I'm at about 55k. Only issue I've had that wasn't aftermarket part related was the front brakes. Dealer replaced with the shitty Toyota pads (not the same as OEM). Squeaked like crazy. I had them replace them and re-surface the rotors again, but use the real OEM pads. (on their dime, not mine). Otherwise it's been gas, tires, oil, and a few issues with aftermarket stuff.
Stumbled across this...are you saying that if you go up to a Toyota parts counter and ask for a set of pads, you may not get OEM? I did a search and only found threads about aftermarket pads.
141k on my 2011. Drives like a dream but it has the 4runner “whine”. Almost sounds like a Ford power steering pump.
