It does not look that bad at all. no need to do anything at this time. check it every year and keep all photos. if it continues to grow then call in an expert . Bill
We should not be seeing landscaping above the black whatever they used for waterproofing ant the crack should be addressed just for the water leak if nothing else. That is not my expertise so hopefully some one will help you with best practice.
those cracks don't trouble me at all however its your house, not mine however, even if it were ours, i wouldn't be concerned,,, yes, there's probably been some foundation settlement but its not at the point of repair yet impo,,, pics & monitoring is good advice
