Which San Diego dealer are you taking it to?
I've had pretty good luck with Lexus San Diego in terms of working with Lexus Corporate to cover these type of costs.
You can also register as Lexus Owners to see if you under the CSP. You do not need the letter. If your VIN is within the range of CSP and you fall under 9 years from purchase date, you are covered along as it fits in their carbon build up criteria. If you are outside of 9 years, Lexus Corporate may still cover as goodwill but it is at their discretion.

I think you have a fair good shot at coverage since you're not that far off from 9 years.
Worst case would probably shared cost but hopefully not since this is pretty expensive fix.

troubled with my is250
I had the recall performed back in 2012 it is now 2015 my troubles are starting all over again. Going From second to first it jolts ( clunk to clunk ) . rpms jump sitting at a light, not always. I don't like being scared To drive it and being stuck somewhere. Is their another issue. I did call customer support and have them document this so if anybody else has this problem they will know.

same issue
Is it too soon to tell if Lexus's "fixed pistons" actually fixed the problem?
I have 121k miles on my 2010 (bought her new)--one of the last 2010's built that unfortunately is outside of the VIN range for the carbon TSB.
Starting at about 90k I noticed that at a stoplight the RPMs dropped from the normal 700 down to about 400, then shot up to about 1200 and instantly back to normal 700. Dealer ran the test and it passed.
It is now happening about 1-2 times per month. NO other issues or symptoms. I visit the dealer at least every 5k miles for an oil change.
There aren't many high-mileage 2010 1/2+ IS's on the road yet....
Dealer said he has had people bring their cars in and they had to run it 3-4 times over a 3-12 month period to get it to fail the test so Lexus could replace it.
This could be interesting....and I will definitely keep y'all posted on what happens.
I drive about 30k/yr for work and planned on keeping this until it hit 250k....now I'm getting scared it may not last that long.....and it will be paid off in 5 months.....ugh....

did you have the service performed on it and now its doing it again
Mine is shacking again too. Hasn't happened in months. Than all of a sudden 3 times this week. Its happening during idle only and I was sitting waiting at a red light. Once I put my foot on the gas pedal...gone. This would take forever to prove to Lexus dealer. But I guess I have to start sometime and bring it in for them to document it.

I promised I'd put pictures of the engine up a month ago... sorry for the delay, here they are!.
for those of you that have had reoccuring episodes, remember it can also be a factor how well the job was done to start with. Obviously this cylinder head got it's due attention.
CAVASOS, you say your car jolts as it downshifts from 2nd to 1st?? thats unrelated.. harsh shifts arent caused by this. you might have to look into other causes, sometimes its fluid contamination and a simple shift flare. The stumbling at idle, YES. take it back, they should do a top eng clean for you
Intake runner and top of valve
cylinder head before any cleaning
very little if ANY carbon build up on pistons, proof that the oil build turned carbon is on the other side of the valves
head cleaned, valves lapped, ready for install
a comparison of 3 intake valves
a close up of before and after

Missed recall by 6 weeks..
My 2006 IS250 has been having power issues (one time). I brought it and found I needed the rebuild people have been talking about. I missed the 9 years by 6 weeks and now have a $6000 rebuild bill. Thinking of having it done elsewhere (waiting for price)
Seeing if I can see this to Lexus as is
Keeping it as it and see if I have more trouble...
Any expert opinions ??

Very relieved as I really had no idea what I was going to do. Hopefully the repair will keep me rolling for a few more years.

Lexus IS250 intake valve carbon buildup fix/cleaning with Walnut Blasting
For those of you who may be outside of Lexus power-train warranty or TSB requirements, you might want to see if a local shop offers Walnut Blasting (walnut shell blasting) to help clean the intake valves.
I had seen it offered for BMWs (see blog post) and wondered if the same logic could work for us. My questions were answered when I stumbled upon a blog post about this carbon build up issue and found out that they were trying to engineer this service for Lexus IS owners.
Long story short, they did the Walnut Blasting process on my car and the results have been great! I have seen improved (nearly instant) throttle response and smoother idle.
In my opinion, something like this should be offered by the dealership as a part of ongoing maintenance. One thing to note is that I did have the intake cleaned and a couple pistons and valve rings replaced under warranty at 85k miles, had this Walnut Blasting process done at 118k miles and still noticed a significant gain in performance.
To read more about the process and view some photos of the results, check out the CARSpec Blog Post - Lexus IS250 and GS300 intake valve carbon fix/cleaning with walnut blasting.

Currently getting my car checked out at Stevens Creek. $155 if problem cannot be detected. Car rough started and died 3 times in 2 days, and intermittently comes to a rough idle at stop. So far it sounds like they can't detect that anything's wrong, no misfire codes. Are there any codes logged in the system?
