Lexus filed this with NHTSA as a service bulletin dated Mar 1, 2024, received Apr 15, 2024, about the equipment. 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.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. 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.

What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 49 complaints with NHTSA since 2015. 2 of them name Engine — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
The contact owns a 2023 Lexus NX 250. The contact stated that while driving at various highway speeds, the vehicle suddenly decelerated. During the failure, there was no warning light illuminated or messages displayed. The cause of the failure was not yet determined. The local dealer was notified of the failure.

Common questions
Source: NHTSA, 49 CFR 579.5Is Lexus 23LE05 NX450H+ M 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 23LE05 NX450H+ M 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 23LE05 NX450H+ M 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.
