Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 2018 Audi Q5 sits in a period where complaint volumes were relatively low from 2013‑2017 (ranging between 42 and 105) but then jumped sharply to 197 complaints in 2018, the highest single‑year total in the supplied data. Recall activity remained steady around five to six actions per year before and after 2018, with the 2018 figure of six recalls matching the surrounding years, and no federal investigations were recorded for 2018 or its immediate neighbors. This pattern suggests that while the 2018 model experienced an unusually high number of owner‑reported issues, those issues did not trigger additional recalls or investigations beyond the typical recall rate. Consequently, the 2018 year appears to be an outlier in complaint frequency rather than a sign of systemic safety defects. Takeaway: given the elevated complaint count for 2018, it may be less attractive to buy unless a specific, verified concern is addressed.
