What it saysThis informational bulletin provides information on Information on Bright PVD (Physical Vapor Deposition) Wheels Appearance and Care. NHTSA’s full summary ↓
GM filed this with NHTSA as a service bulletin dated Sep 12, 2024, received Oct 22, 2024, about the wheels. It names 15 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.

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 24-NA-187 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 24-NA-187 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. Every GM warranty extension on file lists the ones GM has filed.
Which vehicles does 24-NA-187 cover?
The manufacturer filed it against 15 model years across 4 brands (Chevrolet, GMC, Buick and Cadillac): 2024 Buick Enclave, 2025 Cadillac Escalade, 2025 Chevrolet Silverado, 2024 Chevrolet Silverado, 2025 Chevrolet Silverado 2500HD, 2024 Chevrolet Silverado 2500HD and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
