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 8 model years this bulletin names have filed 146 complaints with NHTSA since 2015. 13 of them name Electrical System — 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.
I purchased the 2022 Lexus RX 350 used a couple of months ago. While driving down the highway the instrument panel went blank. I was terrified. I continued to drive not knowing what speed I was driving. The instrument panel went panel came back minutes later. Another incident occurred when the car was parked in my driveway.

I am writing to you regarding the vehicle safety which I became aware of recently but there was no solution provided. IF this happened to me, it can happen to anyone driving the same model and needs to be addressed as soon as possible before the fatality occurs as this is danger to the public.

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 22LC01 Technical 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 22LC01 Technical 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 22LC01 Technical cover?
The manufacturer filed it against 8 model years: 2022 Lexus GX, 2021 Lexus IS, 2021 Lexus LC, 2021 Lexus LS, 2021 Lexus NX, 2021 Lexus RC and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
