I have also reviewed the reminders. There was a behavior that annoyed me. The reminders couldn't be in the past. Now it's possible, hence you can have a reminder in the past until for instance you do a service.
Example: reminder all 5000 miles starting at 10'000 miles for a small service. If you have now 12000 miles a reminder will be activated with a notification at a date in the past. You can acknowledge it, but the reminder will still be in the list until you do a small service
