GM service campaign N242435631-03
What it saysCertain vehicles may have a condition where the battery is at risk for a drain following an over-the-air update. NHTSA’s full summary ↓
GM filed this with NHTSA as a service campaign dated Sep 11, 2024, about the electrical system. It names 12 model years across Chevrolet and GMC (2023–2024). A service campaign 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.

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.

What owners reported
Source: NHTSA complaint databaseOwners of the 12 model years this bulletin names have filed 2,407 complaints with NHTSA since 2015. 428 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.
The contact owns a 2024 GMC Sierra 3500. The contact stated while driving at approximately 60 MPH and towing a Forest River Riverstone Legacy 5th Wheel trailer, the brake pedal was depressed to slow for oncoming stopped traffic; however, the vehicle failed to respond as needed with the “Service Trailer Brake” warning light illuminated.

The GM brake controller will disconnect with the trailer being pulled. You get a message on the information center that the brake controller has lost connection with the trailer or no trailer brakes are available, something to that effect. This has happened up to 5 times in one day. You never know when this will happen.

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.
