Toyota filed this with NHTSA as a service bulletin dated Apr 9, 2024, received Feb 24, 2020, about the electrical system — 3 documents under this number: T-SB-0002-20 Rev1 (2 filings) and 1 more. It names 5 model years (2020–2024).

Quoting the number at a service desk can save a diagnosis.

There is currently an ongoing recall for the GR Supra over the starter. I currently drive a 2020 and have had periodic starter malfunctions. This is when I go to start the car it states starter system malfunction then lets me still turn it on after clearing the error message.

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 Toyota T-SB-0002-20 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 T-SB-0002-20 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 T-SB-0002-20 cover?
The manufacturer filed it against 5 model years: 2024 Toyota GR Supra, 2023 Toyota GR Supra, 2022 Toyota GR Supra, 2021 Toyota GR Supra, 2020 Toyota GR Supra. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
