This issue was discovered back in September.
After the production setbacks were resolved, early adopters of the 2020 Chevrolet Corvette Stingray have experienced a few teething problems with the mid-engine sports car. Shortly after customer deliveries started, videos emerged showing the frunk flying open while the car was being driven, blocking the driver's vision. Fortunately, this dangerous safety hazard has been fixed, but there's another issue with the car that still hasn't been resolved.
Back in September, the C8 Corvette was recalled after a problem with the electronic brake boost system sensor was discovered. Contamination in the material used in a sensor connection would cause the brake boost system to fail, making it much harder to brake and thus increasing the risk of having a crash.
This issue affects 679 Corvette models for the 2020 model year, along with the 2020 Cadillac XT4, 2021 Chevrolet Trailblazer, 2020-21 Buick Encore GX, and the new Cadillac CT4 and CT5. Affected cars have been placed on stop delivery since September 24. Several months later, Chevrolet still doesn't have a remedy for the issue, but a fix should be rolled out soon.
According to Corvette Action Center via Corvette Blogger, a GM technical document has been published with more information about the recall. However, the document only refers to the 2020-2021 Buick Encore GX and Cadillac XT4 being recalled and doesn't mention the 2020 Corvette, Cadillac CT4 and CT5, Chevrolet Malibu, or the Chevrolet Trailblazer.
GM describes the repair process as a "phased launch," so a remedy for the C8 Corvette and other affected models will be available at a later date. Owners of affected models who enter their VIN on the NHTSA website are still getting a notice saying "recall incomplete, remedy not yet available."
To rectify the issue, a dealer will need to replace the electronic brake boost module, but replacement parts are still in short supply. Customer deliveries for the 2021 Corvette Stingray have started earlier than expected, so let's hope Chevrolet has ironed out the kinks for new owners.
