Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 2019 Acura ILX recorded 35 complaints, 5 recalls, and 1 investigation, placing it above the 2017–2018 baseline of 20–23 complaints but well below the 2013 peak of 65 and the 2016 spike of 51. Its recall count of 5 is the highest since 2016, while the 83 TSBs issued reflects a generation trending downward from the 2016 high of 119. The top complaint category—Fuel System, Gasoline at 12 instances—represents a new dominant failure mode not seen in that position during prior years, though Service Brakes (7) and Service Brakes, Hydraulic (4) also appear prominently, suggesting brake-related concerns persist across the generation. The 2020 and 2021 data show a sharp decline in complaints (9 and 11, respectively) and a reduction in recalls (2 and 0), indicating the manufacturer addressed underlying issues in subsequent model years. The 2019 falls mid-arc in a generation that shows a gradual reliability improvement trajectory, with this specific year exhibiting a modest uptick in complaints but no fire complaints and only 2 crash complaints. A prospective buyer should budget for a thorough pre-purchase inspection of the fuel system and brake components, as these were the documented areas of concern for this model year.
