Lexus bulletin L-SB-0007-21 REV2
Lexus filed this with NHTSA as a service bulletin dated Jul 2, 2024, received Aug 8, 2024, about the engine — 2 documents under this number: L-SB-0007-21 Rev2. It names 28 model years (2016–2024). 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Lexus L-SB-0007-21 REV2 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 L-SB-0007-21 REV2 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.

The manufacturer filed it against 28 model years: 2019 Lexus GS, 2018 Lexus GS, 2017 Lexus GS, 2016 Lexus GS, 2024 Lexus IS, 2023 Lexus IS and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
