Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2018 MDX Sport Hybrid.
The 2018 Acura MDX Sport Hybrid is an SUV fitted with an automatic (S9) transmission, an engine oil capacity of 5.7 quarts using 0W-20 viscosity, and EPA fuel-economy ratings of 19 mpg city, 26 mpg highway, and 22 mpg combined. Within the 2017–2020 complaint history, this model year registers the lowest owner-reported grievances at just one—solely in the Visibility/Wiper category—alongside two recalls, compared to the 2017 model’s eight complaints. That data profile makes the 2018 model the most reliable year in that four-year window.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 2018 Acura MDX Sport Hybrid sits in a relatively clean stretch of the generation's federal record, with only one complaint filed compared to eight in 2017, eight again in 2019, and five in 2020 — making it the lightest complaint year in the four-year window. Its two recalls fit a clear downward trend across the generation (3 → 2 → 2 → 1), and its 21 TSBs represent a meaningful step down from the 32 issued for 2017, consistent with a maturing platform producing fewer servicing bulletins. The lone 2018 complaint centers on a visibility/wiper issue, which the data does not tie to a specific root cause, and notably the model year recorded zero crash and zero fire complaints — a reassuring safety indicator. One open investigation has persisted across all four model years, so it is worth confirming its current status with a dealer, but its static presence does not point to an escalating defect trend. On balance, the 2018 model year is one of the more attractive choices in this generation for a used purchase, though a pre-purchase inspection focused on wiper/visibility function and verification of completed recall remedies are sensible due-diligence steps.
