INDIANA – 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).
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.
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.
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 vehicles:
- 2020 Corvette Stingray
- 2021 Corvette Stingray
GM has not clarified the number of Corvette units affected by this recall.
