Read by machine from the document NHTSA serves (7 pages), read Sep 30, 2026. A part number is shown only where it matches Toyota’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
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 2 model years this bulletin names have filed 95 complaints with NHTSA since 2015. 37 of them name Service Brakes — 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 a 2025 Toyota 4Runner. The contact stated that while driving at an undisclosed speed, there was an abnormal squealing coming from the rear brakes. No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the driver’s and passenger’s side rear brake pads.

Everytime I put my car in reserve the brakes screech so long. I have noticed it on other Land Cruisers as well. I am fearful of something happening with the brakes. Safety is obviously a priority and I have not seen anything from Toyota on this

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 T-SB-0046-25 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-SB-0046-25 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 T-SB-0046-25 cover?
The manufacturer filed it against 3 model years: 2025 Toyota 4Runner, 2025 Toyota Land Cruiser, 2024 Toyota Redundant Land Cruiser. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
