I've never run anything except premium in the car since I bought it new in 2007...91-93 octane from the good gas stations too. Mine was done April 2012. Search on here and you'll see I'm not the only one that still has this issue occasionally.

I was in the same boat as is250gurl as well, the dealership found evidence of carbon build up AFTER the repairs were already done. The response back from Lexus was something to the effect of "No further repairs recommended/authorized at this time". Longo Lexus was very helpful though and they really did try to get something else done....they collected detailed data and everything to try and get some sort of resolution.
For what is worth, I only used 91 gas from Chevron or Shell - sometimes Mobil. Was also using Mobil 1 full synthetic oil as well, still had the carbon build up show up shortly after the repairs.
Before I sold my car, I switched to 0w30 (still Mobil 1 full synthetic) and kept using 91 gas from Chevron or Shell and drove the car harder more often and noticed I wasn't experiencing the carbon build up symptoms much. In fact the last 10k miles I don't think I experienced any shaking or odd idle at all. Not saying this is the solution at all, it just happened to work for me. A few people have mentioned driving the car harder has helped.

I just picked up my vehicle this afternoon from Lexus of Escondido. I brought it in on Monday afternoon. It was ready within their 5 day promise of having those repairs done. My loaner was the new RX 350.
My SA, Adam, told me that they noticed some leaking from my water pump and that it was replaced at no cost (since my vehicle is still under warranty). I have exactly 85,000 miles on my vehicle, and this was the first time I had my water pump changed.
Since I live about 40 miles from Escondido, I got on the 15 fwy north and hit it all the way home. The first thing that I noticed was that my IS runs a whole heck of a lot smoother. It's quieter, especially when I hit some of those steep hills on the 15 Fwy and by my home. Another thing that I noticed was that it has more power.

Dealership asked if I was interested in looking at the new IS when I went in the other day. I said why would want another direct injection carbon nightmare since I see Lexus didn't change the engine it all? Silence after that and then "well the newer cars have the newer parts." Yes, so do I now and still carbon. No thanks!
Also tried to sell me throttle body and fuel injector cleaning. Hmmmm.....

So the dealer called today about my sisters 250 and guess what "They could not duplicate the problem" and they forced us to pay a $125.00 diagnostic fee. Needless to say I am very upset over this and called Lexus corp about paying for something that is a design flaw by Toyota/Lexus.

when I brought the paper out. Also after we paid we had to wait for 30 min before the car was brought out to us which leads me to beleive something is up as the gentleman after us received his GS within minutes after walking out.I also mentioned to Corp as to how they are going to handle this when IS250 owners have had enough of this issue and get together to form a class action lawsuit.

They claimed they did everything per what i printed ( I dont't trust dealers) out but they looked at me with a when I brought the paper out.

Any other dealers nearby? That's ridiculous they charged you.
