What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 14 complaints with NHTSA since 2015. 6 of them name Electrical System, Power Train — 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.
My 2023 GMC Hummer EV 3X has experienced repeated thermal-protection failures in the high-voltage battery and drive-motor cooling system, causing the vehicle to enter limp mode and drop to as low as 12 mph without warning. Stored fault codes: P0C12, P0C13, P2EE0, P2EE1 (battery and drive-unit overheating).

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is GMC 24-NA-059 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 24-NA-059 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 24-NA-059 cover?
The manufacturer filed it against 3 model years: 2024 GMC Hummer EV, 2023 GMC Hummer EV, 2022 GMC Hummer EV Pickup. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
