The 2002MERCURYGRAND MARQUIS carries 101 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 11 crashes, 2 fires, 8 injuries, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2002 GRAND MARQUIS is vehicle speed control with 16 filings, followed by steering (9) and electrical system (8). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 2 active recall campaigns, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.
NHTSA currently has 3 investigation files overlapping the 2002 GRAND MARQUIS. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

For sometime now the Headlights on my 2002 Mercury Grand Marquis appear to fade or dim soon after turning them on; giving the impression they are losing power and about to fail. I live in the mountains and am very familiar with each and every turn I See on the roads I travel. You See that Is The Matter of Fact- If My Headlights Failed; I Would Not See The Turn Possibly A Fatal Fact.
?yrs.ago While backing out of parking space at Calaveras Lumber, after shifting into reverse, & removing my foot from the brake; the engine appeared to receive a huge burst of fuel which shot me backward like a rocket slamming my vehicle into and wedging it under the frame of a pickup truck parked in the same lot. I am glad I was parked and had my foot on the brake prior to this unit or system malfunction otherwise the injuries could easily have been fatal on the highway. I think this defect may be a contributing factor to the car dying recently while on my way to a Wedding Reception in Roseville, which left me stranded after dark for 41/2hrs and 71/2hrs. 2days later. I have not been able to start vehicle since and mechanics unable to diagnose why the engine is fuel starved when system parts tested appear to be in good working order. Something seems to be shutting off power or preventing power to the fuel pump and it is not the inertia switch, relays, fuses etc.. Components have be

THE SEAT BELTS WILL NOT STAY ATTACHED. YOU CAN PUT THEM ON AND THEY APPEAR TO BE LOCKED IN AND YOU CAN PULL ON THEM TO SEE IF THEY ARE ATTACHED AND THEY APPEAR TO ATTACH BUT THEN WHILE JUST SITTING, THEY MAY POP-OFF YOU AND BECOME DISENGAGED LEAVING YOU WITHOUT YOUR SEAT BELT ON YOU. THIS CAN OCCUR IF THE CAR IS IN MOTION OR IF IT IS STANDING STILL. SOMETIMES IT WILL EVEN POP-OFF RIGHT AFTER YOU PUT IT IN THE BUCKLE. THEY ARE FAULTY. WE CALLED FORD AND THEY WILL NOT DO ANYTHING TO REPAIR OR RECALL IT. I TALKED TO 2 PEOPLE AT FORD CUSTOMER CARE AND SENT THEM AN EMAIL, ALSO BUT THEY WILL NOT DO ANYTHING TO HELP US. WE ALSO CONTACTED A MERCURY DEALER WHO TOLD US TO CALL FORD.
