What it saysThis Warranty Administration service bulletin provides Lithium-Ion battery Exchange Process and Transaction Submission information. NHTSA’s full summary ↓
GM filed this with NHTSA as a service bulletin dated Sep 4, 2025, received Sep 8, 2022, about the electrical system — 14 documents under this number. It names 114 model years across Chevrolet, GMC, Buick and Cadillac (2016–2026). 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.
One page for every brand it was filed under. Each brand’s bulletins: Chevrolet · GMC · Buick · Cadillac.

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 103 model years this bulletin names have filed 21,646 complaints with NHTSA since 2015. 13,676 of them name Engine, Electrical System, Fuel/Propulsion 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.
On the 2016 Chevrolet Malibu, the 172 owners who gave an odometer reading for Engine reported it at a median of 53,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

After about 5 minutes of searching inside the home and finding nothing, we realized that there was some smell of smoke coming from the garage and when the mudroom door which…

The entire left portion of the screen became inoperable and remained a black screen despite attempts to reset the system. The left side of the screen contains information such as gear selection, speedometer, lane keep assist, and many other important information. There is no other way to see what speed you are going besides this screen.

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 18-NA-180 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 18-NA-180 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 18-NA-180 cover?
The manufacturer filed it against 114 model years across 4 brands (Chevrolet, GMC, Buick and Cadillac): 2019 Buick LaCrosse, 2018 Buick LaCrosse, 2017 Buick LaCrosse, 2016 Buick LaCrosse, 2017 Buick Regal, 2016 Buick Regal and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
