Lexus filed this with NHTSA as a service bulletin dated Jan 26, 2024, received Mar 4, 2024, about the electrical system. It names 14 model years (2022–2024).

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 Lexus L-SB-0006-23 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-0006-23 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 Toyota warranty extension on file lists the ones Toyota has filed.
Which vehicles does L-SB-0006-23 cover?
The manufacturer filed it against 14 model years: 2024 Lexus ES, 2023 Lexus ES, 2024 Lexus LC, 2023 Lexus LS, 2023 Lexus LX, 2022 Lexus LX and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
