Owner complaints
NHTSA complaint reports
1,305 totalThese are consumer-submitted safety complaints filed directly with NHTSA. Each complaint describes a real owner's experience. Complaints flagged as crash-related or fire-related are highlighted.
90sWhile driving, the vehicle will suddenly display a warning message that says “Stop Safely Now”. When this message appears, the hybrid system overheats and the vehicle immediately loses power. The gasoline engine and electric motor both shut down without warning, even at highway speeds. I am forced to coast to the side of the road, which is extremely dangerous in traffic. This happens after the vehicle has been driven for a short period of time. The cooling fans appear to be running, but the hybrid electronics system overheats and triggers the shutdown safety mode. After waiting for the vehicle to cool down, it will restart, but the problem continues every time the car reaches normal driving temperature. This issue matches the symptoms covered under Ford’s previous safety actions and customer satisfaction programs for the 2005–2008 Ford Escape and Mercury Mariner Hybrid (hybrid electronics overheating and shutdown). The dealership states that no recall appears under my VIN, but the safety failure is identical. The vehicle becomes unsafe and inoperable with no advance warning beyond the brief “Stop Safely Now” message. This defect poses a serious risk of a crash, injury, or death due to the sudden loss of propulsion in traffic.

TL* THE CONTACT OWNS A 2007 MERCURY MARINER. WHILE THE CONTACT'S SON WAS DRIVING THE VEHICLE, THE TRANSMISSION SLIPPED AND WENT INTO OTHER GEARS. WHEN THE VEHICLE WAS IN NEUTRAL, IT SHIFTED INTO DRIVE ON ITS OWN. ON ANOTHER OCCASION, THE CONTACT'S SON STATED THAT THE VEHICLE FELT AS IF IT WERE DRAGGING AFTER IT JUMPED. IN ADDITION, "OVERDRIVE" APPEARED ON THE CONTROL PANEL THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC, BUT WAS NOT DIAGNOSED OR REPAIRED. THE VEHICLE WAS THEN TOWED TO ANOTHER INDEPENDENT MECHANIC WHO WAS UNABLE TO DUPLICATE THE FAILURE. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND INFORMED THE CONTACT TO CALL NHTSA. THE DEALER WAS NOT CONTACTED. THE FAILURE MILEAGE WAS 152,000.

I HAVE JUST FOUND OUT I HAVE LOST 2ND GEAR AND 4TH GEAR IS ON ITS WAY OUT ON MY CAR. APPARENTLY THIS IS A PROBLEM THAT FORD HAS KNOWN ABOUT AT LEAST SINCE 2012, ACCORDING TO AN ONLINE FORD MOTOR COMPANY PUBLICATION, MAYBE EVEN EARLIER. THE PUBLICATION STATES THAT IT AFFECTS 2007-2008 FORD ESCAPES AND MERCURY MARINERS. WHAT I WANT TO KNOW IS, IF THEY KNEW ABOUT IT AT LEAST FIVE YEARS AGO, WHY WASN'T THERE A RECALL AND IF NOT A RECALL, SOME KIND OF FINANCIAL ASSISTANCE/COMPENSATION FOR THE REPAIRS? I'VE SHOPPED AROUND FOR PRICES AND THE BEST I COULD FIND WAS $2200.00 FOR THE REPAIR PLUS ANOTHER $225.00 FOR A RENTAL TO USE WHILE MY CAR IS BEING REPAIRED. THE REPAIR IS GOING TO TAKE 3-5 DAYS.
MY SON WAS USING OUR CAR HE DROVE IT TO WORK... ALL WAS FINE...HE USED THE CAR TO GO GET LUNCH IN THE SHOPPING CENTER... DROVE BACK FROM THE SHOPPING CENTER TO A PARKING SPOT OUTSIDE HIS JOB LOCATION... HE THEN COMPLETED HIS SHIFT AT DICK'S SPORTING GOODS WHERE MY WIFE AND I MET UP WITH HIM...WE ALL PROCEEDED TO OUR CAR AND TRUCK WHICH WERE PARKED ACROSS FROM ONE ANOTHER...MY WIFE AND SON GOT IN THE MERCURY I GOT IN MY TRUCK...

TL* THE CONTACT OWNS A 2007 MERCURY MARINER. AFTER DRIVING AND PARKING THE VEHICLE, THE CONTACT COULD NOT REMOVE THE KEY FROM THE IGNITION. THE CONTACT HAD TO TURN THE STEERING WHEEL AND MANEUVER THE KEY IN ORDER TO GET IT TO RELEASE. THE CONTACT STATED THAT THE FAILURE RECURRED SEVERAL TIMES AND WAS GRADUALLY GETTING WORSE. THE VEHICLE WAS NOT TAKEN TO A DEALER. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 10,500.
