Service quick specs OEM factory data

Capacities, torques and tune-up values from the factory service manual.

This engine holds 4.5 qt of 5W-30 API engine oil, DOT 3 brake fluid. Torque lug nuts to 100 ft-lbs, the oil drain plug to 15.0 ft-lbs. The firing order is 1-2-7-3-4-5-6-8. Note the cylinder-head bolts finish on a torque angle (torque-to-yield) — they stretch permanently and should be replaced, not reused, during any head service.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the spark plugs every 100,000 mi; coolant at 150,000 mi. The big-interval services (at 150,000 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 2008 model year represents a mid-generation inflection point, posting 218 complaints—a rebound from 2007’s 164 yet significantly below 2006’s 330—while recalls moderated to three from the four recorded in 2006 and 2007. Federal data identifies Electrical System and Fuel/Propulsion System categories as the dominant complaint areas, accompanied by 26 fire complaints and 13 crash complaints, though the data does not specify root causes for these incidents. With federal investigations ceasing after 2008 and complaint volumes trending steadily downward through 2011, the model year sits at the tail end of the generation’s initial quality curve. This positions 2008 as a marginally riskier proposition than the subsequent 2009-2011 models, which saw complaints drop to 128 and below, but a notable improvement over the launch-year volatility of 2006. For buyers prioritizing reliability, 2008 is acceptable but not optimal; seek later model years or ensure documented service history addresses the electrical and fuel-system concerns that characterize this year’s federal record.
