I went back to dealer Sunrise Ford in Fontana and they said recall work is only warranty for 1 year or 12k miles. The work was done in December 2023. They want to charge me $230.00 for diagnostic. But issue is same problem as before. Recall number is 15S39. Driving without brake lights is dangerous and has limited my driving. I cannot go out at night. I do not have another vehicle.

I received a recall on my car in 2019 to change the lighting control module as my headlights could go out without warning. Although I had not experienced this, I brought my vehicle to the local Ford dealer who changed the part. Over the pandemic and now since my wife and I are in declining health we have driven very little after dark. However, I recently had to go to the pharmacy at Walmart and returned home after dark but my headlights went out completely. Now I am having this problem and the local Ford dealer said there was no second recall so he wants to charge me between $500 and $600 to correct the problem. I think this is Ford's responsibility to correct. Please assist in making the manufacturer aware of this.

I am the owner of a 2003 Mercury Grand Marquis. Several weeks ago the power steering on the vehicle quit. This was not the result of the power steering pump. The linkage in the steering system had ceased, causing the vehicle to be dangerously unsteerable. I have had this repaired at a cost of $575 dollars. I believe this is a safety issue that need immediate investigation and a safety recall. I contacted Ford Motor Company and was sent to Chat contact Shakura who gave me the Corporate runaround. We were lucky as this happened on a side road at low speed. If it had happened on an Interstate with speeds of 65 to 80 MPH I feel this could have resulted in a major accident. I should also point out this steering item is in Ford Crown Victorias and more than likely in Lincoln Continentals. Please advise and contact me with questions. Thank you in advance as this need to be resolved.

WHEN DRIVING THE CAR AND MAKING A TURN IN EITHER DIRECTION, AT THE POINT THE STEERING WHEEL HAS TURNED 180 DEGREES AND IS NOW UPSIDE DOWN FROM "NORMAL POSITION", IT FEELS AS THOUGH THE STEERING WHEEL IS GOING TO COME OFF!!! IT ROCKS BACK AND FORTH IN THE UPSIDE DOWN POSITION. ALSO.... AT TIMES IT FEELS HARD TO TURN THE WHEEL IN EITHER DIRECTION. THIS PROBLEM APPARENTLY COMES FROM THE UPPER AND LOWER STEERING SHAFTS WHERE THE U-JOINT CONNECTS THE TWO STEERING SHAFTS. IF I SLATHER GREASE ON THE SHAFTS AND WORK THE STEERING WHEEL BACK AND FORTH ABOUT 30 TIMES, THE "TOUGH STEERING" OR THE FEELING OF NO POWER STEERING SUBSIDES, BUT COMES BACK IN ANYWHERE FROM 1 WEEK TO A MONTH! I CAN BE DRIVING ON THE INTERSTATE AND ALL AT ONCE I CAN NOT CHANGE LANES, WHICH IS VERY SCARY AT TIMES!!! WHEN THIS HAPPENS AT 65 MPH IT IS ALMOST TIMPOSSIBLE TO STEER THE CAR!!! IT IS ALSO VERY DANGEROUS MAKING A TURN AT 10-20 MPH AS ON NUMEROUS OCCASIONS, THE POWER STEERING QUITS WORKING AND I ALMOST RAM THE CAR SITTING AT THE STOP LIGHT BECAUSE THE CAR WON'T MAKE THE COMPLETE TURN!!! MANY TIMES, I HAVE HAD TO STOP DEAD TO KEEP FROM HITTING THE CAR AS I AM TRYING TO TURN RIGHT, AND THEN WITH ALL MY STRENGTH, CRANK AND MUSCLE THE STEERING WHEEL TO COMPLETE MY RIGHT TURN! ( AND I AM A 6', 245 LB. MAN IN PRETTY GOOD SHAPE!!!) I HAD HEARD FROM OTHER GRAND MARQUIS OWNERS THAT THERE WAS A RECALL ON EARLIER MODELS OF THE GRAND MARQUIS (2000-2002 MODELS) FOR THE SAME PROBLEM, BUT FOR SOME REASON, THE 2003 GRAND

