Lexus filed this with NHTSA as a service bulletin dated Apr 17, 2024, received Apr 19, 2021, about the engine — 3 documents under this number: L-SB-0007-21 Rev1 (2 filings) and 1 more. It names 24 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.

Read by machine from the document NHTSA serves (7 pages), read Sep 30, 2026. A part number is shown only where it matches Lexus’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
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 24 model years this bulletin names have filed 281 complaints with NHTSA since 2015. 81 of them name Engine, Service Brakes, 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.
When I bought this car in 2019, I bought it in the summer time so I didn't hear anything so I bought the car. When winter came along and as it got colder out I notice that when I get up in the morning and cold start the car and when I put it on drive and pressed on my brakes there will be a squeeking noise coming from the brake...I told…

Coming down a steep, narrow, long driveway leading from a private home on a hill, and moving forward in low gear, I allege that the brakes failed. After 3-5 attempts at braking, we came off the cement driveway as we accelerated and slid off the side of the hill, turning over onto the driver's side of the car and coming to rest near a…

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Lexus L-SB-0007-21 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 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-0007-21 cover?
The manufacturer filed it against 24 model years: 2019 Lexus GS, 2018 Lexus GS, 2017 Lexus GS, 2016 Lexus GS, 2020 Lexus IS, 2019 Lexus IS and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
