Cracks in the roof of the Marco Polo

[Fred]

We like our Mercedes Marco Polo 2016 very much but now we have a problem. There is a fracture (crack) in the beginning of the roof, outside, in the same place on the left and on the right side.
When the roof is on the high level, when we camp, the breaks are wider. We are now on holidays in Bosnie and Montenegro. We camp with the roof down. Anyone knows this problem? Is it possible to repair?

We had the same on our 2016, was just in for repair (warranty claim as we bought it second hand from a dealer). You need to find a shop that is good at fixing glass fiber.
