Toyota filed this with NHTSA as a service bulletin dated Jun 8, 2023, received Jul 31, 2023, about the fuel/propulsion system. It names 22 model years (2020–2023). 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. 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.

What owners reported
Source: NHTSA complaint databaseOwners of the 16 model years this bulletin names have filed 2,666 complaints with NHTSA since 2015. 255 of them name Engine, Fuel/Propulsion System — 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.
The contact owns 2023 Toyota Rav4 Hybrid. The contact stated while driving at various speeds with 3 gallons of fuel remaining in the fuel tank, the message "Low Fuel" was displayed, and the instrument cluster turned blank. The contact stated that the instrument cluster remained blank and inoperable until fuel was added to the vehicle.
2023 Toyota RAV4 · Fuel/Propulsion System · filed with NHTSA Jul 8, 2024 · ODI 11600074
I purchased the car last July. Up to December, the car performed fine. Starting in December when I used the car heater repeatedly due to subzero temperatures, I noticed a burning smell coming from the vents. I was afraid that the engine or car would catch fire. I called the Tansky Toyota dealership and was told to bring the car in.
2022 Toyota RAV4 · Engine · filed with NHTSA Apr 22, 2023 · ODI 11518482
Highlander has same issue as the 2019-2020 Toyota rav4 fuel issue identified by the NHTSA: vehicle fuel gauges displaying less than full and/or total fuel dispensed is less than expected, when the fuel nozzle automatically clicks off. Noted the 'distance to empty' shown on the multi-information display is less than expected.
2021 Toyota Highlander · Fuel/Propulsion System · filed with NHTSA Apr 29, 2021 · ODI 11414525
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 TSB-0033-23 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 TSB-0033-23 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 TSB-0033-23 cover?
The manufacturer filed it against 22 model years: 2023 Toyota Highlander, 2022 Toyota Highlander, 2021 Toyota Highlander, 2020 Toyota Highlander, 2023 Toyota RAV4, 2022 Toyota RAV4 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
