What owners reported
Source: NHTSA complaint databaseOwners of the 8 model years this bulletin names have filed 1,046 complaints with NHTSA since 2015. 309 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-TT-0753-24 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-TT-0753-24 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-TT-0753-24 REV1 cover?
The manufacturer filed it against 8 model years: 2024 Toyota Corolla, 2023 Toyota Corolla, 2022 Toyota Corolla, 2021 Toyota Corolla, 2020 Toyota Corolla, 2024 Toyota Corolla Cross and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
