Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 2015 Acura RDX sits at the peak of the complaint trend for its generation, with 406 complaints and 3 recalls, compared to 239 in 2014 and 431 in 2019. The recall count remains steady at three each year, while investigations rise to one in 2015, matching the 2013–2014 pattern. Exterior lighting accounts for the bulk of the complaints (319), followed by air‑bag issues (30). Crash complaints total seven and there are no fire complaints for the year. Given the high complaint volume and the concentration on lighting and air‑bag concerns, 2015 is a less attractive year to buy without a thorough inspection for those components.