TL* THE CONTACT OWNS A 2007 MERCURY MARINER. THE CONTACT STATED THAT THE FRONT AND REAR DRIVER SIDE SEAT BELTS FAILED TO LATCH. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 100,000.
THE VEHICLE HAD BEEN DRIVING PERFECTLY NORMAL ALL DAY. IN THE EVENING, WHILE DRIVING IN A HEAVILY-TRAFFICKED AREA, UNEXPECTEDLY OUR MARINER WOULD NOT SHIFT OUT OF 1ST GEAR - THE ENGINE REVVED, BUT THE CAR WOULD JUST BARELY MOVE. IT FINALLY SHIFTED INTO 3RD GEAR, BUT NEVER WOULD GO INTO 4TH. ALL THE WHILE, THE O/D LIGHT ON THE INSTRUMENT PANEL WAS GOING ON AND OFF. THIS PATTERN CONTINUED FOR SEVERAL DAYS WHILE WE HAD OUR MARINER INSPECTED AT NUMEROUS REPAIR SHOPS; THE END RESULT WAS THAT WE HAD TO HAVE THE TRANSMISSION REBUILT AT A COST OF $1700. AT ONLY 111,000 MILES! ALL OF THE TRANSMISSION REPAIR SHOPS THAT WE TALKED WITH STATED THAT THIS IS A COMMON OCCURRENCE IN THIS YEAR-MODEL FORD PRODUCT, MANY TIMES WAS FAR LESS MILEAGE THAN OURS HAD. *TR
MY 18 YEAR OLD SON WAS DRIVING MY 2007 MERCURY MARINER, WHEN IT STARTED MAKING LOUD NOISES AND SHAKING LIKE CRAZY, HE WAS BARELY ABLE TO KEEP THE VEHICLE RUNNING TO GET HOME. WHEN MY HUSBAND LOOKED AT VEHICLE AND SAW WHAT IT WAS DOING, HE THINKS THE TRANSMISSION HAS GONE OUT ON IT. WE HAD DRIVEN THE VEHICLE TO CHURCH SUNDAY MORNING (SAME DAY) AND THERE WAS NO SIGNS OR SYMPTOMS OF ANY KIND OF PROBLEM. I PURCHASED THE VEHICLE USED, AND IT HAS NOT HAD A PROBLEM EXCEPT FOR THE SHIFTER HAD TO BE REPLACED ABOUT 3 MONTHS AGO...MECHANIC STATED THAT THERE HAD BEEN SOMETHING SWEET SPILLED INSIDE OF THE SHIFTER, HOWEVER, I DRIVE THE VEHICLE 99.9% OF THE TIME AND I DRINK WATER...... AFTER RESEARCHING AND READING ALL THE COMPLAINTS ON THIS VEHICLE ON THIS WEBSITE, I DO REALIZE THAT THERE IS A MANUFACTURED DEFECT IN THE TRANSMISSION AND THE SHIFTER. HOW AND WHY HAS THERE NOT BEEN A RECALL ON THESE VEHICLES? WHY DIDN'T SOME OF THE WARNING LIGHTS COME ON? WE ARE VERY FORTUNATE THAT THIS HAS NOT HAPPENED BEFORE NOW AND CAUSED US TO HAVE AN ACCIDENT. *JS
THE CAR JUST LOST POWER WHILE DRIVING. SURGED A BIT THEN WAS OPERATING AT REDUCED POWER LIKE IT WAS LIMPING EVENTUALLY IT JUST STALLED AND THE GAS WOULD JUST REV THE ENGINE. FORD FIXED THE CAR UNDER WARRANTY. IF THIS HAS HAPPENED AT HIGHWAY SPEEDS IN TRAFFIC IT WOULD HAVE CAUSED A SEVERE ACCIDENT AS CARS WOULD HAVE BEEN DODGING A STALLED CAR AT HIGHWAY SPEEDS-. *TR
CAR LOST POWER WHILE DRIVING-- IT OPERATED AT A LIMP AT FIRST-- JUST PRIOR TO THAT WENT FORWARD QUICK, THEN IT JUST STALLED WHILE DRIVING WHILE IN GEAR. THE GAS JUST MADE THE ENGINE REV. THE CAR THE NEXT DAY AFTER GETTING TOWED OPERATED AND THE SAME THING HAPPENED WHILE THE SERVICE STATION TOOK THE CAR FOR A TEST DRIVE. THEY HAD TO TOW IT BACK. THIS SAME PROBLEM WAS FIXED UNDER WARRANTY (20,000 ON APPROX. 03/2008). IT HAPPENED AGAIN. FORD REFUSED TO AGREE THAT THERE IS SOMETHING WRONG WITH THE DESIGN ETC. IF THIS HAD HAPPENED ON THE HIGHWAY AT HIGHWAY SPEEDS THE RESULTS COULD HAVE BEEN TRAGIC. I THINK IT HAS SOMETHING TO DO WITH THE THROTTLE PROBLEM... THE CAR LIMPS JUST AS EVERYONE AS COMPLAINED ABOUT. I HAVE NO IDEA WHAT WAS ACTUALLY FIXED UNDER WARRANTY AS THE PARTS MEAN NOTHING. PISTONS, GASKETS, SENSOR TURBI, HUB PLATE ASY, SEALS, AND MANY OTHER PARTS. *TR
