Krew just out of curiosity does Lexus ever make feedback driven changes between the time the media drives the vehicles and production? Im talking most about the downshifting delay on the 8 speed transmission which every single reviewer to date has pointed out as a major buzzkill. I understand no major transmission changes would probably be made but one or two reviewers said this could be corrected with a software update. Any thoughts?
I can answer with confidence that this is a no, unless the downshifting issue is a pre-production flaw.
The Camry V6 launched with a few complaints about the shift logic, and I'm sure the ES uses the exact same transmission. There have since been 2 TSiBs for the fix and Camry owners are quite happy now. I assume the ES should be good to go for production - maybe these were early prototypes that had not been reflashed for press drives (unfortunately).
These pre-production units that are driven during the press previews are not perfect, and it's possibly a flaw with these specific transmissions. However, it's also possible that the AI-shift software that learns driver preference is skewed by a couple weeks of auto journalists revving to the redline. This has been something I've noticed at past previews (the LS & LC specifically).
Then, as @Gecko says, perhaps this is something that will reach production and be resolved with a later mapping flash.
