2004 Jeep Liberty — 3.7L

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2004 Liberty 3.7L.

Body SUVEngine 3.7LTransmission Automatic 4-spd

The 2004 Jeep Liberty is a KJ-platform SUV powered by a 3.7L engine and four-speed automatic transmission, a pairing that carried EPA ratings of 15/20/17 mpg and specified 5W-30 API oil at a 5-quart capacity including filter. Across the 2000-2012 model run, the 2004 model year accumulated 1,100 owner complaints, placing it below the 2002 peak of 1,807 yet far above the 2000 low of 6, with suspension standing as the top concern and 13 recalls issued. That positioning reveals a moderate-to-elevated complaint load relative to the generation’s documented range, meaning researchers should treat this model year as carrying a higher reported-issue exposure than the series low but not at the worst end of the KJ timeline.

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 2004 Jeep Liberty resides within a sustained period of high federal scrutiny that began abruptly in 2002, following two years of minimal activity. While the 1,100 complaints for 2004 are lower than the 2002 peak of 1,807, they remain substantially elevated compared to the 6 and 10 complaints recorded in 2000 and 2001. This model year carries 13 recalls and 70 TSBs, matching the 2003 recall volume but showing a reduction in investigations from the previous year's nine. Suspension issues represent the largest category with 388 complaints, and there are 39 fire complaints on record, though the data does not specify the root cause for these incidents. The complaint volume does not begin a consistent downward trend until 2007, placing the 2004 model in the middle of the generation's most problematic arc. Given the persistent high volume of safety and mechanical reports relative to later years, this is not a recommended year to buy.
