2008 Jeep Liberty — 3.7L

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

Body SUVEngine 3.7LTransmission Automatic 4-spd

The 2008 Jeep Liberty 3.7L is a compact SUV built on Jeep's KK platform, powered by a 3.7L engine mated to a four-speed automatic and EPA-rated at 16/22/18 mpg city/highway/combined; routine oil service calls for 5 quarts of 5W-20 API oil with the filter. Across the 2000–2012 model run, this year generated 540 owner complaints—below the 2002 peak of 1,807 yet far above the 2000 low of 6—with fuel-system, gasoline issues topping the list and five recalls issued. That complaint volume places the 2008 Liberty roughly in the middle of the generation's reliability history, suggesting a vehicle with notable concern areas but not the most troubled year in the lineup.

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.

In the Liberty generation, complaints peaked in 2002 at 1,807 and then fell steadily, reaching 540 complaints in 2008. Recalls followed a similar pattern, dropping from 14 in 2002 to 5 in 2008, with investigations declining from 10 to 1 over the same span. After 2008, complaints fell sharply to 108 in 2009 before rising again to 195 in 2010, indicating that 2008 sits on the descending side of the overall improvement trend. The top complaint areas for 2008 were Fuel System, Gasoline (90), Structure (53), Fuel/Propulsion System (49), and Electrical System (43), with 11 crash‑related and 4 fire‑related complaints reported. Given the lower complaint and recall counts relative to the preceding years and the continued downward trajectory into 2009, the 2008 Jeep Liberty represents a comparatively better‑model year to consider for purchase, though buyers should still verify service history.
