GM bulletin PIC6486C
What it saysThis Preliminary information communicates to dealer that GM is aware of the issue and is working on a resolution. NHTSA’s full summary ↓
GM filed this with NHTSA as a service bulletin dated Oct 26, 2023, received Dec 4, 2023, about the communication. It names 25 model years across Chevrolet, GMC and Buick (2022–2024). 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is GM PIC6486C 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 PIC6486C 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 PIC6486C cover?
The manufacturer filed it against 25 model years across 3 brands (Chevrolet, GMC and Buick): 2023 Buick Encore, 2022 Buick Encore, 2023 Chevrolet Blazer, 2022 Chevrolet Blazer, 2023 Chevrolet Camaro, 2022 Chevrolet Camaro and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
