Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 2011 Acura RDX sits within a notably stable window from 2009 to 2012, with complaints ranging from 15 to 22 annually—among the lowest in the entire generation—and holding steady at 2 recalls per year with zero NHTSA investigations. This contrasts sharply with what follows: complaints surged to 161 in 2013, accompanied by the generation's first investigation, and peaked at 406 in 2015 before moderating. The 2011 model recorded 16 consumer complaints, 2 recalls, and 50 TSBs, with the top complaint area being air bags (9 instances), followed by electrical and exterior lighting issues (2). There was 1 crash-related complaint and no fire complaints reported. This positions the 2011 RDX as arguably the most reliable model year in this generation—post-launch bugs were resolved, yet the significant quality deterioration of 2013–2015 had not yet begun.