COMING OFF A STOP SIGN, THE VEHICLE WOULD NOT SHIFT INTO SECOND, COULD FEEL IT FINALLY JUMP INTO 3. TOOK IT TO A TRANSMISSION SHOP AND WAS TOLD THE TRANSMISSION HAD NO 2 AND 4TH GEARS. UPON LOOKING ONLINE, TRANSMISSIONS AND POWERTRAINS ARE KNOWN DEFECTS WITH THIS MODEL/YEAR. JUST HAD TO SPEND $2000.00 TO HAVE THIS REPAIRED AS FORD IGNORED PREVIOUS COMPLAINTS FROM CONSUMERS!! *TR

The basics
How to read this data
Complaints, recalls, investigations — here’s what each number actually tells you about a used Mercury Mariner, in plain English.
What is an NHTSA Complaint?
An NHTSA safety complaint is a report filed directly by a vehicle owner or driver describing a safety-related issue. Anyone can submit a complaint at NHTSA.gov. The number of complaints is a signal of how common a problem is — but complaints per model-year matter more than raw totals, since popular vehicles naturally receive more reports. The Mercury Mariner has 1,305 complaints on record across 7 model years.
What is a Safety Recall?
A safety recall is a mandatory campaign issued by NHTSA when a vehicle component poses an unreasonable risk to safety or does not comply with federal motor vehicle safety standards. Unlike complaints (which are owner-reported), recalls are formally investigated and confirmed by regulators. Manufacturers must fix recalled vehicles free of charge. The Mercury Mariner has 22 recall campaigns in the NHTSA database.
What Are Crash Complaints?
Crash complaints are NHTSA filings where the owner indicates a crash occurred as part of the incident. 36 of the Mercury Mariner's 1,305 complaints involved a crash. This metric is particularly important because it indicates how often defects resulted in actual collisions — a key safety signal beyond general reliability.
How Is the Reliability Verdict Calculated?
The reliability verdict (Poor) is generated by analyzing the vehicle's total complaints, recall history, crash complaint ratio, fire complaint ratio, and top component failures relative to class averages. This verdict gives buyers a quick interpretation before they review year-level details and VIN-level history. It should be treated as one decision input, not a substitute for a VIN-specific report.
Why Do Newer Years Have Fewer Complaints?
Newer model years appear to have fewer complaints because there has been less time for owners to file them. Complaints accumulate over years of ownership. A 2020 model year vehicle will typically show fewer complaints than a 2015 model year even if it is less reliable — simply because fewer owners have had time to report issues. Focus on complaints per year of market presence when comparing across model years.
Fleet Data vs. Individual VIN
Everything on this page reflects aggregated data across all Mercury Mariner vehicles on the road — not any specific car. Two Mercury Mariner vehicles of the same year can have very different histories: one may have been in three accidents and have an open recall; another may be clean. A VIN check gives you the individual car's history: accidents, title brands, odometer records, service history, and real-time recall status.
What Are NHTSA Investigations?
When NHTSA receives a pattern of related safety complaints, it opens a formal investigation. A Preliminary Evaluation (PE) is the first stage — NHTSA determines if a safety defect may exist. If evidence is strong, it escalates to an Engineering Analysis (EA), which can result in a mandatory recall. The Mercury Mariner has 0 investigations on record (0 active). Investigations listed above may have already led to the recalls shown on this page.
