2021 Toyota Prius AWD-e

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2021 Prius AWD-e.

Transmission Automatic (variable gear ratios)

The 2021 Toyota Prius AWD-e is EPA-rated at 54 mpg city, 50 mpg highway, and 52 mpg combined, and it uses an automatic transmission with variable gear ratios. In reliability records, this model year registers as a quiet entry: only six owner complaints have been filed, none have triggered recalls, and the top complaint area is the Fuel/Propulsion System. That concentration, alongside the absence of recalls, points to a comparatively stable model year with limited, narrowly focused owner-reported issues.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 10,000 mi; spark plugs at 120,000 mi; coolant every 50,000 mi. The big-interval services (every 50,000 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.

Owner complaints about the 2021 Toyota Prius AWD-e top in one area — the fuel/propulsion system, 1 of 6 reports (17%), well ahead of the next concern. NHTSA has issued no recalls for this vehicle, so these are owner-reported concerns only. 1 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the fuel/propulsion system pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
