2006 Nissan Xterra

The 2006 Nissan Xterra sits near the apex of this generation's federal complaint arc, posting 780 complaints, 5 recalls, 1 investigation, and 85 TSBs—the second-highest complaint volume across the 1999-2015 span and a sharp departure from the quieter 72 and 84 complaints recorded in 2003 and 2004. The generation traces a distinct three-phase pattern: a moderately problematic 2000-2002 stretch (161-231 complaints, peaking at 6 recalls and 3 investigations in 2002), a brief 2003-2004 lull, and then a pronounced 2005-2007 trouble peak that crested at 845 complaints in 2005 before collapsing to 119 in 2008 and to low double digits or fewer from 2009 onward. The 2006 complaint mix is heavily weighted toward fuel and powertrain systems—215 fuel-system, 114 power train, 77 combined engine/powertrain, and 64 fuel/propulsion filings—alongside 12 crash and 3 fire reports, though the underlying root causes are not specified in the data provided. Because 2006 is essentially co-equal with 2005 as the worst-case model year in this generation and is bracketed by demonstrably cleaner years on both sides, a buyer should treat it as an elevated-risk purchase and weigh it carefully against a 2003-2004 or post-2008 example, prioritizing a pre-purchase inspection of the fuel and powertrain systems.
