4. Yes.

From the OP,

Stellantis, which was created 4½ years ago from the merger of Fiat Chrysler and PSA Peugeot, is hoping to counteract some of the expected 1.5 billion-euro ($1.7 billion) cost of tariffs this year on cars produced in Canada and Mexico by boosting North American profitability with new model launches like the discontinued Jeep Cherokee.

A bit lefthanded, but at least part of the reason's provided before even asked for.
