Buick bulletin PIC6540J

Buick filed this with NHTSA as a service bulletin dated May 14, 2026, received May 19, 2026, about the unknown or other. It names 15 model years (2023–2026). 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.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5; the full text comes from the manufacturer or a dealer. 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. Quote it at a service desk; it is what the dealer’s system is keyed on.

Common questions

Source: NHTSA, 49 CFR 579.5

Is Buick PIC6540J 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 PIC6540J 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 PIC6540J cover?

The manufacturer filed it against 15 model years: 2026 Buick Enclave, 2025 Buick Enclave, 2024 Buick Enclave, 2023 Buick Enclave, 2026 Buick Encore, 2025 Buick Encore and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
