That is great news, we just bought a new 2023 Avenir and made sure the heated seats were going to be retrofitted as to the Window sticker is indicating that. We also called our local dealer ( we bought our 2023 out of state at another dealer ) and our local dealer service department confirmed that yes ours will be retrofitted here in town. We also made sure the rear traffic detection was working as well as side path before we bought it as all of these options are now questionable as to ever being installed after October 10 2022, this per GM and Buick website
