Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2022 RDX.
The 2022 Acura RDX pairs its 10-speed automatic with EPA ratings of 21 mpg city, 27 mpg highway, and 23 mpg combined, running on 0W-20 oil with a 5.1-quart capacity. On the reliability side, the model year has drawn just 30 owner complaints—led by an "Unknown or Other" category—and been subject to 2 recalls, both modest figures. Set against the RDX's 2007-to-2025 complaint history, 2022 lands well below the 431-complaint peak of 2019 and sits near the quietest year on record, 2024, with only 10 complaints filed. That places the 2022 model year among the more dependable iterations of the nameplate for anyone weighing long-term ownership.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 2022 Acura RDX sits at the low‑end of the generation’s complaint curve, recording only 30 complaints—far fewer than the spikes seen in 2015 (406), 2019 (431) and 2020 (338). Its recall count of 2 also trails the recent peak of 5 recalls in 2019‑2020, aligning instead with the modest 1‑3 recall range that has characterized most years since 2016. Technical Service Bulletins remain relatively high at 139, but this is a decline from the 223‑234 TSBs posted in 2019‑2020, indicating a tapering of emerging issues. The top complaint areas in 2022 are “Unknown or Other” and “Visibility/Wiper,” with no fire complaints and only four crash‑related reports, suggesting no major safety red flags. Overall, the data shows a downward trend in complaints and recalls for 2022, making it a comparatively safe year to consider for a used purchase.
