Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2021 NSX.
The 2021 Acura NSX pairs its core mechanicals—specified by a 9-speed automated manual transmission, an 8.3-quart 0W-40 oil requirement, and 21/22/21 mpg EPA ratings—with a strong dependability record. Across the nameplate's 1991–2021 complaint history, this model year registers just a single owner complaint categorized under "Unknown or Other" alongside zero recalls. This places the 2021 iteration near the model's historical low for issues, falling well beneath the 2017 peak of six complaints and signifying a notably trouble-free chapter for the vehicle.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 2021 Acura NSX is the final model year of the second generation (2017–2021), and the federal record shows a clear downward trend in complaints, recalls, and TSBs across that arc. Starting with 6 complaints and 3 recalls in 2017, the generation improved steadily: 2018 and 2019 each had 0 complaints, and recalls fell to 2 then 1, while TSBs dropped from 127 to 69. By 2020, complaints remained 0 with 1 recall and 39 TSBs, and the 2021 model records only 1 complaint (area unspecified), 0 recalls, 0 crash or fire complaints, and 25 TSBs—the lowest TSB count of the generation. The data does not specify root causes for the single complaint or the ongoing investigation (present each year from 2017–2021), but the consistent reduction in issues suggests Acura refined the NSX over its production run. This makes the 2021 a strong buy for a used example, as it represents the most mature and least problematic year of the second-generation NSX.
