A service update has already been sent to dealerships.

An unknown number of units of the 2023 Chevrolet Corvette were built with the wrong suspension calibration at GM's Bowling Green, Kentucky factory, GM Authority reports. All of the affected examples were shipped to dealerships, and it's likely some, if not all, have been delivered to buyers. GM has informed dealers of the situation via a service update.

Fortunately, it's not a serious issue and can be resolved in only a matter of minutes. The service bulletin sent to dealerships states that the affected Corvettes can be fixed by reprogramming the Electronic Suspension Control Module with the right settings.

No physical parts are required; this is solely a software issue and will be fully covered under the new vehicle warranty. The inspection itself will take only 12 minutes and the control module reprogramming will be completed in just 18 minutes.

How the problem was discovered remains a mystery but the report does not mention any instances involving a crash related to this problem. Chances are the calibration issue does not seriously affect daily driving and does not pose a serious risk. Owners are more likely to notice a difference during high-speed driving. Also, the bulletin does not state whether these Corvettes are the base Stingray or Z06.

We also checked the National Highway Transportation and Safety Administration (NHTSA) website to see if a recall has been issued. There isn't one as of this writing. 2023 model year Corvette production has been extended until September 1, 2023, we reported last month, and the '24 model year will begin rolling off the same assembly line a few days later on September 5. Typically, automakers conclude current model year production in June or July in order to allow time for any necessary factory re-tooling.

There are still unfulfilled Corvette orders, specifically for the sold-out Z06, that Chevy needs time to catch up, hence the extended '23 model year production. No major changes are expected for the '24 Corvette but there are rumors a major interior redesign is on the way.
