Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 2009 Acura MDX sits in a markedly quieter phase of the federal record after the high-volume early years. From 2001 through 2006, complaints ranged from 87 to 224 annually and recalls reached as high as 13 per year, with five investigations in 2003, 2005, and 2006; 2007 began a sharp downturn, and 2009 carries just 50 complaints, zero recalls, zero investigations, and 35 TSBs. Compared with 2008 (49 complaints, 1 recall, 41 TSBs) and 2010 (45 complaints, 1 recall, 77 TSBs), 2009 is the only year in that three-year window with no recalls and the fewest TSBs. Top complaint categories are electrical system (8), air bags (4), vehicle speed control (4), and power train (3), with 4 crash-related and 1 fire-related complaint, though the data does not specify root causes. The broader 2007-2013 arc stays low, but 2009 lands near its calmest point. Given its position at the bottom of the complaint/recall curve and no federal recalls or investigations on record, a used 2009 MDX appears to be one of the better model years to buy from a federal-file standpoint.
