Lexus filed this with NHTSA as a service bulletin dated Jul 30, 2025, received Aug 8, 2025, about the engine. It names 27 model years (2016–2025). 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 (6 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 27 model years this bulletin names have filed 70 complaints with NHTSA since 2015. 7 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.
Sudden engine stalling in the middle of a highway with extremely heavy traffic and stopped in the center lane. Needs to wait inside the car with a passenger in a very scary, tense situation and exposed to serious accident, until a towing arrive for about 1.5 hrs later. The car was towed to the dealer.

Unknown. Clicking sound coming from the passenger side of engine compartment by the vacuum pump. It occurs on cold starts and with the vehicle under load. I have video evidence of the sound. Not sure if it’s related but my breaks sometimes feel like they are not gripping as much

A rock is able to penetrate the huge weak grill and put a hole in the radiator causing dangerous overheating. My car overheated in a busy highway

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-0032-25 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-0032-25 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-0032-25 cover?
The manufacturer filed it against 27 model years: 2020 Lexus GS, 2019 Lexus GS, 2018 Lexus GS, 2017 Lexus GS, 2016 Lexus GS, 2025 Lexus IS and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
