Does this problem still exist or do I have a lemon?
Anybody had there engine CPU updated to prevent stalling? I had my IS350 for 2 months now and it stalled 3 times. All first start from not using it the previous day. When I talked to a mechanics at Lexus he had no clue.

"Found fuel saturation of engine oil with engine fuel long term correction of 15%, with no DTC recorded."
Toyota TCCS has the ability to apply a correction to the base fuel maps for the engine. I have some documentation and training materials describing this in detail, but from what I can tell, this forum isn't quite that technical. If you really want the details on fuel trim, PM me.
Essentially what this means is the ECM is adjusting the basic fuel calculations to 15% more fuel than it would normally expect, and no DTC (diagnostic trouble code) has been set. No DTC means all the sensors seem to be within normal operating parameters, and no broken wires have been detected by the ECM/ECUs.
On top of this, it seems that excess fuel is going into the oil. That's generally extremely bad for a lot of reasons. It's hard to imagine this happening because of a software error. I might take a look at this on TIS.
As of today, there is nothing in any Special Service Campaign bulletin about this. If they had identified a problem and a fix, it would be there.
