Tiles: each year’s median failure mileage. Latest: the 1995; earliest: the 1997, and the 1995 is 2 years older (part of the gap is age). 3 of these years carry fewer than 30 reports with an odometer reading and show no median at all, rather than one computed from a handful.

Known problems with the 1992–1997 Grand Marquis
Intake Manifold (composite) 1996–1997
The plastic/composite intake manifold on the 4.6L 2-valve V8 develops fatigue cracks at the coolant crossover duct (splits across the front, behind the alternator), dumping coolant and risking overheating. Ford's formal recall (01M02) covered only police/fleet Crown Victorias; a December 2005 class-action settlement covered consumer 1996-2001 Grand Marquis, Town Car and Crown Victoria owners with reimbursement of about $735. Manifolds with an aluminum crossover superseded the all-plastic part from roughly 2002.
Rear Air Suspension 1992–1997
On air-suspension-equipped cars, rear air springs and the compressor leak and fail, leaving the car sagging at the rear; a common conversion-to-coil repair.
