About a month ago I contacted Beechmont Ford (600 Ohio Pike Cincinnati, Ohio 45245) in reference to Manufacturer Recall Number # 13S08 NHTSA Recall Number # 13V385000. I've wrote them three time and they have not responded. A week ago I chatted with Fords Hotline and they said they would do what they could. I've heard nothing back. Where do I go from here?
An SUV crashed into an apple store in Hingham Mass. The driver told police his foot became stuck to the gas pedal. More likely his foot became hooked under the brake pedal as he tried to quickly shift his foot from the gas pedal up and to the left onto the brake pedal. This has happened to me several times after accelerating and then having to make a 'panic' stop. I had to quickly wiggle-foot from under to the top of the brake pedal. Brake pedals should be changed from a T shaped to a 7 shaped configuration. This would eliminate the hook. T configuration-the 'stem' is attached under the center of the brake pedal 7 configuration-the 'stem' is attached under the right edge of the brake pedal
Driver side door jambed locked. Cannot exit the vehicle without sliding across to passenger door.

I AM WRITING TO YOU CONCERNING A LETTER I RECENTLY RECEIVED FROM THE FORD MOTOR COMPANY CONCERNING SAFETY RECALL NUMBER 13S08 / NHTSA RECALL 13V385 STEERING COLUMN SHAFT FOR MY 2009 GRAND MARQUIS, VEHICLE ID#XXXXX.. I RECEIVED THE FIRST NOTICE OF THIS RECALL OCTOBER 2013. I CALLED RICH FORD LOCATED AT 8601 LOMAS BLVD NE, ALBUQUERQUE, NM 87112, PHONE NUMBER (505) 292-0000 ON NOVEMBER 1, 2013 TO MAKE AN APPOINTMENT ON NOVEMBER 5, 2013, TO HAVE THE WORK DONE. ON NOVEMBER 4TH, I RECEIVED A CALL ASKING IF I DROVE THE CAR IN MICHIGAN. TOLD HER I BOUGHT THE CAR USED AND DID NOT KNOW ITS HISTORY. I WAS ADVISED BY RICH FORD THAT THE RECALL DID NOT APPLY TO MY CAR BECAUSE WE DID NOT LIVE IN A HIGH CORROSION AREA. AFTER RECEIVING THIS PHONE CALL, I CONTACTED FORD MOTOR COMPANY BY EMAIL ON NOVEMBER 4TH CONCERNING MY CONVERSATION WITH RICH FORD. I RECEIVED A REPLY TO MY EMAIL FROM TEENA A REPRESENTATIVE OF THE FORD CUSTOMER RELATIONSHIP CENTER (CRC) WHO INSTRUCTED ME TO CONTACT SERVICE ADVISOR ALISON AT RICH FORD TO ARRANGE FOR MY VEHICLE TO BE INSPECTED. I CONTACTED RICH FORD AND TOOK MY VEHICLE IN FOR THE REPAIRS. I WAS TOLD IT WOULD BE 2 TO 3 DAYS TO HAVE THE WORK DONE. ABOUT 4 HOURS LATER I RECEIVED A CALL FROM RICH FORD INFORMING ME THAT THE WORK HAD BEEN PERFORMED. A YEAR LATER, I RECEIVED ANOTHER LETTER FROM FORD MOTOR COMPANY INFORMING ME THAT I NEEDED TO GET THE RECALL WORK PERFORMED. I WENT INTO RICH FORD TO DISCUSS THIS, AND THEY TOLD ME THAT THE WORK HAD BEEN PERFORMED. LAST MONTH I AGAIN RECEIVED A LETTER FROM THE FORD MOTOR COMPANY SAYING THAT I NEEDED TO HAVE THE SAFETY RECALL WORK PERFORMED. I WENT TO THE NATIONAL HIGHWAY TRANSPORTATION SAFETY ADMINISTRATION AND PERFORMED A SEARCH ON MY VEHICLES VIN AND THE RESULT WAS A RECALL STILL BEING OPEN FOR THIS REPAIR. IS FORD MOTOR COMPANY RESPONSIBLE FOR HAVING THIS RECALL COMPETED OR NOT?

I NEED YOUR ASSISTANCE ON THIS MATTER. PLEASE. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR
TL* THE CONTACT OWNS A 2009 MERCURY GRAND MARQUIS. THE CONTACT RECEIVED NHTSA CAMPAIGN ID NUMBER 13V385000 (STEERING) HOWEVER, THE CONTACT WAS UNABLE TO HAVE THE VEHICLE SERVICED UNDER THE RECALL DUE TO THE REQUIRED PART NOT BEING AVAILABLE FOR THE REPAIR. THE MANUFACTURER WAS NOT NOTIFIED OF THE PROBLEM. THE CONTACT DID NOT EXPERIENCE A FAILURE.
