NHTSA Complaint #11506152 — 2019 TOYOTA HIGHLANDER

There is a “squeak” type noise that sounds like fluid or air is being forced through a crack when the brakes are applied. It is intermittent as brakes remain applied, however it happens every time the brakes are applied and lasts until they are released. The local Toyota dealer diagnosed it as a failed brake master cylinder. After repair, the same noise continues. The dealers “master technician” was able to hear and reproduce the noise, but claim that it is from pressure building to help breaking. The young “master technician” stated that he works feel safe in the vehicle, but they don’t know why it’s making that sound. The sound began 1 year after I purchased the vehicle (I bought it v used in 2022). Warning lamps flashed very briefly indicating something about brakes, although it was difficult to read, as it happened very quickly and has not happened since.
