What it saysDP: The subject vehicles are equipped with Lexus Safety Sense + (LSS+) which consists of several driving assist features, including pre-collision braking, lane departure warning, and more. NHTSA’s full summary ↓
Lexus filed this with NHTSA as a service bulletin dated Aug 29, 2023, received Oct 16, 2023, about the electrical system. It names 2 model years (2022–2023). 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 23LC01 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 23LC01 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 23LC01 cover?
The manufacturer filed it against 2 model years: 2023 Lexus NX, 2022 Lexus NX. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
