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.

What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 404 complaints with NHTSA since 2015. 98 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.
When activating the blinker to make a right turn, after completing the turn the blinker turns off, but the force causes the lever to drop far enough that the left blinker activates. Since I've had the vehicle (about 8 months total), I notice this happen more than half the time I use the right blinker.

On May 8,2025 the lift gate failed and crashed down on my head, vehicle is available for inspection and only a GM inspector has looked at it so far. The dealership told me because I filed a complaint with GM they can't touch it unless directed by GM now.

Common questions
Source: NHTSA, 49 CFR 579.5Is GM 25-NA-024 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 25-NA-024 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 25-NA-024 cover?
The manufacturer filed it against 2 model years across 2 brands (Chevrolet and GMC): 2025 Chevrolet Equinox, 2025 GMC Terrain. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
