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.

What owners reported
Source: NHTSA complaint databaseOwners of the 4 model years this bulletin names have filed 997 complaints with NHTSA since 2015. 109 of them name Electrical System, Structure — 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.
On the 2016 Toyota Tacoma, the 24 owners who gave an odometer reading for Electrical System reported it at a median of 36,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
While driving on freeway at 65 MPH a sudden very loud noise was heard, initially thought it was a tire, but after verifying that the trucks stability was not lost (in just a couple seconds) then started feeling air coming from the top. Opened up the sun/moon roof cover and pieces of the glass fell.

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.

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. Every Toyota warranty extension on file lists the ones Toyota has filed.
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.
