2012 Mazda CX-9

The 2012 Mazda CX‑9 recorded 221 consumer complaints, 4 recalls, 2 investigations and 289 TSBs, making it the highest‑complaint year in its generation when compared with the 86‑195 complaints recorded from 2007 to 2011 and the subsequent drop to 68 complaints in 2013 and lower numbers thereafter. The dominant issue in 2012 was service‑brake related, accounting for 124 of the 221 complaints, far outpacing airbag (19), engine (12) and suspension (9) reports, and while 9 crash complaints were filed there were zero fire complaints; the data does not specify a root cause for the brake complaints. Recall activity for 2012 (4 recalls) remained on par with the 6‑recalls‑per‑year average of the 2007‑2010 period, and the two investigations opened that year were fewer than the three recorded in 2010‑2011, suggesting the problem was not uniquely severe in regulatory terms. TSB volume in 2012 (289) is comparable to early‑generation years (277‑294) and lower than the later peaks of 577 and 512 in 2016‑2017, indicating that technical bulletins were not disproportionately issued for 2012. Across the generation, complaint counts fell sharply after 2012, reaching 68 in 2013, 54 in 2014 and 35 in 2015, while investigations dropped to one or zero from 2014 onward, pointing to an improving reliability trajectory in the model years that followed. Given that 2012 sits at the complaint peak of the CX‑9’s life‑cycle, especially for service brakes, and later model years show markedly lower complaint and investigation rates, a used 2012 CX‑9 carries higher reported risk than its successors and would not be the best choice in this generation.
