Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2004 Liberty 2.4L.
The 2004 Jeep Liberty is a compact SUV built on the KJ platform, powered by a 2.4L four-cylinder engine paired with a 5-speed manual transmission that achieves EPA ratings of 17 city/22 highway/19 combined mpg, with maintenance requiring 5 quarts of 5W-30 API oil per service interval. Among the 1,100 total owner complaints filed for this model year—a figure that places it between the 2002 peak of 1,807 complaints and the 2000 low of just 6 across the broader 2000–2012 model span—suspension emerged as the most frequently reported problem area, complemented by 13 total recalls addressing various systems. This complaint profile indicates that while the 2004 Liberty experienced elevated owner dissatisfaction compared to the model's early years, the issues fell within a range the nameplate would continue to face throughout its production run rather than representing a dramatic departure.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 2004 Jeep Liberty sits in the early-generation arc after the disastrous 2002 launch year (1,807 complaints, 14 recalls) and a still-troubled 2003 (1,349 complaints, 13 recalls), showing meaningful improvement with 1,100 complaints and 5 investigations — though recalls held at 13 and TSBs rose to 70. Suspension dominates the complaint profile at 388 reports, followed by visibility (88) and fuel-system structure (53), while 86 crash and 39 fire complaints indicate safety-relevant concerns the data doesn't specify root causes for. The 2005 model year saw complaints tick up slightly to 1,118 with fewer recalls (8), and 2006 spiked again to 1,368, suggesting the platform's issues persisted beyond 2004. By 2007, complaints dropped to 703 with 7 recalls, marking the start of a sustained decline through 2012. The 2004 represents a modest improvement over the two prior years but remains in the high-complaint tier of the generation with significant suspension and safety-related reports. For a buyer, this is a below-average year to purchase unless the specific vehicle has documented suspension repairs and all 13 recall campaigns completed.
