Toyota service campaign 26TC03
Toyota filed this with NHTSA as a service campaign dated Aug 17, 2026, received Aug 12, 2026, about the engine — 5 documents under this number. It names 4 model years (2022–2025). A service campaign is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.
What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationIn wet conditions, water contacting the radiator in the subject vehicles after idling for an extended period can create steam that can cause an incorrect engine sensor reading. This can lead to a warning light, a rough-running engine, or a potential engine stall while idling or operating at low speeds.

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.

The manufacturer filed it against 4 model years: 2025 Toyota RAV4, 2024 Toyota RAV4, 2023 Toyota RAV4, 2022 Toyota RAV4. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
