Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 2011 Acura MDX recorded 70 complaints, which is higher than the 45 complaints in 2010 but slightly lower than the 76 complaints in 2012, placing it in a modest upward trend after the low‑point years of 2009‑2010. Recalls were zero for 2011, matching the 2009‑2010 period and contrasting with the single recalls in both 2010 and 2012, indicating a lull in recall activity during this window. Investigations also remained at zero, consistent with the surrounding years. The top complaint areas for 2011 were Engine (21 reports), Power Train (5), Unknown or Other (5), and Electrical System (5), showing that engine‑related issues were the most frequently cited but still limited in number. Overall, the 2011 model sits between the very low‑complaint era of 2009‑2010 and the higher‑complaint years that follow, suggesting a reasonable balance of reliability for a used purchase. Consequently, the 2011 Acura MDX offers a favorable combination of low recall frequency and moderate complaint levels, making it a sound year to consider for purchase.
