Owners have filed 449 complaints
about the 2003 Mercury Grand Marquis with NHTSA between 2002 and 2026.
The largest single group is the lights.
Across this model's run it ranks 1 of 19 worst.
The letter says how bad. This says what kind — whether this year drew
an unusual number of complaints, unusually dangerous
ones, or failures that arrived unusually early.
The dashed ring is 50 — the national norm. Further out is worse.
Complaint volume — 100
Against the median year of the Mercury Grand Marquis. 50 means typical for this
model; 100 means roughly double.
Severity — 55
10.7% of these complaints
involved a crash, fire, injury or death, against a national rate of
9.7%.
Early failure — 25
15% of failures with a mileage on record happened under
36,000 miles, against a national rate of
29%.
How 2003 compares with every other Mercury Grand Marquis
NHTSA files every complaint against a named sub-assembly, not just a
system. This is the difference between knowing it was "the engine" and
knowing which part of it — the list to hand a mechanic.

When owners complained
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

NHTSA investigations into the 2003 Mercury Grand Marquis
An investigation is the step before a recall: the agency has seen enough
complaints to look into a pattern itself. An open one means it thinks
something may be wrong and nothing has been fixed yet.

Recalls on the 2003 Mercury Grand Marquis
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.
United States — NHTSA

EXTERIOR LIGHTING:HEADLIGHTS
Ford Motor Company (Ford) is recalling certain model year 2003-2005 Ford Crown Victoria and Mercury Grand Marquis vehicles manufactured October 3, 2001, to August 2, 2005. The affected vehicles have a lighting control module (LCM) that may fail, resulting in a loss of headlights.
Risk: A loss of headlights can reduce driver visibility and increase the risk of a crash.

Electrical
On certain vehicles, a defect in the Lighting Control Module could cause the headlight high and low beams to become inoperative without warning, causing the headlights to revert to reduced-voltage daytime running light function. This would cause a reduction in lighting output, potentially increasing the risk of a crash causing injury and/or damage to property. Correction: Dealers will replace the Lighting Control Module.

I started Mercury with foot on break like normal. Shifted into reverse. Car accelerated backwards at full speed. Brakes did not stop car. Attempted to shift into neutral but went into drive instead. Car accelerated forward at full speed with my foot still on break. Car hit metal post and tree knocking them down and dragging the tree 50 to 60 feet before stopping with my foot still on the break. Car had stopped accelerating. I turned off the ignition. This unintended acceleration had happened before. Two different dealers attempted to fix the problem. Both of them thought they had been successful but it happened again. Previously, applying the brakes stopped the car, but not this time. Someone could have been injured severely or killed.

The Lighting Control Module has failed and my brake lights and dash board lights turn off after couple minutes while driving with the lights on. I took my vehicle in to dealer already once for problem to be fixed a year ago. They did repair but now same problem is occurring again. 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. This affects my life. I've called other dealers and they refuse to do the work.
