2006 Dodge Durango — 3.7L V6

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2006 Durango 3.7L V6.

Body SUVEngine 3.7L V6Transmission Automatic 4-spd

The 2006 Dodge Durango stands as a full-size SUV built on the HB platform, offering a 3.7L V6 engine paired with a four-speed automatic transmission—a configuration that delivers EPA-estimated fuel economy of 14 city, 19 highway, and 16 combined mpg while requiring 5.0 quarts of 10W-30 API-rated oil for routine maintenance. With 851 owner complaints logged for this model year, the Durango’s reliability narrative is marked by recurring issues in the fuel system, a notable contrast to its lowest-complaint predecessor in 1997 but still a significant step down from the peak reliability concerns of the 1999 model. Positioned mid-pack in the vehicle’s broader complaint history, the 2006 iteration reflects a period of moderate dependability, though its ten recalls underscore persistent quality-control challenges that owners and researchers should weigh against its utility.

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 2006 Dodge Durango occupies a transitional position within its second generation (2003–2009), sitting just past the model's complaint peak of 1,567 in 2005 and 1,114 in 2004, but still well above the sharp decline that follows in 2007 (275) and 2008 (97). Despite the falling complaint count—851 versus the 1,567 high—2006 carries the highest recall total of the entire generation at 10, exceeding the 6 in 2003, the 9 in 2005, and the 4 in 2007, indicating that manufacturer-identified defects were actually more numerous as raw complaint volumes receded. The fuel-system complaint category dominates 2006 with 387 of the year's 851 filings, and the data also logs 16 crash and 9 fire complaints, signals that warrant pre-purchase inspection even though the JSON does not specify root causes for these failures. Investigations at 7 remain elevated relative to the post-2007 range of 1–4, placing 2006 in the higher-risk third of its generation. My takeaway: 2006 is a defensible buy only after a complete recall-verification check and a targeted fuel-system inspection, as it shows a better-than-peak but still meaningfully elevated federal record compared with the much cleaner 2007–2009 model years.
