1991 Ford Grand marquis problems
The Mercury Grand Marquis is an automobile that was produced by Mercury from the 1975 until 2011 model years. Introduced as the flagship sub-model of the Mercury Marquis in 1975, the Grand Marquis became a stand-alone model line in 1983, serving as the largest Mercury sedan. The model line served as the sedan counterpart of the Mercury Colony Park station wagon up to 1991. The fourth generation was the basis of the 2003 and 2004 Mercury Marauder.
From 1979 until 2011, the Grand Marquis shared the rear-wheel drive (RWD) Panther platform with the Ford LTD Crown Victoria (Ford Crown Victoria after 1992), and from 1980, the Lincoln Town Car. For over three decades, the Ford and Mercury sedans were functionally identical, with two of the three generations of the model line sharing the same roofline. The Grand Marquis was available as a four-door sedan for nearly its entire run; from 1988 to its final year in 2011, it was the only body style that was offered. A four-door hardtop was available from 1975 to 1978 and a two-door hardtop coupe from 1975 to 1987.
The Grand Marquis was the second-best-selling Mercury line (after the Cougar) with 2.7 million units produced; at 36 years of continuous production, the Grand Marquis was the longest-running Mercury nameplate (the Cougar, 34 years). Ford manufactured the Grand Marquis, alongside the Mercury Marquis, Mercury Marauder, Ford (LTD) Crown Victoria, and (beginning in 2007) the Lincoln Town Car, at two facilities: the St. Louis Assembly Plant in Hazelwood, Missouri (1979-1985) and the St. Thomas Assembly Plant in Southwold, Ontario, Canada (1986-2011).
Ford announced the discontinuation of the Mercury brand in 2010, but a few 2011 model-year Mercurys were made. The last Grand Marquis - and the final Mercury branded car - was produced on January 4, 2011, at St. Thomas Assembly.

Common 1991 Ford Grand marquis problems
The Ford Grand Marquis, produced from 1975 to 2011, is known for its reliability and decent quality-to-price ratio. However, there are some common issues that owners have reported, particularly in the steering, visibility, intake manifold, and transmission systems.
- Visibility Issues: Another common problem reported by Grand Marquis owners is visibility issues, specifically related to the windshield. Premature cracks in the windshield were a common occurrence, and the manufacturer admitted that a production mistake led to improper windshield retention. This issue was addressed with a recall in 2006, but drivers should still be aware of potential problems with windshield wiper modules that may not operate correctly under heavy load.
- Intake Manifold Cracks: The second and third-generation models of the Grand Marquis often had issues with coolant leaks caused by cracked intake manifolds. This problem was due to the use of a completely plastic manifold that was prone to cracks. Coolant leaks can lead to engine overheating, which can cause significant damage to the engine. The manufacturer updated the manifold with a metal coolant pipe, which resolved the issue.
- Transmission Problems: Many Grand Marquis owners have reported transmission problems, specifically transmission failure caused by front pump failure. This issue can lead to expensive repairs, with the cost of a new transmission ranging from $1,400 to $2,000, not including labor rates.
These are some of the most common problems reported by Ford Grand Marquis owners. While the car is known for its reliability, it is important to be aware of these potential issues and to address them promptly to avoid more significant repair costs down the line.
