Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 7,500 mi; spark plugs every 90,000 mi; coolant every 45,000 mi. The big-interval services (every 45,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

In the decade preceding 2010, the Grand Marquis saw a steep rise in complaints—peaking at 487 in 2005—followed by a sharp decline to 78 in 2008 and 26 in 2009. The 2010 model continues this downward trend, registering 24 complaints, only marginally higher than the 2011 figure of 9, and maintains the low recall count of 2, consistent with the minimal recalls seen in 2008–2011. The top complaint areas for 2010—steering, structure, service brakes, and electrical system—are evenly distributed, each with three or fewer complaints, and there are no fire-related complaints, with only six crash complaints reported. Compared to the high‑complaint years of 2003–2005, 2010 sits near the bottom of the arc, suggesting a relative improvement in reliability. Therefore, a 2010 Mercury Grand Marquis represents a comparatively stable choice within its generation, though buyers should still scrutinize steering and structural components during inspection.
