2020 Chevrolet Corvette

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2020 Corvette.

Transmission Automatic (S8)

The 2020 Chevrolet Corvette routes its power through an 8-speed automatic transmission, with a powertrain specified for 7.5 quarts of 0W-40 oil and EPA ratings of 15 city, 27 highway, and 19 combined mpg. Owner feedback has been comparatively contained, with 34 total complaints and four recalls logged — the top complaint area being Structure — which positions this model year well below the Corvette's historical peak of 588 complaints in 2008 and closer to the low of 8 in 1992 across a complaint record spanning 1990 through 2025. That relatively modest complaint volume suggests this generation is off to a stronger reliability start than many of its predecessors, though the four recalls and structural concerns indicate it is not without issues.

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 2020 Chevrolet Corvette marks a distinct pivot point in the model's federal records, dropping from 147 complaints in 2019 to just 34, yet rising from 1 recall to 4. Across the broader generation, complaint volumes have swung wildly from historic peaks of 588 in 2008 down to double digits in recent years, placing the 2020 model at the onset of a highly stable, low-complaint arc alongside 2021 and 2022. However, the elevated 4-recall count for 2020 implies that while overall owner frustration was low, there were notable federal safety interventions required for this specific year. The primary complaint areas for 2020 are Structure (8), Power Train (4), and Engine (3), though the data does not specify the root causes for these issues. Ultimately, the 2020 Corvette is a solid year to buy provided you verify that all four recalls have been properly addressed, though buyers seeking maximum reliability might prefer a 2021 model which saw only 11 complaints and 2 recalls.
