Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2019 MDX Sport Hybrid.
The 2019 Acura MDX Sport Hybrid is an SUV pairing its hybrid powertrain with an automatic transmission (S9), and it carries EPA fuel economy ratings of 19 mpg city, 26 mpg highway, and 22 mpg combined. Service specifications call for 0W-20 viscosity engine oil with a 5.7-quart capacity, providing a useful baseline for researchers tracking maintenance patterns. Positioned in the middle of the 2017–2020 production run, this model year logs 8 total owner complaints — tying the 2017 high across the covered range and standing well above the single complaint recorded in 2018 — with the fuel/propulsion system as the most cited area and two recalls on file, a signal that the 2018 low did not hold and reliability has reverted closer to the generation's earlier levels.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
Across the 2017‑2020 span, the 2019 Acura MDX Sport Hybrid sits at a modest high point for complaints (8) and a low point for recalls (2) relative to its peers; complaints dropped sharply to 1 in 2018 before rebounding, while recalls fell from 3 in 2017 to a single recall in 2020. Technical Service Bulletins (TSBs) remain relatively stable, with 22 issued in 2019 versus 21 in 2018 and a larger 32 in 2017, indicating the model’s issues are being addressed without a dramatic spike. All three years maintain one federal investigation each, and the 2019 model reports no crash‑related or fire complaints, suggesting no emerging safety‑critical patterns. The complaint categories for 2019 focus on fuel/propulsion and power‑train components, but the data does not specify root causes. Overall, 2019 shows a balanced profile—higher complaint count than 2018 but fewer recalls than 2017—making it a reasonably safe year to consider, provided you verify any outstanding TSBs.
