Exactly what failed

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 2004 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 2004 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

15V861000

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.

CERTAIN AFTERMARKET FUEL FILTERS SOLD UNDER THE PUROLATOR BRAND NAME, P/N F65277, SHIPPED FROM JANUARY 16 THROUGH JUNE 2, 2006, FOR USE ON THE ABOVE LISTED PASSENGER VEHICLES. DUE TO INCORRECT DESIGN, THE QUICK CONNECTORS MAY NOT FULLY SEAT WITH THE TUBE INTERFACE, EVEN THOUGH THE PERSON MAKING THE CONNECTION MAY BELIEVE THAT THE QUICK CONNECTOR IS FULLY ATTACHED.

Risk: FAILURE OF THIS CONNECTION COULD LEAD TO FUEL SPILLAGE AND, IN THE PRESENCE OF AN IGNITION SOURCE, A FIRE COULD OCCUR.

Canada runs its own recall programme, and its campaigns do not always mirror the American ones.

Recall 2015610 14,714 units in Canada

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.

VEHICLE SPEED CONTROL

While driving, I came to a stop light and suddenly, the car idled high and lurched forward while my foot was on the brake, luckily, I was stopped well away from the vehicle in front of me. The car idled high and seemed to have a mind of it's own. I took the back roads home and backed into our garage. The car smelled hot, and I though I had smoked my brakes, trying to keep control of it. Later that night, I told my husband about the car's actions and he did not believe me, though my daughter who was with me at the time confirmed that the car had indeed accelerated on it's own. My husband started the car and it did idle high and get hot once again, although only parked with no one in it. He thought he knew what the problem was and we turned off the car and closed the hood and went inside to order the part. A few minutes later, we heard a couple popping noises and I opened the door that led into the garage from the basement. Smoke was coming into the house and my husband said that a flame shot over my head. The car had caught on fire under the closed hood. We called the fire department, but by the time they arrived, a good portion of the basement was on fire. The house was a total loss. My husband though that the pvc elbow under the hood was sticking closed, so that is the part we were going to order. Unsure, if that was the real cause or not. The car did not have any warning lights or any other indications of a problem before this incident.
