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 60,000 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.

The 2007 model year sits at the peak of the federal record, registering 48 complaints, 5 recalls, and 2 investigations—each figure the highest in the generation and substantially above the 22 complaints, 3 recalls, and 1 investigation logged for 2008. Across the arc, the trend declines sharply after 2007: recalls fall to 2 by 2011 and to zero from 2012 onward in the provided data, while complaints largely settle into single digits aside from a 17-complaint reading in 2013, confirming 2007 as the generation's most reported-upon year. Within 2007 itself, the highest complaint volumes are catalogued under Engine (10), Service Brakes (7), Visibility/Wiper (4), and Air Bags (3), with 3 crash-related and 1 fire-related complaint on file, though the data does not specify root causes. Because this model year carries the greatest concentration of federal complaints, recalls, and investigations in the record, it presents the least favorable risk profile of the generation. Buyers would be better served by a later year such as 2008 or 2012, which show materially lower complaints and zero recalls, so 2007 is not the strongest purchase candidate in this generation.
