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 federal year-by-year record does not list 2010 itself, so direct annual comparisons are limited, but the surrounding arc is instructive: complaints fell sharply from 48 in 2007 and 22 in 2008 down to just 5 in 2011, while recalls dropped from 5 to 3 to 2 over the same window, placing 2010 squarely in a post-peak, declining-fault period. Target-year detail for 2010 shows only six top-category complaints, led by two structure/unknown-or-other reports and two air-bag reports, plus one each for fuel/propulsion and engine-cooling/gasoline fuel system, with two crash-related complaints and zero fire complaints. TSB counts in adjacent years were high—135 in 2008 and 198 in 2011—so dealer-service bulletins remained common, but recalls and investigations were already tapering. Compared with the later low-complaint years (2012, 2015, and 2017 each logged one complaint and no recalls), 2010 sits in a transitional middle phase: better than the relatively active 2007–2008 period but not as quiet as the very late model years. Given the low complaint severity, zero fire complaints, and the broader downward trend in recalls and investigations, 2010 looks like a reasonable used-buy choice, though a pre-purchase inspection should focus on air-bag and structural items referenced in those top complaint categories.