WHILE DRIVING THE VEHICLE THE HEADLIGHTS WOULD GO OUT AND STOP WORKING. THE ONLY WAY I COULD DRIVE AT NIGHT WAS TO PULL THE SWITCH TOWARDS ME AND KEEP THE BRIGHTS ON WHILE DRIVING. IF I LET GO THE LIGHTS WOULDN'T STAY ON AND I COULDN'T SEE THE ROAD. I TRIED TO USE THE SWITCH ON THE DASH TO TURN ON THE HEADLIGHTS BUT IT WOULD ONLY WORK FOR THE PANEL LIGHTS ON THE DASH BOARD. THIS HAPPENED WHILE I WAS DRIVING AT NIGHT WITH MY FAMILY IN THE CAR IT WAS VERY SCARY AND WE WERE DRIVING ON TOADS WITH NO STREET LIGHTS LIGHTS. THIS OCCURRED ON WED, FEB. 20 2019. ONCE THIS HAPPENED I PULLED OVER PUT THE CAR IN PARK TURNED THE CAR OFF AND RESTARTED IT. I PUT THE CAR IN DRIVE AND TRIED TO TURN ON THE HEADLIGHTS BUT NOTHING WOULD COME ON SO I PULLED THE SWITCH TOWARDS ME AND KEEP IT LIKE THAT SO THE BRIGHT LIGHTS WOULD COME ON AND I COULD SEE THE ROAD TO DRIVE THIS FOR 30 MIN UNTIL WE GOT HOME.

COMING FROM A CONCERT WHICH THANKFULLY WAS VERY CLOSE TO HOME, THE HEADLIGHTS DID NOT TURN ON AND THERE WERE NO DASH LIGHTS. THE VEHICLE WAS NOT IN MOTION BUT AS THE CAR WAS STARTING TO MOVE, STILL NO LIGHTS. THERE WAS A RECALL ON THIS VEHICLE IN 2014(LCM #15S39) THAT WAS REPAIRED AND REIMBURSED BY OUR LOCAL FORD DEALERSHIP. THIS WAS A KNOWN ISSUE FOR 2003-2005 MERCURY GRAND MARQUIS AND 2003-2005 CROWN VICTORIA. I HAVE SINCE SEEN COMPLAINTS COME UP AS OF JAN.2018 THAT THIS PROBLEM HAS AGAIN COME TO LIGHT. THIS IS A HORRENDOUS SAFETY ISSUE AND NOT AN INEXPENSIVE FIX. HOW MANY MORE TIMES WILL THIS KEEP HAPPENING? WE LOVE THIS CAR, HAVE HAD IT FOR 13 YEARS AND IT HAS LESS THAN 90000 MILES ON IT. TRIED CONTACTING FORD CUSTOMER SERVICE AND THEY WERE NO HELP!! WE JUST WANTED TO MAKE THIS KNOWN THAT OBVIOUSLY THIS IS AN ONGOING PROBLEM WITH THIS PARTICULAR YEAR VEHICLE.

2003 Mercury Grand Marquis: questions buyers ask

Is the 2003 Mercury Grand Marquis a good car?

Going by the federal record, it is one of the Grand Marquis years to avoid: owners filed 362 complaints, 2.3 times as many as a typical Grand Marquis year. The most common complaint is about the headlights (50%).

What is the most common problem with the 2003 Mercury Grand Marquis?

The headlights: 180 of the 362 complaints (50%) are about it. Owners most often say it sets off warning lights on the dash (4%). The typical report comes at 93,000 miles.

How many recalls does the 2003 Mercury Grand Marquis have?

2 safety recalls on file with NHTSA, the most recent filed Dec 22, 2015. The largest, 15V861000, covered 296,004 vehicles. Recall repairs are free at a dealer; whether a specific car still has one open depends on its VIN.

At what mileage do 2003 Mercury Grand Marquis problems start?

Half of the complaints that record an odometer reading came in before 85,194 miles. For the headlights the midpoint is 93,000 miles.

Has NHTSA investigated the 2003 Mercury Grand Marquis?

Yes, 6 times. The latest, PE15028 ("Loss of headlights"), was opened Aug 10, 2015 and closed Jan 8, 2016.

Are there service bulletins for the 2003 Mercury Grand Marquis?

The manufacturer filed 90 technical service bulletins and other notices for it with NHTSA, most of them about the electrical system (19), the engine (16) and the headlights (6). They include a warranty extension, CSP-14-N-01, filed Apr 11, 2014. A bulletin is a repair instruction to dealers, not a recall: the fix is usually free only under warranty.

Reading this record

Complaint volume is well above typical for a single model year.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.

Most recent recall on file: Dec 22, 2015. Source: NHTSA Office of Defects Investigation.
