I have a 2020 Subaru Forester and September 2020 I bought a device from autostopeliminator.com for $99. I just checked and they have installation instructions and it was very easy for me to install. I’ve been getting 28-29 mpg. I put up with start/stop for a few months but it became annoying. My car is almost 4 years old and I still have the original battery. I’m in Tucson AZ.
