What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationThe specific condition covered by this program is for a small engine coolant leak that can occur from the flow shut-off valve that can allow coolant to drip on other parts of the vehicle. This can cause "Engine Maintenance Required" to be displayed on the instrument cluster or cause the A/C not to function normally. Although the flow shut-off valve is covered by Lexus’ New Vehicle Limited Warranty for 48 months or 50,000 miles (whichever comes first), we at Lexus care about the guests’ ownership experience. Lexus is providing coverage for repairs related to Flow Shut-off Valve Coolant Leak
One of the 432 warranty extensions and special-coverage programs on file — every make, with the term each runs to.

Read by machine from the document NHTSA serves (10 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.
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 5 model years this bulletin names have filed 112 complaints with NHTSA since 2015. 9 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.
Driving car experienced a loud thump. Lost all engine power. Pulled to side of road. Had a hybrid system unavailable warning. Called a tow. Checked oil level to find it below the low mark. Car left a huge puddle of oil when loaded. Got to dealership. They found a hole in the engine block. Engine seized.
2019 Lexus ES · Engine · filed with NHTSA Mar 7, 2025 · ODI 11646961
The front timing chain cover on the engine was leaking at 53k miles. This is a 2GR-FKS engine. We have had the car for 19k miles, and bought it as a Certified Pre-Owned. We're looking at spending over 10% of the purchase price of the car on a repair, after barely having it for three years
2020 Lexus ES · Engine · filed with NHTSA Jul 8, 2026 · ODI 11749126
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 24LE02 a recall?
No. A warranty extension 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 24LE02 repair free?
A warranty extension is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does 24LE02 cover?
The manufacturer filed it against 5 model years: 2021 Lexus ES, 2020 Lexus ES, 2019 Lexus ES, 2020 Lexus UX, 2019 Lexus UX. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
