    My has started making a 1-2 sec squeal about 10-30 secs after I start moving having just started the car. Sometimes it doesn't make this sound. It sometimes makes the same noise as I shut off the engine. Is this the inverter coolant pump going out? It sorta sounds like a slipping belt but not nearly as loud or annoying.

    This is probably the serpentine belt slipping on the air conditioner compressor pulley. Try turning the A/C button on and off to see whether you can force the noise to appear.

    If so, then you should have the belt replaced. The belt costs around $20 retail and is not hard to replace, maybe one hour of labor time or less. If you DIY, I suggest that you buy only the correct Toyota part.
