What Problems Does the 1998 Mercury Grand Marquis Have?
The 1998 Mercury Grand Marquis, sharing its platform with the Ford Crown Victoria, exhibits a generally strong reputation for reliability, especially in its powertrain. However, like any vehicle of this age, certain issues are more frequently reported by owners. One common area of concern, particularly with higher mileage examples, is the transmission. Problems can range from rough shifting to complete failure, often necessitating rebuilds or replacements. The rear air suspension system, if equipped, can be a source of trouble, with leaking air springs or compressor failures leading to a saggy rear end. This can be costly to repair or replace, leading many owners to convert to conventional coil springs.
Another area to watch for is rust. While the chassis is robust, body panels, especially around the wheel wells, rocker panels, and door bottoms, can succumb to corrosion, particularly in regions that experience harsh winters with road salt. Electrical gremlins are also not uncommon. These can manifest as malfunctioning power windows and locks, intermittent dashboard lights, or issues with the climate control system. Spark plug blowouts have been reported on some 4.6L V8 engines, though this is more prevalent on earlier iterations of the modular engine. For the 1998 model year specifically, there weren't widespread major recalls that significantly impacted its long-term viability, but it's always advisable to check for any outstanding recalls with the VIN. Overall, with diligent maintenance, many 1998 Grand Marquis can achieve well over 200,000 miles, but attention to these common wear points is crucial for sustained reliability.

How long will the 1998 Mercury Grand Marquis last?
Based on owner data and anecdotal evidence, the 1998 Mercury Grand Marquis is known for its remarkable long-term durability. With regular and proper maintenance, including timely oil changes, transmission fluid flushes, and coolant replacements, it's not uncommon for these vehicles to surpass 200,000 miles. Many owners report consistently reaching 250,000 miles or even more. The robust chassis and proven V8 powertrain are the cornerstones of this longevity. However, weaknesses that tend to emerge over time include the aforementioned transmission issues, potential degradation of the air suspension system (if present), and the inevitable onset of rust on body panels in corrosive environments. Electrical components can also become more temperamental with age. Despite these potential wear points, the fundamental engineering of the Grand Marquis allows for extended service life, making it a dependable choice for those who invest in its upkeep.
What Technology & Safety Features are Included?
The 1998 Mercury Grand Marquis was equipped with technology and safety features that were standard for its era, focusing on comfort and basic driver assistance. Standard entertainment typically included an AM/FM stereo with a cassette player. Optional upgrades might have offered a CD player or a more premium sound system.
In terms of driver-assistance features, the 1998 Grand Marquis was relatively basic. Cruise control was standard, and a tilt steering wheel aided driver comfort. Anti-lock brakes (ABS) were a crucial safety feature, providing improved stopping power and control during emergency braking. For its time, this was a significant safety inclusion.
Safety was a priority, with standard dual front airbags for the driver and front passenger. The full-size, body-on-frame construction inherently provided a substantial level of passive safety. Optional safety features were limited, with the primary focus being on the standard equipment.
Crash-test ratings for this generation of Grand Marquis (and its Ford counterpart) were generally competitive for the time.
