Read by machine from the document NHTSA serves (6 pages), read Sep 30, 2026. A part number is shown only where it matches GMC’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.
Doing the repair yourself, or pricing it before the shop does? Search the part by fitment on eBay Motors — the listing and the price are the seller’s.

What owners reported
Source: NHTSA complaint databaseOwners of the 3 model years this bulletin names have filed 24 complaints with NHTSA since 2015. 16 of them name Electrical System, Forward Collision Avoidance — 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.
Automatic Emergency Braking engages when no object is present to hit. This has happened twice at lower speeds (roughly 20-30 mph). Parked cars present on side of road. Dangerous to driver and passengers as well as anyone behind the vehicle. Dealer hasn’t yet inspected the vehicle but that is pending scheduling
2024 GMC Hummer EV · Forward Collision Avoidance · filed with NHTSA Sep 11, 2026
While traveling with my wife and two toddlers over the July 4th holiday weekend, the 12 volt battery on my 2025 GMC Hummer EV failed completely at approximately 7,500 miles and five months of ownership. The vehicle would not accept a jump start and was disabled where it sat, stranding my family.
2025 GMC Hummer EV · Electrical System · filed with NHTSA Aug 15, 2026
The vehicle was no longer able to charge, and therefore could be stranded. Yes, the vehicle is currently back at the dealership and available for inspection. Without ability to charge, the vehicle could shutdown and not be able to restart. Yes.
2024 GMC Hummer EV · Electrical System · filed with NHTSA Sep 5, 2025
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-169 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-169 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.
Which vehicles does 24-NA-169 cover?
The manufacturer filed it against 4 model years: 2025 GMC Hummer EV, 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.