THE TIRES ON MY 2009, MERCURY MARQUIS, ARE DRY ROTTED. I HAVE ALSO NOTED THAT THERE ARE HOLES IN THE SIDEWALLS ON ALL OF THEM ALONG WITH A LARGE BULGE IN THE RIGHT PASSENGER, SIDE TIRE WALL WITH A TEAR AND LARGE HOLE WHERE THE BULGE IS. I HAVE BEEN TRYING TO LOOK UP ON THE WEB SITE TO SEE IF MY TIRES ARE IN THE RECALL LISTS WITH SOME DIFFICULTY. I SINCERLY HOPE YOU CAN HELP ME WITH THIS PROBLEM AS I AM AFRAID TO DRIVE NOW AND MY HUSBAND HAS SEVERE PARKINSONS DESEASE AND I AM AFRAID SOMETHING IS GOING TO HAPPEN TO HIM. THANK YOU! I WILL BE LOOKING FORWARD TO YOUR RESPONSE.
I HAD CHECKED THE TIRE PRESSURES PRIOR TO A ROAD TRIP AND FOUND THEM AT 38 PSI. I RESET THE PRESSURES TO THE SPEC OF 33 PSI. SHORTLY THE TIRE MONITOR CAME ON AND SIGNALED A LOW TIRE PRESSURE. I RECHECKED AND THEY WERE OK. DURING MY TRIP THE LIGHT WOULD KEEP COMING ON AND I TRIED TO RESET THE SYSTEM TO NO AVAIL. ON MY RETURN, THE POWER DOOR LOCKS KEPT MALFUNCTIONING. THE DOOR KEY PAD WOULD WORK SOMETIME FOR BOTH THE DOORS AND TRUNK. THE NEXT TIME THEY MIGHT NOT. THE DOOR SWITCHES ON BOTH PASSENGERS AND DRIVERS SIDE WOULD WORK SOMETIMES. WITH BOTH THE TIRE PRESSURE SYSTEM AND THE DOOR LOCKS ACTING UP AND CREATING A NUISANCE, I TOOK THE CAR TO THE FORD DEALERSHIP, TWO RIVER FORD IN MOUNT JULIET, TN.. THE FOUND A SHORTED WIRE IN THE HARNESS GOING TO THE DRIVERS SIDE MODULE THAT COORDINATES MOST OF THE SAFETY SYSTEMS ON THE CAR. THERE WAS NO FIRE IN MY CASE, HOWEVER, THERE COULD HAVE BEEN. I DID RECEIVE A BILL FOR $272.30. MY CONCERN IS THAT FORD APPARENTLY DOES NOT ACCEPT ANY RESPONSIBILITY FOR WHAT I CONSIDER A SAFETY ISSUE WHETHER IT WAS CAUSED BY POOR SYSTEM DESIGN ON THE HARNESS LAYOUT OR ELECTRICAL CURRENT EXCEEDING THE WIRING CAPABILITIES. WAS IT CAUSED BY EXCESSIVE MOVEMENT IN THE HARNESS OR WAS IT CURRENT GOING THROUGH THE WIRES AS I TRIED TO RESET THE PRESSURE MONITORING SYSTEM 20-30 TIMES. I AM MORE THEN INTERESTED IN KNOWING HOW MANY SIMILAR FAILURES FORD HAS HAD IN THE GRAND MARQUIS AND THE FORD CROWN VIC. *TR
I WAS DRIVING AT 45 MPH AND APPLIED THE BRAKE TO STOP. THE ENGINE REVVED TO 2,000 RPM. I WAS ABLE TO STOP WITH VERY HARD BRAKING USING BOTH FEET. THE ENGINE CONTINUE REVVING AT 2,000 RPM EVEN AFTER THE CAR HAD STOPPED. I PLACED THE TRANSMISSION IN NEUTRAL AND THE ENGINE REVVED EVEN FASTER. THE ENGINE DID NOT SLOW DOWN UNTIL I TURNED OFF THE IGNITION. AFTER LEAVING THE ENGINE OFF FOR AROUND TWO MINUTES, I RESTARTED THE ENGINE AND IT RESUMED RUNNING AT AROUND 500 RPM. MY 23 YEAR OLD SON WAS SEATED NEXT TO ME AND VERIFIED THAT NOTHING WAS TOUCHING THE ACCELERATOR WHILE THE ENGINE WAS REVVING AT 2,000 RPM AND THAT BOTH OF MY FEET WERE ON THE BRAKE. THE ENGINE HAS REVVED WHEN I APPLIED THE BRAKE AT LEAST SEVEN OTHER TIMES; HOWEVER, THE REVVING STOPPED AFTER ONE OR TWO SECONDS. I HAVE TAKEN THE CAR TO A FORD DEALER THREE TIMES FOR THIS PROBLEM; HOWEVER, THEY HAVE NOT BEEN ABLE TO FIND THE CAUSE OF THE PROBLEM. *TR
