2023 Chevrolet Corvette

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2023 Corvette.

Transmission Automatic (S8)

The 2023 Chevrolet Corvette runs an 8-speed automatic transmission and an engine requiring 8.0 quarts of 0W-40 oil, with EPA ratings of 16 mpg city, 24 mpg highway, and 19 mpg combined. In the model's reliability history, the 2023 model accumulated 22 owner complaints and one recall, placing it toward the lower end of the 1990–2025 spectrum that peaked at 588 complaints in 2008 and bottomed at 8 in 1992. Despite that relatively low complaint volume, the Power Train category stands out as the top complaint area for this model year, a detail researchers should weigh when evaluating long-term ownership trends.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 7,500 mi; spark plugs every 97,500 mi; coolant at 150,000 mi. The big-interval services (at 150,000 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 federal record shows that complaint volumes for the Chevrolet Corvette peaked in the mid‑2000s (e.g., 536 complaints in 2005 and 588 in 2008) and have since declined to low double‑digit levels in recent years. Recalls followed a similar pattern, with multiple recalls in 2005‑2007 (up to six in 2005) and only isolated single‑digit recalls from 2010 onward. In 2023 the vehicle logged 22 complaints and one recall, which is comparable to the 2022 figure (20 complaints, one recall) and slightly higher than the 2024 figure (20 complaints, two recalls) but far below the historic highs. The trend indicates that 2023 falls within the current low‑incident phase of the generation’s complaint/recall arc. Consequently, based solely on the available complaint and recall data, the 2023 model year presents a relatively low‑risk option for a used Corvette purchase.
