2007 Mercury Mariner

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2007 Mariner.

Body SUV

The 2007 Mercury Mariner arrives as a compact SUV requiring 4.5 quarts of 5W-20 API oil, positioning it as the cleanest model year in a 2001–2011 run that peaked at 461 complaints in 2008. With just 33 total owner complaints and three recalls, the 2007 stands as the lowest-complaint year in the generation, though the Power Train still leads as the top complaint area. This relative quiet suggests the 2007 Mariner represents a reliability high point for the nameplate before complaint volumes surged the following year.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 5,000 mi; spark plugs every 100,000 mi; coolant every 50,000 mi. The big-interval services (every 50,000 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.

Across the generation, the Mercury Mariner exhibits a significant surge in complaints beginning in 2008, following a period of relative stability from 2001 to 2007. The 2007 model year falls at a low point in this arc, recording only 33 complaints, which is a decrease from the 63 and 67 complaints seen in 2006 and 2005, respectively. This stability is particularly notable when compared to the 2008 model, where complaints spiked to 461. For 2007, the primary complaint areas are the Power Train (9), Engine (5), and Electrical System (5), though the data does not specify the root causes for these reports. With only 3 recalls and 15 TSBs, the 2007 model is more stable than both the years immediately preceding and following it. Given its position as a low-complaint year before the 2008 spike, this is a good year to buy.
