Even if it's just a refresh of an older model, sales of the EcoSport are actually up in Europe compared to the same period last year.All those listed, including the EcoSport, are at the bottom of the sales charts of a huge growing segment in Europe. EcoSport is an old product on it's way out. Sales will continue to slow in preparation. Hardly a big concern.
By the end of 2018, the EcoSport was 6th in a segment made up of 30 models. Based on the first 2 months of 2019, it has overtaken the Opel Mokka which was previously at number 5.
The current EcoSport is doing ok for a model that (in your words) is an "old product", i'm sure the next gen model will do even much better.
