GMC bulletin N23-242899
GMC filed this with NHTSA as a over-the-air update dated Feb 17, 2025, received Feb 25, 2025, about the unknown or other. It names 1 model year (2024). A over-the-air update is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.
What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationCertain vehicles may have a Brake System Control Module (BSCM) that does not correctly set a Diagnostic Trouble Code (DTC) or illuminate the Malfunction Indicator Lamp (Check Engine Light) if certain system faults with the potential to affect the vehicle’s emissions control system were to occur. Dashboard warning messages and warning lights for traction control, stability control, and brake system would remain functional in the event that a fault that could potentially impact drivability is detected. This update will complete the remedy for GM Recall No. N232428991 and no additional steps are needed after a successful update. You will also receive a letter providing additional details regarding this issue. During the update process, your radio may stay on up to 5 minutes after you exit the vehicle. This is expected behavior when an update package is onboard the vehicle. Do not service your vehicle during installation.
