2005 Jeep Grand Cherokee — 3.7L

The 2005 Jeep Grand Cherokee sits at the top of a sharp complaint spike for this model run: its 2,051 NHTSA complaints are far above 2004’s 1,294 and 2006’s 1,297, and the total then falls steadily to 1,108 by 2007 and just 138 by 2009. Despite that volume, recalls were unusually low—only 5, versus 14 in 2004 and 6 in 2006—and investigations dropped to just 1, while TSBs rose to 117 before declining in subsequent years. The complaints are concentrated in the electrical system (680), structure (272), power train (143), and structure-related latches/locks/linkages (98), with 82 crash-related and 24 fire-related reports recorded, though the data does not specify root causes. Across the broader arc, this generation’s federal activity is front-loaded: high early complaints, low recalls, then a sustained decline through 2009–2010. That pattern places 2005 as the most reported and least formally remediated year of its generation. Given the combination of the generation’s peak complaint count, leading electrical and structural concerns, and limited recall activity, the 2005 model is a risky used-buy and generally not the best year to choose within this lineup.
