Lexus filed this with NHTSA as a service bulletin dated Apr 16, 2026, received May 8, 2026, about the power train. It names 5 model years (2022–2024).

Quoting the number at a service desk can save a diagnosis.

What owners reported
Source: NHTSA complaint databaseOwners of the 5 model years this bulletin names have filed 224 complaints with NHTSA since 2015. 22 of them name Power Train — 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.
Below is the email that I sent to both the manufacturer and the dealership: I hope your Christmas Eve was better than mine. My son and I were driving up to the Poconos to go skiing and I noticed the sonar detection light come on. When we were driving back from the Poconos, the transmission would not catch around the second or third gear.

Common questions
Source: NHTSA, 49 CFR 579.5Is Lexus L-SB-0009-26 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-0009-26 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-0009-26 cover?
The manufacturer filed it against 5 model years: 2024 Lexus NX, 2023 Lexus NX, 2022 Lexus NX, 2024 Lexus RX, 2023 Lexus RX. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
