Micra start stop issue

Sounds like a pain. Does it happen often? Maybe your battery is on its way out. Start-stop systems can be sensitive to low voltage.

Yeah, it's getting more frequent. Could a weak battery really cause all those symptoms?

Definitely. A heavily discharged or defective battery is the likely cause. Your car is fairly new but batteries don't last forever. Consider getting it checked at a workshop.

Thanks for the help. I had the battery tested, and you were right it was heavily discharged and defective. Replaced it for 290€ and the start-stop is working again.
