It does appear to only affect models outside the USA with the stop-start feature. But nonetheless, a great idea to tell everyone, since not everyone on the forum is in the USA.
As a result, any manual transmission models will not be affected, unlike manufacturers like Porsche who have the technology standard even on manual transmission models.
I believe Subaru has not implemented any stop-start feature for manual transmission models.
