Read by machine from the document NHTSA serves (6 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. Listings and prices on eBay Motors are the seller’s.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
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.

Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 228 complaints with NHTSA since 2015. 121 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.
It was around 7pm. It was raining & wipers were on. Auto stop/start setting is on. I was at a stop light waiting to turn left. The light turns green and I try to go, but the engine stalled. I was unable to move forward into the lane, and turn the wheel. A sign on the dashboard showed up saying "engine stopped, steering power low".

Common questions
Source: NHTSA, 49 CFR 579.5Is Toyota T-SB-0020-23 REV1 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-0020-23 REV1 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-0020-23 REV1 cover?
The manufacturer filed it against 2 model years: 2023 Toyota Corolla Cross, 2022 Toyota Corolla Cross. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
