I can't wait to see when Toyota releases an official statement to address our concerns!
How sierra pointed out this only happening once temps reach 140f makes sense for why most people (my self included) only hear the chirping after a while of driving; what is also interesting about that statement is the insufficient lube in US gas causing the washer in the pump to start making noise; this could explain the differences of when people start hearing the noise (200mi or 900+ like others) as gas quality for 91 can even vary depending on gas station/ additives; I only started hearing the noise past 1k mileage using Chevron 91; overall sierra's post seems valid; just need an official manufacturer statement to put us all at ease =D

Most? Not sure about that..
Mine makes the noise and I only use 93.
