I have a 2007, owned for 3 years, have found all same 4 issues.
1 - Dash rattles - dash seems great quality but just a bit more creaky and rattley than I would have expected I just crank up the music volume drown it out !
2 - Non revving in Park = its Normal... the computer just doesn't let you do it, no problem.
3 - Blue smoke - hmmmm... I get a lot of this, too much IMHO really to be normal .. quite concerning, make wonder if the engine a suffers constant cold start/stop.
4 - Slight sensation of Judder/rumble thing when in neutral - yes I get that too, its a little odd, I think its probably just the hybrid system motors etc. doing something???
Amazing cars but not perfect.
