I have a perfect transmission too. I suppose if you come to a forum where people come to ask about problems, you end up reading about problems.
I have an 08 ES. I think they added lighting to the cabin after the 07 model year. I really like the interior lighting as it can be used while driving at night without interior "glare" like my old car's cabin lighting had. I also love the way it fades up at night as soon as I touch the engine stop button.
I have nothing bad to say about the nav system. I put addresses in my preset buttons and select them at will while driving. My voice commands work well, and I can call up POI's easily. Of course, I don't use my car in my job. But with all due respect, the last thing I want to worry about is my wife driving home from work on the highway while a real estate agent, speeding along in oncoming traffic, is busy typing addresses into their dash board.
I have had one rattle develop, but I know where it is. It's caused by the little square insert directly under the seat belt anchor on the side pillar. If you touch the insert, it moves in and out freely. I slipped a tiny sliver of felt in the seam (doesn't show) and it stopped the slight rattle and buzz I had when I cranked my ML audio system. I'll have the dealer look at it, as I'm sure most all ES' must have the same issue.
