Specs side by side
What owners say
H2
Overall
Sentiment is deeply polarized, split between strong affection for the vehicle's character and significant frustration with its ownership costs and reliability. Long-term owners express a passionate, almost irrational love for the H2's imposing presence, comfortable ride, generously appointed interior, and its capability as an "absolute unit." This is consistently tempered by very frequent reports of exorbitant operating expenses, particularly fuel consumption in the range of 10 mpg or less, and recurrent, costly electrical and mechanical failures. The vehicle is widely recognized as a competent and uniquely capable off-roader with serious hardware, but the consensus is that it was predominantly used as a suburban status symbol.
Best version to buy
Insufficient owner data available to designate a specific model year or trim as "best." Discussions reference 2003-2007 models without clear preference. The unique SUT (pickup) variant is mentioned but not comparatively evaluated.
Known issues
- ⚠Electrical system failures: encompassing parasitic battery drain, malfunctioning body control modules (BCM), door control modules, window regulators, dome lights, dash clusters, and stereo systems.
- ⚠Excessive fuel consumption: consistently reported at 10 mpg or less in real-world use. Frequency: very frequent.
- ⚠Costly and frequent repairs: owners report constant visits to the dealership costing at least $1,000 per incident, with major repairs like transmission failure cited at $8,000. Frequency: very frequent.
Xterra
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.
Known issues
- ⚠"Strawberry Milkshake of Death" (SMOD) Radiator Failure (2005-2010 Automatics): Radiator internal failure mixes coolant and transmission fluid, leading to automatic transmission destruction. Frequency: very frequent.
- ⚠Timing Chain Guide/Tensioner Failure (2005-2010): Plastic guides wear out, causing chain slack, potential timing jump, and catastrophic engine interference failure. Typically occurs around 60k-80k miles (97k-129k km). Frequency: recurrent.
- ⚠Automatic Transmission Issues (First & Second Gen): Rough shifts between 1st and 2nd gear, transmission failure, and general reliability concerns. Often linked to SMOD or age. Frequency: recurrent.
