Toyota bulletin T-TT-0801-26
Toyota filed this with NHTSA as a service bulletin dated Apr 16, 2026, received Apr 8, 2026, about the engine — 2 documents under this number. It names 5 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.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5; the full text comes from the manufacturer or a dealer.

Common questions
Source: NHTSA, 49 CFR 579.5Is Toyota T-TT-0801-26 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-0801-26 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-0801-26 cover?
The manufacturer filed it against 5 model years: 2026 Toyota Prius, 2026 Toyota RAV4, 2026 Toyota bZ, 2025 Toyota bZ4X, 2024 Toyota bZ4X. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
