2010 MERCURY MARINER Engine Problems

TL* THE CONTACT OWNS A 2010 MERCURY MARINER. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 45 MPH, THERE WAS A SUDDEN LOSS OF POWER AS THE WRENCH WARNING ICON ILLUMINATED. THE VEHICLE WAS TOWED TO A DEALER WHERE IT WAS DIAGNOSED THAT THE ELECTRONIC THROTTLE BODY NEEDED TO BE REPLACED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE VEHICLE WAS REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 58,849 AND THE CURRENT MILEAGE WAS 59,000. *TR

HAD PREVIOUSLY HAD THE DEALER LOOK INTO WHAT I THOUGHT WAS ISSUE WITH TRANSMISSION AND GEARS SLIPPING BACK IN 2012. THEY INDICATED THERE WAS A BULLETIN, WHICH I BELIEVE WAS ON A COMPUTER ISSUE, AND THAT THE TECH MADE SOME ADJUSTMENTS. THAT SEEMED TO ADDRESS THE ISSUE FOR A WHILE. IT HAD BEEN ACTING UP AGAIN, AND NOT QUITE THE SAME AS PREVIOUSLY, WITH MORE STALLING OUT AND NOT ACCELERATING AND THEN SUDDENLY JUMPING A LITTLE. ASKED DEALER TO LOOK INTO SITUATION AGAIN ON VISIT ON MAY 30TH. TECHS FOUND NOTHING WRONG. WAS DRIVING HOME ON INTERSTATE ON EVENING OF JUNE 7TH WHEN IT FELT LIKE THE ENGINE HAD LOST POWER. I WAS DRIVING 60 MPH, BUT I WAS ABLE TO PULL OFF TO A WIDE SHOULDER AREA. THE ORANGE WRENCH LIGHT CAME ON. I TURNED OFF CAR AND LET IT SIT FOR A COUPLE OF MINUTES. IT STARTED UP...

A YEAR AGO IN JULY OF 2012 NOT SURE THE APPROXIMATE DATE, I WAS ON MY WAY TO WORK AND ALL OF A SUDDEN EVERYTHING JUST CUT OFF. I'M IN THE MIDDLE OF THE ROAD, ACCELERATOR TO THE FLOOR AND NOTHING. I TOOK THE CAR TO THE DEALERSHIP SAME DAY AND THEY HAD IT ALL DAY LONG AND COULDN'T FIGURE OUT WHAT CAUSED THE SHORT AND SENT ME ON MY WAY. NOW PRESENT DAY WHICH IS A BOUT A YEAR LATER I TAKE MY CAR IN FOR A SIMPLE SAFETY INSPECTION, WAIT 10 MINUTES FOR THE PORTER TO BRING ME MY CAR TO FIND OUT ITS IDLING AND THE ACCELERATOR IS TO THE FLOOR AND ITS NOT MOVING. THE GENTLEMEN COMES IN AND TELLS ME ITS MY THROTTLE BODY GOING OUT ON THE CAR, HE TOLD ME THIS HAS HAPPENED TO SEVERAL PEOPLE AND THE PART IS ON BACK ORDER....

THE CAR LOST ALL POWER WHILE I WAS DRIVING ON THE INTERSTATE AT 65 MPH. I WAS ABLE TO STEER IT TO THE SIDE OF THE ROAD, AND TO RESTART IT. THE SAME THING HAPPENED IN 3 MILES AND THEN AGAIN IN 1 MILE. IT WAS OKAY FOR THE NEXT 3 MONTHS. THEN I TRIED TO PASS A TRACTOR AND MY CAR STALLED. I GOT IT TO THE SIDE OF THE ROAD AND WAS ABLE TO LIMP INTO A FORD SERVICE CENTER WHERE THEY DIAGNOSED A " THROTTLE BODY FAILURE". I AM WAITING ON A PART BACK ORDER TO GET IT FIXED! *TR

MY WIFE WAS DRIVING DOWN THE STREET IN OUR MERCURY MARINER WHEN IT SUDDENLY WENT FROM 30 TO 0 MPH FOR NO REASON. HER FOOT WAS ON THE ACCELERATOR WHEN IT SUDDENLY SLOWED TO A STOP, RIGHT IN THE MIDDLE OF THE ROAD. WHEN SHE TRIED TO DRIVE IT AGAIN THE POWERTRAIN ALARM WAS ON SO WE HAD IT TOWED TO THE DEALER. FORD MECHANICS FOUND IT TO BE AN INTERNAL SHORT IN THE THROTTLE BODY AND REPLACED IT. UNBELIEVABLY, WE HAD TO PAY $342.47, AFTER FORD REFUSED TO DO THE REPLACEMENT OF AN INTEGRAL PART OF THE ENGINE EVEN THOUGH THE POWERTRAIN WARRANTY WAS STILL IN EFFECT AND IT WAS A POWERTRAIN ALARM. NOT ONLY DO I BELIEVE THIS REPAIR SHOULD HAVE BEEN PAID BY FORD UNDER THE WARRANTY, BUT I BELIEVE WE WERE FORCED TO CORRECT A DANGEROUS DEFECT THAT SHOULD HAVE HAD A RECALL, AS MANY OTHERS...

