What owners reported
Source: NHTSA complaint databaseOwners of the 5 model years this bulletin names have filed 151 complaints with NHTSA since 2015. 57 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.

2026 Toyota Land Cruiser · Service Brakes · filed with NHTSA Aug 3, 2026 · ODI 11754489
My 2024 Toyota Land Cruiser has exhibited persistent brake squealing since the day it was purchased. The noise occurs during normal braking conditions and has been present from the very first use of the vehicle. This is not a break-in issue, as it has never resolved on its own.

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.
