Periodic PCM Updates
Does Lexus issue periodic PCM updates for drivability improvements? I know a lot of other makes, especially GM will issue PCM updates throughout the life of a vehicle. When you take it in for service, they will check for updates and reflash the computer. As technologically advanced as these cars are, you would think the software engineers would be able to make a few tweaks here and there to squeeze out a little more performance in the algorithms as time goes by.

Yep, seems logical. I'm used to seeing a Technical Service Bulletin thread on most car forums, but with the reliability of these cars, I guess they are not as prevalent.

Mini Cooper is the king of PCM/ECU changes. Our 2005 started on version 31 in March of 2005. By October we were on version 43 before it was bought back as a lemon.
That was a rediculous example but they do happen. Not uncommon for the dealer to flash a new update while in for service.
