Mercedes-Benz filed this with NHTSA as a service bulletin dated Jul 1, 2026, received Oct 9, 2024, about the structure — 2 documents under this number. It names 3 model years (2024–2026). 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.

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationComplaint Creaking/cracking sounds detectable in upper area of the side window panes Cause A locating rivet used during vehicle production to hold the side window pane in the correct position relative to the body- in-white. Remedy The rivet can be removed as follows: 1. Loosen upper molded part of seal from B-pillar bar and body-in-white flange → CAREFUL: Do not pull off too far (attachment 1). 2. Secure rivet set on back with butyl ball so that it does not become lost during next operation steps. Protect glass using doubled-up adhesive tape (attachment 2). 3. Bore rivet head from outside (drill bit diameter 8mm) and suction off shavings at the same time → CAREFUL: Avoid shavings falling between B-pillar bar and seal (attachment 3). Drive remaining rivet inward with a punch (d=3mm) (attachment 4) and remove. The butyl ball from Step 2 prevents it from falling down. 4. Seal opening formed by bored rivet head with a butyl ball d=4mm from inside to outside (attachment 5). Seal sanding spot at B-pillar bar against corrosion with black touch-up paint pen. 5. Fix seal in place at B-pillar bar again.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mercedes-Benz LI67.30-P-078468 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 LI67.30-P-078468 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 Mercedes-Benz warranty extension on file lists the ones Mercedes-Benz has filed.
Which vehicles does LI67.30-P-078468 cover?
The manufacturer filed it against 3 model years: 2026 Mercedes-Benz AMG GT, 2025 Mercedes-Benz AMG GT, 2024 Mercedes-Benz AMG GT. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
