DEALER AND TAKE IT THERE IMMEDIATELY. CLOSEST FORD DEALER COULDN'T TAKE ME FOR 2 WEEKS!! I WAS AN HOUR FROM MY DESTINATION, SO I DECIDED TO CHANCE IT. I DROVE ABOUT 20 MINUTES AND IT HAPPENED AGAIN. SAME EXACT SCENARIO. I STARTED IT AGAIN, GOT BACK ON THE ROAD AND DROVE 10 MINUTES AND AGAIN, EXCEPT THIS TIME THE ENGINE LIGHT ALSO CAME ON. I CALLED ROADSIDE ASSISTANCE AND WAS TOWED TO A GARAGE. I AM 2 1/2 HOURS FROM HOME AND DRIVING A RENTAL. GARAGE WILL DIAGNOSE AND HOPEFULLY FIX TOMORROW. SERVICE TECH SAID IF HE HAD TO DIAGNOSE WITHOUT A CODE HE WOULD SAY THROTTLE BODY! IT ALSO SOUNDS LIKE THIS IS NOT COVERED BY MY 5 YEAR/60K WARRANTY EITHER. WITH ALL OF THE SIMILAR STORIES I HAVE READ ONLINE FORD NEEDS TO BE FORCED TO DO A RECALL AND REIMBURSE US ALL FOR OUR EXPENSES. *TR
