It names 2 model years (2022).

What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 21 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.
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.
2022 Lexus IS · Engine · filed with NHTSA Mar 3, 2024 · ODI 11575122
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
2022 Lexus IS · Engine · filed with NHTSA Dec 5, 2022 · ODI 11496172
There is already a service bulletin for the vacuum pumps on these cars, but it should be made into a recall because these pumps generate the vacuum needed by the brake system.

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 22LC02 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 22LC02 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 22LC02 cover?
The manufacturer filed it against 2 model years: 2022 Lexus ES, 2022 Lexus IS. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
