Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 6,000 mi; spark plugs every 30,000 mi; coolant at 102,000 mi. The big-interval services (at 102,000 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.

Within the 2004–2009 Durango generation, federal complaints peaked sharply at 1,567 in 2005 alongside 10 investigations, then declined steadily through 2007 (275 complaints) and into the target year. The 2008 model year recorded just 97 complaints, 2 recalls, and a single investigation — by far the lowest figures of the generation outside of the final 2009 model year (19 complaints), placing it at the tail end of a clear downward arc. This trajectory suggests that by 2008, most of the significant issues that drove the 2004–2006 spike — the data does not specify root causes — had been addressed through running production changes or prior recall campaigns. The top complaint areas for 2008 were Air Bags (20 complaints), Fuel System/Gasoline (19), and Fuel/Propulsion System (15), with 3 crash-related complaints and 2 fire complaints reported; the data does not indicate whether these share a common cause. With complaint volume at roughly 6 percent of the 2005 peak and minimal federal investigative activity, the 2008 Durango represents one of the safest picks within its generation — making it a reasonable used purchase, provided a pre-sale inspection confirms the two recall remedies were properly completed.