SEVERAL TIMES, WHILE DRIVING VEHICLE, ENGINE SUDDENLY LOST POWER AND THE CHECK ENGINE LIGHT CAME ON SOON AFTERWARD. AT TIMES I WAS DRIVING AT HIGHWAY SPEEDS, AND AT TIMES SLOWER--THE LAST TIME BEFORE SERVICE WAS APPROX. 40 MPH. HAD TO PULL OVER SEVERAL TIMES TO THE SIDE OF THE ROAD, STOP THE ENGINE, THEN RESTART AND TRY TO CONTINUE DRIVING. AFTER SEVERAL MORE LOSSES OF COMPRESSION AND POWER, RETURNED HOME AND TOOK THE VEHICLE IN FOR SERVICE TO THE DEALERSHIP WHERE IT WAS PURCHASED. THEY RAN DIAGNOSTICS, BUT WERE UNABLE TO DUPLICATE THE PROBLEM. PROBLEM RECURRED SEVERAL TIMES AFTERWARD, AND WITH THE CHECK ENGINE LIGHT STILL ON, RETURNED FOR SERVICE ON 4/02/12, WHERE THE DIAGNOSTICS CONFIRMED A PROBLEM WITH THE THROTTLE BODY. IT WAS REPLACED AND THERE HAVE BEEN NO PROBLEMS SINCE THEN. I HAD TO SPEND THE FOLLOWING AMOUNTS FOR SERVICE: DIAGNOSTICS ON 3/30/12: $59. ACTUAL REPAIR ON 4/02/12:...

2010 MERCURY MARINER. CONSUMER WRITES IN REGARDS TO VEHICLE HESITATION INTERMITTENTLY AT VARIOUS SPEEDS. *SMD THE CONSUMER STATED SHE BEGAN NOTICING THE PROBLEM IN 2011, AFTER A 2010 UPDATE OF THE TRANSMISSION SOFTWARE IN A FACTORY RECALL. IN ADDITION TO THE HESITATION WHEN TRYING TO ACCELERATE, THERE WERE ALSO A FEW INSTANCES WHERE THE CRUISE CONTROL SEEMED TO EITHER SURGE OR BACK DOWN, AS IF IT DIDN'T KNOW QUITE HOW TO RESPOND, USUALLY, BUT NOT ALWAYS, WHEN ON A SLIGHT INCLINE. THE CONSUMER STATED ON ONE OCCASION, WHEN THE VEHICLE WAS IN PARK, WITH THE MOTOR IDLING, SHE WAS UNABLE TO GET THE VEHICLE TO GO INTO TO GEAR ON THE FIRST ATTEMPT, WHEN IT DID SHIFT, IT SHIFTED VERY HARD AND NOISILY INTO GEAR ON THE 2ND ATTEMPT. ALSO, THE VEHICLE WOULD SHIFT ROUGH IN LOWER GEARS, TYPICALLY FROM AS TOP OR ACCELERATING AFTER SLOWING TO ALMOST A STOP....

ENGINE STALLED WHILE DRIVING AT HIGHWAY SPEED, STARTED SURGING, RUNNING VERY ROUGH AND WOULD NOT GO ANY FASTER THAN ABOUT 15 MPH. THE VEHICLE WAS STOPPED AND SHUT OFF. AFTER A FEW MINUTES THE VEHICLE WAS STARTED AND SEEMED TO RUN NORMALLY. THE VEHICLE RAN NORMALLY UNTIL 10/05/2012 WHEN IT STALLED AND RAN VERY ROUGH AGAIN. AT THIS TIME THE VEHICLE WAS BEING DRIVEN TO THE LOCAL DEALER FOR A CHECK. WHILE WAITING FOR A CALL BACK FROM THE DEALER THE VEHICLE WAS RESTARTED AND SEEM TO RUN NORMALLY AGAIN. AFTER TALKING TO THE SERVICE MGR., IT WAS LEARNED THAT THE PROBLEM MOST LIKELY WAS THE THROTTLE BODY AND IT WOULD NOT BE UNDER WARRANTY. AT THIS TIME IT WAS DECIDED TO TAKE THE VEHICLE TO A LOCAL SHOP THAT WE WERE VERY PLEASED WITH FOR PAST SERVICE FOR OTHER VEHICLES WITHIN OUR FAMILY. THE LOCAL SHOP ORDERED AND INSTALLED...
