I PURCHASED A 2005 MERCURY MARINER IN MARCH OF 2007, THIS VEHICLE HAD 11,000 MILES ON IT. IN JUNE OF 2009, I BEGIN HEARING RATTLING NOISE IN THE ENGINE AND THE GEARS BEGIN OPERATING VERY POORLY. HAD AN AUTO SHOP CHECK OUT WHAT THE PROBLEM COULD BE IN JUNE OF 2009, AND WAS TOLD MY TRANSMISSION NEEDED REPAIR. I STOPPED DRIVING THE VEHICLE AND BEGIN USING A RENTAL CAR UNTIL I COULD PUT THE MONEY TOGETHER FOR THE REPAIR, WHICH I WAS QUOTED OVER $2100.00. I CONTACTED FORD TO INQUIRE ABOUT WHY I'M HAVING THIS PROBLEM AT 40,989 MILES, FORD CLAIMED THEY HAD NO REPORTED CASES OF MY MECHANICAL PROBLEM AND THAT I NEEDED TO GET IT TO THE DEALER TO BE CHECKED OUT. I WAS INFORMED I WOULD BE RESPONSIBLE FOR ALL CHARGES, REPAIRS, TOWING AND RENTAL CAR EXPENSES, SINCE THE 36,000 MILES WARRANTY AND 3 YEARS HAD EXPIRED. I MADE ARRANGEMENTS FOR MY CAR TO BE REPAIRED BY THE FIRST AUTO SHOP, AND THE TRANSMISSION WAS REBUILT, TOTAL COAST, NOT INCLUDING RENTAL CAR CAME TO $2237.50. JULY 16, 2011 I WAS TRAVELING APPROX. 30 MILES AND MY OD OFF LIGHT BEGIN FLASHING, MADE A STOP AT A CONVENIENT STORE, RESTARTED THE CAR AND THE OD OFF LIGHT HAD STOPPED FLASHING. WHILE CONTINUING TO TRAVEL APPROX. ANOTHER 30 MILES, OD OFF LIGHT BEGIN FLASHING AGAIN, APPROX. 20 MINUTES LATER THE CHECK ENGINE LIGHT CAME ON. THERE WERE NO SIGNS OF OVER HEATING, NO STRANGE SMELLS OF ANY SORT, THE VEHICLE CONTINUED TO RUN AS NORMAL. ONCE I MADE MY FINAL DESIGNATION, THE VEHICLE APPEARED TO BE FINE AND NORMAL, STILL NO SIGNS OF OVER HEATING OR NO STRANGE SMELLS. WHILE TRAVELING BACK APPROX. 45 MILES, THE OD OFF LIGHT BEGIN FLASHING, NO SIGNS OF OVER HEATING, NO STRANGE SMELLS. APPROX. ANOTHER 30 MILES, THE CHECK ENGINE LIGHT CAME ON. CHECK ENGINE LIGHT REMAINED ON, I LOCATED A COUPON FOR A FREE SCAN WITH AAMCO, WHICH FOUND THAT MY TRANSMISSION NEED TO BE REPAIRED, THE TRANSMISSION FLUID WAS DRAINED AND WAS BURNT. TOTAL COST FOR THIS REPAIR, NOT INCLUDING RENTAL CAR IS $2290.00, MILEAGE IS AT 59,900. *TR
GAS MILEAGE HAS SUDDENLY AND MARKEDLY PLUMMETED ON HIGHWAY DRIVING. AIR FILTER REPLACED - NO CHANGE. THERE HAS BEEN NO CHANGE IN DRIVING PATTERNS. IT HAS GONE FROM AROUND 20 HWY TO AROUND 10 HWY OUT OF THE BLUE - NO ENGINE/TRANNY/BRAKES ISSUES OR ANYTHING LIKE THAT. NOT A CLUE. *TR

