Mine missed some journeys when it was first released but it’s been solid since. It behaves in odd ways although there’s some mildly tricky choices being made. For example, what a journey is - does it stop if you pull up to post a letter or do a quick errand? Or not capturing small journeys, I think it’s consistently not capturing anything less than 1km or so which is sort of reasonable until you stop near home to do a errand and that becomes your journey end. And that annoys me when I look at the data. Or, why it’s not recording the odometer reading or the SOC. Or why it’s not capturing charging?
