Toyota bulletin T-TT-0755-24
Toyota filed this with NHTSA as a service bulletin dated Apr 10, 2026, received Jul 6, 2024, about the structure — 3 documents under this number. It names 3 model years (2024–2026). 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 communicationThe condition above is design intent for vehicles equipped with an accessory Power Port or Tire Inflator. During the installation process of the Power Port or Tire Inflator, the pre-wire connector is removed from the dummy cap (which is attached to the harness) and is left attached when power is connected. The purpose for the dummy cap is to prevent connector water intrusion/corrosion when the accessory is not installed.

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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Toyota T-TT-0755-24 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-0755-24 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 T-TT-0755-24 cover?
The manufacturer filed it against 3 model years: 2026 Toyota Tacoma, 2025 Toyota Tacoma, 2024 Toyota Tacoma. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
