Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 2017 Acura RLX sits at the low end of the federal complaint and recall arc for this model line: complaints dropped from 83 in 2014 to just 3 in 2017, and recalls fell from five to none. Across the generation, the trend shows a steep decline in both complaints and recalls, peaking in 2014 and reaching a nadir in 2017 before a slight rebound in 2018 with one recall and six complaints. The 2017 year’s three complaints are distributed among steering/suspension, engine, and suspension/wheels/service brakes, with no crash‑related complaints and only a single fire complaint. This positioning at the bottom of the trend curve indicates that 2017 models were experiencing fewer reported issues than their predecessors, suggesting a mature and stable platform. Consequently, 2017 appears to be a solid year to consider purchasing a used RLX, provided the vehicle’s maintenance history and condition are verified.
