Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The Acura ILX generation exhibits a general downward trend in federal complaints and recalls, moving from 65 complaints and 6 recalls in 2013 to just 3 complaints and 0 recalls by 2022. The 2020 model year falls near the end of this improvement arc, recording only 9 complaints, a sharp decrease from the 35 reported for 2019. Specifically, 2020 saw 2 recalls and 1 investigation, with the most frequent complaints involving Visibility/Wiper systems, though the data does not specify the root cause. While 2020 has more TSBs (75) than the final two model years, it maintains a minimal record of one crash complaint and zero fire complaints. Because it represents a period of significantly higher stability than the early-to-mid generation years, 2020 is a good year to buy.
