I disagree with your analysis
I disagree with your analysis. The Forester had a turbocharged version from 2004 through 2018 and people have been requesting a hybrid Subaru for almost a decade. It is highly unlikely that these two long-standing issues would suddenly make sales plummet in February- March of this year. I think the answer is simply that the profit margin is higher on the Crosstrek compared to the Forester, possibly because buyers are younger and are more apt to upgrade to higher trim levels. Subaru executives are simply choosing to make the vehicle in Japan that maximizes profits.
