Doesn't seem to be all 2020s and 21s. My 2021 shows no active recalls on the GM site.

GM has issued a voluntary emission recall for certain units of the 2020 and 2021 C8 Corvette Stingray due to a problem with the Transmission Control Module (TCM).
The problem: Affected TCM’s may incorrectly clear the loss of communications Diagnostic Trouble Codes (DTCs) when the vehicle is keyed off after detecting a loss of communications with other control modules.
The hazards: If the loss of communications fault persists, the TCM may not detect it again even after the vehicle is keyed back on. If this happens, the transmission could operate in a default mode with no DTC set and the malfunction indicator lamp not illuminated.
The fix: certified GM technicians will be instructed to inspect affected vehicles and reprogram the TCMS with updated software as needed. It should take techs less than one hour to complete the recall.
Affected components: Transmission Control Module (TCM).
Affected vehicles:
2020 Corvette Stingray
2021 Corvette Stingray
Number of affected vehicles: As of the time of this writing, GM did not clarify the number of Corvette units affected by this recall.
Owners should: GM will notify owners of affected vehicles and instruct them to make an appointment with their dealer. Any owners that are unsure whether or not their vehicle is affected by this recall can visit my.gm.com/recalls and type in their VIN to see any open recalls or other actions that may be active on it. Owners can also reach out to Chevy or the National Highway Traffic Safety Administration (NHTSA) directly with any questions or concerns they may have using the recall number and contact information included below.
