If you have bad carbon build up, you can always have a top engine clean done (few hundred dollars) if you're outside of the warranty. But as others have said, due to the design of the engine, carbon build up will always be more of a "when" then an "if" issue.

LIke others have said, changing the oil has little to nothing to do with the carbon buildup caused by poor design of the direct injection system in the IS250. Regardless of that, I think if you showed receipts of purchasing oil on a regular basis and changed it yourself, they cant hold that against you.
I think people's best bet would be to have a top engine clean performed every other oil change or 10k miles. This should greatly reduce the chance of carbon buildup getting so bad thta it causes performance issues. Some people swear by seafoam by having it injected into the intake manifold through a vacuum line, but if you're uncertain of the method just bring it to a reputable shop and have them do it for you. It should be a good and inexpenseive way to maintain the IS250 valves and rings.

I already went down that road with the same issue. I was fortunate to be able to work it out with the dealer. Long story short, the dealer did the repair on their goodwill.
Here is my story.

My story/experience may help you to win the battle. Just be nice and respectful. Do your research before negotiating so that they don't trick you into doing something unnecessary.
