2008 Dodge Nitro — 3.7L

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2008 Nitro 3.7L.

Body SUVEngine 3.7LTransmission Automatic 4-spd

The 2008 Dodge Nitro is a compact SUV built on the KA platform and powered by a 3.7‑liter inline‑four, mated to a 4‑speed automatic transmission; it requires 5 quarts of 5W‑20 API‑rated oil and a filter for routine service. EPA estimates put its fuel economy at 16 mpg city, 22 mpg highway, and 18 mpg combined, reflecting the typical balance of torque and efficiency for a midsize SUV of that era. In the broader reliability context, the Nitro’s 2008 model sits within a decade of fluctuating owner complaints—peaking at 825 in 2007 and dropping to just one in 2005—while the 2008 model itself registered 393 total owner complaints, predominantly centered on electrical issues, and was subject to three recalls, signaling a moderate reliability profile for researchers assessing long‑term durability.

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; 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.

The 2008 Dodge Nitro occupies a midpoint in the model’s federal complaint trajectory, representing a sharp reduction from the 2007 peak of 825 complaints and eight recalls down to 393 complaints and three recalls, yet remaining significantly elevated above the generation’s subsequent low of 36 complaints in 2009. The generation’s arc shows a steep post-launch decline from 2007 through 2009, followed by a secondary rise in 2010-2011 complaint and investigation activity, positioning 2008 as a transitional year between initial production turbulence and later stability. For 2008 specifically, Electrical System and Fuel System, Gasoline complaints dominate the record at 88 and 61 filings respectively, accompanied by 17 crash-related and 12 fire-related complaints, though the data does not specify root causes for these incidents. While 2008 avoids the investigation intensity of 2007 and 2010-2011, it retains substantially higher complaint volume than 2009-2012 models and persistent fuel and electrical grievances. Given its position after the problematic debut year but with roughly ten times the complaints of the 2009 low-point, the 2008 Nitro represents a moderate-risk purchase requiring meticulous maintenance verification and comprehensive pre-purchase inspection.
