TSB for carbon build up for GS/ IS models 06-10 will now be warranted for 9 years unlimited miles. Just got my letter from Fresno Lexus. Guess who is going into Lexus tomorrow?

 

i got the letter also but had mine fixed last year just good to know that they admit its a problem and will cover it.

 

There's already a thread about this

but yes it's a great news. You do not need the letter to go there though. I took my car in and they're taking care of it. I'm just waiting for parts right now. I wonder if there will be any difference with the car after the CSP
