Has anyone encountered this yet with your new 4Runner? It’s starting to get humid here in FL and my new 4Runner squeals when I reverse out of my garage upon being “cold”. My Land Cruiser 259 has this same issue too. Toyota has made TSBs for this on the Tundra, Sequoia, and GX550…so it seems like it is a pattern for their new vehicles unfortunately.
 
We’ve had a few customers mention this with their new Tacomas, especially in humid areas from the Bay Area or after the vehicle’s been sitting overnight or for days at a time without driving. It’s a fairly common thing we’re seeing across Toyota’s newer platforms in general.

Typically, it’s just surface moisture or light rust buildup on the rotors causing the pads to squeal when reversing cold. It’s more noticeable in reverse because of the angle and light brake pressure. Driving more and letting the pads fully break in usually helps as the pads seat better and wear evenly, and the noise tends to fade over time.
 
I haven't noticed that yet but it's only been a couple of weeks. I'm south of Sarasota.

It's weird for sure. Cuz neither Taco of mine did it but the LC and 4R do. Strange.
