2009 Mercury Grand Marquis

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2009 Grand Marquis.

Body PASSENGER CARTransmission Automatic 4-spd

The 2009 Mercury Grand Marquis is a full-size passenger car equipped with a 4-speed automatic transmission, delivering EPA-estimated fuel economy of 19 mpg combined (16 city/24 highway) and requiring 6.0 quarts of 5W-20 API oil for maintenance. This model year represents a notably mature iteration of a long-running nameplate spanning 1990 to 2011, with complaint data showing the Grand Marquis reached its lowest reliability concerns by 2011 (just 9 complaints) while 2005 recorded the highest with 487—placing the 2009 model's 26 total complaints well below the historical average. The two recalls affecting this model year and a top complaint area in steering indicate some persistent mechanical concerns, but the overall complaint trajectory across the model's lifespan suggests the platform had largely stabilized by this point, offering a proven if unremarkable ownership experience rooted in over a decade of continuous development.

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.

The 2009 Grand Marquis sits at the quiet tail end of a generation that saw complaint volumes peak at 487 in 2005 before collapsing to 142 in 2006 and declining steadily to 26 in 2009, 24 in 2010, and just 9 in the final 2011 model year. Recalls held at a low two for 2009, matching both 2010 and 2011, while investigations dropped to zero from 2009 onward and TSBs stabilized at 16–17 across the final three years. The 2009 top complaint categories — Steering (5), Electrical System (3), Suspension (2), Tires (2) — reflect low absolute counts rather than systemic patterns, and the data doesn't specify root causes for any of them. With only three crash complaints and one fire complaint recorded federally, the 2009 model year shows no elevated safety signals relative to its immediate successors. This is a good year to buy if you prioritize a mature, low-complaint platform at the end of its production run.
