I suspect a few things. First, let's address those marks on the bark. Those are called lenticels and are a normal part of all species within the Prunus genus.
Now, the first thing that I would do is test the soil for pH swings, and nutrient imbalances. These articles will help:

Usually, that will show you exactly what is wrong. In the case that the test come back within optimal ranges, you can move on to the next issue.
Overwatering throughout the tree's early planting can bring about disease. Cherry trees are sensitive to many diseases. Fungicides may be necessary. This article will help:
