It will be pretty similar to loads of different cars being on the Stellantis platform. It will be similar to Citroen, Fiat, Peugeot, probably others so a lot of mechanics will be familiar with it. Whether you need specialist dealer only diagnostic equipment for it, I wouldn't have a clue. Depends what's up with it, hopefully not electrical or something wrong with a 1.2 Puretech engine (if it has one of those).
