Toyota bulletin TTT073723
Toyota filed this with NHTSA as a service bulletin dated Aug 17, 2023, received Oct 16, 2023, about the communication. It names 145 model years (2017–2024). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.
What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationTT: A very small percentage of customers experience operational difficulties with some telematics features which they cannot resolve on their own. These resources, in conjunction with the Repair Manual, are for dealership personnel to assist those customers with user issues, user errors, and compatibility issues with other vehicle systems and external applications encountered while operating telematics features. Toyota has developed and provided the following Telematics Diagnostic Guide to assist dealer technicians.

Common questions
Source: NHTSA, 49 CFR 579.5Is Toyota TTT073723 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 TTT073723 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.
Which vehicles does TTT073723 cover?
The manufacturer filed it against 145 model years: 2024 Toyota 4Runner, 2023 Toyota 4Runner, 2022 Toyota 4Runner, 2021 Toyota 4Runner, 2020 Toyota 4Runner, 2019 Toyota 4Runner and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
