1998 Dodge Dakota — 5.9L

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1998 Dakota 5.9L.

Body TRUCKEngine 5.9LTransmission Automatic 4-spd

Positioned as a truck on the AN platform, the 1998 Dodge Dakota 5.9L pairs its namesake engine with a 4-spd automatic transmission to deliver an EPA-estimated 13 combined mpg while running on 5.0 qt of 10W-30 or 5W-30 API oil. This model year has accumulated 574 total owner complaints and 12 recalls, with suspension issues standing out as the primary area of concern. Viewed within the broader 1990-2011 complaint history, the 1998 Dakota sits far closer to the problematic 2000 peak of 842 complaints than the 2009 low of 18, signaling a notably weak point in the model's reliability trajectory.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 15,000 mi; spark plugs every 60,000 mi; coolant every 30,000 mi. The big-interval services (every 30,000 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 1998 model year sits at the leading edge of a sharp escalation in federal complaints, recalls, and technical service bulletins for this generation: its 574 complaints, 12 recalls, and 110 TSBs represent a marked rise from 1996’s 216 complaints, 2 recalls, and 59 TSBs, match 1997’s recall count while exceeding its complaint volume, and foreshadow the climb to 690 complaints in 1999 and the eventual 2000 peak of 842 complaints. Across the generation, regulatory activity remained relatively moderate through 1996 before surging from 1997 onward and staying elevated through 2002, placing 1998 early in a steep upward arc. For 1998 specifically, suspension leads complaint categories at 177, followed by power train at 52, service brakes at 49, and engine cooling at 48, though the data does not specify root causes; the year also generated 45 crash-related and 1 fire-related complaint. Because 1998 initiates a sustained period of elevated complaints and recalls that worsens in subsequent years, it carries notably higher risk than pre-1997 models and is not a recommended year to buy.
