It is my suspicion (opinion) that Honda will eventually provide the update to all CR-Vs in all states. Even in the current handful of cold states receiving the update, dealerships are waiting for parts. Now, imagine all the CR-Vs in warm states asking for the same parts at the same time...this is another total screw-up by Honda suggesting that even if you are eligible for the fix you can't get it unless you're physically located in an eligible state.

Documentation for the EXACT same Product Update in Canada claims it is at least partially to reduce oil dilution. I suspect (my opinion) that the lawyers at American Honda instructed PR to NOT use the term "Oil Dilution" in any written documentation to avoid future law suits.
