GM filed this with NHTSA as a service bulletin dated Mar 11, 2025, received Apr 15, 2025, about the forward collision avoidance. It names 16 model years across Chevrolet, GMC, Buick and Cadillac (2024–2025). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

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 16 model years this bulletin names have filed 1,400 complaints with NHTSA since 2015. 347 of them name 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.
I was driving on the freeway and was between two cars. The car on my right was trying to merge into me. I immediately was breaking while trying to control steering. I attempted to honk three times and my honk horn would not work. In a case of an emergency, that is absolutely unacceptable a car like this should be able to honk

2025 Chevrolet Suburban · Forward Collision Avoidance · filed with NHTSA Jul 24, 2025
I am writing to report a serious safety concern with my newly purchased. I believe this issue, if unaddressed, could lead to accidents. Specifically, when I am stopped at a stop sign with another vehicle behind me and the light changes to green, I begin to drive forward.
2024 Chevrolet Traverse · Forward Collision Avoidance · filed with NHTSA Dec 2, 2024
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 GM 25-NA-060 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-060 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-060 cover?
The manufacturer filed it against 16 model years across 4 brands (Chevrolet, GMC, Buick and Cadillac): 2025 Buick Enclave, 2025 Cadillac CT5, 2025 Cadillac Escalade, 2025 Cadillac Lyriq, 2025 Cadillac Optiq, 2025 Chevrolet Blazer and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