MY WIFE WAS DRIVING AROUND 25 MPH AND LESS THAN ONE MILE FROM OUR HOUSE. WHEN SHE APPLIED THE BRAKES TO STOP AT A STOP SIGN THE ENGINE REVVED UP. I WAS RIDING WITH HER AND OBSERVED THE ENGINE REV TO AROUND 2,500 RPM BEFORE SLOWING DOWN. I ALSO OBSERVED THAT HER RIGHT FOOT WAS ON THE BRAKE AND THAT NOTHING WAS TOUCHING THE ACCELERATOR. THE CRUISE CONTROL HAD NOT BEEN TURNED ON. THIS WAS AT LEAST THE FOURTH TIME THIS YEAR THAT THE ENGINE REVVED UP WHEN THE BRAKES WERE APPLIED. THE DEALER COULD NOT FIND THE PROBLEM AND THE ENGINE DID NOT REV WHILE THE DEALER WAS TESTING THE CAR. *TR
TL* THE CONTACT OWNS A 2009 MERCURY GRAND MARQUIS. THE CONTACT STATED THAT WHILE THE BRAKES WAS ENGAGED THERE WAS AN SUDDEN INCREASE ON ENGINE RPMS. THE CONTACT MENTIONED THAT THE REAR WHEELS STARTED TO SPIN AND IN ORDER TO STOP IT HE HAD TO SHIFT INTO NEUTRAL. THE VEHICLE WAS TAKEN TO THE DEALER WHO WAS UNABLE TO DUPLICATE THE FAILURE. THE FAILURE MILEAGE AND CURRENT MILEAGE WAS 33,000.
I APPLIED THE BRAKES AT AROUND 20 MILES PER HOUR ON JANUARY 25 AND THE MOTOR ACCELERATED FOR ONE OR TWO SECONDS. I WAS ABLE TO STOP THE CAR BY PRESSING THE BRAKES MUCH HARDER THAN NORMAL. ON JANUARY 26 I APPLIED THE BRAKES AT AROUND 60 MILES PER HOUR AND THE MOTOR AGAIN ACCELERATED FOR ONE OR TWO SECONDS. I CONTINUED TO PRESS THE BRAKES, THE MOTOR SLOWED DOWN AND THE CAR EVENTUALLY SLOWED. IT SOUNDED LIKE PRESSING THE ACCELERATOR DOWN HARD TO PASS ANOTHER CAR ON A TWO LANE ROAD. *TR
THE LEFT TURN SIGNALS (FRONT, REAR & DASH) BLINK FASTER THAN THE RIGHT ONES INDICATING A BURNT OUT BULB EVEN THOUGH THE LEFT BULBS WORK. WE REPLACED THE FRONT & REAR BULBS TWICE AND THEY WORKED NORMAL FOR A SHORT PERIOD OF TIME. THEN THEY REVERT TO BLINKING FAST. I REPLACED THE BULBS THE FIRST TIME AND THE DEALERSHIP SERVICE CENTER REPLACED THE BULBS THE SECOND TIME. THERE MUST BE SOMETHING WRONG IN THE ELECTRICAL SYSTEM. I'VE NOTICED THIS WITH OTHER GRAND MARQUIS ALSO. *TR

The basics
How to read this data
Complaints, recalls, investigations — here’s what each number actually tells you about a used Mercury Grand Marquis, 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 Grand Marquis has 1,723 complaints on record across 10 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 Grand Marquis has 26 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. 120 of the Mercury Grand Marquis's 1,723 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 Grand Marquis vehicles on the road — not any specific car. Two Mercury Grand Marquis 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 Grand Marquis has 0 investigations on record (0 active). Investigations listed above may have already led to the recalls shown on this page.
