Recent owner complaints
- Hybrid propulsion system
The contact owns a 2007 Mercury Mariner. The contact stated while driving 50 MPH, the engine started to overheat, after which the vehicle lost motive power. The contact was able to pull to the shoulder of the roadway to let the engine cool down. After restarting the vehicle, the vehicle returned to normal functionality; however, the failure had since become a regular occurrence. The engine overheated warning light was illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 14V526000 (Hybrid Propulsion System) but the VIN was not included. The…
- Service brakes
TL* THE CONTACT OWNS A 2007 MERCURY MARINER HYBRID. WHILE DRIVING APPROXIMATELY 60 MPH, THE BRAKE PEDAL TRAVELED TO THE FLOORBOARD BEFORE THE VEHICLE STOPPED. THE ANTI-LOCK BRAKE SYSTEM AND THE BRAKE INDICATORS ILLUMINATED. THE CONTACT STATED THAT THE FAILURE OCCURRED FIVE OTHER TIMES INTERMITTENTLY. ONCE THE VEHICLE WAS TURNED OFF AND RESTARTED, THE FAILURE WOULD STOP. THE VEHICLE WAS TAKEN TO THE DEALER (ED WHITTMEIER FORD IN CHICO, CALIFORNIA) FOR DIAGNOSTIC TESTING, BUT THE FAILURE COULD NOT BE DUPLICATED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 84,000. *TT CONSUMER STATED BRAKES FAIL INTERMITTENTLY WHEN THEY FAIL…

PASSENGER SIDE REAR INNER FENDER WELL RUSTED COMPLETELY THROUGH ABOVE THE REAR SHOCK CAUSING THE SHOCK TO POTENTIALLY BREAK THROUGH AND DROP THE WHOLE SUSPENSION AND CAUSE AND ACCIDENT OR FLIP OVER IF IT BROKE THROUGH DURING A TURN. THE REST OF THE VEHICLE HARDLY HAS ANY RUST ON IT. THE MARINER SHARES THE SAME INNER SHEET METAL AS THE FORD ESCAPE AND THERE HAVE BEEN MANY COMPLAINTS OF THIS HAPPENING TO ESCAPES. MY VEHICLE WAS STUDIED AT A FORD INVESTIGATION ABOUT 4 YEARS AGO FOR THIS PROBLEM. I WAS TOLD THEY WERE WORKING ON A SOLUTION AND NOTHING EVER HAPPENED. THE EMPLOYEE TOLD ME THAT THE UNDERCOATING THEY USED OF THESE YEARS OF ESCAPE/MARINERS WAS FAULTY AND BROKE DOWN PREMATURELY…
- Service brakes
THE BRAKE SYSTEM'S HYDRAULIC CONTROL UNIT ("HCU"). ON SEVERAL OCCASIONS WHILE DRIVING, THE BRAKE PEDAL WILL TRAVEL TO THE FLOOR WHILE TRYING TO BRAKE RESULTING IN NO BRAKING ACTION (IE., VEHICLE NOT SLOWING). THIS MIGHT HAPPEN FOR ONE OR TWO PEDAL DEPRESSIONS BEFORE THERE IS ANY SLOWING OF THE VEHICLE. THIS PROBLEM HAS PLACED ME IN SITUATIONS WHERE I HAVE TO TAKE EVASIVE ACTION TO NOT HIT A VEHICLE IN FRONT OF ME, OR TRAVELING INTO A CONTROLLED (WITH STOP SIGNS) INTERSECTION. BELOW THERE IS A SPACE TO SPECIFY 'WHEN DID THIS HAPPEN.' I AM INPUTTING THE MOST RECENT DATE OF THIS PROBLEM, BUT IT HAS HAPPENED AT LEAST TEN TIMES BEFORE THIS.
- Electrical system
TL* THE CONTACT OWNS A 2007 MERCURY MARINER HYBRID. THE CONTACT STATED THAT THE ALARM SYSTEM SOUNDED INDEPENDENTLY. THE VEHICLE WAS NOT DIAGNOSED AND THE FAILURE RECURRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 70,000.
- Engine
TL* THE CONTACT OWNS A 2007 MERCURY MARINER HYBRID. WHILE DRIVING APPROXIMATELY 60 MPH, THE ENGINE STALLED AND THE INSTRUMENT PANEL DISPLAYED A TRIANGLE WITH AN EXCLAMATION POINT. THE PANEL DISPLAYED THAT THE DRIVER NEEDED TO PULL OVER IMMEDIATELY. THE CONTACT PULLED OVER AND THE IGNITION HAD TO BE TURNED TO THE OFF POSITION FOR A FEW MINUTES IN ORDER FOR THE VEHICLE TO RESTART. THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS DIAGNOSED THAT THE MOTOR ELECTRONIC COOLANT PUMP FAILED AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND STATED THAT THE VEHICLE WAS NO LONGER INCLUDED IN NHTSA CAMPAIGN NUMBER: 14V526000 (ELECTRICAL SYSTEM).…

THE CONTACT MENTIONED THAT WHEN THE BRAKE PEDAL WAS DEPRESSED, THE VEHICLE JERKED FORWARD AND THE TRACTION CONTROL WARNING LIGHT ILLUMINATED.

- Steering
THE POWER STEERING WENT OUT IN MY MOTHER'S 2007 MARINER HYBRID WITH 72,000 MILES DUE TO FAILURE OF THE POWER STEERING CONTROL MODULE. AFTER SEARCHING ONLINE FORUMS, I FOUND THIS TO BE A RATHER COMMON ISSUE ON THE 05-07 MARINER AND ESCAPE HYBRIDS. THE REPAIR WILL COST JUST UNDER A THOUSAND DOLLARS ONCE YOU LOCATE THE PART. AFTER HAVING IT DIAGNOSED AT MY FORD DEALER, I CONTACTED FORD CUSTOMER CARE TO SEE IF THEY COULD RESOLVE THE ISSUE, AND THEY ACTED LIKE IT WAS SOMETHING THEY WERE UNAWARE OF EVEN THOUGH IT DOES NOT TAKE MUCH SEARCHING TO SEE IT'S A COMMON PROBLEM. ALSO IT'S A SAFETY ISSUE. THE SAME PART WAS RECALLED ON THE 08-11 ESCAPE AND MARINER HYBRIDS, AND THE RECALL SHOULD HAVE…
