Toyota bulletin T-TT-0800-26
Toyota filed this with NHTSA as a service bulletin dated May 20, 2026, received Apr 8, 2026, about the electrical system — 2 documents under this number. It names 1 model year (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 communicationSome 2026 RAV4 HV vehicles may display a Distance to Empty (DTE) that is higher than expected at initial fill-up. The DTE is computed using the amount of fuel remaining and a learned value that is based on the average fuel consumption.

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-0800-26 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-0800-26 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-0800-26 cover?
The manufacturer filed it against 1 model year: 2026 Toyota RAV4. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
