Read by machine from the document NHTSA serves (8 pages), read Sep 30, 2026. A part number is shown only where it matches Toyota’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 4 model years this bulletin names have filed 42 complaints with NHTSA since 2015. 12 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.
The contact owns a 2021 Toyota Supra. The contact stated that while attempting to start the vehicle the engine did not immediately start and the message regarding a starter malfunction had displayed. The vehicle was later started and driven to the local dealer who diagnosed that the start needed to be replaced.

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.
2020 Toyota GR Supra · Electrical System · filed with NHTSA Jul 24, 2026 · ODI 11752727
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.
