@gblittle it usually take a while to get the notice and then it has a future date. Typical as they have to manufacture the new parts, get them to the dealers with instructions. I’d wait until you get the notice, going now is way to soon for something announced this week (unless you have other issues, then just add it to the list)
* you definitely want the updated part not the current (you can tell this by the last two letters (I.e., AA is the original, AB is the first update and forward. As an example in the case of the thermostat the problems didn’t calm down to AH)
