Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 2015 Acura RLX Sport Hybrid sits early in this generation’s federal record, right after a 2014 launch year that logged 1 complaint, 2 recalls, 3 investigations and a notably high 63 TSBs, and before 2016’s 2 complaints, 0 recalls, 3 investigations and 42 TSBs. Across the broader arc, TSBs decline sharply from 2014 onward (63 → 42 → 13 → 14), complaints remain in single digits, and recalls are sparse and intermittent, with 2018 showing 0 recalls but 3 complaints and 2019 returning to 2 recalls with 0 complaints. For 2015 specifically, the eight filed complaints cluster heavily in steering (5), with one each in structure, exterior lighting and suspension, and there are zero crash or fire complaints; the data does not specify a root cause for the steering reports. That places 2015 as a year with more owner-reported complaints than the adjacent 2014 and 2016 model years, yet no recorded fire/crash complaints and no recalls shown in the provided record. Bottom line: it is a conditionally acceptable year to buy, provided a pre-purchase inspection focuses on steering and suspension behavior and any open recalls are verified, though the steering complaint concentration warrants caution.
