The short answer
Based on available data, the Nissan Xterra comes out ahead of the Jeep Liberty on power. Check the specs table and owner sentiment below for the full comparison before deciding between the two. Both are covered by real owner reports on CarWizz.
Overall
Owner sentiment is overwhelmingly negative, dominated by widespread reports of poor reliability, high maintenance costs, and subpar driving dynamics. The vehicle is acknowledged for its capable 4x4 system, good visibility, short wheelbase, and decent towing capacity for its size, which fosters a niche appreciation among some owners for off-road use and winter driving. However, this is heavily overshadowed by very frequent complaints about catastrophic rust (especially in unibody structures), numerous mechanical failures (engines, transmissions, suspension), persistently poor fuel economy (often cited as 15-18 MPG), and a general perception of being cheaply built with problematic electrical components.
Best version to buy
Insufficient owner data available to declare a consensus "best" version. Isolated opinions favor the 2002-early 2003 models for being lighter and having stronger internals, or the 2005-2006 Liberty CRD diesel for its torque and fuel economy (though with noted emissions-system reliability concerns).
Known issues
Overall
Sentiment is strongly bifurcated by generation and specific model years. The first-generation (2000-2004) and second-generation (2005-2015) Xterra are widely regarded as rugged, durable, and capable body-on-frame SUVs, often described as "tanks" and "well-built machines" that offer excellent value, particularly when compared to more expensive competitors like the Toyota 4Runner. Long-term owner reports frequently cite reliability, ease of DIY maintenance, and low-cost parts.
Best version to buy
Second-generation (2005-2015) models from 2011 onwards, as these are reported to have factory-addressed the major SMOD radiator and timing chain guide issues. The manual transmission variant is highly recommended to completely avoid SMOD and for perceived greater durability.

The verdict
The Nissan Xterra is the better choice for most buyers.
It has more power on its best-equipped version than the Jeep Liberty, based on the data above. If efficiency matters more to you than outright power, the Jeep Liberty is worth a closer look instead.