2005 MERCURY MARINER. VEHICLE RUNNING JUST FINE, EXCEPT STARTING SLUGGISH. NEEDED NEW BATTERY. I CHANGED IT. RIGHT AWAY IT BEGAN TO SHIFT ROUGH ON 3 SHIFT (AUTOMATIC). READ MANUAL AND IT STATED TO GIVE TIME FOR COMPUTER TO RESET TO DRIVE CONDITIONS. AFTER 3 WEEKS I SET UP APPOINTMENT WITH DEALERSHIP. THEY CHARGED $119.00, AND STATED THAT THEY UPDATED THE COMPUTER, BUT IT STILL DID SAME THING. THEY INFORMED ME THEY CALLED FORD, AND WAS TOLD TO REPLACE THE TRANSMISSION FOR $3500. THE TECHNICIAN DID NOT SEEM CONVINCED OF THAT, AND SAID FLUID WAS FINE AND DID NOT SMELL BURNT. SAID TO DRIVE LONGER. I HAVE WRITTEN TO FORD TO NO AVAIL. THEY ALSO STATED THE REASON IT DID NOT DO IT WITH THE OLD BATTERY WAS DUE TO THE COMPUTER COVERING THE ROUGH SHIFT. I TALKED TO A TRANSMISSION EXPERT. HE JUST COULD NOT SEE THAT BEING POSSIBLE. *TR

THE CAR STOPPED RUNNING AS I EXITED THE INTERSTATE OFF RAMP. THIS WAS IN HIGH TRAFFIC WITH CARS BEHIND ME. I WAS ABLE TO GET THE CAR RESTARTED AND COASTED TO THE SIDE OF THE ROAD. A TOW TRUCK TOOK ME TO A FORD DEALER, WHERE IT WAS STATED THE TORQUE CONVERTER HAD FAILED. THE FORD DEALER TOLD ME THAT A NEW "CODE" NUMBER HAD BEEN ISSUED BECAUSE THERE WERE SO MANY PROBLEMS FOR FORD ESCAPE AND MERCURY MARINER FROM 2003-2008. MY VEHICLE IS A 2005 MERCURY MARINER. I HAD NO PREVIOUS INDICATIONS THAT THIS WOULD FAIL AND WAS TRAVELING OUT OF STATE. THE COST WAS $1800 AND THE DEALER STATED THAT FORD AND MERCURY WERE NOT DOING ANYTHING TO RESOLVE THIS OTHER THAN ISSUE AN INTERNAL NOTICE TO ALL DEALERS. I FEEL A RECALL SHOULD BE ISSUED AND MY COSTS REFUNDED, THEY ARE OBVIOUSLY AWARE OF THIS ISSUE. *TR

EVER SINCE THEN MY VEHICLE HAS CONTINUED TO STALL ONCE PLACED INTO GEAR AND COMING TO A STOP AT PERIODIC TIMES. I FIND MY VEHICLE UNSAFE TO DRIVE, DUE TO IT HAPPENING OUT OF NOWHERE AND AT INTERSECTIONS.

215V606000 · Power Train:automatic Transmission:gear Position Indication (prndl); Power Train:automatic Transmission:lever And Linkage:floor Shift
Sep 29, 2015
Ford Motor Company (Ford) is recalling certain model year 2001-2008 Ford Escape and Mercury Mariner vehicles manufactured March 31, 2001, to September 1, 2009. The affected vehicles are equipped with either a 2.3L or 3.0L engine and have had their CD4E transmission replaced with remanufactured one that was rebuilt between June 11, 2015 through July 15, 2015. These service repair part transmissions have a shift lever bolt that may not be properly tightened. As a result, the shift control lever could disengage from the transmission without warning.
Consequence & remedy
Consequence: If the shift lever disengages from the transmission, a driver may be unable to shift gear positions and the indicated shift position may not represent the gear position the vehicle is in. Should a disengagement occur while the vehicle is being driven, when the driver goes to stop and park the vehicle, the gear selection indicator may show that the transmission is in the "PARK" position, but the vehicle transmission may not actually be in the "PARK" gear position. If the vehicle is not in the "PARK" position there is a risk the vehicle will roll away as the driver and other occupants exit the vehicle or anytime thereafter. A vehicle rollaway increases the risk of injury to exiting occupants and bystanders.
Remedy: Ford will notify owners, and dealers will inspect the transmissions and either tighten the manual shift lever bolt or replace the manual shift lever assembly. These repairs will be performed free of charge. The recall began on October 23, 2015. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 15S28.
