Toyota bulletin 21TD03
Toyota filed this with NHTSA as a manufacturer communication dated Jan 6, 2025, received Oct 25, 2021, about the structure — 4 documents under this number: 21TD03 - Dealer. It names 4 model years (2016–2019). A manufacturer communication 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Toyota 21TD03 a recall?
No. A manufacturer communication 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 21TD03 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 21TD03 cover?
The manufacturer filed it against 4 model years: 2019 Toyota Tacoma, 2018 Toyota Tacoma, 2017 Toyota Tacoma, 2016 Toyota Tacoma. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
