2018 Dodge Durango — 6.4L

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2018 Durango 6.4L.

Body SUVEngine 6.4LTransmission Automatic 8-spd

The 2018 Dodge Durango is a full‑size SUV built on a rear‑wheel‑drive (WD) chassis and powered by a 6.4‑liter V8 that pairs with an eight‑speed automatic transmission, drawing 6.0 qt of 0W‑20 oil and delivering 18 mpg city, 25 mpg highway, and a combined 21 mpg according to EPA ratings. Its robust drivetrain is complemented by a relatively modest total of 228 owner complaints for the model year, with exterior lighting emerging as the most frequent issue and five recalls recorded. When placed against the Durango’s broader reliability record—from 1997 through 2026, where complaints peaked at 2,043 in 1999 and fell to just four in its inaugural year—2018 sits near the lower‑middle end of the spectrum, indicating a generally steady but not exceptional reliability standing for this generation.

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 96,000 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 third-generation Durango (2011–present) saw its highest complaint volumes and recall counts in the early years, with 797 complaints and 8 recalls in 2011, followed by a general decline through 2016–2017 where complaints dropped to 159 and 209, and recalls to just 3 and 2. The 2018 model year interrupts this downward trend with 228 complaints and a notable increase to 5 recalls, though it remains far below the generation’s initial peaks. After 2018, complaints fell again to 138 in 2019 and 53 in 2020, while recalls fluctuated, suggesting 2018 sits at a slight inflection point with elevated recall activity relative to its immediate neighbors. The top complaint areas for 2018 are exterior lighting (37) and electrical system (35), but the data does not specify root causes. Overall, the 2018 Durango is a mixed proposition: its complaint count is moderate and crash complaints are low (9), but the recall count of 5 is higher than the surrounding model years, so a buyer should verify that all recall repairs have been completed before purchase.
