Other cars with direct injection has the cricket noise also, maybe not all, or not in other places(higher octane gas?), but when I heared it on a kia w/di, and even on a lexus is(not sure is 250 or 350) that was idling, I was preety much convinced.
Some or most of us here is new to Direct-Injection technology, preety much the first car owned w/Direct injection, so we wear some thing not normal does not mean something is broken or something is wrong.

While I will agree that DI engines are far noisier than standard Port Injection, if there was not an abnormal noise coming from it, Toyota would have never released a TSB/ would have told everyone the noise is normal/ would not have spent how many dollars trying to come up with a fix for it. All the info I have gotten about the noise is that during intial assembly of the pumps, a certain part was not indexed correctly, cause the fuel to not route itself as intended causing the noise. There was nothing ever wrong with the design of the pump, hence the part number never changed. There were just defective when they were built.
