2025 4Runner SR5 brakes squeal like dying banshee when cold

[bharri17]

The new 2025 Toyota 4Runner SR5 brakes are insanely loud when cold. It goes away after braking hard a few times (or about 5 minutes of driving), but you will turn every head in the city when leaving your parking spot. I have been told ad nauseam by my dealer that the brakes have a break in period (duh), but this is ridiculous.

I can reproduce the noise every single day after letting it sit for a few hours. Doesn’t matter going forward or reverse. It will squeal and make your ears bleed at the first few min of your drive. There seems to be no solution in sight, and I just have to slam on the brakes hard two or three times in the morning to make it stop.

Dealer says to just keep an eye on it, everything looks fine on their end.. I am dumbfounded.

Is there a TSB for this, or is it still too early for Toyota to admit or acknowledge anything is wrong?

A European banshee or an African banshee?

The same exact happens to me. Only while reversing though.

It started happening 3 days after I bought it. After parking my car (outside on my driveway) for a night, the truck squeals like a dying animal when I back out in the morning for work. This would happen to me may be 80% of the time.

I took it to my local dealer and they replaced the rotors and brake pads (same parts as the original). It was fine for the first few days and it is coming back. Not as often as I used to hear it. But It came back.

The dealer said that I had to wait until Toyota issues a TSB if this happened again with the new parts.

I read this is not just a SR5 issue. I heard this happens with other trims as well.

We all need to bug the dealers/Toyota so this gets a TSB and gets fixed before the warranty runs out or something...

It's a well known issue across multiple TNGA-F vehicles, brake squeal when cold, but no official fix yet afaik

Most people report it mainly in reverse though
