I think you have to go to a Lexus dealership only, and yes you shouldn't have to pay for anything. Some members here have reported being charged for diagnostics and crap though anyways, though it should be covered. I would confirm with your dealership when leaving the car.

Took my '08 IS250 in the other day for the 65K maintenance. I've been working with a particular service advisor ever since I became a Lexus owner back in 2005. I started having very intermittent 'rough idle' about a year ago, but stressed 'intermittent'. Maybe once every two months so I didn't think much of it and then I 'stumbled' upon this thread and associated ones a while back.
About a week before my scheduled service appointment, the 'violent' rough idle occurred at the stop light. All the times this has happened in the past, including this time, nothing on the dash indicated anything wrong. And reading through threads, I thought at the time since there was no MIL/CEL, I wouldn't bring it up until it came on.
But on an off-shoot chance, I decided to tell my service advisor about the issue and told him I've been reading threads off CL about the 'carbon build-up' issue, but no MIL/CEL came on. He then said, "Oh. We have a couple tricks up our sleeves to make it misfire and pop the code for diagnosing it." -- Sure enough a bit later, he comes in a small office I took over to do work while waiting for my car and says, "We got it to misfire and the code. We're placing the order to have the pistons shipped from Japan which will take about 6-8 weeks to arrive and I'll give you a call when they're in."
Guess it's wait and see now but happy they were able to take care of it before it gets worse.
Cheers,
Kermee
P.S. Just for fun, I asked how much it would cost to have the fix done? He replied, "We're going to bill Lexus about 6K for it." and smiled...

I can wait 6-8 weeks and even my SA was disappointed it's been taking Lexus that long to get the replacement parts for the fix; It sounds like they've done a bunch of them. I'm virtually 99% sure that issues resulting carbon build-up won't cascade to any other system, at least in my instance.
Other than this, my experience with Toyota/Lexus has been overly positive starting with my '89 Toyota Van. And at least for me, they're fixing it.

As part of these type of programs (maybe specifically CSP), it is absolutely zero cost to you.
I made sure to reserve a courtesy car ahead of time so I wouldn't be stuck with another car rental agency's loaner.
Also, they refill your tank up when they are done, so be sure to arrive with your tank as close to empty as possible.

I got my car back this morning. SA said that they couldn't find anything and that my car didn't give any code. He also said that it might be my spark plugs thats giving me rough idles since my car has 61k on it. Just ordered some spark plugs and manifold gaskets from Sewells and will replace them next week, hopefully it will make a difference. If not I guess I can test drive a new ES or RX for a day or two haha.

I got a question for everyone...
How is replacing the pistons going to permanently fix the problem??? From what I have heard its a fuel injector design problem thats causing the carbon to build up? Even if they do replace them aren't they eventually gonna get dirty again?

On another note, I'm still waiting for my parts to arrive before I bring my car in to get this issue resolved. But in the mean time, I'm in love with how my car drives again after the top engine clean. Idles as smooth as butter, no rough idling or vibrations at all. And I used to get 26-27 mpg driving 50/50 highway/city, but now I'm getting around 29 mpg.

Since I last posted the wait time is longer more like a few months for the parts, my SA told me they had new ways of testing the car but we had to do it soon because it takes a very long time to get the parts back....in her word we have a very very long list to get this done.
