2021 Hyundai Veloster N

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2021 Veloster N.

Transmission Automatic (AM-S8)

The 2021 Hyundai Veloster N is a performance‑oriented hatch built on Hyundai’s recent platform and mated to an eight‑speed automatic (AM‑S8) that delivers the model’s 20 mpg city/27 mpg highway/22 mpg combined EPA ratings while relying on a 4.2‑quart oil capacity and the recommended 0W‑30, 5W‑30 or 5W‑40 viscosities to keep its high‑output powertrain lubricated. Its reliability record shows a modest 16 total owner complaints, with lane‑departure issues topping the list and two recalls recorded, reflecting a noticeable drop from the 38 complaints recorded in 2019 and reaching a low of just two in 2020. Positioned in the middle of the 2019‑2022 complaint window, the 2021 Veloster N represents a comparatively stable year in the model’s early reliability trajectory, suggesting fewer systemic problems for researchers to contend with.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the spark plugs every 42,000 mi; coolant every 24,000 mi. The big-interval services (every 24,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

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 2021 Veloster N sits in the middle of a generation that saw a sharp complaint spike in the launch year (38 in 2019), a dramatic drop in 2020 (2 complaints), and then a rising trend through 2021 (16 complaints) and 2022 (24 complaints). This upward trajectory in complaints is mirrored by a similar increase in technical service bulletins, from 10 in 2020 to 22 in 2021, suggesting a growing number of documented issues. The 2021 model year is particularly defined by a concentration of lane departure complaints (7 of 16), though the data does not specify a root cause for these reports. With two recalls, one crash complaint, and one fire complaint, the 2021 Veloster N represents a regression in reported reliability compared to the notably quiet 2020 model year. While not as problematic as the launch year, this upward trend and the specific complaint pattern make the 2021 a less compelling choice than the preceding year.
