Chevrolet filed this with NHTSA as a service bulletin dated Sep 8, 2023, about the electrical system. It names 1 model year (2023). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 27 complaints with NHTSA since 2015. 7 of them name Electrical System — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
While operating my 2023 Chevrolet Corvette at approximately 75 mph on , the vehicle suddenly and unexpectedly lost propulsion. Moments later, the vehicle completely shut down. The instrument display went dark and the vehicle's lights went out. This occurred in active highway traffic.

Common questions
Source: NHTSA, 49 CFR 579.5Is Chevrolet N23-2407890 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the N23-2407890 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way. Every GM warranty extension on file lists the ones GM has filed.
Which vehicles does N23-2407890 cover?
The manufacturer filed it against 1 model year: 2023 Chevrolet Corvette. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
