GMC bulletin N24-245213

GMC filed this with NHTSA as a over-the-air update dated Sep 3, 2025, received Feb 26, 2025, about the unknown or other — 3 documents under this number. It names 4 model years (2023–2024). 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 communication

Certain 2023-2024 model year Chevrolet Colorado / Silverado 1500 and GMC Canyon / Sierra 1500 vehicles equipped with a 2.7L engine (RPO L3B), may have an Engine Control Module (ECM) that does not sufficiently control fuel injector flow rate under certain driving conditions. This update will complete the remedy for GM Recall No. N242452130 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.
